Too regularly, convenience comes at a cost. Often, that cost is waste, both material waste and energy waste. One particular convenience I always find hard to know what to do with easily is gas cartridges, the Butane/Propane mix canisters many of us use with our stoves. There are ways to dispose of the canisters, but puncturing them easily, and safely is quite difficult. A hammer and screwdriver may well be one way, but how safe is hammer metal surfaces together near the possible remnants of what was in the canister? Well I've found my solution to the problem which also allows for the canister to be more easily recycled.
