Anaerobic Digestion Benchmark Study Released
British Columbia's Agricultural Research and Development corporation (ARDCORP) released the results of the On-Farm Anaerobic Digestion Benchmark Study in late December 2011. It was undertaken to provide an informational benchmark from which individuals and groups in B.C.'s agricultural sector can inform decisions pertaining to the development of on-farm anaerobic digestion systems.

The benchmarks have been drawn based on the analysis and summation of feasibility studies developed for twelve farm-sites in B.C. The twelve sites were selected with the intention of representing geographic, demographic and circumstantial variances.
The study highlights a key issue within the B.C's government regulations, "the Ministry of Environment's (MOE) proposed On‐farm AD Waste Discharge Authorization essentially limits the volume of non-agricultural feedstocks an on-farm AD system can accept to 25%. As a result, the potential number of economically viable AD systems in B.C. is restricted to a very small number of sites that have an ideal combination of farm size, distance from interconnection and proximity/access to highly desirable feedstocks. If MOE proposed On‐farm AD Waste Discharge Authorization were changed to enable on-farm AD systems to meet the requirements for accepting 49% non-agricultural feedstocks, the number of economically viable sites in B.C. would increase dramatically".
Funding for the study was provided by the Agriculture and Agri-Food Canada through the Canadian Agricultural Adaptation Program (CAAP). In B.C., this program is delivered by the Investment Agriculture Foundation of B.C. Learn more about the Anaerobic Digestion Benchmarking Study here.
