Executed Projects

quasar’s first facility built was in Akron, OH, Phase 1 for KB BioEnergy with a 5,000 dry to per year anaerobic digestion system.

City of Alliance WWTP project included a Class A Biosolid upgrade. Class A biosolids benefits the city by increasing disposal flexibility, reducing disposal costs while improving the city’s overall processing of biosolids.

quasar’s Lime Lakes facility can process 42,000 tons per year and can generate up to 810 kw electricity. Expansion is planned.

The Jordan Dairy Farm in Rutland, MA was built in 2011 and expanded in2016. The digester processes 20,000 tons of food waste and over 9,000 tons of manure annually. Each year this site produces 800kw and 4,200 MWh of renewable energy with 2 engines, offsetting 770 tons of CO2 emissions annually.

The facility was designed to accept 530,000 gallons per day and produce over 4MMBTU per day. The renewable natural gas faciliy located in Maricopa, AZ. RNG is then injected into a natural gas pipline and trasported to California.

Niagara Bioenergy was designed to process 35,000 tons of biomass per year and the ability to provide 1 MW of combined heat and power.

Lucas County digester upgrade to allow biosolids, regional food waste, and fog.  Installation of Centrifuges, centrifuge building, sludge storage building, flexible membrane roofs, solid and liquid receiving, mixing, flare, heat exchangers and front-end Class A process. quasar continues to manage incoming biomass management services.

quasar performed a retrofit project for the City of Wooster’s Water Pollution Control.  The result was a tank capacity of 1.8 million gallons, with an annual input of 100,00 wet tons.  Energy generation is capable of 1MW electricity per hour.

In Greenville, Michigan, the Greenville Circularity Center converts methane released from dairy manure into renewable natural gas each year, utilizing one digester. The RNG produced at Greenville is injected into the ANR Pipeline.  Developed in partnership with Chevron, the center is now fully operational.

The Sanborn Circularity Center in Sanborn, Iowa, features two anaerobic digesters at Van Ess Dairy Farm in O’Brien County.  Manure from the farm will be converted into renewable natural gas (RNG) for transportation, industrial heating, and other uses.  Van Ess is part of the third tranche of projects under the Brightmark RNG Holdings LLC and Chevron U.S.A. Inc., joint venture. The quasar digester is fully operational and has exceeded performance guarantees.

The Centerville Circularity Center in Centerville, Iowa, includes the construction of one new anaerobic digester on the Black Soil Dairy Farm.  The manure from this farm produces renewable natural gas each year.  The biogas generated by this manure is captured, cleaned, and converted into RNG, which can be used as transportation fuel, industrial heating, and a host of other applications.  Centerville is part of the third tranche of projects developed under the Brightmark RNG Holdings LLC joint venture with Chevron U.S.A. Inc. The quasar digester portion of the project has exceeded all performance guaranties.

The Paullina Circularity Center in Paullina, Iowa, was built with a large CSTR digester at Roorda Dairy Farm in O’Brien County. Manure from the farm has produced biogas that has been captured, cleaned, and converted into RNG for transportation, heating, and other uses. As part of the Brightmark-Chevron joint venture, the quasar digester has been fully operational and has exceeded performance guarantees.

The Wayland Circularity Center in Wayland, Michigan, includes building a new anaerobic digester on Crossroads Farms in Allegan County.  The manure from this farm produces renewable natural gas each year.  The biogas generated by this manure is captured, cleaned, and converted into RNG.  Crossroads is part of the third tranche of projects developed under the Brightmark RNG Holdings LLC joint venture with Chevron U.S.A. Inc.  The center was completed in 2025.
