Comment on Researchers invent 100% biodegradable 'barley plastic'

made from modified starch that can completely decompose in nature—and do so within only two months
That’s what I wanted to know. This is a huge improvement over current products that, while still plant-based, aren’t really biodegradable because they have to be processed in an industrial composting facility. For products that need to be durable only in the short term (e.g. takeout containers), this will be great!

The question then becomes how well does this work in place of traditional plastics? Does it have the same strength and water resistance? It needs to hold up to moisture in order to be used for takeout. If food partially breaks it down, people will be ingesting it so toxicity is also a concern. It will be interesting to see where this goes. Even if it can only replace shopping bags, that will still be a huge improvement. So many bags blow away in the wind and I live in an area that made it illegal for cities to ban single use shopping bags.

Toxicity might also be a concern if you compost it by throwing it into nature. This is my big gripe with all these alternatives: Are they less harmful than (micro)plastic?
