Why? Aluminum production needs a lot of electricity but if you recycle back, costs goes down, total aluminum energy cost of Apple is likely much lower than all those servers running throughout the year.
- dredmorbius 10y agoRecycling rates are generally pretty low. I think the highesst rates have been ~80% for lead (batteries). For aluminium in the US, it's closer to 40% IIRC.
