Description:FIELD OF THE INVENTION

[0001] The present invention relates to a waste processing and biogas production device that is developed to manage various stages of waste handling, including sorting, treatment, and digestion, while optimizing conditions to ensure effective biogas production. More specifically, the device enhances the overall efficiency and sustainability of the waste-to-energy conversion process by ensuring that organic waste is processed effectively, contributing to energy generation, and minimizing environmental impact.

BACKGROUND OF THE INVENTION

[0002] Processing waste, especially organic waste, has always been a challenging task. Traditional methods usually involve sorting through waste by hand or using basic machines that separate recyclable materials. However, these methods are time-consuming and labour-intensive, often leading to inefficient waste management. For example, separating food waste from other materials or treating waste with harmful chemicals is both expensive and harmful to the environment. For producing biogas, the process requires careful handling of organic material, moisture levels, and contamination, which is difficult. In the past, small-scale waste-to-energy projects struggled with inconsistent results and required constant manual monitoring. This led to slow waste processing, ineffective biogas production, and increased energy costs. Also, these traditional methods highlighting the need for more effective waste treatment solutions.

[0003] Traditionally, mechanical sorting and shredding equipment were used. As these helped in reducing labour and speed up the separation of organic waste. However, these equipment’s still required significant manual intervention to ensure that waste was correctly categorized and processed. Biogas production was also in its infancy, with anaerobic digesters that break down organic matter into methane being large, inefficient, and requiring a lot of oversight. So, people also use large tanks for anaerobic digestion, which convert waste into methane for energy. These systems, while more efficient than their predecessors, but the machinery was expensive, space-consuming, and often required constant maintenance.

[0004] WO2024171328A1 discloses about an invention that includes a biogas production system is configured so as to be capable of producing a biogas using, as raw material, waste water-soluble coolants recovered from a machining device which performs cutting or grinding.

An organic waste treatment system having a biogas production device.

[0006] Conventionally, many devices have been developed that are capable of carrying out processing of waste and production of biogas. However, these devices are unable to detect waste characteristics such as moisture content and contamination levels, leading to improper waste sorting and treatment, which negatively impacts biogas production. Additionally, these existing devices also lack the ability to perform the microbial digestion process.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to optimize the waste sorting and treatment process, for ensuring that waste characteristics such as moisture content and contamination levels are accurately detected and appropriately managed for enhanced biogas production. In addition, the developed device also needs to facilitate the use of waste by incorporating organic materials that support the microbial digestion process, thereby leading to a more efficient and reliable biogas production from a variety of waste inputs.

[0019] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0020] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to a waste processing and biogas production device that facilitate the effective conversion of organic waste into biogas by ensuring proper management and treatment at every stage, which leads to maximized energy output and reduced environmental impact.

[0022] Referring to Figure 1, a perspective view of a waste processing and biogas production device is illustrated, comprising a housing 101 installed with a sliding horizontal tray 102, a pneumatic actuator 103 is installed beneath the tray 102, a touch enabled screen 104 is installed on the housing 101, an artificial intelligence-based imaging unit 105 installed on the housing 101, a sorter conveyor 106 provided inside the housing 101, a pair of flaps 107 connected to extendable links 108 are provided on the conveyor 106, a pair of chambers 109 provided with the conveyor 106, a motorized sprayer 110 is connected to a lime storage vessel 111, a motorized stirrer unit 112 mounted at an inner base of each chambers 109, a motorized dual-axis slider 113 provided on a ceiling portion of housing 101, a hydraulic pusher 114 attached with the slider 113, multiple containers 115 attached inside the housing 101, an extendable rod 116 is mounted at outer base of each container 115, a camera 117 installed inside the housing 101, a digester barrel 118 positioned within the housing 101, multiple cylinders 119 connected to the outlet of barrel 118, a motorized stirrer 120 is mounted at inner base of the barrel 118, a pair of storage units 121 provided inside the housing 101.

