Non-combustible waste / Resource recovery (special collection bag)
Spray cans and cassette gas cylinders used at home must be completely emptied outdoors without puncturing them. Only spray cans and cassette gas cylinders that have been completely emptied should be placed in the designated used spray can collection bags at the collection site. Special collection bags are not distributed to individual households. Do not place any waste other than spray cans in the collection bags. Collection sites set up by neighborhood associations must follow the association's rules. Items from businesses are excluded. For a list of collection points and details, contact the Kariya City Waste Reduction Promotion Division.
