I worked at an office that had 4 separate trash cans to split out things. So you got to stress out on if this disposable plate is in fact cardboard or paper? Or is the fact its covered in grease now makes it food waste? The cleaning service at the end of the day took all of the cans and put them in the same bag before putting it into the dumpster. Where presumably they then filtered the trash and recycling in some capacity (I forget the name). But regardless stage 1 was quite useless. However people were still aghast if I threw the trash in whatever bucket, because recycling is good.
