While global brands including HP, Huawei, Amazon and Microsoft also have detailed protocols for recycling their products, Apple’s are the most rigid and exacting, according to people involved in the processes, who declined to be identified because they’re not authorized to speak about clients.

More stringent testing then shows whether the handset can be resold or must be scrapped.
