In my town we have 3 categories. Each category is collected once a week.
- Burnable garbage - food scraps, tissue, disposable chopsticks, toothpicks, cotton swabs and small pieces of paper (in case there's confidential information)
- Recyclables
*Paper garbage - paper packaging, any paper material with the 紙 label
*Plastic garbage - food packaging, shopping bags, plastic wrap, with the プラ label
*Milk and juice cartons with the 紙パックlabel, cut, wash, dry and bundle
*Metal cans - from canned food, coffee, beer etc.
*Pet bottles (without the plastic tag and cap) and glass bottles
*Magazines and books
*Cardboard
- General garbage - aluminum foil, old clothes, dish sponges, broken dishes and other things that don't belong...
There's a poster with the day of collection and what kind of garbage goes in which bag on my wall. There's also a more detailed book that lists a lot of things.
