Comment on The Delusion of Advanced Plastics Recycling

There are alternatives to pyrolysis that are slowly coming online. They have their drawbacks – it’s certainly easier to chuck a bunch of mixed plastic into a reactor and heat it up until something happens – but they’re real.
I worked on one of them for a few years. It’s pretty cool! They’re currently building a pilot plant to demonstrate the technology at scale.

Doesn’t matter if the plastics never make it to the recycling center. Only around 5% of plastics in the US get recycled. Sometimes that’s because it’s cheaper to not recycle or because the particular plastic is non-recyclable, but most of the time it’s because it just gets thrown out with the rest of the garbage.
Sorting and separating materials en masse is by far the most difficult part of the process.

I don’t think articles like this help that situation. “Plastic isn’t actually recyclable” is a pretty dangerous mind virus that’s basically already running rampant.
Pyrolysis isn’t perfect. But it is absolutely better than throwing plastic in a landfill, and can handle otherwise impossible-to-recycle mixed feedstocks.
The process I worked on recycled PET while leaving the other materials in the mix untouched, ready to go through a different specialized process. That was kind of the whole point of it. Those sorts of technologies are harder in the sense that the tech is more sophisticated, but realistically doesn’t cost more to run once you have it going. The future isn’t all doom and gloom. That’s why I hate these “don’t bother recycling” articles.
