Solid-State Biodigester Designed for Western Canadian Conditions


With concerns around climate change, the availability of non-renewable resources, and increasing the sustainability of industries as a whole, it is not surprising that organizations like the Prairie Agricultural Machinery Institute (PAMI) are looking at ways to harness energy that is otherwise wasted.

I recently spoke to Joy Agnew, project manager at PAMI, about their Solid State Anaerobic Digester (SSAD) pilot project at the Western Beef Development Centre’s annual field day. The SSAD was actually recognized in June at the 21st European Biomass Conference and Exhibition in Copenhagen, Denmark.  

The majority of biodigesters in Europe and the United States work with liquid material only, making the SSAD in Saskatchewan a unique and exciting project. The SSAD provides an oxygen-free environment for microgorganisms to break down solid waste and collects the resulting gases, which can then be harnessed as energy.

What about the leftover solid material within the digester? Is it valuable as compost? And, will this form of digestion provide a means of bio-security through safe carcass disposal? 

In this video, Agnew explains how the SSAD functions, the by-products that result and the future role it may have in the agriculture industry.
