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.
