There's no biz like methane biz

C/net news.com reports on a grad student's original and imaginative business plan to recover methane from organic waste. The waste he has in mind is the vegetable leavings and paper discarded by supermarkets. I see this as an urban equivalent to manure-generated methane down on the farm. C/net reported that the student, Shane Etan, never saw himself as an environmentalist. But let's face it, this is huge for the environment, because methane is a killer greenhouse gas. His business plan calls for converting supermarket waste into methane, liquid fertilizer, and solid compost. Presumably he shows how this can be done profitably. Calling all grocers. Wouldn't this be the perfect marketing tool for Whole Foods?
