| Abstract |
Plastics are one of the best innovations of twenty-first century serving the humanity in all sectors of life such as agriculture, packaging, automotive, construction and healthcare. With ever increasing demand and ease of processability, plastic production is increasing at a rapid pace thus piling up huge amount of waste in the environment. Lack of infrastructure for plastic waste management, poorly managed recycling facilities and technologies, in-efficient waste collection systems, wrong and unrestrained disposal practices and lack of awareness contributes towards making plastic waste management an open challenge and a threat to the global environment. Previously, the best suited available strategies for plastic waste management include incineration, landfilling, and recycling and reuse, but they were not considered sufficient to tackle the large volume of the problem. Due to lack of infrastructure and management about 80% of the globally produced plastic had not been recycled in any form. Furthermore, the high cost associated with the recycling regarding sorting and processing makes recycling economically least feasible and non-sustainable. The resource circularity of plastic waste includes depolymerization of the waste polymer at the end-of-life cycle into the monomers followed by bio-upcycling to another value-added product thus entering into another life cycle. Talking about the economic validity and feasibility of bio-upcycling technology of plastic waste to produce value-added products, bio-upcycling is considered as a promising strategy as it involves transformation of depolymerized monomers from any route, may it be chemical or biological transformation, into the value-added products using endogenous or engineered metabolic pathways of already existing biological systems. In this review, bio-upcycling of plastic waste as a solution to the current limitations of traditional plastic waste management practices was discussed. Moreover, the biotechnological routes for the upcycling of plastic wastes into value-added products and economic circularity of the polymers were also described. Furthermore, the opportunities and challenges for promoting the circularity of plastic waste were also discussed. |
