Compostable plastic hard to compost

An article in “Nature Index” says that biodegradable and compostable plastic is not the panacea that many think. Kevin O’Connor of University College Dublin says “People think that biodegradability gives us a licence to throw away, it doesn’t.”

During recent trials O’Connor says that compostable plastic needed a temperature of around 50C to decompose whereas most domestic composting gets to about 24C.

He went on to say “The slow biodegradation observed in marine and fresh water shows that we should not allow any type of plastic to be released into these ecosystems.”

The only answer is to stop using plastic and not keep searching for a universal alternative that allows us to continue as we do.
