Plastic Eating Microbes Have Potential for PET
It sounds like a science-fiction movie, but scientists working in Japan working with a plastic-eating microbe created a mutant enzyme that breaks down PET. PET is widely used in millions of plastics bottles. By tweaking the enzyme while studying it, they enable it to start digesting the the plastic more quickly. This enzyme could break the PET components back into their original forms to be reused.
Microorganisms do the recycling and we benefit from using less oil in our plastic production. Sounds like a good idea for a futuristic world.
