Have you ever wondered about huge rise of compostable tableware and containers from corn? I did. Majority of corn is Genetically Modified by now – thanks to the companies that are definitely not our environmental friends, making it bit questionable how it eco-friendly they really are. And then – how long do they take to actually decompose? Thank You Umbra Fisk for your article in www.grist.org clarifying a bit what really happens with that corn. 
I found out also, what I really wondered about: “yes, the cups are biodegradable, but only in commercial composting facilities or other composts that reach 150 degrees with 90 percent humidity”. We have quite large compost piles for our few acres of veggies but we don’t get that temperature at all. No corn forks go there! Read more at http://bit.ly/BQRSB
A tiny town of Kamikatsu, Japan decided few years ago to limit their waste. They started with separating all household waste into 34 different categories designated for recycling. They found it cheaper and more environmentally friendly than alternatives. Look at the picture of their bins!
