Calcium Magnesium Acetate at Lower-Production Cost: Production of CMA Deicer from211 Cheese Whey

摘要

Calcium magnesium acetate (CMA), a mixture of calcium acetate and magnesium211u001eacetate, is used as an environmentally benign roadway deicer. The present 211u001ecommercial CMA deicer made from glacial acetic acid and dolomitic lime or 211u001elimestone is expensive compared with salt and other deicers. Also, a liquid 211u001epotassium acetate deicer is used to replace urea and glycol in airport runway 211u001edeicing. The goal of this project was to develop low-cost acetate deicers from 211u001echeap feedstocks, such as biomass and industrial wastes, via fermentation.
