Mutant Enzyme Could Vastly Improve Recycling of Plastic Bottles

sciencehabit writes: Recycling isn't as guilt-free as it seems. Only about 30% of the plastic that goes into soda bottles gets turned into new plastic, and it often ends up as a lower strength version. Now, researchers report they've engineered an enzyme that can convert 90% of that same plastic back to its pristine starting materials. Work is underway to scale up the technology and open a demonstration plant next year. The researchers generated hundreds of mutant enzymes changing amino acids as they went. They then mass produced the mutants in bacteria and screened them to find efficient breakers of plastic bonds. After repeating this process for several rounds, they isolated a mutant enzyme that's 10,000 times more efficient at breaking down an important bond that allows plastic to be recycled.

The team is currently building a demonstration plant that is expected to recycle hundreds of tons of plastic per year. The enzyme can't recycle other major types of plastics, such as polyethylene and polystyrene, which have bonds between building blocks that are harder to break. But if successful, it could make it help society deal with one of the most challenging plastic problems we face.
John McGeehan, who directs the center for enzyme innovation at the University of Portsmouth, also tells Science that now recycling companies typically melt plastics together to make carpets or other low-grade plastic fibers that will eventually end up in a landfill or get incinerated.
"It's not really recycling at all."
