GE technology to convert food waste into biogas at Utah project

By GE, via Biomass Magazine.

The Wasatch Resource Recovery project in North Salt Lake City, Utah, has selected GE's Monsal advanced anaerobic digestion technologies to convert food waste into biogas to generate renewable energy and fertilizer. The first phase will generate up to 3,000 dekatherms a day of renewable natural gas (RNG). Once both phases are operational, WRR will supply enough RNG to meet the needs of approximately 40,000 people or 15,000 homes.

According to the United Nations, approximately one-third of the food produced in the world for human consumption annually gets lost or wasted. The WRR project—a joint venture between ALPRO Energy and Water and the South Davis Sewer District—will become a state-of-the-art food waste digestion facility that will divert 180,000 tons of food waste per year from area landfills, extending the life of these landfills as well as reducing greenhouse gas emissions equivalent to taking 12,000 cars off the highway.