[0023] The device disclosed herein comprising a housing 101 that is equipped with a sliding horizontal tray 102, which is accessible by the user for the purpose of accommodating waste materials. The tray 102 is developed to facilitate the easy placement of waste onto its surface, ensuring a smooth and efficient process for the user.

[0024] The housing 101 is installed with a touch enabled screen 104 that allows user to provide touch input command regarding processing of the waste. The touch enabled screen 104 as mentioned herein is typically an LCD (Liquid Crystal Display) screen that presents output in a visible form. The screen 104 is equipped with touch-sensitive technique, allowing the user to interact directly with the screen 104 using their fingers. A touch controller IC (Integrated Circuit) is responsible for processing the analog signals generated when the user inputs details regarding processing of the waste. A touch controller is typically connected to the microcontroller through various interfaces which may include but are not limited to SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit).

[0025] The microcontroller analyzes the command of the user and subsequently actuates an artificial intelligence-based imaging unit 105 which is installed on the housing 101. The imaging unit 105 disclosed herein comprises of an image capturing arrangement including a set of lenses that captures multiple images of the tray 102 and the captured images are stored within memory of the imaging unit 105 in form of an optical data. The imaging unit 105 also comprises of the processor which processes the captured images.

[0026] This pre-processing involves tasks such as noise reduction, image stabilization, or color correction. The processed data is fed into AI protocols for analysis which utilizes machine learning techniques, such as deep learning neural networks, to extract meaningful information from the visual data which are processed by the microcontroller to detect placement of the waste over the tray 102.

[0027] As the placement of the waste over the tray 102 is determined, the microcontroller directs the tray 102 to translate the accommodated waste over a sorter conveyor 106 provided inside the housing 101. The tray 102 is coupled with a sliding unit, wherein the sliding unit consists of a pair of sliding rail fabricated with grooves in which the wheel of a slider is positioned that is further connected with a bi-directional motor via a shaft. The microcontroller actuates the bi-directional motor to rotate in clockwise and anti-clockwise direction that aids in rotation of shaft, wherein the shaft converts the electrical energy into rotational energy for allowing movement of the wheel to translate over the sliding rail by a firm grip on the grooves. The movement of the slider results in translation of the accommodated waste over the sorter conveyor 106 that is attached in continuation with the sliding tray 102.

[0028] In an embodiment of the present invention, a V-shaped pneumatic actuator 103 installed within the housing 101 to provide tilting movement to the tray 102. The actuator 103 gets pneumatically actuated, wherein the pneumatic arrangement of the actuator 103 comprises of a cylinder incorporated with an air piston and the air compressor, wherein the compressor controls discharging of compressed air into the cylinder via air valves which further leads to the extension/retraction of the piston. The piston is attached to the telescopic actuator 103, wherein the extension/retraction of the piston corresponds to the extension/retraction of the actuator 103. The actuated compressor allows extension of the actuator 103 to position the actuator 103 underneath the tray 102 in order to tilt the tray 102 and aid in translation of the accommodated waste over the sorter conveyor 106.

[0029] A moisture sensor is integrated with the conveyor 106 to detect the moisture content of the waste as they are transported. This sensor provides real-time data to ensure accurate monitoring of the waste's moisture level, which is critical for efficient sorting and treatment. The moisture readings from the sensor enable the microcontroller to distinguish between wet and dry waste, facilitating proper handling of the waste according to its moisture content.

[0030] The moisture sensor operates by emitting an electrical signal that interacts with the waste material. The sensor detects the dielectric constant of the material, which is influenced by the moisture content. A higher moisture level results in a higher dielectric constant, allowing the sensor to quantify the moisture present. The sensor then transmits this data to the microcontroller, triggering actions based on the detected moisture level.

[0031] The conveyor 106 includes flaps 107 connected to extendable links 108, which are coupled with a motorized ball-and-socket joint. The motorized ball-and-socket joint adjusts the flap 107 angles based on the moisture content detected in the waste. When the moisture sensor detects the waste as wet or dry, the flap 107 angles are adjusted accordingly, directing the waste into the appropriate chambers 109 along the conveyor 106. This adjustment ensures that wet and dry waste materials are efficiently separated and directed to their respective chambers 109 for further processing, optimizing the waste treatment process for biogas production.

