Why don Americans do recycling – paper/glass/cans/plastic etc.?
It depends on the area, and the people involved. Some people are lazy, and there doesnt seem to be enforcement for people who dont recycle. Even where recycling is possible, it seems to be optional. Where I live (outside Tokyo) we have tons of recycling categories, and our burnable trash goes in clear bags so the guys can check it over that recyclable items are not put in there. Also, if someone violates a recycling guideline or puts the wrong stuff out, a warning notice is issued to everyone in the building. Its not a perfect system… but they do take it seriously.
