The eco-friendly designs of the new MacBook Air and Mac mini extends beyond aluminum. The bottom cover and connector wall in the new Mac mini, for example, are made from 60 percent recycled plastic, while its fan contains 27 percent bio-based plastic made with renewable sources rather than petroleum.
Likewise, the vent and speakers in the new MacBook Air contain 35 percent and 45 percent recycled plastic respectively. The butterfly switches on the new MacBook Air's keyboard also contain 34 percent bio-based plastic, while the solder on the main logic board is made from 100 percent recycled tin.
Apple says the new Mac mini generates 45 percent fewer emissions than the previous-generation model, while the new MacBook Air generates 47 percent fewer emissions than the previous-generation model, each over a four-year lifespan.
Apple also says the new MacBook Air's packaging uses 87 percent less plastic than the previous-generation model's packaging.
Apple's ultimate goal is to use only recycled or renewable materials in its products, and source them responsibly, and it has certainly taken further steps forward with the latest MacBook Air and Mac mini.
