In this article, note the reference to biomimicry with respect to bio-cleantech.
"A third area of "bio-cleantech" is adapting the successful engineering found in nature, which usually does things without a lot of energy input and no waste or toxins ("biomimetics").
Bianca added: "Did you know that the geometry of whale fins can provide streamlining benefits if applied to objects moving through a fluid or help reduce the huge amount of pumping energy used in the water industry? Or that spider silk is seven times stronger than steel, and that it is now being mimicked?"
