The Future Looks Bright for Infinitely Recyclable Plastic

Apr 22, 2021  Plastics are ubiquitous, but they're not practical. Less than 10% are recycled, and the other ~8 billion tons are creating a pollution crisis. A Berkeley Lab team is determined to change that. A new analysis shows producing and recycling their game-changing new plastic could be easy and cheap enough to leave old plastics in the dust.

Plastic Recycling - BPF

Nearly all types of plastics can be recycled, however the extent to which they are recycled depends upon technical, economic and logistic factors. As a valuable and finite resource, the optimum recovery route for most plastic items at the ‘end-of-life’ is to be recycled, preferably back into a product that can then be recycled again and again and so on.
