Trash Lens - Smart Waste Separation in Tōkai

Tōkai

Supported!

Gas Cylinder

Resource Container (Can)/Collection Category: Resource (Can)

Spray cans and cassette-type gas cylinders with remaining contents should be placed in the dedicated recycling boxes at resource collection sites without puncturing them. These boxes are located at the permanent resource sorting collection site (inside the Recycling Center, daily), resource sorting collection hubs (13 locations citywide, Thursdays), and the Recycling Center administration building (Monday through Friday). Empty spray cans and cassette-type gas cylinders should be placed in a separate yellow resource collection bag (not with other beverage cans, etc.), without puncturing them. Write "Spray Cans" on a white piece of paper, attach it, and place the bag at the designated waste collection point on the resource (cans) collection day. Puncturing them or placing them in regular collection with remaining contents is strictly prohibited, as it can cause ignition, explosion, or fire in garbage trucks or processing facilities.
