Oh yeah, got the alliteration! GO-GREEN (I'm not shouting, that's the way they print it) a packaging supplier in Edgerton, Wisconsin, offers polypropylene packaging that significantly reduces CO2 emissions, scrap rate, and water and energy use. If the designer is creative enough, The GO-GREEN system can be used without any cardboard packaging. This results in a huge additional reduction in energy used in packaging.

Upcyclers Preserve and Terracycle offer postage free polypropylene collection and Preserve has established a number of drop-off points as well at participating Whole Foods locations.
