Recently I ran across these styrofoam cups which claim to be 370% more biodegradable than the average cup. I had to question, first why a disposable cup was necessary and second how could these cups be so much better. The website claims many positive environmental aspects www.dart.biz. Much of the information at this site was interesting, but all seemed quite bias. So perhaps now you will switch to the Dart brand cups and "help" the environment.
