The present invention relates to the separation of multi layered plastics, medicine strips and tetra packs and making of granules by utilizing different layers of plastics and specific fillers which can be used in making tiles, pallets or other products. Disposal of multilayered plastic waste and other two layered plastics and plastics from tetra packs is a bigger problem than conventional polyethylene bags because it is non-biodegradable and it mainly consists of different layers of low-density polyethylene (LDPE), polypropylene (PP), polyethylene terephthalate (PET) and metallized aluminum coatings and aluminum present along with PVC in pharmaceutical strips. Burning of these waste plastic bags causes environmental pollution. More particularly the invention relates to designing of granules and products by in-situ incorporating various filers in shredded multilayered waste plastic by separating the different layers of plastic and then making granules using a specific compatibilizer and then designing various products at a specific temperature and taking care of various issues like mechanical strength, flame retardancy, water permeability, UV- protection from sunlight and antistatic response which is the novelty of the invention.
3. Background of Invention
Plastics are widely used in packaging industry as it has basic properties such as light in weight, nontoxic, good barrier properties, resistant to chemicals, sterilizable, processability, transparent, do not corrode in humidity and do not promote any bacterial growth. For decades plastics have driven innovation in packaging design. From tamper resistant medicine packaging to the dual compartment package for hair dye, plastic helps drive innovation and is a leading material in creating effective packaging solutions for a variety of needs.

If there is one type of municipal solid waste that has become ubiquitous in India and most developing countries, and largely seen along the shores and waterways of many developed countries, it is multi layered plastic. Much of it is not recycled, and ends up in landfills or as litter on land, in waterways and the ocean. Plastic wastes generate formidable problems in their management as presently they are not biodegradable, are bulky and can resist incineration. Incineration in fact may not be possible due to production of noxious or toxic fumes. Plastic can remain under the ground for 500 years, which leads to the contamination of soil and thus pollutes the environment. Flexible packaging is most preferable option as packaging materials in various industries including Food, Beverage, Personal Care, Cosmetic, Healthcare, Retail Packaging, etc. To meet the respective specific and particular packaging demands use of lamination of plastics is a widely accepted practice in packaging industries. Such laminates use various plastic materials (PE, PP, PVC, PET, PA, EVOH, etc.), aluminum, paper as different layers. But the material isn't readily recyclable post-consumer.
Multi-layered plastics are made up of a layered composition of various types of plastics. This is a commonly used method because of the properties that the thus composed material acquires. Sometimes, the plastics material is also combined with non-plastics such as aluminum foil. Mixed plastics streams are generally separated on the basis of their density. Ensure that the density of the multi-layered plastics sufficiently deviates from that of the basic plastics types that are being recycled.
Moreover, manufacturers say that they cannot do without MLP. "Indian supply chain works in areas with sub-zero mercury levels as well in regions where temperatures reach 50°C. The humidity too is sometimes 100 per cent. Moisture and gas transmission rates through packaging materials go up with increase in temperature and humidity, but MLP can survive all that," says an official with the Central Public Health and Environmental Engineering Organization, on condition of anonymity. "An alternative material to match the performance of MLP is not yet available. These MLP waste packets are dumped in 250 sites across 15 cities

in India and found that 53 per cent of plastic waste in the cities was MLP. "Due to low source segregation and lack of continuous supply of MLP to the industries, it is not recycled," says Pratibha Sharma, Indian Coordinator-GAIA. In 2016, the government passed the Plastic Waste Management Rules that mandated phasing out "non-recyclable multi layered plastic" in two years. But on March 27, 2018, it amended them and "non-recyclable multi layered plastic" was substituted with "multi-layered plastic which is non-recyclable or non-energy recoverable or with no alternate use". This gave producers an escape route by claiming that the packaging material, if not recycled, can be put to some other use. MLP manufacturers used this loophole to continue to use the material. The 2016 rules also mandated companies to practice EPR and collect MLP that they have used to package their products. But they did not mandate a minimum percentage of the waste they must retrieve.
There has been a significant number of collaborations in this area. Various organizations are funding this technology, which implies technology commercialization.
Japanese electrical engineering company Yokogawa Electric has signed an investment and partnership agreement with Jeplan, a polyester-material recycling company with an innovative chemical recycling technology. According to Yokogawa, the polyester resin produced using Jeplan's BRING Technology has a quality equal to the conventional petroleum-based polyester resin.
Neste Oyj, an oil refining and marketing company located in Finland, and Mirova, a key player in sustainable finance, combinedly invested EUR 10 million in Recycling Technologies, a British plastic recycling technology provider for the acceleration and development of chemical recycling. Neste has also partnered with companies such as Ravago and Remondis, and has set a target to reach an annual capacity for processing over two thousand tons of waste plastic. It has a partnership with ReNew ELP and Australian technology developer Licella on a

