Researchers have developed a novel type of 'living plastic' that utilizes engineered bacteria to completely degrade within six days without producing microplastics.This innovation addresses the persistent issue of single-use plastic waste, which typically remains in the environment for decades.The material, based on polycaprolactone, incorporates dormant Bacillus subtilis spores that activate when exposed to nutrient broth at 122°F (50°C).Two sequential enzymes produced by the bacteria break down the polymer into its monomer components, preventing microplastic formation.A wearable device prototype demonstrated the material's functionality and biodegradability.Scientists aim to expand this technology to other plastics and develop methods for activation in water environments.The study highlights a potential paradigm shift in plastic design, integrating microbial degradation directly into the material's lifecycle.

This approach could revolutionize disposable products by eliminating long-term environmental contamination while maintaining necessary durability during use.