[0032] The links 108 are pneumatically actuated, wherein the pneumatic arrangement of the links 108 comprises of a cylinder incorporated with an air piston and the air compressor, wherein the compressor controls discharging of compressed air into the cylinder via air valves which further leads to the extension/retraction of the piston. The piston is attached to the telescopic links 108, wherein the extension/retraction of the piston corresponds to the extension/retraction of the links 108. The actuated compressor allows extension of the links 108 to position the flaps 107 at an appropriate position.

[0033] The motorized ball and socket joint mentioned here consists of a ball-shaped element that fits into a socket, which provides rotational freedom in various directions. The ball is connected to a motor, typically a servo motor which provides the controlled movement. The flaps 107 is attached to the socket of the motorized ball and socket joint, the microcontroller sends precise instructions to the motor of the motorized ball and socket joint. The motor responds by adjusting the ball and socket joint and rotates the ball in the desired direction, and this motion is transferred to the socket that holds the flaps 107. As the ball and socket joint move, it provides the necessary movement to the flaps 107 in accordance with the detected dry/ wet waste, thereby directing the wet and dry waste into appropriate chambers 109 provided with the conveyor 106.

[0034] Simultaneously, the sorter conveyor 106 operates through a motorized drive arrangement, which moves the conveyor 106 along rollers or wheels positioned at both ends of the conveyor 106. These rollers or wheels support the belt and ensure its smooth movement while minimizing friction. The speed of the conveyor 106 is controlled by the motor, allowing for precise handling of materials. As the waste moves along the conveyor 106, integrated sensors measure the moisture content. Based on these measurements, the microcontroller directs the waste into appropriate chambers 109 for further processing. The wheels or rollers help maintain the continuous flow and alignment of the belt, contributing to efficient waste sorting and handling.

[0035] A multi-sensor array is strategically positioned within the chambers 109, the array comprising Near-Infrared (NIR), Infrared (IR), and Raman spectroscopy sensors. The array is configured to detect and differentiate acidic, fatty, or chemically contaminated materials present within the segregated wet and dry waste. The sensors function independently and in coordination to enable comprehensive identification of varied waste characteristics, whereby the resulting sensor data is communicated to a processor operatively linked to the microcontroller for further analysis.

[0036] The Near-Infrared (NIR) sensor operates by emitting near-infrared light onto the surface of the waste material. As the light interacts with the molecules in the sample, a portion is absorbed and the rest is reflected. The sensor captures the reflected light and converts it into a spectral signal. This signal is then processed to identify specific organic compounds, such as fatty acids or other hydrocarbons, based on their unique absorption patterns. The sensor relays this data to the microcontroller, enabling differentiation between various chemical compositions in the waste for targeted processing or treatment.

[0037] The Infrared (IR) sensor functions by emitting infrared radiation onto the surface of the waste material. As the waste absorbs the IR radiation, molecules within the material vibrate at characteristic frequencies. The sensor detects the resulting absorption spectrum, which is indicative of specific chemical bonds such as those found in acidic or organic compounds. This spectral data is processed in real-time to identify the presence of these compounds. The IR sensor then communicates the results to the microcontroller, which uses the information to classify the waste.

[0038] The Raman spectroscopy sensor works by directing a laser beam onto the waste material. When the laser light interacts with the molecules, most photons are elastically scattered, but a small portion is inelastically scattered (Raman scattering), resulting in a shift in the light’s wavelength. This shift corresponds to specific molecular vibrations and provides a unique molecular fingerprint. The sensor captures the scattered light and analyzes the Raman spectra to detect chemical contaminants and complex organic substances. This data is transmitted to the microcontroller, facilitating the classification of chemically contaminated waste for appropriate handling and treatment.

