"Scientists have engineered a mutant enzyme that converts 90 percent of plastic bottles back to pristine starting materials that can then be used to produce new high-quality bottles in just hours."

"Unfortunately, current PET recycling is inefficient. When plastics of different colors are melted down during the recycling process, a gray or black plastic starting material results that few companies want to purchase to package their products, explained Science Magazine. The process results in low-grade plastic fibers only good enough for clothing and carpets, reported The Guardian. These eventually end up in a landfill or incinerated, added Science Magazine."
"The mutant enzyme broke down 90% of 200 grams of PET in a small reactor in just 10 hours. Different colors didn't matter because the enzyme can ignore dyes and other plastics in the molten mix. The researchers were able to use the resultant chemical building blocks to produce new PET and food-grade plastic bottles that were just as strong as those made from virgin plastics, reported Science Magazine."
As someone who recycles religiously this is excellent news and a breakthru that has been long needed.
Mutant Enzyme Recycles Plastic in Hours, Could Revolutionize Recycling Industry - EcoWatch
Scientists have engineered a mutant enzyme that converts 90 percent of plastic bottles back to pristine starting materials that can then be used to produce new high-quality bottles in just hours. The discovery could revolutionize the recycling industry, which saves about 30 percent of PET...
