摘要：	In an effort to find an efficient, economical, and environmentally acceptable treatment for pavements to remove ice and snow on roadways, the Federal Highway Administration (FHWA) conducted a study, which found that calcium magnesium acetate (CMA) was an excellent alternative deicer to salt. This article summarizes the results of significant studies pertaining to CMA use, the environmental aspects of using CMA, and relevant federal legislation. Viable methods for producing low-cost CMA using cheese whey and other solid wastes have been developed. CMA produced by these methods had acceptable deicing properties, comparing favorably with commercially produced CMA. Based on their purity, the CMA products should have negligible adverse safety and health impacts. Undesirable environmental impacts should also be negligible. In fact, using waste materials in the processes, in addition to lowering the cost of CMA, has a positive overall environmental impact. The excellent corrosion-inhibiting properties of commercial CMA products have been clearly demonstrated using electrochemical impedance spectroscopy.
