Finding viable alternatives to traditional petroleum-based plastics and microplastics has never been more important. New research from scientists at UC San Diego and Algenesis shows that their plant-based polymers biodegrade — even at the microplastic level — in under seven months.
You’re making perfect the enemy of good.
Yes, re-usable cups are better than a commercially compostable cup. Use re-usable cups if at all possible. But like it or not some people just aren’t going to do that, and commercially compostable cups are a hell of a lot better than plastic. Even if they don’t get composted, and you send them to regular landfill, they are still a million times better than plastic.
Sending plastic to the landfill that doesn’t decompose anaerobically is essentially the same as sending regular plastic. Also, using shitty material that has a shorter shelf life also means it allows for planned obsolescence for items you wouldn’t have thought was possible. For instance that can allow companies to put best use by dates on a refrigerator, home insulation, soles on shoes etc. For single use items it would make it so stock would be thrown out if not consumed more frequently. We would end up sending even more plastic to the landfills.
