The role of paradigms and technical strategies for implementation of the circular economy in the polymer and composite recycling industries

The circular economy (CE) is facing a problem of industrial implementation. The models are proposed for natural types of polymers and CE. The current work reports the technical strategies and paradigms for sustainable close-loop manufacturing. The post-consumer cotton polymer is used for optimization of functions like cost analysis, material evaluation, recycling technique selection, and quality control. The presentation of the results is advanced by break-even analysis, mechanical testing, tribological investigations, and polymer surface evaluations to select a reasonable processing technique. The current experimental and theoretical approaches could be used functionally for the adaption of the circular economy in polymer industries. The article also highlights the possible procedure for sustainable production of polymer products from natural and artificial wastes. (c) 2022 Kingfa Scientific and Technological Co. Ltd.