[0039] A motorized sprayer 110 is operatively connected to a lime storage vessel 111 through a collapsible pipe, the arrangement being configured to dispense lime into the designated chambers 109 for waste treatment. Upon activation by the microcontroller, the motorized sprayer 110 is actuated to deliver a measured quantity of lime through the pipe, thereby enabling the chemical neutralization of acidic or contaminated components present in the waste. The dispensing operation is executed in a controlled manner to ensure uniform distribution of lime within the chamber 109, thereby facilitating effective treatment of the waste material prior to subsequent processing stages.

[0040] Simultaneously, the microcontroller regulates the actuation of a motorized stirrer unit 112 which is mounted at an inner base of each chamber 109 and is configured to facilitate uniform and thorough mixing of the dispensed lime with the accommodated waste. Upon activation, the motor rotates the shaft of the stirrer unit 112, causing the attached paddles or blades to turn within the chamber 109. This motion agitates the contents, thoroughly mixing the lime with the waste. The continuous rotation breaks up any clumps and ensures the lime is evenly spread, promoting consistent chemical reaction across the entire waste volume. The microcontroller adjusts the speed and duration of the stirring based on sensor array feedback, thereby completing the mixing cycle once uniformity is achieved, ensuring the waste is properly conditioned for digestion and its pH is adjusted effectively.

[0041] A motorized dual-axis slider 113 is disposed along a ceiling portion of the housing 101 and is operatively controlled by the microcontroller. The slider 113 is configured to translate along two perpendicular axes and is mechanically coupled with a hydraulic pusher 114. The dual-axis motorized slider 113 consists of two axes of motion, typically arranged perpendicular to each other, allowing movement in both horizontal and vertical directions. The slider 113 is controlled by the microcontroller. At its core, the slider 113 consists of a motorized arrangement that drives the translation of the pusher 114 suspended from it. This arrangement may utilize stepper motors, servo motors, or other motor types, depending on the design requirements. The microcontroller sends signals to the slider 113, dictating the precise movements required for positioning the pusher 114 accurately.

[0042] The pusher 114 is powered by a hydraulic unit that consist of a hydraulic cylinder, hydraulic compressor, hydraulic valve and piston that work in collaboration for providing the required extension/retraction to the pusher 114. The microcontroller actuates the valve to allow passage of hydraulic fluid from the compressor within the cylinder, the hydraulic fluid further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the pusher 114 and due to applied pressure, the pusher 114 extends and similarly, the microcontroller retracts the pusher 114 by closing the valve resulting in retraction of the piston. The microcontroller regulates the extension/retraction of the pusher 114 in order to exert pressure on bulk portions of waste, resulting in fragmentation of the material, expanding the exposed area, and promoting enhanced microbial activity during the anaerobic decomposition cycle.

[0043] A plurality of containers 115 is secured within the housing 101, wherein each container 115 is designated for holding a specific category of waste, including but not limited to vegetable waste, grains, and fruit. An extendable rod 116 is operably affixed to the lower exterior portion of each container 115. The rod 116 is configured for elevating the corresponding container 115 toward the designated chamber 109 and subsequently initiating a tilting motion via a hinge joint, to enable the discharge of the contained materials into the chamber 109.

[0044] The rod 116 is pneumatically actuated, wherein the pneumatic arrangement of the rod 116 comprises of a cylinder incorporated with an air piston and the air compressor, wherein the compressor controls discharging of compressed air into the cylinder via air valves which further leads to the extension/retraction of the piston. The piston is attached to the telescopic rod 116, wherein the extension/retraction of the piston corresponds to the extension/retraction of the rod 116. The actuated compressor allows extension of the rod 116 to position the containers 115 in an appropriate position.

[0045] Synchronously, the microcontroller actuates the hinge joint configured in between the rod 116 and containers 115. The hinge joint mentioned above is preferably a motorized hinge joint that involves the use of an electric motor to control the movement of the hinge and the connected component. The hinge joint provides the pivot point around which the movement occurs. The motor is the core component responsible for generating the rotational motion. It converts the electrical energy into mechanical energy, producing the necessary torque that drives the hinge joint. As the motor rotates, the motorized hinge joint tilts container 115 to dispense materials into the chamber.

