Residues diverted from landfill thanks to the CTTÉI

This text is a reproduction of an article by Sarah-Ève Charland published in the online edition of the newspaper Les 2 Rives de Sorel-Tracy. The CTTÉI is at the origin of this initiative. The CTTÉI validated that the physico-chemical properties of the SO2 residue met the acceptance criteria for Agro-100. The two companies were then put in contact.

Rio Tinto Fer et Titane's (RTFT) sulphur dioxide (SO2) recovery plant tailings will be upgraded through an agreement with Agro-100. This is the result of a concerted effort to reduce the environmental footprint and promote sustainable development. The SO2 recovery plant was inaugurated in 2014, but was fully launched in 2015. It reduces SO2 emissions. SO2 emissions are recovered and reacted with hydrated lime.

"This capture process implemented by RTFT produces a product containing residual lime, enriched with sulphur, which has the potential to be an excellent intermediary between a fertilizer and an amendment," believes Stéphane Beaucage, President and CEO of Agro-100. He adds that this direction represents a significant advance in the recovery of residual material to support soil fertilization. The company has filed a notice with the Ministère du Développement durable, de l'Environnement et de la Lutte contre les changements climatiques in order to obtain certification from the Bureau de normalisation du Québec. It hopes to acquire this certification this fall.
Agro-100 is a company specializing in the research, manufacturing and marketing of high-tech agricultural inputs that valorize the use of residual fertilizer materials.
