Flotation separation of waste plastics for recycling—A
Diminished physical properties resulting from polymer–polymer incompatibility, discoloration, and degradation, cause a relatively low price for such mixed plastics compared with virgin polymers. In this regard, selective separation of waste plastics is the weakest link in the plastic-recycling industry.
Plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful products. Since the vast majority of plastic is non-biodegradable, recycling is a part of global efforts to reduce plastic in the waste stream, especially the approximately 8 million tons of waste plastic that enters the Earth's ocean every year.
· Plastic recycling in India • Municipal solid waste in India contain 1-4 per cent by weight of plastic waste. • India’s rate of recycling of plastic waste is the highest (60%) in the world as compared to other countries (China 10%, Europe 7%, Japan 12%, South Africa 16%, USA 10%).
Source separation of waste is encouraged in many jurisdictions, both within Australia and . metal, plastic and glass. Most member states have already implemented source separation, with positive outcomes to their waste diversion goals. United States . of solid waste and to improve recycling through the collection of source separated waste.
Solvent-based separation and recycling of waste plastics
The challenge of the disposal of accumulated waste plastics and corresponding environmental issues have received widespread attention from the public and academicians (Rochman et al., 2013, Jambeck et al., 2015).Waste plastics can turn into the resources for new plastic products; thus, a cyclic economy can be achieved by coupling waste prevention with material recycling.
What is Plastic Recycling and How to Recycle Plastic
Plastic recycling refers to the process of recovering waste or scrap plastic and reprocessing it into useful product. Due to the fact that plastic is non-biodegradable, it is essential that it is recycled as part of the global efforts to reducing plastic and other solid waste in the environment.
Plastics recycling: challenges and opportunities
