Last post in this series Kitchen Linker highlighted one extreme version of being frugal to be green, known as freeganism.
Another (of several) way of being frugal to be green is to turn an economist's eye on the problem. Sometimes the results are counterintuitive, e.g., when recycling uses more resources than it saves.
In this kitchen we want to be actually green, as opposed to just going through the motions. To be sure we are meeting this goal, an analytic component is necessary.
What Kitchen Linker really wants is to take the best of freegan philosophy and economic analysis -- and mash them together into something yummy!