[0046] At the same time, animal waste, including but not limited to cow dung, is introduced into the chambers 109 for the purpose of enhancing microbial digestion efficiency. A pair of storage units 121 is provided within the housing 101, wherein one unit is designated for storing cow dung and the other for water. A motorized nozzle, connected with a hollow passage, is operatively configured to dispense controlled quantities of cow dung and water from their respective storage units 121 into the chambers 109.

[0047] Upon delivery, the materials are combined to form a slurry of predetermined composition. The slurry is subsequently subjected to mixing to ensure uniform distribution and to achieve an optimized moisture content, thereby facilitating improved anaerobic digestion performance and enhancing biogas production efficiency.

[0048] After the slurry of cow dung and water is dispensed into the chambers 109, the stirrer unit 112 is activated again to process the mixture. The stirrer moves to thoroughly blend fatty acid-containing waste with non-fatty acid-containing food waste. This grinding action ensures that the waste is uniformly combined, which is critical for the efficient operation of the anaerobic digestion process. By creating a homogeneous mixture, the process facilitates better microbial digestion, enhancing the overall breakdown of the waste and increasing the potential for biogas production. The continuous mixing promotes an optimal environment for microbial activity, contributing to effective waste treatment and energy generation.

[0049] During the mixing operation, maintaining an optimum temperature is crucial for efficient microbial digestion. A Peltier unit integrated with the chambers 109 regulates the temperature by transferring heat either away from or towards the chamber 109, ensuring that the internal temperature remains within the desired range. This temperature control fosters an ideal environment for microbial activity, promoting effective waste degradation. By ensuring the proper temperature, the Peltier unit supports the anaerobic digestion process, enhancing biogas production and preventing temperature-related disruptions that impede microbial functions or slow down digestion efficiency.

[0050] The Peltier unit consists of two semiconductor plates, known as Peltier plates, connected in series and sandwiched between two ceramic plates. When an electric current is applied to the Peltier unit, one side of the unit absorbs heat from its surroundings, while the other side releases heat, thereby regulate temperature and preserve the quality of waste by maintaining a low temperature, which results in slowing down decomposition and preventing excessive fermentation before processing.

[0051] An electronic nose is installed in each chamber 109 to detect Odors emitted by the waste materials within the chamber 109. The electronic nose operates by using an array of chemical sensors that respond to specific volatile organic compounds (VOCs) emitted by decomposing waste. Each sensor is sensitive to a different type of compound, and when the waste releases these compounds, the sensors detect their presence. The signals from the sensors are then processed by the microcontroller, which analyzes the concentration of the detected VOCs and provides data on the waste's condition. This enables real-time monitoring of odors emitted by the waste.

[0052] A camera 117 is installed within the housing 101, which is triggered to activate upon detection of a strong odor. The camera 117 is used to visually inspect the waste for signs of fungi, mold, or other contaminants that may be present. Upon detection of an odor, the camera 117 captures images or video footage of the waste material in question. The captured data is then processed to identify any visible contaminants, such as mold or fungal growth, ensuring that appropriate actions are taken to address contamination and maintain the quality of the waste processing process.

[0053] Thereafter the Peltier unit regulate temperature within the waste processing chambers 109. The Peltier unit provides controlled thermal management, ensuring that the waste material remains at an optimal temperature for the anaerobic digestion process. This thermal control is crucial for maintaining the desired conditions that facilitate microbial activity and enhance biogas production. Additionally, the Peltier unit deliver thermal treatment, such as pasteurization, which involves applying specific heat to eliminate harmful bacteria or pathogens in the waste. By maintaining precise temperature control, the Peltier unit ensures that the waste is treated safely and efficiently, minimizing health risks and promoting effective waste processing.

[0054] A digester barrel 118 is strategically positioned within the housing 101 and interconnected with the chambers 109 through hollow tubes. This barrel 118 is equipped with a first opening located on one side wall, which is fitted with an iris lid. The iris lid is operable to allow the transfer of waste material, in slurry form, into the barrel 118 for further processing. The design ensures controlled and efficient transfer of waste into the digester barrel 118, preventing spillage or contamination.

[0055] Further a motorized stirrer 120 is mounted at the inner base of the digester barrel 118 and is configured to rotate and mix the material inside the barrel 118. The stirrer 120 rotation ensures uniform mixing of the waste material, preventing the formation of clumps, which hinder the anaerobic digestion process. The continuous motion promotes the breakdown of organic material, improving the efficiency of the biogas production process by ensuring better microbial interaction with the waste.

[0056] The motorized stirrer 120, mounted at the inner base of the barrel 118, is powered by a motor connected to a rotating shaft. Upon activation, the motor drives the shaft, causing the stirrer 120 blades to rotate. As the blades rotate, they come into contact with the waste material within the barrel 118, causing the waste to be lifted, mixed, and redistributed. This continuous motion prevents the accumulation of solid clumps and ensures uniform exposure of the waste to the anaerobic environment, promoting faster degradation. The motor's speed and rotation direction are controlled to optimize mixing efficiency, enhancing biogas production.

[0057] Afterwards a second opening which is provided on the opposite top side wall of the barrel 118 is equipped with an iris diaphragm that regulate the release of produced biogas. Upon reaching a predefined duration, the iris diaphragm automatically opens, allowing the biogas to be transferred from the barrel 118 to multiple cylinders 119 connected to the outlet of the barrel 118 via a conduit. The conduit is further equipped with an iris unit, which is responsible for controlling the flow of the biogas into the cylinders 119. These cylinders 119 are specifically configured to store the generated biogas, ensuring safe containment and preventing unnecessary leakage.

[0058] The cylinders 119 used for storing the produced biogas are equipped with pressure control valves. These valves are designed to maintain the safe and optimal pressure levels within the cylinders 119 while the biogas is stored. The pressure control valves automatically regulate the internal pressure, ensuring that the pressure does not exceed predefined thresholds that pose a risk of rupture or leakage.

[0059] The pressure control valve continuously monitors the internal pressure within the cylinders 119 via a pressure sensor. When the pressure rises above a set threshold, the valve opens to release excess gas, maintaining a stable pressure within safe limits. Conversely, if the pressure drops below the desired level, the valve adjusts to maintain equilibrium, ensuring that the internal pressure remains within the specified range for safe and efficient biogas storage.

[0060] A sensing module is incorporated within the device, comprising Electrochemical Sensors, Infrared (IR) Sensors, and Photoionization Detectors (PID), each configured to detect a range of gases produced during the anaerobic digestion process. This includes methane, carbon dioxide, hydrogen sulphide, ammonia, and various trace gases. The module is designed to operate in real-time, continuously monitoring the presence and concentrations of these gases within the device. The collected data is then transmitted to the microcontroller, which processes the information and directs corrective actions as necessary, ensuring safe operation and efficient biogas production.

[0061] The electrochemical sensors detect specific gases by utilizing a chemical reaction. When a target gas, such as methane or hydrogen sulphide, enters the sensor's electrochemical cell, it undergoes a redox reaction, generating an electrical current proportional to the concentration of the gas. This current is measured by the sensor, providing a real-time reading of the gas concentration. The sensor is typically calibrated for the target gases like methane or hydrogen sulphide, ensuring accurate detection.

[0062] The Infrared (IR) sensors detect gases by measuring the absorption of infrared light at specific wavelengths. As gas molecules pass through the sensor, they absorb infrared radiation at particular wavelengths that correspond to the molecular composition of the gas. The sensor emits infrared light through the gas sample and detects the amount of light absorbed. This amount correlates directly to the concentration of the specific gas present, such as carbon dioxide. The sensor's readings are processed and communicated to the microcontroller, which utilizes this data to monitor and manage the anaerobic digestion process.

