New recyclable protein textiles could cut microplastic pollution and lower clothing waste
Engineers at Washington University in St. Louis have developed a new type of recyclable protein textile aimed at reducing microplastic pollution and clothing waste. These protein-based materials can be recycled multiple times without losing their strength, and any microparticles released during washing are biodegradable. This innovation could significantly improve sustainability in the textile industry, which currently struggles with high waste and pollution levels.
- ▪The textile industry generates a large amount of waste, with only about 12% of fiber materials being recycled.
- ▪Synthetic fibers shed microplastics during wash cycles, contributing to ocean pollution.
- ▪The new protein-based materials can be recycled using a formic acid solution, allowing for multiple reuse cycles.
