Etymology: Oil refining gave us the stem "refinery," and "biorefinery" simply bolts the Greek prefix for life onto it. The Greek "bios" (life) became the combining form "bio-," which English uses in hundreds of coinages, from "biology" onward. The older half runs back through Latin "re-" (again) and Old French "refiner," a verb meaning to purify metal again, and the "-ery" ending marks a place or works where something is done. Taken together, "refinery" describes a plant where raw material is processed into something purer or more useful. The compound is a modern technical coinage, formed in English from those two parts rather than inherited from any ancient source. It describes a plant that treats plant or other organic matter in the same spirit as a petroleum refinery treats crude oil, separating it into fuels and chemicals. The prefix carries the sense of living material, so the word names a refinery whose feedstock is biomass rather than fossil oil.
