CALCIUM MAGNESIUM ACETATE AT LOWER PRODUCTION COST: PRODUCTION OF CMA DEICER FROM CHEESE WHEY
This TechBrief announces the completion of a Federal Highway Administration study that is fully documented in a separate report (FHWA-RD-98-174) of the same title. Calcium magnesium acetate (CMA) has deicing ability comparable to salt, but is noncorrosive to vehicles, not harmful to highway concrete and vegetation, and has no significant health or environmental concerns. It is, however, expensive as compared to salt and other deicers. The goal of this project was to develop low-cost acetate deicers from cheap feedstocks such as cheese whey and other industrial wastes. A novel fibrous bed bioreactor and an energy-efficient solvent-extraction process were developed. The technical feasibility of the proposed fermentation and extraction processes was evaluated at the bench scale in the Phase I study and at the pilot scale in the Phase II study. Economic and market analyses were also conducted to determine the commercial potential of these processes.
