July 27, 2017, California - A liquid organic biofertilizer made from the material that is left over after manure or food waste is digested to create clean electricity compares favorably in nutrient value with commonly used synthetic materials in trials on canning tomatoes and corn.

UC Davis professor of biological and agricultural engineering Ruihong Zhang designed an anaerobic biodigester nearly 10 years ago that is used to turn food waste from campus dining halls into clean energy.

Several dairies have also invested in digesters to treat their manure, which would otherwise emit the greenhouse gas methane, and the California Department of Food and Agriculture offers grants to help defray the cost.

Cost is the major stumbling block to more widespread use of the technology, and the trial of a biofertilizer made in the campus digester is an attempt to see if the bottom line can be made just a little more favorable. READ MORE
