More than a decade ago, Ruihong Zhang, a professor of biological and agricultural engineering at the University of California, Davis, started working on a problem: How to turn as much organic waste as possible into as much renewable energy as possible.
Last week, on Earth Day, the university and Sacramento-based technology partner CleanWorld unveiled the UC Davis Renewable Energy Anaerobic Digester (READ) at the campus' former landfill.

Instead, they were referring to UC Davis’ environmental stewardship.
With all that UC Davis does to create and promote environmentally friendly programs and facilities, it’s no wonder the university just...
