DESC:SANITARY WASTE MANAGEMENT SYSTEM AND METHOD THEREFOR

FIELD
The present disclosure in general relates to waste management systems and methods. Particularly, the present disclosure provides a sanitary waste management system and method therefor, specifically focusing on the disposal of sanitary waste through advanced incineration technology.

BACKGROUND
In India, over 1 billion used sanitary pads are disposed of every month, a number that is expected to increase. Inappropriate disposal of sanitary wastes such as sanitary pads, napkins, and diapers is a significant problem, leading to a rise in infectious diseases and other adverse effects. Conventional practices include dumping sanitary waste into landfills or water bodies, which negatively impacts the environment and adversely affects human health.
One prior art solution to mitigate the adverse effects of conventional disposal practices is the use of incinerators for sanitary waste disposal. Incineration reduces sanitary waste to ash within minutes, ensuring safe disposal. However, the current landscape of sanitary napkin incinerators can be broadly divided into two categories: decentralized/small-scale incinerators and industrial/large-scale incinerators.
Industrial or large-scale incinerators are equipped with advanced technologies that manage emissions and ensure complete combustion. On the other hand, small-scale sanitary napkin incinerators, often placed in common areas like schools, offices, and public restrooms, lack such sophisticated technologies due to cost and technological constraints. As a result, these small-scale incinerators face several significant limitations. They often fail to achieve complete combustion, leaving residual waste that requires further disposal. Additionally, they tend to emit smoke and hazardous gases during the incineration process, posing serious health and environmental risks. Moreover, they are not fully automatic, leading to the need for manual intervention, and are not well-designed for user experience.
In light of these challenges, there is a critical need for a sanitary waste management solution that combines the effectiveness of large-scale incinerators with the practicality and affordability required for small-scale applications. The present disclosure aims to address these issues by providing a sanitary waste management system and method that ensures complete combustion, minimizes harmful emissions, and is suitable for widespread use in various settings.

OBJECTS
It is an object of the present disclosure to provide a sanitary waste management system, that can address the afore-mentioned drawbacks and concerns of existing solutions for disposal of sanitary waste.
It is another object of the present disclosure to provide a sanitary waste management method that can address the afore-mentioned drawbacks and concerns of existing solutions for disposal of sanitary waste.
It is yet another object of the present disclosure to provide a sanitary waste management system and method that ensures safe disposal of the sanitary waste with minimal impact on humans and environment.
It is yet another object of the present disclosure to provide a sanitary waste management system and method that efficiently and effectively disposes the sanitary waste without manual intervention thereby addressing the user-safety issues present in existing technologies.
It is yet another object of the present disclosure to provide a sanitary waste management system and method that is user-friendly, eco-friendly and scalable, capable of handling varying volumes of the sanitary waste with ease.

SUMMARY
The present invention, in one aspect provides a sanitary waste management system for eco-friendly disposal of sanitary waste(s) by incineration. The system is compact, with zero-touch automation, and functions as an incinerator. The system comprises of an outer hollow structural framework defining a hollow space therewithin which encompasses a first chamber, a second chamber and an automated partition door therebetween. The system further comprises of a controller for automation and operational connectivity between afore-said components.
The first chamber comprises of a bin flap with a bin flap motor coupled thereto, a loading assembly and a sensor module operably coupled thereto. The bin flap motor facilitates in opening/closing operation of the bin flap to load the sanitary waste(s) therefrom. The bin flap remains open until pre-defined loading capacity is reached, after which it closes automatically to restrict further loading. The loading assembly includes a loading bin wheel with a loading bin wheel motor operably coupled thereto to facilitate rotational movement thereof. The loading bin wheel includes a plurality of compartment(s) to hold the sanitary waste(s). The rotational movement of the loading bin wheel is automated and facilitates in displacement of an occupied compartment with a vacant compartment to allow further loading of the sanitary waste(s), and this is continued until the pre-defined loading capacity is exhausted. The pre-defined loading capacity is no. of the plurality of compartment(s) available on the loading bin wheel to accept the sanitary waste(s) after setting aside 2 compartments as vacant in each cycle to ensure rotational clearance and safe loading/unloading. The sensor module includes plurality of sensor coupled to the bin flap and the loading assembly, and are positioned thereacross to detect presence of the sanitary waste(s) and maintain a count of occupied and vacant compartment(s) on the loading bin wheel. The sensor module assists in identifying when the pre-defined loading capacity gets exhausted such that any further loading thereafter is restricted by closure of the bin flap.
The second chamber is coupled to the first chamber and is positioned therein below to receive the sanitary waste(s) fed therefrom for incineration thereof. The second chamber comprises of a primary heater, an air-vortex unit, a blower, at least one thermocouple, and an exhaust assembly, operatively coupled to each other. The primary heater performs combustion of the sanitary waste(s) at a desired incineration temperature being in a range of 800- 900 °C to ensure complete incineration. The air-vortex unit is coupled to the primary heater to ensure a smokeless operation by generating cyclonic turbulence therein above. The air-vortex unit consists of 2 offset interlocking C-shaped plates that forms a spiral flow passage therewithin, which includes an open end with air inlet and a closed end opposite thereof, with top and bottom portion open. When air is passed via the air inlet through the blower, the air follows a circular trajectory path along inner walls of the air-vortex unit and collides with the closed end to form a recirculating vortex which generates a central recirculation zone above the primary heater thereby creating cyclonic turbulence therein above. This facilitates in enhancing flame stability and air-flame-flue gases (or smoke) interaction, and re-combustion thereof, thereby releasing cleaner gases into environment and making it a smokeless, emission-free disposal of the sanitary waste(s). The blower is operated continuously during the incineration, and provides air at a constant pre-defined air flow rate to support the incineration. The thermocouple monitors and helps in maintain the desired temperature of the primary heater for incineration. The exhaust assembly helps in releasing cleaner gases post incineration. Particularly, the exhaust assembly, the air-vortex unit and the primary heater are aligned one below each other respectively to form a continuous passage therewithin such that the sanitary waste(s) when fed from the first chamber falls through the exhaust assembly, then passes therethrough the air-vortex unit to fall under gravity within the primary heater for incineration, and thereafter smoke and flue gases undergoes re-combustion in the air-vortex unit such that cleaner gases are exited from the exhaust assembly.
The automated partition door is coupled to a partition door motor for opening/closing operation thereof to facilitate unloading of the sanitary waste(s) from the first chamber into the second chamber, via gravity.
The controller, being an electronic circuitry, facilitates automation and operational connectivity between afore-mentioned components and sub-components facilitating real-time monitoring the incineration of the sanitary waste(s) to ensure emission free and efficient operation. The controller facilitates in real-time safety and performance monitoring.
In another aspect, the present invention provides a sanitary waste management method for eco-friendly disposal of sanitary waste(s), using said system. The method is automated and initiates once the sanitary waste(s) is loaded via the bin flap by a user. The method thereafter includes detection of the sanitary waste(s) by the sensor module, and rotation of the loading bin wheel to displace occupied compartment with vacant compartment for another loading, until the pre-defined loading capacity is exhausted. Upon detection of the sanitary waste(s), in parallel, the primary heater is initiate heating, pursuant to which the blower initiates an air purge therewithin, and shortly thereafter the automated partition door opens to allow the sanitary waste(s) fall under gravity within the primary heater for incineration. The method is automated and is facilitated via the controller, and operates in continuous loop. The flue gases undergo re-combustion due to cyclonic turbulence created by the air-vortex unit, thereby releasing cleaner air into environment, while ash generated post incineration gets collected within an ash tray provided at bottom of the primary heater.
The system and the method facilitate in eco-friendly disposal of the sanitary waste(s) which is a low moisture-content semi-dry waste belonging to any category such as feminine hygiene product(s), adsorbent personal hygiene waste(s), non-hazardous biomedical sanitary waste(s) and bio-contaminated paper-based product(s).

