ABSTRACT:
A process for production of mixed calcium-magnesium organic acid salts useful for de-icing obtained by anaerobic hydrolysis-fermentation of organic carbonaceous solids by a biologically active mixture of hydrolysis-fermentation anaerobes in which the growth of methanogenic bacteria is suppressed and calcium-magnesium oxygen containing compound is added to the anaerobic digester to control pH and to react with the fermentation acid products to form a mixture of calcium-magnesium organic acid salts. The calcium-magnesium organic acid salts may be readily recovered in solid form for economical utilization in roadway de-icing. The anaerobic digestion is conducted under a naturally obtained mixed microbial population in the presence of the calcium-magnesium oxide containing compound, eliminating the need for pure microbiological strains and sterilization or pasteurization of feed materials.
