Liam was announced back in March during Apple's event where they detailed its workings. It is able to recycle all the materials and parts used in an iPhone and can do that at a fast pace. Apple has been using it to recycle tons of iPhones and has recovered gold worth $40 million (2,204 pounds) and copper worth $6 million from the devices. Before you go ahead and open up your iPhone to find gold, it is approximately only 35gm of gold. It is a huge amount in terms of both cost and reusable material.
