Onstage at today’s hardware announcement event, Apple proudly announced that the 2018 models of its MacBook Air and Mac mini would both be manufactured with 100 percent recycled aluminum. Additionally, it announced that its Mac mini would be constructed from 60 percent recycled plastic.

These are different kinds of recycled materials. Specifically, the recycled plastic is “post-consumer” which means that it’s material that’s previously been used in other products and recycled. Meanwhile, the aluminum is recycled leftovers from Apple’s production of other aluminum products. In other words, you’re not getting a laptop made out of old drinks cans.