[0063] Further Photoionization Detectors (PID) work by utilizing ultraviolet (UV) light to ionize gas molecules. When the UV light is directed at a gas sample, the high-energy photons cause certain molecules to become ionized, creating charged particles (ions and electrons). The PID sensor detects the resulting electrical current from the ionized molecules, which is proportional to the concentration of the gas in question. PID sensors are particularly useful for detecting volatile organic compounds (VOCs) and other trace gases. The measured current is processed and transmitted to the microcontroller, aiding in the monitoring of gas concentrations in the anaerobic digestion process.

[0064] Moreover, a generator is associated with the device to power the electrical and electronically operated components, supplying the necessary voltage to these components. The generator works by converting mechanical energy, usually from an external fuel source, into electrical energy. This electrical power is then distributed to the components of the device, ensuring continuous operation. Given the size and power demands of such machines, the generator provides a steady and reliable power supply, eliminating the need for battery-based energy storage.

[0065] The present invention works best in the following manner, where the housing 101 as disclosed in the invention is installed with the sliding horizontal tray 102 that is accessed by the user for accommodating waste materials over the tray 102. The touch enabled screen 104 accessed by the user to give input commands regarding processing of the waste. The microcontroller linked with the screen 104 processes the input commands and activates the artificial intelligence-based imaging unit 105 to detect placement of the waste over the tray 102. Synchronously, the tray 102 translates the accommodated waste over the sorter conveyor 106. Then the moisture sensor detects moisture content in the waste. The conveyor 106 includes flaps 107 connected to extendable links 108 coupled with the motorized ball-and-socket joint that adjust flap 107 angles based detected dry/ wet waste, directing the wet and dry waste into appropriate chambers 109 provided with the conveyor 106. Thereafter the multi-sensor array detect presence of acidic, fatty, or chemically contaminated materials in the wet and dry waste(s). The motorized sprayer 110 dispenses lime into the chambers 109 to treat the waste. Simultaneously the motorized stirrer unit 112 facilitate thorough mixing of lime with the waste, ensuring the accurate and effective pH adjustment. The motorized dual-axis slider 113 translates the hydraulic pusher 114 attached with the slider 113 and align the pusher 114 with the chambers 109 to apply compressive force to large chunks of waste for breaking down the waste, increasing surface area, and facilitating more effective microbial degradation in anaerobic digestion process. Multiple containers 115 storing vegetable waste, grains, and fruit. The extendable rod 116 raises the container 115 toward the chamber 109 and to tilt the container 115 to dispense materials. Also, animal waste, such as cow dung, is introduced to the chambers 109 to enhance microbial digestion. The pair of storage units 121 stores cow dung and water, and the motorized nozzle dispenses water and cow dung into the chambers 109 to form the slurry, which is then mixed to adjust the moisture content for optimal digestion. And at the same time the stirrer unit 112 grind fatty acid-containing waste with non-fatty acid-containing food waste, facilitating the homogeneous mixture for subsequent biogas production.

[0066] In continuation, the Peltier unit regulate temperature and preserve the quality of waste by maintaining the low temperature. Afterwards the electronic nose detects odors emitted by the waste. The camera 117 identifies presence of fungi, mold, or other contaminants in waste. The heating unit provide thermal treatment, such as pasteurization, to eliminate harmful bacteria or pathogens, ensuring safe and efficient processing of waste. The digester barrel 118 includes the first opening on one side wall of barrel 118, equipped with the iris lid to allow transfer of waste material in slurry form into the barrel 118. The motorized stirrer 120 rotates and mix material inside the barrel 118, reducing clumping and accelerating the biogas production process. The second opening on opposite top side wall of barrel 118, equipped with the iris diaphragm that opens after the predefined duration to release produced biogas into multiple cylinders 119. The cylinders 119 are configured with pressure control valves to maintain safe pressure levels while storing the produced biogas. Further the sensing module configured to detect various gases produced during anaerobic digestion process, including methane, carbon dioxide, hydrogen sulfide, ammonia, and trace gases. Furthermore, the sensing module is interconnected with the microcontroller, that directs the detected gases to separate chambers 109 based on concentrations of each gas.
