The addition of organic substrates to the farm digesters will be evaluated for enhanced biogas production and reactor stability. Lab scale experiments will be utilized to evaluate and select appropriate co-substrates for farm scale digester testing and to optimize manure and co-substrate mixtures (C:N), temperature, pH and moisture content to enhance biogas production. The use of co-substrates to enhance biogas production will be verified in farm scale anaerobic digesters. Read more about the results here.