Referring to figures 1 to 14, in one aspect of the present disclosure, a sanitary waste management system (1000), hereinafter referred to as “the system (1000)”, is disclosed. The system (1000) facilitates in eco-friendly disposal of the sanitary waste(s) without manual intervention, and with minimal to zero emissions.
Examples of Sanitary waste(s) compatible with the system (1000)

The system (1000) of present disclosure is compact, with zero-touch automation and functions as an incinerator for eco-friendly disposal of sanitary waste(s) by incineration. The system (1000) comprises of an outer hollow structural framework (100), which is an outer support framework (or structure) defining/ enclosing a hollow space/ area therewithin which encompasses a first chamber (200), a second chamber (400), an automated partition door (300) present between the first chamber (200) and the second chamber (400), and a control mechanism (or controller).
The outer hollow structural framework (100), in a non-limiting embodiment, is cylindrical in shape. The outer hollow structural framework (100), in an embodiment, is fabricated in metal preferably mild steel (MS), using heat/ thermal resistant material, and is further lined on inside with a thermally insulating material which surrounds the first chamber (200) and the second chamber (400). In an embodiment, the outer hollow structural framework (100) is fabricated using thermal resistance material such as ceramic material. In a non-limiting embodiment, the thermally insulating material is any one from ceramic wool and ceramic fiber blanket, offering high thermal resistance and minimizes heat loss thereby ensuring efficient and safer incineration. However, it is evident to a skilled person, that any other thermal insulating material can be used for fabrication. Further, the outer hollow structural framework (100) includes a protective powder coating shell covering from outside enhance durability and corrosion resistance.
The first chamber (200), which is a top portion of the system (1000), comprises of components including, but not limiting thereto, a bin flap (207), a bin flap motor (208), a loading assembly and a sensor module, and like components, being operatively coupled to each other.
The bin flap (207) is positioned at upper surface of the outer hollow structural framework (100) to facilitate loading of the sanitary waste(s) into the system (1000) by a user. The bin flap (207) is operatively coupled to the bin flap motor (208) to facilitate opening/closing operation of the bin flap (207) for loading of the sanitary waste(s) therefrom for disposal thereof. The bin flap (207) remains open to allow loading of the sanitary waste(s) therefrom until a pre-defined loading capacity/ threshold of the system (1000) is reached and automatically closes thereafter. That is, the bin flap (207) remains open for accepting the sanitary waste(s), and closes automatically when loading capacity of the system (1000) reaches the pre-defined loading capacity/ pre-defined threshold. The bin flap motor (208) facilitates opening and closing movement of the bin flap (207) based on the loading capacity of the system (1000). In a preferred embodiment, the sanitary waste(s) is inserted into a paper packet (for example, brown paper packet/ envelope which will be provided), having a fixed size and capacity, and then this paper packet containing the sanitary waste is loaded in the system (1000) to avoid jam issues. Each loading step will be performed the same way to avoid jamming/ disorientation issues.
The loading assembly includes a loading bin wheel (201) with a loading bin wheel motor (202) operatively coupled thereto to facilitate rotational movement of the loading bin wheel (201) for accommodating the sanitary waste(s) being loaded from the bin flap (207) operably coupled thereto. The loading bin wheel (201) is a rotating wheel being configured (or segmented) with a plurality of compartment(s) to hold the sanitary waste(s) continuously fed by the bin flap (207). The loading bin wheel motor (202) facilitates rotational movement of the loading bin wheel (201). The rotational movement of the loading bin wheel (201) is automated and facilitates in displacement of an occupied compartment with a vacant compartment to allow further loading of the sanitary waste(s) thereon. The bin flap (207) closes to restrict loading during each rotational movement of the loading bin wheel (201), and opens thereafter. The loading bin wheel (201) continues accepting the sanitary waste(s) until the pre-defined loading capacity is reached such that each of the plurality of compartment(s) of the loading bin wheel (201) gets occupied with the sanitary waste(s) pursuant to which the bin flap (207) closes automatically to restrict further loading. For the purpose of present invention, the pre-defined loading capacity/ threshold is no. of the plurality of compartment(s) that are available on the loading bin wheel (201) to accept the sanitary waste(s) after setting aside (or leaving behind) 2 compartments as vacant always in each cycle to ensure rotational clearance and safe loading/unloading operation. In a non-limiting embodiment, the loading bin wheel (201) comprises of 8 compartments for holding the sanitary waste(s)/ napkin. Particularly, the loading bin wheel (201) with 8 compartments will have the pre-defined loading capacity of 6 compartments being available to hold the sanitary waste(s) such that 2 compartments are always left vacant to accommodate for rotational clearance and safe loading/unloading operation. However, it is evident to a person skilled in the art, that the loading bin wheel (201) may contain a plurality of compartment(s) depending upon the requirement, and thus can have different loading capacity. In another embodiment of the present disclosure, the loading assembly includes a stationary loading bin (201a) in place of the loading bin wheel (201). The stationary loading bin (201a) serves as a collection bin and continues accepting the sanitary waste(s) until it is full of its capacity and thereafter the bin flap (207) is closed to initiate next steps. In this embodiment, while unloading of the stationary loading bin (201a), entire contents thereof are unloaded into the second chamber (400), i.e. the stationary loading bin (201a) is entirely unloaded (or emptied) for incineration of its contents together, and the bin flap (207) is closed to restrict loading until the automated partition door (300) is open. Once this batch gets incinerated, then another batch of the sanitary waste(s) collected in the stationary loading bin (201a) once full, is unloaded in entirety for incineration, thus single batch gets disposed in a single incineration cycle, as opposed to use of loading bin wheel (201) wherein one compartment of the wheel is emptied and undergoes incineration per incineration cycle, and then next compartment is unloaded.
