Reference number : GC-2017-Q1-00374, amendment number : , agreement type : G, recipient legal name : Zeman, Frank (Royal Military College of Canada)|Zeman, Frank (Collège militaire royal du Canada), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Composting is an established waste management option that diverts organic waste from city landfills, stabilizes_x000D_
it and recycles the residue for agriculture. Typically, composting is an outdoor process where the organic_x000D_
material is stockpiled in windrows (long piles) that can be turned periodically to enhance biological activity._x000D_
The biological activity is enhanced by ensuring adequate oxygen for the microbes, that is moving material from_x000D_
inside the pile to the surface. The biological activity converts a portion of the organic matter to carbon dioxide_x000D_
and water thus releasing heat. These gases, and heat, are vented to the atmosphere with normal composting_x000D_
producing carbon dioxide concentrations of about 6% by volume. Carbon dioxide is a valuable industrial gas_x000D_
and will soon be valued through the national carbon plan yet to be unveiled. The coming price on carbon there_x000D_
will be added costs to consumers of industrial CO2, which is normally sourced from refineries or other_x000D_
concentrated, fossil fuel based, sources._x000D_
We will be investigating a closed system that allows for capturing of the CO2 produced by the composting_x000D_
process while potentially increasing the biological activity rate. The main focus of the project will be to_x000D_
increase the CO2 concentration in the compost exhaust, capture the exhaust to facilitate the separation process_x000D_
and increase the oxygen availability to the bacteria. This will be accomplished by testing several redesigns of_x000D_
the composting process including increasing the air flow, blending exhaust air with fresh air (raising CO2_x000D_
levels), using produced oxygen (e.g. from air separation either pure or blended) and moving the compost on a_x000D_
moving grate system. The performance improvement of these methods will be converted into a cost per tonne_x000D_
of CO2 captured where possible., program purpose french : Composting is an established waste management option that diverts organic waste from city landfills, stabilizes_x000D_
