For this newsletter, we would like to share information on the tools we use, on a daily basis, for odour abatement and air treatment. These tools rely on industry best practices and aim to enhance cohabitation with the community.

Successful operations in the past few months

As a direct result of the implementation of our production line robustness plan and the investments made since the fall of 2019, we are proud of the progress made at our Montreal plant during July, August and September. While we still have more progress to make, we are confident that our action plan will be successfully deployed and implemented. 

The management and engineering teams are maintaining their Sunday coordination meeting to ensure a successful start of operations each Monday. Production start-ups are critical to the proper course of the production week. In addition, the investments made ensure the robustness of our production, which has not experienced any unplanned shutdowns in recent months. We intend to continue our investments in robustness for our production lines in the coming months.

Air treatment

The quality of operations is directly linked to our ability to effectively treat the air. Our processes are designed to abate odorous compounds present in the air from our production operations. Respecting very high-quality standards, our Rivière-des-Prairies plant combines two different types of air treatment to abate the odorous compounds associated with the organic matter received and treated at our plant.

1. Incineration boilers and negative pressure in the plant

Our plant uses “negative pressure” ventilation systems, which means that all air is ” vacuumed ” into the plant so that it does not escape to the outside and is directed to our various odour treatment and abatement systems. In addition, all our production equipment is fitted with direct air intakes to quickly capture and direct process air directly to our odour treatment and abatement equipment.

Part of the air drawn in through the aspiration ducts installed on the plant’s equipment is directed to an incineration process. This thermal treatment process provides very high performance in the abatement of odorous compounds.

2. Wet scrubbers

Another part of the air is directed to different chemical scrubbers. These chemical scrubbers are equipped with equipment for the precise measurement and addition of chemicals. These chemicals allow the neutralization of odorous compounds from the organic matter received at our plant. The real-time monitoring of these various operating parameters by a trained and qualified team allows for the continuous adjustment of the processes to optimize them. Finally, a dedicated team makes frequent rounds to ensure the absence of odours. This team is also deployed in the field as soon as an odour complaint is transmitted to us.

Mist park

Since receiving organic matter can be a source of indirect odours from the plant processes, Sanimax installed two odour abatement misting systems, one surrounding the truck waiting area and the other surrounding the truck scale and the entire northern limit of its property (on the fence along Maurice-Duplessis Boulevard),

Operating 24 hours a day, 7 days a week during the summer months, the mist is used to control and mitigate odours from the matter received by the Sanimax plant. The system uses water and a product certified by Health Canada.

Thanks to all these different systems, processes and techniques, we continuously ensure that potential odours are controlled ahead of time to avoid odour episodes.

We remind you that Sanimax has a dedicated team to respond to your concerns and to intervene quickly if you report an odour. To do so, we invite you to call the following number: Sanimax – Citizen Services, 514-648-1083.

On behalf of the entire team, we would like to take this opportunity to wish you and all your loved ones, stay safe.
