@econads @renwillis @sinituulia "biodegradable plastics" and "bioplastics" aren't the same thing, the plastic bags that were a big deal in the UK 20 years ago were made of quite different materials from the compostable things now. If you put anything in a "biodegradable" bag in the attic, it's surrounded by a pile of tiny fragile flakes now. And if anything compost heaps preserve them.
