The research team ground down samples of the algae-based plastic to form microparticles and tested its biodegradability in compost. Results showed that 97% of the microplastics had fully biodegraded within 200 days.
Further analysis revealed that the biodegradable plastic was being effectively broken down back to its starting materials, showcasing a promising solution for microplastic pollution.
The development of this algae-based biodegradable plastic marks a significant step towards combating microplastic pollution and creating a more sustainable future for plastic products.
