Packaging: Resealable kraft paper bag and home compostable plant-based film. This is home compostable after use. Otherwise, please check with your local authority as to which bin it should go in. In South Cambridgeshire and Cambridge City, it should be placed in the black waste bin (not the recycling bin). This waste undergoes a six to eight week composting process before going to landfill, during which time the sponge should break down, significantly reducing the waste that goes to landfill.
