Multilayer Plastics: Challenges & Solutions

Multi Layered Plastic Packaging

Background Information
India generates 3.3 million metric tons of plastic waste per annum according to the Central Pollution Control Board (CPCB) report. Although there has been decades of work surrounding plastic pollution, it still is a major problem and continues to present challenges. Multi layered plastic waste is a huge contribution for this problem and this article will give a glimpse about MLP, its impact on the environment and what potential solutions we have to solve this problem.

Multi Layered Plastic
MLP stands for Multilayered plastic and according to the PWM 2016 Rules, is defined as any material used or to be used for packaging and having at least one layer of plastic as the main ingredients in combination with one or more layers of materials such as paper, paper board, polymeric materials, metalized layers, or aluminum foil, either in the form of a laminate or co-extruded structure. Basically MLP is any material that has at least one layer of plastic. MLP has several thin sheets of materials like aluminum, plastic, and paper that are laminated together and are difficult to separate.

Multilayer Plastics: Challenges & Solutions

Impact of MLP waste on Environment:
4O percent of global plastic waste is generated for packaging, which includes MLP used in food packaging. This is usually used once and discarded hence are considered as single use plastic. MLP is a preferred material in the food industry, as it protects the food products and hence giving it a longer shelf life. India has a diverse climate and the nature of MLP allows protection of food in climates like hot and humid. Hence, it is preferred on a large scale across India. Apart from this, it’s lightweight, available in different sizes from small packets to big packets, makes it available in small tea stalls to supermarkets. It is present everywhere and is easy to throw but difficult to collect. And eventually it ends up as litter, or in landfills or in waterways, and enters our food chain. The practical challenges in collection and segregation of  MLPs involve labour intensive work, space constraints for storage due to its voluminous nature etc. This makes recycling of MLP economically unviable and is mostly destined to end up in landfill. However few technological interventions have made it possible to manage this waste.

Potential Solutions for managing the MLP waste

  1. Energy recovery: Use of MLP in Cement factories as an alternate fuel or in Waste-to-energy (WTE) plants are considered as a solution in reducing the plastic waste. These technologies offer the solution to process the gigantic volumes of MLP on a regular basis.
  2. Granules into products: The recycled plastic granules from the MLP waste, can be used in the injection moulding applications such as flower-pots, wastebaskets, road dividers, low-cost furniture, park benches etc. The granules made from MLP are a benefit for manufacturers and producers as the MLP pellets, apart from being sustainable, are also cheaper than the virgin pellets. They not only contribute to a circular economy but also reduce the huge amount of MLP waste ending up in landfills and harming the environment.

Pyrolysis: Pyrolysis by definition means the thermal decomposition of materials at elevated temperatures in an inert atmosphere. It is a common technique used to convert plastic waste into energy. The liquid oil produced through this process can be used as an alternate fuel and helps in reducing the carbon footprint.

Benefits of MLP Recycling:

  • Considering the increasing amount of MLP waste, recycling is the best and sustainable solution for reducing the impact caused by MLP waste.
  • MLP recycling manages the highly polluting and littered plastic waste and contributes to the circular economy.
  • It ensures resource recovery plus is economically beneficial.
  • Also generates employment, and is paving the way for formalizing the recycling sector which includes stakeholders like ragpickers, recyclers, etc.