project to use mixed waste plastics as a raw material for fuels, chemicals, and new plastics.
Norwegian firm Grant Punkt Norge has partnered with plastic-to-fuel specialist Quantafuel. Grant Punkt Norge will supply up to ten thousand tons of post-consumer plastic packaging to Quantafuel's new facility in Skive, Denmark, and the new plastic developed using chemical recycling is being supplied to BASF. Norwegian recycling company GemiNor is also participating in the project for developing a sorting line that is specifically tailored for Quantafuel's needs.

Application ID: 400/MUM/2009 - The Novel Process of Recycling Plastic Packaging Waste: (Vaishnav Hetal Kanji, Vaishnav Kanji Dungar)

The present invention relates to the novel process for recycling non-recyclable multilayer film plastic packaging waste into a recyclable composite material. The said recycling process does not require separation of multilayer film of plastic; therefore, the recycling process is economic and time savvy. Further to this, the said recycling process does not employ use of any chemical or binder or solvents. This composite material with the help of extrusion moulding, injection moulding or compression moulding can be used for making various articles, profiles and sheets so as to provide different applications. To obtain desired properties and applications, various binders, fillers, plasticizers, colour pigments, virgin plastic granules like PP, LDPE, HOPE etc. can be added to this composite material. The multilayered plastic materials are difficult to separate due to the physical forces acting on the constituent particles. The physical forces are especially great when multilayer plastics are co-extruded in a fashion that allows one layer to encapsulate the other plastic layer. Plastic packaging material made of multilayered film comprises more than one polymer like: Polypropylene (PP) + Biaxial Polypropylene (BOPP), Biaxial Polypropylene (BOPP) + Cast Polypropylene (CPP), Polyester + Low Density Polyethylene (LDPE), Polyester + Biaxial Polypropylene (BOPP), Polyester + CPP, Polyester + metalized Polyester + LDPE, Polyethylene terpthalate (PET) + metalized BOPP etc. These polymers can possibly recycled individually, however, multilayered plastic is difficult to recycle. The present invention involves recycling of multilayer film plastic packaging waste in composite material which has numerous applications resembling to plywood, wood-plastic composite and plastic lumber.
However, our innovation does not use adding virgin plastic granules and has different concept of recycling multi layered plastics.

US 2017/114205 - Process of recycling PET plastic waste
CARBIOS (Euronext Growth Paris: ALCRB), a company pioneering new, bio-industrial solutions to reinvent the lifecycle of plastic and textile polymers, announced today that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for an additional U.S. patent for CARBIOS' proprietary process of recycling PET plastic waste.
This patent application recognizes CARBIOS for its invention of a proprietary method of recycling complex plastics, including colored, opaque and multi-layer products containing a mix of polyethylene terephthalate (PET), and at least one additional component (e.g., polyolefins, vinyl polymers, rubber, cotton or nylon fibers, paper, aluminum, starch, wood, etc.). Many plastic products are made of multiple polymers or components that are mixed together or organized as layers. This makes them non-recyclable using current thermo-mechanical processes where mono-material waste is required. Traditional pretreatments, such as sorting,

reach a limit as they are not capable of separating PET from the other components. CARBIOS' technology overcomes these issues given its:
• Stable and reliable depolymerization of PET regardless of the composition of mixed PET plastic products or the presence of other components or polymers;
• Recovery of PET building blocks (PTA and MEG monomers) from complex plastics; and
• Separation and purification for a suitable use in any original application.
Recycling of multilayer packaging
• Multilayer packaging systems (sachets) hitherto not recyclable
• A recycling process is sought as an alternative to incineration or landfill
• CreaSolv® process is able to recycle waste composite materials
• Pilot scale trials already successful

6. Detailed Description of the invention:
Multilayer plastics can be formed by bonding, laminating or co-extruding numerous plastic materials. The multilayered plastic materials are difficult to separate due to the physical forces acting on the constituent particles. The physical forces are especially great when multilayer plastics are co-extruded in a fashion that allows one layer to encapsulate the other plastic layer.
Multilayered plastic is made from different layers of plastics like Polypropylene (PP), Copolymer of Poly propylene (PPCP), Low Density Polyethylene (LDPE), Linear low-density polyethylene (LLDPE), Polyethylene terpthalate (PET), aluminum coated polyester, aluminum coated PET, Al coated PP or Al coated PP. Multilayered plastics as such are difficult to recycle though there is a possibility of recycling individual plastics. The present invention involves recycling of multilayer film plastic packaging waste in making granules which has various applications in different areas.
Granules obtained from recycling multilayered plastic waste, are light, strong and corrosion-resistant, possesses good mechanical strength, and antistatic which

therefore can be used for different interior and exterior applications of construction.
The granules obtained from multi layered plastics can be injection moulded as well as compression moulded and can be easily extruded. Tiles, interlock tiles and sheets prepared from the recycled MLP granules can be used for different applications.
In accordance with the present invention the process for recycling of multilayered plastic packaging waste comprises the following steps:
(a) Multi layered plastic waste is assembled from landfills; (b) Multi layered plastic wastes is then washed with suitable alkali solution and thoroughly washed with water (c) Treating MLP plastic pouches with aqua regia containing nitric acid and HC1 or choline chloride/lactic acid solution (d) Again washing MLP plastic layers again with water and drying (e) agglomerating the plastic layers (f) making granules after mixing with compatibilizers and fillers (g) making the end product.
The process of recycling multilayered plastic waste is described in detail with its process steps as following.
a) Collecting of multi layered plastic waste: like chips packets, Nestle packets, haldiram namkeen packets, tetra packs and other MLP pouches which contain metallized aluminum and plastic layers.
b) Collected MLP plastic packets are then washed using a solution containing tap water mixed with NaOH, sodium bicarbonate and sodium lauryl sulphate. 1 Kg of MLP plastic wastes is washed using 5-10 Liters of water mixed with 0.5 to 1.0 N of NaOH, 0.5 to 1.0 N of sodium bicarbonate and 0.5 to 1.0 N of sodium lauryl sulphate

c) After cleaning MLP pouches with alkali solution and after through washing with water, MLP packets are treated with aqua regia containing a mixture of nitric acid and HC1 or choline chloride/lactic acid solution. Different layers of plastic are collected which are then again washed with tap water
d) Different layers of MLP sheets are then dried in hot air until MLP sheets are completely dry and free from moisture. Drying can also be done using Solar drying/heating.
e) Agglometering: Waste plastic sheets are put in agglometer and made into smaller shapers which can then be used for extrusion by adding other fillers like compatibilizers which play a specific role in blending LDPE, PP with PET layers.
f) Extrusion: The MLP above obtained in extruded along with other fillers by incorporating desired master pigment batch in order to obtain final granules which is cut with cutter into smaller granules of size 1-3 mm
h) Granules turning into desired tiles or pallets: Finally, the granules of MLP mixed with various fillers like fly ash, sand or red mud are reshaped into desired product using Injection Moulding or Extrusion Moulding or Compression Moulding etc., depending upon specific requirements.
In the whole process of recycling of multi layered plastics, no toxic fillers or organic solvents are employed. The process of recycling multi layered plastic packaging waste in a composite material is economical.

8. Examples:
The following examples are given to illustrate the process of the present invention and should not be construed to limit the scope of the present invention:
Example 1:
1 Kg of MLP was thoroughly washed with water to remove all the dust impurities. This was then stirred in a solution of 10 liters of solution containing 1.0 N caustic soda, 1.0 N of sodium bicarbonate and 1.0 M of sodium lauryl sulphate to remove all the grease or other impurities. Again, MLP was taken out and washed thoroughly with water to remove any amount of caustic soda. Washed MLP was then dipped in a reactor containing 5 liters of Aqua regia containing 1:3 ratio of nitric acid and hydrochloric acid at 90°C and stirred continuously for 30 minutes. Different layers of plastics and aluminum will then be separated and collected and again layers of plastic washed thoroughly to remove any amount of aqua regia. The plastic layers so obtained are agglomerated so that these can be then used for making granules. To these agglomerated plastics, compatibilizers (2 % of PP grafted maleic anhydride and 3 % of SEBS) and fillers (5 % of fly ash and 5 % of TPP) are mixed in high-speed mixer for V2 an hour, and then extruded in extruder so that desired granules can be obtained. These granules are then used for making desired end product.

This was then stirred in a solution of 10 liters of solution containing 1.0 N caustic soda, 1.0 N of sodium bicarbonate and 1.0 M of sodium lauryl sulphate to remove all the grease or other impurities. Again, MLP was taken out

and washed thoroughly with water to remove any amount of caustic soda. Washed MLP was then dipped in a reactor containing 5 liters of Aqua regia containing 1:3 ratio of nitric acid and hydrochloric acid at 90°C and stirred continuously for 30 minutes. Different layers of plastics and aluminum will then be separated and collected and again layers of plastic washed thoroughly to remove any amount of aqua regia. The plastic layers so obtained are agglomerated so that these can be then used for making granules. To these agglomerated plastics, compatibilizers (2 % of PP grafted maleic anhydride and 3 % of SEBS) and fillers (10 % of fly ash and 5 % of TPP) are mixed in high-speed mixer for V2 an hour, and then extruded in extruder so that desired granules can be obtained. These granules are then used for making desired end product.

Again, MLP was taken out and washed thoroughly with water to remove any amount of caustic soda. Washed MLP was then dipped in a reactor containing 5 liters of Aqua regia containing 1:3 ratio of nitric acid and hydrochloric acid at 90°C and stirred continuously for 30 minutes. Different layers of plastics and aluminum will then be separated and collected and again layers of plastic washed thoroughly to remove any amount of aqua regia. The plastic layers so obtained are agglomerated so that these can be then used for making granules. To these agglomerated plastics, compatibilizers (2 % of PP grafted maleic anhydride and 3 % of SEBS and 2 % of Glycidyl methacrylate) and fillers (5 % of fly ash and 5 % of TPP) are mixed in high-speed mixer for V2 an hour and then extruded in extruder so that desired granules can be obtained. These granules are then used for making desired end product.

Example 4:
1 Kg of MLP was thoroughly washed with water to remove all the dust
impurities. This was then stirred in a solution of 10 liters of solution containing
1.0 N caustic soda, 1.0 N of sodium bicarbonate and 1.0 M of sodium lauryl
sulphate to remove all the grease or other impurities. Again, MLP was taken out
and washed thoroughly with water to remove any amount of caustic soda.

9. Advantages:
• Multilayer plastics can be formed by bonding, laminating or co-extruding numerous plastic materials. The multilayered plastic materials are difficult to separate due to the physical forces acting on the constituent particles. The physical forces are especially great when multilayer plastics are co-extruded in a fashion that allows one layer to encapsulate the other plastic layer.

• Plastic packaging material made of multilayered film comprises more than one plastic like: Polypropylene (PP), Copolymer of Poly propylene (PPCP), Low Density Polyethylene (LDPE), Linear low-density polyethylene (LLDPE), Polyethylene terpthalate (PET), metalized aluminum polyester, aluminum coated PET, Al coated PP or Al coated PP. Multilayered plastics as such are difficult to recycle though there is a possibility of recycling individual plastics.
The present invention involves recycling of multilayer film plastic packaging waste in making granules which has various applications in different areas.
