Glycerol is produced as a byproduct of biodiesel production at a rate of about ten percent. The main market for glycerol is in the manufacturing of cosmetics, but that market is saturated. Another use is as a potential energy feedstock since glycerol contains about 120,000 Btu/gallon. While containing energy, its combustion problems are significant; it has high viscosity, a high ignition temperature, and produces a toxin combustion byproduct. Recent research has shown promise for energy conversion by anaerobic digesting to methane gas. The proposed research will investigate the loading rate and operational parameters for co-digesting crude glycerol and swine manure in a bench scale...
The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
