The problem is that even the large scale composting facilities don't want bioplastics either, and for good reason- they're difficult to break down fully and the little pieces can end up in the finished compost.

I wanted to give it another six months and take a peek, so when May comes around we'll see how it went through the winter months, and if the cold had a serious effect on the process. An aside: I was collecting the last of the leaves off my street yesterday to use for my next compost pile, and I decided to try a biodegradable garbage bag since I had some different…
