Material efficiency

General desciption of Material efficiency:

Material efficiency is a description or metric which expresses the degree in which raw materials are consumed, incorporated, or wasted, as compared to previous measures in construction / manufacturing projects or physical processes.  Making a usable item out of thinner stock than a prior version increases the material efficiency of the manufacturing process.  (from https://en.wikipedia.org/wiki/Material_efficiency)
