Moving towards a standard where all food waste is compostable (except, probably, metal cans) seems like a big step forward. Food waste is generally the most unpleasant to handle, so its presence makes sorting the remainder of the stream more difficult. In Japan, some municipalities have a special system for food waste:

- sirmarksalot 8y agoThis sounds like a difficult problem, because compostability and shelf stability are contradictory goals. Pretty much by definition, anything that doesn't break down on a store shelf after a day, is going to pile up in the compost pile. It's not a problem for fresh foods intended to be consumed that day, but if your produce bags were compostable, they would not be very useful.
- sfink 8y agoMy produce bags are compostable, and they work fine. For one, they don't need to last very long - you can't keep produce for weeks anyway. For another, they mostly only break down in the environment of a municipal composting system, which gets hot and is quite different from your backyard compost heap. Grocery stores around where i live in the sf bay area seem to be switching to them. I think they tried earlier, but I'm guessing they were too much more expensive? Quite a marvel of engineering, from what i can tell. Your point still stands though - shelf packaging needs to be pretty robust.
