Gas Cylinder
Empty cans and hazardous waste
According to municipal rules, completely empty spray cans and gas cylinders should be placed in the city-designated garbage bag (on the day for empty cans and hazardous waste) after using up all contents without puncturing them. If any contents remain, either hand them over to the collection crew without puncturing them yourself, or label them as 'Contains Contents' before disposal. Carbon dioxide cylinders (gas bottles), however, cannot be processed at treatment facilities and must be returned to the seller. They are not collected as regular waste.