The sensor module includes a plurality of sensor(s) being operatively coupled to the bin flap (207) and the loading bin wheel (201) and being positioned thereacross. The sensor module preferably includes sensor(s) such as, but not limited thereto, at least one photoelectric sensor (210) being an infrared sensor, at least one proximity sensor (209), and like. In an embodiment, the photoelectric sensor (210) is positioned across the bin flap (207) to detect the presence of the sanitary waste(s). The proximity sensor (209) and the infrared sensor (210) is positioned across the loading bin wheel (201) and the bin flap (207) to detect the presence of the sanitary waste(s) and initiate further process of incineration. The proximity sensor (209) installed on the loading bin wheel (201) facilitates in compartment position detection and management along with determining position of the automated partition door (300), whereas said infrared sensor (210) facilitates in detection of the sanitary waste(s) and counting the no. of occupied and vacant compartments of the loading bin wheel (201) to intimate when the pre-loading (pre-defined loading) capacity is reached/ exhausted, and pursuant thereafter the bin flap (207) closes. The sensor module detects presence of the sanitary waste(s) onto the compartment, and the loading bin wheel motor (202) controls the loading bin wheel (201) rotational movement, thus ensuring seamless loading. Further, the sensors upon detecting presence of the sanitary waste(s) loaded onto the loading bin wheel (201), signals the second chamber (400) to start heating.
The automated partition door (300) separates the first chamber (200) from the second chamber (400), and is configured therebetween. The automated partition door (300) is operated by a partition door motor coupled thereto and is monitored by limit switches (303) to facilitate opening and closing operation thereof for automatically pushing forward the sanitary waste(s) loaded in the first chamber (200) into the second chamber (400) for further incineration process without any manual intervention. The automated partition door (300) is designed to promote passive air circulation. The automated partition door (300) assembly consists of two MS plates, each with insulation layers, separated by an air gap in-between for improved thermal insulation. To further enhance airflow in this area, in an embodiment, a CPU fan is strategically placed nearby. Additionally, top surface of the automated partition door (300) —where the waste/ napkin rests—is fitted with a heat-resistant insulation gasket, providing an added layer of thermal sealing and operational safety. The sanitary waste(s) is unloaded from the first chamber (200) into the second chamber (400) by gravity (or free fall) as the automated partition door (300) opens. The automated partition door (300) acts as both a mechanical partition and a thermal barrier between the processing (incineration) chamber (i.e. second chamber (400)) and the loading bin wheel (201) assembly (the first chamber (200)). Its function is vital to maintaining temperature zones, ensuring component longevity, and improving energy efficiency. When the automated partition door (300) opens, the sanitary waste (for example, napkin) resting on it falls into the second chamber (400) by gravity.
The second chamber (400), is operatively coupled to the first chamber (200) and positioned therein below to receive the sanitary waste(s) being fed via the loading assembly for disposal by incineration. The second chamber (400) is an incineration (or combustion chamber) and comprises of components including, but not limiting thereto, a primary heater (401), an air-vortex unit (408), a blower (413), at least one thermocouple, an exhaust assembly (415) and like components operatively coupled with each other.
The primary heater (401) is provided to facilitate combustion of the sanitary waste(s) using high temperatures. In an embodiment, the combustion of the sanitary waste(s) is carried out at desired incineration temperature. Particularly, the primary heater is capable of maintaining a temperature of around 800 to 900 degrees Celsius (°C) which is the desired incineration temperature to ensure thorough incineration without any residual waste. In an embodiment, the primary heater (401) is a cylindrical ceramic electrical heater and it is technically separated from an ash tray (which is configured therein below) by a plurality of slant plates (405) (405) positioned at a 45-degree angle, placed parallel to each other at the bottom of the primary heater (401). In a preferred embodiment, but not limiting thereto, the primary heater (401) is a 3.5kW ceramic heater. Further, the slant plates (405) serve the following purpose:
• Ash Collection: During combustion, ash generated inside the second chamber (400) (i.e. heating chamber) falls by gravity through gap between the slant plates (405) directly into the ash tray. This ensures efficient ash disposal without interfering with the combustion zone.
• Radiative Heat Retention & Airflow Resistance: The slant plates (405) act as a physical barrier, reducing the downward flow of air and minimizing radiative heat loss toward the ash tray. This controlled airflow prevents the dispersion of flames or hot air away from the napkin and maintains optimal combustion conditions.
• Improved Combustion Efficiency: A small vertical ‘T-section’ stand (406) is welded at the center of the slant plate assembly. When the sanitary napkin (or the sanitary waste) falls into the second chamber (400), it rests on this central stand, which keeps it near the core of heating zone. This positioning ensures uniform 3D radiative heat exposure from all sides, leading to more complete and efficient combustion.
Thus, this characteristic design of the primary heater (401) of the present disclosure significantly enhances the thermal efficiency, energy utilization, and combustion performance of the heating chamber while ensuring clean and controlled ash handling.

