Whipped cream chargers are steel cylinders rounded at one end & and narrow tip on the other. They are filled with 100% nitrous oxide. The cream canister’s wall is approx 2mm thick so that it can withstand the pressure created when using with a cream whipper.
Once used the chargers cannot be refilled, but these canisters are 100% recyclable. Metal can be recycled indefinitely without losing any of its properties. However, the recycling rate of steel packaging is only 46%. Most recover of steel is done with a large magnet to separate it from other household waste at landfills. There are recycling locations that you can take your empty cream supplies.
