Because there is no need to mine, their production creates less waste, while reusing a precious resource. If You Care Aluminium Foil protects food against light, oxygen, humidity and bacteria. It is not recommended for use with acidic or fatty foods. If You Care Aluminium Foil can be recycled again, provided that your local recycling centre accepts aluminium foil - always ring your bin management company to check!
