New catalyst could make mixed plastic waste recyclable in one chemical step
Ever wondered where your plastics end up? A PET bottle can be washed, shredded, melted and given a second life. But most everyday items-toys, mattresses, car seats-are made from different plastics that refuse to mix when melted, producing unusable, contaminated material. Sorting is difficult and expensive, so most mixed plastic waste ends up burned or buried, and the materials are lost for good.
The science section covers breakthroughs in medicine, physics, biology, and technology. We surface discoveries that expand what humanity can do, from new treatments reaching clinical trials to engineering feats that seemed impossible a decade ago. Every link goes to the original publisher so you can read the full study or press release yourself.
