Value Village ／ Everyday know-how
This answer is a draft. It stays unpublished until legal review and source verification are complete.
Seen from outside, household waste separation here looks like unusual diligence. Seen from inside, it is 1,741 local systems, each with a calendar.
Household waste is the responsibility of each of 1,741 municipalities (Ministry of the Environment, FY2023 survey). Each sets its own categories, collection days and rules. Residents work to that calendar — and check it, because it is not obvious.
Some separation exists for safety rather than recycling: batteries, aerosols and sharp items are handled apart to protect collection workers and vehicles.
[Verify] Municipality count from the Ministry of the Environment's FY2023 survey. Confirm before publication.
Categories and collection days are set by the municipality. Households work to that calendar.
See the safety categories above. Not everything is about material recovery.
A quick rinse prevents odour and contamination of the collected material. The alternative is a bin that cannot be stored for several days.
Once sorting happens at the moment of disposal, there is nothing to sort later. The work moves rather than increases.
Residents check the calendar too. Municipalities publish leaflets precisely because it is not obvious.