The air-vortex unit (408), (or a cyclonic airflow system), is operably coupled to the primary heater (401) and is configured therein above to assist in efficient combustion of the sanitary waste(s). Particularly, the air-vortex unit (408) is provided to create intense cyclonic turbulence in the second chamber (400) to facilitate efficient combustion of the sanitary waste(s) and re-combustion of flue gases releasing cleaner gases into environment.
Design: The air-vortex unit (408) of the present invention is constructed using two interlocked C-shaped metal sheets, strategically arranged to create a controlled cyclonic airflow path. Each C-shaped sheet is curved to partially enclose an inner chamber, and the two C-shaped metal sheets (refer the drawing) are interlocked with an offset to form a spiral flow passage therewithin. The configuration results in a gradual inward spiral of the air path, mimicking the geometry of a cyclone separator or vortex chamber. One end of this spiral structure is open end having an air inlet (410) (to receive air from the blower (413) coupled thereto), while another end opposite thereto is closed (closed end), thus creating a dead-end or reflective wall to redirect airflow. Further, the top and bottom portion of the air-vortex unit (408) is also open.
Working mechanism: As the air enters through the air inlet (410), it follows the curved spiral path created between the 2 interlocked C-shaped metal sheets. The curved passage guides the air in a curved circular trajectory path, forcing it to spiral along the inner walls of the air-vortex unit (408). When the air hits the closed end of the air-vortex unit (408), it is forced to bounce back, and redirect therefrom resulting in a reverse spiral and recirculating vortex. This collision and redirection cause intense air turbulence within the second chamber (400), wherein there is downward flow of fresh air from the air-inlet (410) and upward flow of incineration process air-flame-radiative heat inside the air-vortex unit (408) that creates a cyclonic turbulence effect as shown in figure 9, thus creating a central recirculation zone (or vortex zone) above the primary heater (401). The centre of the spiral remains open, precisely sized to match the inner diameter (ID) of the primary heater (401), allowing hot air and flame to pass through vertically without obstruction. The top portion of the air-vortex unit (408) which is open, forms a central vertical exhaust outlet through which thoroughly combusted air and gases exit. The bottom of the air-vortex unit (408) aligns directly above the primary heater (401) allowing swirling air to mix directly with the flame and rising gases. The air-vortex unit (408) thus facilitates combustion of smoke and flames generated within the second chamber (400) during the incineration process, thereby reducing exhaust emissions by ensuring smoke is completely burned. Particularly, the air-vortex unit (408) induces a controlled swirling airflow when air is passed therethrough and the central recirculation zone causes cyclonic turbulence and promotes thorough mixing of air, flame, and flue gases, leading to complete re-combustion thereof and hence leading to smokeless emissions (or emission-free combustion) with minimal oxygen excess. More particularly, the cyclonic turbulence above the primary heater (401) enhances flame stability and air-flame-flue gases (or smoke) interaction leading to re-combustion thereof for transforming into cleaner emissions to facilitate smokeless and emission-free disposal of the sanitary waste, with minimal oxygen excess. The tangential vortex airflow ensures thorough combustion with minimal oxygen excess. For the purpose of present disclosure, the term ‘minimal oxygen excess’ refers to the condition during combustion where the amount of oxygen (or air) supplied is only slightly more than the stoichiometric requirement—i.e., just enough to completely burn the fuel, with very little unused oxygen left over.
Hereinbelow summarizing the characteristic design of the air-vortex unit (408), which causes upper and lower interaction as follows:
High-velocity air is introduced tangentially near the second chamber’s upper region, forming a cyclonic vortex governed by angular momentum conservation. This vortex exhibits:
• High turbulence intensity in the upper “vortex zone” above the primary heater (401), and
• Residual swirling airflow propagating downward toward the base of the second chamber (400), where solid-phase combustion of soiled sanitary napkins occurs (in the primary heater (401)), and
• While the air volume and velocity are maximized in the upper region, this swirling action persists to the bottom, enhancing air-fuel interaction with high-moisture, semi-organic materials like soiled napkins. This bi-directional flow by the air-vortex unit (408) ensures intense mixing of air and fuel (i.e. the sanitary waste) and hence facilitates- even and complete combustion (no unburnt fuel), minimal oxygen excess so flame temperature remains high and emission levels stay extremely low, uniform oxygen availability and Thermal entrainment of combustion gases.
The blower (413) is operably coupled to the air inlet (410) of the air-vortex unit (408) to continuously supply air (or oxygen) at a pre-defined air flow rate during combustion (or incineration) of the sanitary waste(s). In an embodiment, the blower (413) with a capacity of 1440 RPM is used. In a preferred embodiment, the pre-defined air flow rate is 2.9 to 3.1 m3 per 80 sec. This air-flow rate is maintained and is critical for achieving smokeless output. The blower (413) supplies oxygen to assist the combustion in the second chamber (400), and the blower (413) continues operation throughout the burning process. Particularly, the blower initiates an air purge supplied into the primary heater to provide oxygen required for the initial burning process of the sanitary waste(s). More particularly, the air is supplied twice for a brief duration (approximately 2–3 seconds), i.e. initial air purge is supplied, before the sanitary waste(s) (for ex. Napkin) is released into the second chamber (400) by unloading of one compartment of the loading bin wheel (201). This short burst of air is then stopped, allowing the napkin to fall into the second chamber (400) by gravity. Once the napkin enters the second chamber (400), the blower (413) starts and runs continuously for the entire incineration process. The blower (413) directs the air via the air inlet (410) of the air-vortex unit (408) into the primary chamber to support incineration, and the pre-defined air-flow rate is tailored such that turbulence is created therewithin. Specifically, smoke and flames generated during combustion combine with fresh air from the blower, inducing turbulence. This action ensures thorough combustion of smoke and gases, maintaining smokeless operation.
The at least one thermocouple is operably coupled to the primary heater (401) to monitor and maintain temperature in the range of 800- 900 °C during the incineration.
The exhaust assembly (415) is operably coupled to the air-vortex unit (408) and is configured in line therein above to facilitate release of flue gases in form of cleaner air into environment. In an embodiment, the exhaust assembly (415) includes exhaust pipes/ ducts and other sub-components that may be required to assist in functioning thereof. In another embodiment, the exhaust pipe is further configured with an exhaust pipe flap assembly (419) on exhaust outlet (418), wherein the exhaust outlet (418) pipes help release cleaner air into the environment. The exhaust assembly (415) may optionally include an exhaust gas treatment system integrated therewithin to further facilitate emission control treatment of flue gases, as a precautionary measure, prior to their release into the environment. Thus, the exhaust gas treatment system integrated within the exhaust assembly (415) may auxiliary contribute to facilitate treatments such as, neutralizing acidic gases, removing particulate matter, adsorbing dioxins and VOCs, diminishing NOx emissions to minimal levels and like, of the exhaust gases before releasing it out in the environment. The exhaust assembly (415) is fabricated using, not limiting thereto, heat-resistant materials to direct exhaust gases away from the incinerator and to ensure that treated, clean air is released into the environment. Particularly, it is a characteristic feature that the exhaust assembly (415), the air-vortex unit (408) and the primary heater (401) are aligned one below each other respectively to form a continuous passage therewithin such that the sanitary waste(s) fed from the first chamber (200) travels therethrough the exhaust assembly (415) and through the air-vortex unit (408) to fall within the primary heater (401) for combustion whereas flue gases after re-combustion induced by the air-vortex unit (408) exits therethrough via the exhaust assembly (415) releasing cleaner gases into the environment
The controller (or control panel), is an electronic circuitry adapted to facilitate automation and operational connectivity of components of the system (1000) and sub-components thereof thereby facilitating real-time monitoring the incineration of the sanitary waste(s) to ensure emission free and efficient operation. The controller functions as a monitoring system to oversees the entire incineration process, monitor emissions in real-time, and offer diagnostics for safe and efficient operation. In an embodiment, the controller includes an electronic system with various sensors and controls to allow service personnel or facility manager to monitor the system (1000) thereby providing real-time data on temperature, system status, and diagnostics. In an embodiment, the controller embedded within the system (1000) is a Microchip PIC Microcontroller as the core processing unit. This microcontroller handles real-time control logic, sensor interfacing, motor actuation, safety mechanisms, and combustion sequencing. In another example embodiment, core functional components of the controller include, but are not limited thereto:

