Day One: Put cup in vermicompost bin.

I do not really understand what these cups break down into. Micro pieces of plastic? Is bio-based plastic something I want in my worm bin? I thought plastic was a bad thing. Is it food or bedding?

"cups are made from a bio-based plastic (from plants like corn) that feels just like the real thing. However, unlike conventional cups made from petroleum-based plastic, our cups are compostable*."

"*Compostable in a commercial composting facility. Such facilities may not be available in your community."
