Polyurethane is everywhere. From foam cushions and adhesives, to coatings and synthetic fibers, this versatile polymer is a significant presence in our daily lives. But there's a catch; while uses of polyurethane plastics offer many advantages, its non-biodegradable nature means it can stick around in the environment for a long time, contributing to the global microplastic pollution crisis that damages our ecosystems and our health.
However, a new study from a U.S. Department of Energy (DOE) Bioenergy Technologies Office (BETO) funded startup, Algenesis Corporation and the University of California San Diego has demonstrated the ability to formulate high-quality polyurethane products that generate no persistent microplastics. By utilizing some clever chemistry and sourcing oil from algae instead of petroleum, they can produce polyurethane plastics, including waterproof fabrics and cell phone cases, that biodegrade naturally in the environment.
The promise of high-quality yet biodegradable polyurethane plastics offers hope in the fight against microplastic pollution. By working with nature rather than against it, we can create a more sustainable future where our materials leave a positive impact on the planet and do not compromise our health.
