Walmart’s grocery department will soon begin switching from petroleum based plastic clamshells to corn-based packaging. The potentially revolutionary news replaces an astonishing 114 Million plastic containers.
Despite my generally poor feelings about Walmart, I’m pretty impressed – the potential impact on the bio plastics imdustry is enormous, as if McDonalds suddenly went all-organic.
That said, high petroleum prices undoubtedly played as much a roll in their decision as anything else. Furthermore, as pointed out on Treehugger, bio-plastics are often derived from genetically modified crops, and I have also seen reports that some bio-plastics (ironically) use as much fossil fuel as regular plastic due to the use of petroleum based fertilizers. But why look a gift horse in the mouth? Bravo Walmart. (via Treehugger)
