A new process for producing Ca/Mg acetate deicer with Ca/Mg waste and acetic acid produced by wet oxidation of organic waste

A new process for producing calcium magnesium acetate (CMA) deicer with acetic acid, produced by wet oxidation of organic wastes, and Ca/Mg wastes is proposed. Four kinds of representative organic waste were used as low-cost raw materials, for production of acetic acid, which was then converted to CMA by mixing with a Ca/Mg source such as oyster shells and industrial Mg wastes. The conversion efficiencies to acetic acid and from acetic acid to CMA achieved 14-16% and higher than 99%, respectively.
