How to Dispose of Propane Tanks and Gas Cylinders

Propane tanks, butane canisters, and small camping gas cylinders are severe explosion hazards. Placing pressurized cylinders into curbside garbage carts or recycling bins can ignite inside compactor trucks or explode inside metal recycling shredders.

Key Takeaway

Local hardware stores, gas suppliers, and county hazardous waste days will accept old cylinders for safe decommissioning. Always verify your local municipal hauler requirements before placing large items at the curb.

Step-by-Step Instructions

1
Check if the tank still contains propane gas

Never attempt to vent or bleed flammable gas into open air or enclosed spaces.

2
Exchange empty 20-pound BBQ grill tanks at a local retailer

Take barbecue cylinders to retail exchange kiosks at grocery stores, hardware stores, or gas stations like Blue Rhino or AmeriGas.

3
Take damaged or expired tanks to a certified propane supplier

Cylinders older than 12 years require requalification or disposal through certified gas distributors.

4
Recycle 1-pound camping canisters at hazardous waste centers

Many national parks and county hazardous waste transfer stations collect single-use green camping cylinders.

⚠️ Important Rules to Avoid Fines & Hazards

  • Never place propane cylinders of any size in curbside trash or blue recycling bins.
  • Do not puncture or crush gas cylinders, even if you believe they are completely empty.
  • Store cylinders upright in a well-ventilated outdoor space away from open flames, electrical equipment, and direct sunlight prior to disposal.
