Aluminum can be recycled over and over and over but did you ever think of upcycling it?
Recycling tears down to the raw materials and recreates. Upcycling takes what it
is and makes it better, no downcycling involved.
For instance, if you cut up a coke can and make it a piece of art that is upcycling... if
you take that can to your local recycler, they mash it up, tear it down, melt it, combine
it with other aluminum ... things... and then make something new.
