More than 80% of plastic waste generated today ends up in landfills. As per the ISO standards, when plastic can not be recycled physically (using processes like remoulding,) plastic should be recycled chemically by breaking it down into basic hydrocarbon fuels. apc‘s sustainable and cost effective technology converts plastic waste into fuels & petrochemicals. apc provides the sustainable and start-to-end plastic waste disposal services & solutions to help your organisation meet EPR (Extended Producers Responsibility) & environmental compliance goals of plastic disposal.
Plastic waste can be broadly classified into ‘physically recyclable’ and ‘chemically recyclable’ plastic waste. Given below are the differences between physical & chemical recycling of plastic waste:
|What type of plastics can be suitable for this method of recycling?
||– 80% of plastic waste generated globally is not suitable raw material for physical recycling. This includes of the post consumer packaging plastic waste, paper recycling plastic waste, post consumer laminate waste, end-of-life plastic waste, etc.– Only segregated plastic waste like HDPE, LDPE, PP, LLDPE, etc is suitable raw material for physical recycling.
||– All types of plastic waste are suitable as raw materials for chemical recycling, including of the post consumer packaging plastic waste, paper recycling plastic waste, post consumer laminate waste, end-of-life plastic waste etc.
|How the plastic waste is recycled using this method?
||Plastic is melted using temperatures up to 200 to 250 degree Celsius and filtered through a mesh to separate impurities.Then plastic is cooled down and converted into granules. These granules are used for manufacturing new plastic materials.
||– Pyrolysis: Plastic waste is subjected to temperatures of up to 500 degree Celsius in absence of oxygen. at this temperature the large plastic molecule breaks down into smaller molecules of diesel and base oil. after fractional distillation which oil is used for manufacturing lubricants and diesel is used as a fuel
– Hydrolysis: Plastic waste is subjected to temperatures of up to 200 degree Celsius in presence of chemical reagents. This results into chemical breakdown of plastic molecules. End products of hydrolysis is monomers and other petrochemicals.
