Link It's not really that new, as it has been used in plastic shopping bags but this is the first wide scale adoption of it. It adds an extra step in the process of consumption as the containers need to be returned to the store so they can send it to a commercial composter. They also can't withstand heat so aren't suitable for hot foods or heating things up in the microwave. Oil is currently the source for plastic and anything that lessens our dependence on the stuff is a great thing. The article doesn't say but since Cargill is behind the scheme, I can only guess the stuff is made from gm corn. Also, given the drought in Europe this summer, the world has been unable to produce enough to feed itself for four years in a row. So, I would imagine the price of this stuff isn't all that stable. But it is a step in the right direction. Let's hope there is more of this in the future.
