Quite a few things are compostable in industrial scale municipal compost systems, where there are higher temperatures then the bin in the back yard. We compost food scraps to use in the garden, and it generally works great. What we found was that certain items just never broke down, like certain tea bags that have what looks like a plastic tetrahedron instead of a filter-paper bag. The bags end up getting scattered about by our chickens, and eventually picked up and thrown away by ourselves. So, we don't buy those any more.
