Using the abv percentage, I'd figure out the cost of three ounces of straight alcohol. Then, based on the price per ounce of each type of booze, I'd figure out the cheapest ways to get the most alcohol. So the formula is... See, kids -- the stuff you're learning in math class does come up in real life.
Lignin. Definition. noun. An organic substance that acts as a binder for the cellulose fibers in certain plants adding strength and stiffness to the cell walls. Supplement. Lignin is an organic substance belonging to a group of aromatic alcohols. It is naturally produced by certain plants (especially woody plants and certain algal species).
Lignin is produced in industry as a by-product of the production of cellulose (sulfate lignin, ligninsulfonic acids) and the hydrolysis of plant materials (hydrolytic lignin). Lignin is a valuable chemical raw material; as yet, far from complete use is being made of it. Sulfate lignin can be used as a strengthener in synthetic rubber and as a plasticizer in ceramic production.
