We have 3 bins
1. General trash
2. plastic and aluminum bottles cans, etc.
3. cardboard.
Our esteemed trash collection company collects everything in 1 truck (previous trash company had 2 separate trucks).
Theres 2 compactor bins in the current truck. They take bin#2 and put it in one compactor bin. They put #1 & #3 together in the other compactor bin.
So everyone dutifully separates the cardboard (#3) from the general trash (#1) and the trash collectors throw it all in the same compactor bin. Lol
