Biofiltration

Modern industrial and municipal facilities can release odours and potentially harmful emissions into the atmosphere. Biofiltration is an established technology for treating these emissions and reducing them to safe, acceptable levels. 

Our Waste Management team has designed, built and tested two pilot biofiltration plants for treating odours from composting facilities and for reducing sulphur emissions from wastewater treatment plants. 

We have also designed, built and tested a pilot biofiltration system that passively treats methane emissions from smaller landfills where landfill gas capture and collection is not economically feasible. This system lowers methane emissions by 90 per cent. By reducing greenhouse gas emissions, landfill owners can earn potential carbon credits and offsets.  

Our team is testing a new technology, which potentially can increase methane removal capabilities through active biofiltration. This technology has delivered promising bench-scale results in dealing with higher quantities of landfill gas from landfills that are currently flaring or have to maintain landfill gas collection for health and safety reasons.

We are currently developing a prototype and plan to field test this technology at a landfill in the Edmonton area.

 We are looking for partners who are interested in commercializing this technology.
