Itochu Metals and Daikin have formed a resource recycling partnership to recover high-purity aluminium and copper from used commercial air conditioners across Japan. Daikin estimates that a small mass-produced commercial air conditioner contains around 8 kg of copper and 7 kg of aluminium. If scaled to 300,000 units annually, the system could recover around 2,300 tonnes of copper scrap and 2,000 tonnes of aluminium scrap.
