Algenesis and UC San Diego develop biobased TPU

In San Diego, University of California San Diego and Algenesis have developed a new biobased thermoplastic urethane to help address pervasive microplastics in the environment.

In a study published recently in Scientific Reports, the team proved that tiny plastic particles from their new TPU rapidly biodegraded under home composting conditions. They discovered that even common soil microorganisms are capable of growing on the microplastics, and use them as their sole carbon source. Essentially, these bacteria turn the bioplastic into harmless nutrients and carbon dioxide.

“This work is a step towards reducing pollution by creating material from natural plant sources (instead of petroleum) and ensuring that these materials won’t leave lasting microplastic waste in the environment,” according to an Algenesis press release.
