In the early 90's, NY went big for this. There were strict rules and procedures galore. You had to buy special clear bags, state approved and issued, to put your regular garbage in. Collectors could sift through it and reject it outright if one stray catfood can was amidst the kleenex. There were special stickers and fees and bins and regulations, and snoopery, and all differed among the many and various towns. Neighbors could see and count your wine and liquor bottles right at curbside. It collapsed on itself while I was away in CT. People got sick of it, and so did the municipal gov'ts.
Now, it's voluntary. The mayor said on his radio program yesterday that "all that stuff ends up in the same landfill altogether anyway."
