The machine shop in EME 0220 does its best to recycle pure aluminum. There are two main categories of metal-based waste:
Aluminum: If your aluminum waste is pure, it can be disposed of in the aluminum bins.
Steel: Practically accommodates any metal waste, including impure aluminum.
There are one to two bins of each type at anytime within EME 0220.
If you are unsure of which type of metal waste you have, you can reach out via the Technical Support Group Ticket System.
