Alcohol is produced by fermentation from vegetable substances containing starch or sugar, from fermentable sugars produced by the hydrolysis of cellulosic bodies, and synthetically from calcium carbide and from the ethylene contained in coal and coke-oven gases.
The use of non-foodstuffs, or cellulosic materials, such as grasses, reeds, straws, peat, waste wood, sawdust, etc., is not yet possible, for, although research work is in progress to discover a process that could be worked on a commercial basis in those regions where such materials exist in sufficient abundance, it has not so far led to any definite results.
During the 20th Century production of man-made cellulosics steadily increased to reach a peak of 3.5 million tons in 1970.
