Reduce. Recycle. Reuse... Memory

I found this on the their website - FYI!

Go Green & Save the Environment with 4 All Memory
It's no secret that once a computer gets upgraded, the old memory modules often get tossed into the trash. Most people don't know that memory modules are made with harmful chemicals and metals that can damage our environment. The good news is that there is a green alternative.
4 All Memory is now offering its customers a way to help people and help the environment. We accept old memory of any size and shape and will either recycle it or donate it to a school or non-profit organization. Either way the old memory modules are kept out of a landfill.

Recycling is easy, all you have to do is mail your RAM to:
