This research into safer, less toxic plastics was really interesting. there where also many other green materials and process’ being discussed on this site. The use Polypropylene plastic being already labeled as a recyclable materiel is what drew me into this article.

I think anyone looking into materiel studies should take a gander over the articles on this site. There is a lot of knowledge being shared here.
