Our Patented Process of Multilayer Plastic Waste and Our Solution – Brief Case Study

We are extremely delighted to share that we have been granted a patent for the “Process of Recycling Post-Consumer Multilayer Plastic”.  This is the Brief Case Study about our Solution for multilayer plastic waste.

Solving Untouched Problem of Multilayer Plastic Waste

Distribution of plastic consumption

According to the CPCB/Central Pollution Control Board report 2019-2020, India recycles around 60% of plastic waste generated. 40% of Plastic consumption is flexible, mostly Multilayer Plastic Waste which is left uncollected and littered due to its low value.

Post-consumer multi-layered plastic waste Recycling Process


SHAKTI works with all generators of waste to implement best practices in waste management as stipulated by the Municipal Solid Waste Management and Handling Rules outlined by CPCB. SHAKTI is committed to providing holistic and scientific solutions to managing waste at the source, thereby creating zero waste communities. SHAKTI is functioning as an agency and offers the required services to the Manufacturers / Brand Owners, under the Plastic Waste Management Rules.

SHAKTI is having an excellent collection network on a “PAN INDIA” basis and manages to collect the plastic waste by making use of the services of Rag Pickers, Plastic Scrap Dealers, ULB(s), NGO(s), Collection Centers / Partners, SHAKTI collects and process more than 300 M.T. of Plastic Wastes per day, which they segregate quality-wise in soft plastics and hard plastics such as HDPE, LDPE, PP, Multilayer, Biodegradable, etc.

  1. Process of Segregation:
    Initially, the collected plastic wastes are required to be segregated thereby removing the piece of paper and clothes therefrom. As a next step, the same is being shredded in small pieces. With this process, the dust and metal particles will be removed from the same.
  2. Washing to clean dirt:
    After sorting and processing it in the shredding machine, the plastic waste needs to be washed properly so as to remove impurities such as oil, dirt, labels, adhesives, etc., from the same. This process would help a lot to enhance the quality of the finished product.
  3. Making Granules
    After washing, the plastic wastes are dried in a drier and thereafter loaded into different conveyor belts that run the plastic wastes through different shredders. These shredders tear up the plastic into small pellets, preparing them for recycling into other products. After this the plastic wastes are blended with some chemicals and additives to enhance the properties thereof and thereafter, these are being fed to a twin-screw extruder to process it. For information, the Twin-screw extruder process is the best system for mixing the waste where all materials are blended together in a proper way and thereafter process such materials by palletizing through a Palletizer to give the material a uniform shape and size.
