ReFuel Your Fun: Choose Refillable Gas Cylinders June 4, 2017 Email 6-4-2017 Going camping this summer? If you pack a camp stove, use a refillable gas cylinder instead of a disposable one. Eighty percent of what you spend on a gas cylinder goes towards the container and convenience, not the gas itself. A lot of people use camp stoves each year — adding up to 4 million disposable cylinders annually in California alone — so it makes both environmental and economic sense to refill your gas cylinder instead of tossing it. The ReFuel Your Fun Campaign began by promoting refillable gas cylinders in California, and has now spread across the U.S. Find out where you can pick up a refillable cylinder to refuel — and save money — on your summer fun.
