Nearly a decade ago, campus leaders at UC Davis decided to invest in a small team of employees to reduce energy by optimizing building controls and systems. The concept was that UC Davis could fund such a team, if it could curb high utility bills — essentially having the team pay for itself with energy savings.
Tucked away on the west side of campus, UC Davis’ READ facility receives 20 tons of food waste per day from customers including local grocery stores and our own campus dining commons. With the improvements a recent $4.77M CalRecycle grant provides, the READ facility becomes an important part of UC Davis’ strategy to eliminate the use of fossil fuels from its operations and fight climate change.
Since taking ownership in 2017, UC Davis Facilities Management has dedicated itself to revitalizing the READ facility, working with academic and industry experts to find creative solutions including the development of an ammonia extraction system that processes the ammonia-rich digestate, separating it into nearly ammonia-free digestate and concentrated ammonia. The ammonia-free digestate can be processed at the campus’s wastewater treatment plant, or by other means, locally without adding excess nutrients to inland waters. The concentrated ammonia product has now become a valuable commodity purchased by California Safe Soil as an ingredient in the formulation of a certified organic fertilizer.
