- Innovative biofilter based on construction residues for the deodorization of industrial atmospheric emissions

Sanimax inc. is a family business that has been developing animal by-products for nearly 80 years. The deodorization of the ambient air of this plant is provided by seven biofiltration units totaling 4,200 m2 of surface. Sanimax inc. and the CRIQ felt it was appropriate to carry out this R & D project in order to improve environmental performance while reducing the costs of biotechnology. The identification and analysis of the materials as well as their deposit were carried out in collaboration with the Centre de Transfert technologique en Écologie Industrielle. The tests aimed at determining and comparing the purification and aeraulic performances of the different packings were carried out using a test bench in real conditions over a period of six months. This presentation will reveal the main results obtained as well as the very interesting economic, environmental and social perspectives for the scaling up of this new biotechnology.

- CO2 Capture and Conversion : When Emissions turn to Value Added Products

If we consider CO2 not as a pollutant but as a waste, the 3RV rule applies to it. Thus by capturing and converting it into useful products, we place ourselves in a perspective of recycling and recovery. Today's advanced CO2 capture technologies open the door to a cleaner conversion and recovery of CO2 at lower costs. In this presentation, estimates of the GHG emission reduction potential of conversion technologies are presented by families of similar technologies. A ranking of final product families is based on the amount of GHG emission reduction achieved. The findings show that some products stand out for their ability to leverage GHG reductions. As GHG reduction policies spread and carbon prices rise, doors open to new markets for CO2-based products.

- Methane mitigation from an underground coal mine with the VAMOX® technology for the generation of carbon credits.

Methane emitted through underground coal mine ventilation air, known as Ventilation Air Methane (VAM) is a potent greenhouse gas (GHG) having a global warming potential 25 times more powerful than CO2. Global VAM emissions are estimated to contribute close to 700 million tonnes of carbon dioxide equivalent (MtCO2e) annually. Based on the experience of its first VAM abatement project carried in Alabama from 2009 to 2013, Biothermica has completed the design of a Second-generation Vamox® Regenerative Thermal Oxidizer (RTO) system fully optimized to mitigate VAM emissions, and will be implementing its technology at one of the largest underground metallurgical coal mine in the United States in 2019. This $ 15-million project will be the largest of its kind in America and will lead to the mitigation of 530,000 tCO2e per year. It will be financed through the sale of carbon offsets on the Québec-California regulated market.
