This 'living plastic' activates and self-destructs on command

Phys · · 466 words · By American Chemical Society

Researchers have developed 'living plastics' by embedding engineered Bacillus subtilis spores into polycaprolactone polymers. These microbes, when activated by a nutrient broth at specific temperatures, cooperate to fully degrade the plastic into monomers within days without producing microplastics.
