Environmental impacts of post-consumer plastic wastes: Treatment technologies towards eco-sustainability and circular economy

The huge amounts of plastic production (millions of tons) are carried out all around world every year and EU is one of the biggest consumers of these products. In 2021, recycling rate of plastic wastes around 32.5% in the EU and the rest end up on their journey in landfills and oceans that lead to environmental pollution which is a crucial global concern. Thus, it is important to take necessary steps to control the use of such plastic and to sustainably dispose them. One of the solutions to the problem is to use a better alternative to plastics which doesn't degrade land, water or air nor affects living organisms. Circular economy is another answer to this problem, it would ensure prevention of post-consumer plastic waste from getting formed. In addition, sustainable disposal approaches for plastic waste such as pyrolysis, plasma gasification, photocatalytic degradation, and production of value-added products from polymer waste can be explored. These recycling methods has huge potential for research and studies and can play a crucial in eliminating post-consumer plastic waste. This review paper aims to discuss the environmental effects of post-consumer plastic wastes as well as the emerging approaches for the treatment of these environmental wastes towards eco-sustainability and circular economy.

Automated summary

Plastic pollution is a global concern, with the EU being one of the largest consumers of plastic products. Only around 32.5% of plastic waste in the EU is recycled, leading to environmental pollution in landfills and oceans. It is crucial to control the use of plastics and find sustainable disposal methods. Alternatives to plastics and the circular economy approach can help prevent the formation of post-consumer plastic waste. Research into recycling methods, such as pyrolysis and plasma gasification, is important in eliminating plastic waste.
