The recycling company behind the initiative, TerraCycle UK, will process and sort the inhalers into material type, with the recycled components sold on for use in new products. The recovered aerosol will be sent to a specialist company who will recycle the metal components and collect any remaining liquid or propellant gas. The gas is then used as a replacement fuel in high temperature incinerators and cement kilns. No part of the aerosol container goes to landfill.