Therefore, the system (1000) thus offers a comprehensive setup to facilitate in effective and environmentally friendly incineration process meeting stringent regulatory standards for emission control. The controller based on inputs received from the sensor module, automatically allows rotation of the loading bin wheel by one compartment to position an empty one for the next user to load the sanity waste thereon, thereby ensuring seamless loading. Further, upon detection of at least 2 compartments full/ occupied, the controller signals heating of the primary heater (401) to reach the desired incineration temperature, in parallel to loading operation, pursuant to which the blower (413) is activated, and thereafter the automated partition door (300) opens to unload the sanitary waste(s) for incineration, where all these steps are facilitated by the controller and are without manual intervention, thereby ensuring operational automation, with zero touch operation by the user.

The system (1000) of the present disclosure further comprises of an ash tray (500) configured below the primary heater (401) and is communicatively coupled thereto for collection of ash generated after each combustion/ incineration cycle of the sanitary waste. In an embodiment, the ash tray (500) is a Gravity-settling sealed ash tray (500) configured below the second chamber (400), and thus ensures no user is exposed to the ash. After incineration, the flue gases in form of cleaner air due to action of the air-vortex unit (408) exits therethrough via the exhaust pipe of the exhaust assembly (415) after passing through the air-vortex unit (408), whereas a small percentage of ash settles down within the ash tray (500). The ash tray (500), in an embodiment, is manufactured in metal to facilitate collection of the ash resulting from complete combustion of the sanitary waste(s). The ash tray (500) facilitates easy removal for disposal and cleaning thereof, allowing ease of operation.
The system (1000) of the present disclosure further comprises of at least one safety mechanism selected from thermal cutoff and emergency shut-off system(s), and like, to ensure safety in event of malfunctioning of the components of the system (1000). In an embodiment, the system (1000) includes safety mechanism such that thermocouple shut off 50°C body temperature. Further, the system (1000) of the present disclosure, in an embodiment, is manufactured using durable metal outer casing, lined with thermal insulation materials, to contain heat within the second chamber (400) ensuring energy efficiency and user safety. This also facilitates in protection of internal components from external damage. Enlisted below are few non-limiting examples of the safety mechanisms build-in the system (1000) of the present disclosure.
• Thermal safety:
o Dual Thermocouple Protection: Real-time monitoring of both heater and machine body temperatures.
o Automatic Overheat Shutdown: The system (1000) automatically powers down if the outer body exceeds 50°C, ensuring user safety at all times.
o High-Temperature Insulation- all heat-exposed components, including the primary heater (401) and the air-vortex unit (408) outer body, are insulated using high-grade ceramic wool. This significantly reduces surface heat, ensuring that the external body remains safe to touch during and after operation.
o Insulation Gasket & Body Insulation-The top portion of the automated partition door (300), where the napkin rests, features a heat-resistant gasket to block heat leakage and ensure safe napkin loading. Additionally, various critical sections of the machine are provided with multi-layer insulation, enhancing thermal containment and overall safety.
o Safe External Body Temperature - Due to effective insulation and heat management, outer body temperatures remain low, ensuring no harm or burn risk to the user even during extended operation. Heat-resistant ceramic insulation on outer body protects users from hot surfaces.
• User Safety & Hygiene: The automated loading mechanism avoids hand contact and open exposure. The loading bin wheel (201) rotates in a sealed environment and maintains compartmental separation, ensuring no backflow of smoke or ash. Combined with a thermocouple-based safety interlock, this mechanism guarantees operational hygiene and burn accuracy. Further, no Button Interaction- reduces contamination risks and mechanical faults.
• Mechanical safety:
o Flap Interlock Mechanism- The bin flap (207) automatically closes before the loading bin wheel (201) begins rotation, preventing accidental hand contact or napkin loading during movement.
o Compartment Positioning Sensors- High-precision proximity sensors constantly monitor and confirm the loading bin wheel (201) alignment, allowing rotation or unloading only when the position is correct.
o Napkin Jam Detection – Motor Overload Protection- If a napkin gets stuck inside the loading bin wheel (201), the system (1000) detects motor overload current, immediately halts all operations, displays the loading bin wheel (201) fault indication, and closes the bin flap (207) to prevent further napkin loading.
• Combustion Safety: Automatic Partition Door Interlock- The automated partition door (300) opens only when all conditions are safely met.
• Surface Cooling & Component Protection: CPU Fan Cooling- The CPU fan is installed near the automated partition door (300) to manage local heat dissipation, keep surrounding components cool, and maintain thermal stability of external surfaces.
• Emission Safety – Smoke-Free & Zero Harmful Gases

