Ways To Improve Recycling
1. Wash Station By the Trash
You're supposed to rinse food remnants out of containers, and doing it in the kitchen sink is cumbersome when you also use it for dishes. It there was a fountain or spout (maybe with a refillable tank) near the garbage containers it might be quicker/easier
2. Glass Part 1
Accept glass for curbside pickup (many jurisdictions have this, mine doesn't)
3. Glass Part 2
Accept broken glass. Maybe sell special safety bags to prevent people from cutting themselves.
4. Glass Part 3
Automate the sorting of glass. Stop making consumers sort by size, colour, who-knows-what.
