In 2008, quasar established its Laboratory offices with The Ohio State University’s (OSU) Ohio Agricultural Research and Development Center (OARDC) campus in Wooster, Ohio. We also opened a state-of-the-art laboratory in 2017 at our Cleveland Headquarters. quasar partners with the largest university-led agbioscience research center in the nation. Our unique alliance with OSU combines agricultural and biological research to help develop an emerging industry. We provide laboratory services for our customers and for our facilities using quasar technology. quasar’s lab is managed by Dr. Xumeng Ge, formerly of The Ohio State University.


25-Gallon Pilot Scale Digesters:

Our laboratory is home to ten, 25-gallon pilot scale digesters which simulate the performance of the full scale facilities. The compact digesters are also used to stress test the contained system to identify potential issues with biomass such as composition and gas-production performance. Tests done on the substrates determine the levels of active substrate, composition and volume of gas in each digester.



The analytical laboratory is capable of evaluating biomass substrates and gases using a variety of instruments on site. Determination of C (carbon), N (nitrogen), VFA/TIC ratios, free ammonia, % total solids and % volatile solids, and other standard measurements are routinely performed on biomass and digester substrates.
