Abstract:

Liquid and solid de-icing and anti-acing agents comprise neutral or alkaline, non-chloride, non-phosphate and non-glycol compositions that are biodegradable, non-toxic, and environmentally benign. Liquid compositions are based on aqueous solutions of one or more organic acid salts such as lactic acid, succinic acid, acetic acid, and formic acid salts (preferably potassium or sodium). Solid compositions comprise organic-based porous pulp and paper sludge granules impregnated with a liquid de-icing composition or its ingredient(s), and dried. The liquid compositions can be obtained either by direct mixing of commercially available chemicals, or by chemical transformation of commercially available acids, or by fermentation of glucose, sucrose, fructose, or other sugars, or combination thereof.

Abstract:

Glucose is obtained from papermaking sludge by first removing calcium carbonate from the sludge to produce a mixture substantially depleted of calcium and containing cellulose; and then hydrolyzing the calcium-depleted mixture using either a dilute or a strong acid. The glucose, as well as calcium salts removed from the sludge, may be isolated and used in numerous applications.
