Preeti sent us a lifecycle analysis that should answer, once and for all, that oft-heard question. It's an engaging read, well designed, and full of eye-opening facts. Did you know:
- 7 in 10 Americans do not know plastic is made from petroleum products,
- Paper bags take four times as much energy to produce as plastic bags, and
- To process and recycle 1 ton of plastic bags can cost $4000, which produces $32 worth of recycled product commodity.
Like so many questions about green, the "paper or plastic" one is a bit of a false choice.
We liked the suggestion to carry either a reusable shopping bag, or, better yet, a collapsible plastic crate like the one pictured above, so it's easier to lug the groceries in from the car. (The author does make the assumption that a car is involved in grocery transport, which is not always the case.)
