A team of engineers at the Massachusetts Institute of Technology (MIT) has engineered a recyclable yarn made from polyethylene, offering a scalable solution to the global challenge of textile waste. Detailed in ACS Materials Letters, the research was led by Svetlana Boriskina, a research scientist in MIT’s Department of Mechanical Engineering, alongside first author SeongHyeon Kim and co-authors Duo Xu, Volodymyr Korolovych, Domingo Flores-Hernandez, Kaniz Moriam, and Daniel Braconnier.
The MIT team demonstrated that garments crafted from the engineered yarn can be melted down at the end of their lifecycle and respun into fresh fiber or molded into solid plastic hardware, such as buttons and belt buckles.