In another aspect of the present disclosure, a sanitary waste management method (2000), hereinafter referred to as “the method (2000)”, is disclosed. The method (2000) is explained in conjunction with components and sub-components of the system (1000), and facilitates in effective, eco-friendly disposal of the sanitary waste(s) by incineration without any manual intervention.
Referring to figure 14, the method (2000) begins at step (2010), with loading of the sanitary waste(s) in loading area/ loading assembly of the system (1000) by a user. The users of the system (1000) place the sanitary waste(s) into the loading assembly- i.e. within the loading bin wheel (201) or the stationary loading bin (201a). Particularly, the user loads the sanitary waste(s) into the system (1000) using the bin flap (207), which remains open to accept the sanitary waste(s). The bin flap (207) automatically closes facilitated by the controller, when the pre-defined loading capacity of the loading bin wheel (201) gets exhausted, or in case of the stationary loading bin (201a), when it gets full of the sanitary waste(s) and cannot accept any more waste. Once the sanitary napkin is detected, the bin flap (207) closes automatically to seal the compartment, and the loading bin wheel (201) rotates to bring the next empty/ vacant compartment to the top position for the user to continue loading thereon. This allows for continuous loading of up to, for example, 6 napkins in sequence, one by one, without user intervention. This loading is continued until the pre-defined loading capacity is exhausted. Each napkin is stored in a single compartment. After loading, the napkin is detected and the bin flap (207) closes; a new blank compartment rotates into position for the next napkin. This ensures hygienic, hands-free operation. It is pertinent to note that the further operational steps of the method (2000) remain same whichever loading assembly is used from the loading bin wheel (201) or the stationary loading bin (201a). The only difference is- when the loading bin wheel (201) is used, it rotates step-wise to displace occupied compartment with a vacant compartment, that is to expose a next empty compartment to allow further loading, and this continues until all of the compartments, except 2, are full with the sanitary waste. And further, when one compartment unloads for incineration, the loading bin wheel (201) once again accepts the sanitary waste, and this happens in a continuous loop. Whereas, in event the stationary loading bin (201a) is deployed, since it does not rotate, it acts as a simple collection bin to store all of the waste dumped thereinto such that incineration thereof happens in one go (all together). In case of the loading bin wheel (201), the incineration happens each compartment wise, and not all of the compartments are emptied together for incineration at once, although the operational steps below remain similar. Therefore, for explanation purposes, the method (2000) hereinafter is explained with reference to the loading assembly as the loading bin wheel (201) only, and with reference to sanitary waste(s) as sanitary napkin in an example embodiment.
At step (2020), the method (2000) includes detecting, presence of the sanitary waste(s) by an infrared sensor (210), being the photoelectric sensor, of the sensor module. Thereafter, in co-ordination with the proximity sensor and being facilitated by the controller, the loading bin wheel (201) is rotated by one compartment to position an empty one for the next user, i.e. rotation allows displacement of an occupied compartment with a vacant compartment. During each rotation, the bin flap (207) remains closed, and opens thereafter. This continues until the pre-defined loading capacity of the loading bin wheel (201) gets exhausted. The pre-defined loading capacity is no. of compartments available for loading after setting aside 2 compartments as vacant during each cycle to ensure rotational clearance and safe loading/unloading operation. That is, the loading and rotational movement continues, until all of the compartments of the loading bin wheel (201), except two compartments, gets occupied with the sanitary waste. Two compartments are intentionally left vacant to ensure rotational clearance. In event, the loading assembly is the stationary loading bin (201a), the loading is continued until the stationary loading bin (201a) gets full, such that it cannot accept any more waste. Thereafter, at step (2030), the
At step (2030), the method (2000) includes the controller, in co-ordination with the sensor module, at the backend, checks count of the sanitary napkin loaded in the system (1000), and only when the count is greater than 2 napkins, which means when at least 2 compartments of the loading bin wheel (201) are occupied, next step is initiated. In event the count is less than 2, the controller waits until at least 2 compartments are occupied with sanitary waste(s), before initiating the next step.
At step (2040), the method (2000) includes concomitantly, initiating activation of the primary heater (401) upon detection of the sanitary waste(s) by the sensor module, in parallel and being facilitated by the controller, wherein the primary heater (401) initiates heating to reach a desired incineration temperature being in range of 800- 900 °C. Preferably, when the sensor system confirms that at least two napkins have been loaded (or at least 2 compartments are occupied), a signal is sent via the controller to the primary heater (401) which activates and begins preheating to the targe/ desired temperature range (800–900°C), which is desired incineration temperature. In event the stationary loading bin (201a) is used, this step will be initiated upon detection of at least 2 sanitary napkins/ products.
This is pre-heat phase, where the system (1000) continues to accept additional sanitary napkin(s) until the pre-defined loading capacity is reached. Loading operation continues until the primary heater (401) attains the desired incineration temperature, or until the pre-defined loading capacity is exhausted, whichever is earlier. That is, if the napkin count has reached the pre-defined loading capacity which has been exhausted, and the primary heater (401) has still not attained the desired incineration temperature, the bin flap (207) automatically closes and no further napkins/ waste is accepted until the count drops to, in this example, drops to five or below, i.e., specifically until count drops below the pre-defined loading capacity. Once the target temperature is reached, the system (1000) disables further loading by locking the bin flap (207), preventing exposure during combustion.
At step (2050), the method (2000) includes activation of the blower (413) to initiate an air (or oxygen) purge, initial oxygen purge, being supplied through an air inlet (410) of the air-vortex unit (408) to the primary heater (401), being facilitated by the controller.
Thereafter, pursuant to the primary heater (401) attaining the desired incineration temperature (step (2060), the method (2000) subsequent thereafter includes opening of the automated partition door (300) by the partition door motor for unloading by gravity (or free fall) of the sanitary waste(s) into the primary heater (401) of the second chamber (400), being facilitated by the controller (steps (2070, 2080). The automated partition door (300) opens only when the controller at the backend detects that the primary heater (401) has reached the desired incineration temperature. Specifically, once the automated partition door (300) is opened, the sanitary waste from the compartment of the loading bin wheel (201) which is aligned to the exhaust assembly (415) falls therethrough and travels via the air-vortex unit (408), to fall under gravity into the primary heater (401). The bin flap (207) is closed to restrict loading when the automated partition door (300) is open, and vice-a-versa. As the sanitary waste falls from the first chamber (200) into the second chamber (400) incineration initiates. The incineration process then proceeds one napkin at a time, with each napkin being dropped into the heater chamber and burned in approximately 80 seconds, followed by a 15-second interval to check for a free compartment and reopen the bin flap (207) if allowed. If one napkin from the loaded six, in this example, is incinerated, a compartment becomes vacant, allowing the system (1000) to accept one more napkin until the pre-defined loading capacity is exhausted. That is, if a compartment is available and the temperature is maintained, the system (1000) automatically re-enables napkin acceptance, enabling ongoing operation without delay. This intelligent automation sequence ensures efficient use of the heater energy curve, strict user safety (no manual access during active combustion), continuous readiness for loading while maintaining strict operational logic, and optimized burn scheduling for fast and safe disposal of multiple napkins per cycle.
The blower (413) continues operating throughout the burning/ incineration process to continuously supply air at the air flow rate of 2.9 to 3.1m3 per 80 sec. Specifically, the blower (413) directs the air flow through the air-vortex unit (408) causing cyclonic turbulence, and generating the central circulation zone/ vortex zone above the heater () thereby allowing smoke and flames generated during the combustion to combine with fresh air from the blower (413) leading to efficient combustion. This action ensures thorough combustion of smoke and gases, maintaining smokeless operation.
During incineration: The sanitary waste(s) emit moisture, VOCs, and complex hydrocarbons during combustion. The primary heater (401) rapidly vaporizes moisture while igniting polymers and organics, releasing evolved gases upward into the vortex zone. The air-vortex unit (408) functions as an in-chamber emission control system, located just above the primary heater (401), and is designed to: sustain high-velocity swirling flow (Re > 4000), create turbulent mixing between radiative heat, flame, and combustion gases, extend residence time of volatile compounds, enabling secondary thermal oxidation before exhaust. This is crucial for handling odor-causing compounds and partially combusted hydrocarbons, especially from organic soiling. The bidirectional air movement ensures: ? Upper vortex: complete gas-phase combustion of evolved volatiles, and ? Lower swirl zone: supports solid-state burn, enhances drying, and ensures continuous oxygen feed.
Therefore, this optimized combustion and treatment method ensures CO, VOCs, and PM undergo complete oxidation within the single chamber, measured emissions show 0 PPM SO2, NOx, CO and 20.9% O2—well below CPCB norms, No HEPA, ceramic, or chemical scrubbers are required—eliminating maintenance overhead. Thus, the system (1000) and the method (2000) efficiently treat complex mixed-material sanitary waste in a compact, filter less, and fully compliant incinerator design.
Emission output meets CPCB norms with measured values far below permissible limits (e.g., SO2, NOx, CO = 0 PPM; O2 = 20.9%), as summarized in table below:
Parameter / Guideline System of present invention Measured CPCB Requirement
Sulphur Dioxide (SO2) 0 PPM = 50 mg/Nm³
Nitrogen Oxides (NOx) 0 PPM 400 mg/Nm³ (corrected limit)
Carbon Monoxide (CO) 0 PPM = 100 mg/Nm³
Oxygen in Flue Gas (O2) 20.9% = 6%
Visible Smoke None Absent / Opacity < 20%
Chamber Temperature 800–900°C = 800°C (primary chamber)
Plastic Combustion Control Controlled via air logic Only allowed >800°C with sufficient residence time
Odor-Free Operation No odor observed post-burn Strongly advised for indoor use
Ash Quality Fine, grey, non-clumpy Complete combustion indicator
Dioxin/Furan Compliance No PVC; complete combustion Testing not required if no PVC & efficient burn
Scrubber/Filter-Free Design Not required due to air vortex Maintenance-free systems preferred (i.e., no need for scrubber/filter replacement)
Residence
Time of Gases Approx. 2 seconds (vortex retention) = 2 seconds recommended

