Laboratory Services

In 2008, quasar established its laboratory offices at The Ohio State University’s (OSU) Ohio Agricultural Research and Development Center (OARDC) campus in Wooster, Ohio. Partnered with the largest university-led ag-bioscience research center in the nation, our unique alliance with OSU combining agricultural and biological research sets quasar apart in the industry. We provide laboratory services for our customers and the facilities we operate.


Lab Scale Reactors

Our laboratory provides services for the biomethane potential (BMP) of feedstocks, which will be used to evaluate the feasibility of the feedstock for anaerobic digestion based on the energy potentials. The BMP tests are 30-days flask tests (from 250-mL to 2-L) with frequent monitoring of biogas (CH4 and CO2) production.


25-Gallon Pilot Scale Digesters

Our laboratory is home to eight 25-gallon pilot-scale digesters which simulate the performance of full-scale facilities. The compact digesters are used to “stress test” and mimic a system to determine what changes are needed to reach optimal digester potential and identify potential issues with biomass such as gas composition, production, and other performance.
