Biomass bioconversion to calcium magnesium acetate deicing salt. Final project report on Phase 1
The project experimentally investigated using biomass as feedstock for conversion to calcium magnesium acetate (CMA), an alternative road salt. This new organic road salt will prevent corrosion of bridge decks, underground cables, and rusting of cars and trucks. CMA from biomass will reduce costs, compared to petroleum and natural gas for making this material. Phase I work focused on bioconversion of sewage sludge residuals to CMA. The process is based on a packed bed fermenter to produce acetic acid from biomass, as well as liquid ion exchange to recover acetic acid from the fermenter broth prior to the final production step which occurs by passing the acetic acid over limestone. In Phase I: (1) percent bioconversion and kinetics of biomass to acetic acid have been confirmed in small batch fermenters; (2) equilibrium constants for acetic acid recovery via liquid ion exchange have been documented; and (3) rates of conversion to CMA have been determined.
