ABSTRACT:
An improved process for the production of road deicer products preferably containing calcium magnesium acetate or calcium magnesium acetate/calcium magnesium propionate is provided. The process involves first providing a residual water plant sludge starting material containing calcium and magnesium compounds, and reacting this sludge with stoichiometric quantities of at least acetic acid and more preferably both acetic and propionic acids. The resultant reaction product can then be dried, ground and granulated to provide a dry, free flowing road deicer product.
