Good idea: cradle 2 cradle fashion https://phys.org/news/2026-05-recyclable-protein-textiles-microplastic-pollution.html Engineers from Washington University in St. Louis may have a solution to waste from the textile industry: protein-based materials, which are produced in bioreactors (think giant brewing tanks) using genetically engineered microbes. These materials can be readily recycled after use and remade into the same fibers over multiple cycles. In addition, any microparticles, if released from these fibers during washing, would be biodegradable. "We engineered recyclable protein fibers that dissolve in a formic acid solution within seconds, yet remain stable in water and strong after drying," said Zhang.
