Whipped cream chargers are steel cylinders rounded at one end and have a narrow tip at 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.
Once used they 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 in the UK is only 46%.
Most recovery of steel is achieved with a large magnet to separate it from other household waste at landfills. There are many recycling locations that you can take your empty cream supplies. The best way to find your local steel recycling centre is to visit www.recyclemetals.org. and simply type in your postcode to find the centre nearest you.
