If it's barely plastic, then what is it?

Probably fairly brittle

I did what you see there

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?

There are lots of biodegradable plastic alternatives now. I wish there were more government incentives to use them. Outlawing or taxing the hell out of single-use non biodegradable plastics in non-medical uses would help.

maybe we should robocall every Nestle employee every 5 minutes asking about it.

it may be helpful in some cases, but often plastic is so successful because it's not biodegradable. if insects, bacteria and fungi have a hard time eating through it, it's a container that can protect the contents from them. it's difficult to replace withpout losing that ability, especially when it is preferred to be transparent (as in see-through) as well

We already have "biodegradable" plastic made from corn starch. It's not truly biodegradable, I reserve the right to wait for more information about whether barley starch is any better.

Another great discovery that will curiously disappear within a year
