HDR Wins Contract for Organic Waste Anaerobic Digestion Unit

Heartland Biogas LLC has awarded a contract to HDR Constructors Inc. for an anaerobic digester facility in Weld County near LaSalle, Colo.

Kansas City-based HDR said in a news release it was awarded a contract for the design, construction and startup of a 20-megawatt equivalent anaerobic digester using organic waste to create natural gas.

The Heartland Biogas project is owned by San Diego-based EDF Renewable Energy and was developed by Hampton, N.H.-based AgEnergy USA.

The facility will use organic waste including cow manure from local dairy operations and other organic wastes or from the Denver metropolitan area, such as restaurant grease trap waste, spoiled products from retail grocers and food processing residuals. The digester will produce renewable natural gas, organic compost amendment and liquid soil amendment products.

The companies expects the facility to be fully operational in 2015 and capable of exporting 1.5 billion cubic feet of renewable natural gas annually, making it one of the largest anaerobic digester facilities in North America. Construction started in August.

HDR also designed the Gills Onions Advanced Energy Recovery System facility located in Oxnard, Calif., which produces renewable fuel from onion waste.
