I recently came across this article on one of the Gardenweb forums that I found very interesting. If you haven’t read the article itself, this spring Procter & Gamble are releasing Tide PurClean: an eco-friendly version of Tide that is made with 65% plant-based ingredients. On top of that, this week it was announced that Procter&Gamble received biobased certification from the USDA’s BioPreferred Program for Tide PurClean. What exactly is “biobased”? In short, derived from renewable materials such as plants instead of non-renewable petroleum-based products. By the way, P&G started working on the development of biobased chemicals back in 2011 as part of a larger sustainability initiative.