Post-incineration: Thereafter, post incineration cycle, emissions in form of cleaner air exits via exhaust outlet (418) pipe of the exhaust assembly (415) into the environment, whereas a small fraction of ash generated during combustion intermittently settles down to collect within the ash tray (500). (Steps 2090, 3000).
Thereafter, once one incineration cycle is completed, the method (2000) includes repeating the (steps 2070, 2080) and subsequent steps, such that yet another compartment is unloaded for incineration, making space for new loading onto the loading bin wheel (201), since the unloaded compartment now becomes vacant to accept new loading thereon. The loading is resumed only when the automated partition door (300) closes again, and loading continues even when the incineration in the second chamber (400) is ongoing. Thus, this step repeats in a continuous loop/ mode. Each time a new compartment that is aligned with the exhaust assembly (415) gets unloaded as the automated partition door (300) opens, and makes spaces for yet another loading from the bin flap (207). This operates continuously. (steps 3010, 3020).
Incineration time: facilitates complete combustion of the sanitary waste in short span of time, for example, in approximately 3-5 minutes (for full 6-napkin cycle). More specifically, the time required for incineration of one compartment is 80 sec., i.e. one compartment unloads per incineration cycle which is of 80 sec., followed by a 15 sec interval, before the next compartment is unloaded for another incineration cycle of 80 sec, and so on and so forth.
Dual-mode operation: The method (2000) includes a feeding mechanism that operates in dual-mode- batch-wise (stationary bin) and continuous (loading bin wheel with compartments). Particularly, the method (2000) operates in continuous mode (continuous processing/feeding) without any manual intervention being facilitated by the controller, as is explained in the method (2000) section above. However, in another example embodiment of the present disclosure, the method (2000) may also operate in batch wise processing mode- in which case the loading assembly consists of a stationary loading bin (201a), instead of rotating loading bin wheel (201). The user can load the sanitary waste(s) into the stationary loading bin (201a) until it is full of capacity, pursuant to which the method (2000) follows the same operation steps (2020 to 3020), for incineration of complete batch (entire loaded quantity, all waste present in the stationary bin) that has been loaded into the stationary loading bin (201a). That is during unloading, the stationary loading bin (201a) is entirely emptied of the sanitary waste(s) contained therein (all waste present is unloaded together) per incineration cycle and the automated partition door (300) is closed thereafter to initiate the incineration, before resuming loading of another batch of the sanitary waste(s).

Experimental/ testing data
The inventors of the present invention have carried out extensive comparative experimentation to support the claims that the system (1000) of the present disclosure facilitates in minimal to zero emissions during disposal of the sanitary waste(s). Testing was carried out by Horizon services Analytical laboratory, Pune. Following were the results that were obtained during comparative study of gas emissions with and without air-vortex treatment of the present invention:
• Sanitary waste incineration performed- using the system (1000) of present disclosure (i.e. alternatively referred to as ‘Smart Kojin mechanism’ in the testing report)

• Sanitary waste incineration performed- without using the system (1000) of present disclosure

Inference: It is thus evident from the test reports that the system (1000) of the present disclosure facilitates in emission-free, eco-friendly disposal of sanitary waste(s) as compared to conventional incineration-based sanitary waste disposal system/ methods. It is pertinent to note that the present invention offers a unique combination of sensor-based automation, cyclonic vortex combustion, and verified low-emission performance.

Some of the key characterizing features of present invention are summarized below:
• Integrated Cyclonic Vortex Combustion Zone: Promotes complete in-chamber oxidation of evolved gases without requiring filters or secondary scrubbers—achieving near-zero emissions. Re-combustion of flue-gases due to the cyclonic turbulence above the primary heater (401) which enhances flame stability and air-flame-flue gases interaction, leading to smokeless output (or emission-free disposal).
• Fully Automated Loading and Burning Logic: The loading wheel bin mechanism, combined with smart sensors and logic, enables contactless, safe, and sequential processing of napkins with user-independent triggering.
• Rapid and Efficient Cycle: Processes one napkin in just 80 seconds, with support for continuous batch operation up to six napkins—significantly faster than all prior technologies.
• Validated Emission Output: Independent analyzer results confirm SO2, NOx, and CO levels at 0 PPM, and O2 at 20.9%, which ensures indoor environmental safety, complying with and exceeding CPCB norms for decentralized incinerators.
• Compact, User-Safe Design: Dual thermocouple protection- one for monitoring the heater temperature and another for the machine body, overheat shutdown (automatically initiates a shut-off if the outer body temperature exceeds 50°C), sealed ash collection, and insulated housing ensure user safety and maintenance-free operation, reliable with ease of operations. Synchronization of all logic functions and vortex combustion and verified minimum emission in a compact form that the system (1000) offers for decentralized use in particular, although not limiting thereto.
• Buffer/ holding capacity: features a buffer/holding system that can store up to, for example, 6 napkins at once, each in a separate compartment (in event loading bin wheel (201) has capacity of 6 compartments). In an embodiment, the no. of compartments configured on the loading bin wheel (201) can be increased as per requirement to increase the holding capacity. However, it is pertinent to note there that, the system (1000) and the method (2000) processes one napkin at a time, with each incineration cycle taking 80 seconds after reaching the set incineration temperature (time is one napkin per 80-second incineration cycle). The holding capacity is primarily for user convenience, allowing users to load multiple napkins at once without having to wait between cycles.
Therefore, the system (1000) is fully automated, emission-compliant sanitary waste incinerator developed for, not limiting to, decentralized use such as for example, in schools, hostels, public washrooms, hospitals, rural setups, decentralized waste zones, healthcare environments and like. The system (1000) is a fully automatic, touch-free sanitary napkin incinerator equipped with high-precision sensors, integrated emission treatment, and a compact thermal chamber. The system (1000) ensures complete, clean combustion with real-time safety and performance monitoring. The present invention provides hygienic, fast, and safe disposal of sanitary napkins with touchless operation. The present invention is designed to be a single-chamber combustion architecture with an integrated air-vortex unit (408), functioning as an emission treatment system, and uses advanced turbulent air mixing and thermally synchronized combustion dynamics to achieve efficient gas-phase treatment—without external filters or secondary scrubbers for emission treatment.
The foregoing objects of the invention are accomplished, and the problems and shortcomings associated with prior art solutions and approaches are overcome by the proposed invention described in the present embodiment. The embodiments described herein above are non-limiting. The foregoing descriptive matter is to be interpreted merely as an illustration of the concept of the present disclosure and it is in no way to be construed as a limitation. Description of terminologies, concepts and processes known to persons acquainted with technology has been avoided to preclude beclouding of the afore-stated embodiments.

TECHNICAL ADVANTAGES AND ECONOMIC SIGNIFICANCE
The technical advantages and economic significance of the system (1000) and the method (2000) of the present disclosure include but are not limited to:
• User-Friendly: Fully automatic operation eliminates the need for manual intervention, fast and touch-less operation, compact and allows hands-free loading;
• Efficient Burning: Single-combustion chamber design and high temperatures ensure complete napkin incineration, minimizes energy loss;
• Environmental Safety/ Emission free operation: Tangential vortex airflow (2.9–3.1 m³/80 sec), and built-in vortex cyclone treatment ensures thorough combustion with minimal oxygen excess. Thus, minimal emissions- SO2: 0 PPM, NOX: 0 PPM, O2: 20.9%, CO2: 0%, CO: 0 PPM, no visible smoke, and efficient waste treatment without use of secondary scrubbers;
• Reliability and safety: Designed for consistent and reliable performance in sanitary napkin disposal, fully automatic since sensor module detect the presence of the sanitary napkin and initiate the incineration process automatically, requiring zero thinking and zero touch from the user;
