What should we think about biodegradable, compostable, bioplastics? Well, apparently, bioplastic utensils (knives, forks and spoons) do not break down in some composting systems. And since most compostable plastics are made from genetically engineered corn they are not organic (ruining one’s "organic compost" label) and thus have a larger carbon footprint than you might think due to the pesticides and fertilizer used on GE corn monoculture farms. Where can I get my compostable organic bioplastic iced tea cup? Please hold the straw and lid.
