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).
However the definition common to all is a dendritic network polymer of phenyl propene basic units. There are two principal categories of lignin: those which are sulphur bearing and those which are sulphur-free. It is the sulphur bearing lignins which have to date been commercialized. These include lignosulphonates (world annual production of 500,000 tons) and Kraft lignins (under 100,000 tons p.a.). Due to the lack of suitable industrial processes, the sulphur-free lignins are as yet non-commercialized.
