Even worse, with the possible exception of the Sun Chips bag, corn plastic generally will not break down in home compost, even under ideal conditions -- it's only compostable in "industrial-scale" composting systems. So for those of you who live in San Francisco, which actually has municipal composting, that's all well and good, I guess. But for the rest of us, this stuff is still plain, old [genetically engineered] garbage.
But now researchers in the UK may have just fixed all that:
Scientists at Imperial College London are working on bioplastic packaging - made from trees and grass - that can break down in home composting bins.Very cool. Keep an eye on this stuff. It could really be the packaging of the future.
The polymer developed by the scientists is made from sugars that come from the breakdown of fast-growing trees and grasses, or agricultural and food waste.
The scientists from the Engineering and Physical Sciences Research Council purposely focused on non-food crops - many common bioplastics come from corn or sugar cane waste - and using low-energy and low-water processes.
