I was introduced to this concept at BIONEERS, an annual event with satellite nodes convenient to all, and was just blown away. This book is a superb introduction to the common sense recognition that nature has over all the billions of years, figured out how to not only do stuff with energy efficiency, but also with a zero waste footprint.
Check out World Index for Social and Environmental Responsibility (WISER) for many other leads.
