SÉMECS serves the Regional County Municipalities of Marguerite-D’Youville, La Vallée-du-Richelieu, and Rouville, covering 27 municipalities with approximately 700,000 residents, as well as a wide range of institutions, businesses, and industries.
Its mission is to convert organic waste into renewable energy, reduce the amount of waste sent to landfills, and limit greenhouse gas emissions. gbi supported the project at every stage: preparing and monitoring the ministerial authorization request, modeling and controlling odors, and coordinating with all stakeholders to combine innovation with environmental compliance.
Tackling complex technical challenges
This project stands out for its complexity and innovation. Multiple stakeholders, diverse regulations, and an emerging biomethanization technology required precise coordination and advanced technical expertise.
At the core of the mandate, the atmospheric dispersion modeling carried out by gbi played a decisive role in the success of the project. This in-depth analysis made it possible to accurately assess the spread of odorous and pollutant emissions generated by the biomethanization process, taking into account local weather conditions and site characteristics. By relying on advanced simulation tools and a thorough understanding of the MELCC guidelines, gbi was able to recommend tailored mitigation measures, ensuring optimal and environmentally responsible operation. This rigorous work helped guarantee the project’s compliance with the highest environmental standards while supporting SÉMECS’s sustainable and innovative vision.
tonnes of organic waste that is treated in an environmentally responsible manner annually
millions of cubic meters of biogas are recovered and used for ethanol production
tonnes of organic waste per year will be diverted from landfills thanks to the facility’s treatment capacity
