Recent Studies on Recycled PET Fibers: Production and Applications: a Review

Abstract

Increasing demand for non-biodegradable plastics undesirably leads to their accumulation and calls for an appropriate solution for this global crisis. Environmental impacts of PET waste have long been addressed; although some remedies have been proposed, their extensive use in the modern world use demands new studies and recycling techniques. It shows the inadequacy of previous solutions to eliminate this environmental problem. Therefore, researching this subject should not be considered an insignificant issue. Distinctively, this review article has a specific reliance on the use of recycled PET fibers in the production of high-consumption and value-added products that, in addition to considering environmental aspects, can also be attractive to the market. This article deals with recent studies in three product categories (concrete, nonwoven fabrics, yarns) made from recycled PET fibers and shows the high potential of PET fibers for the future industry.
