The composting platform of the Centre régional de traitement de la matière organique (CRTMO) has just reached a new stage with the realization of its first compost screening. The compost is the result of the decomposition of organic waste received from the City of Thetford Mines and surrounding municipalities’ brown bin collection, as well as bulk green residues brought to the region’s eco centres.

In fact, nearly 500 cubic metres of this mixture was passed through a rotary screen to eliminate elements that would not have been completely composted. This refined compost is now ready to be recycled. To do so, it will be used as fertile soil to revegetate the former Black Lake mine site and eventually, the former National Mine. As a result, nature will gradually come back to life in a few years by a diversified fauna.

“The success of this screening phase is a source of pride for our compost bin collection team and the public. They have contributed to this magnificent result, which is beneficial to the environment,” said Mélanie Brousseau, Vice-President and General Manager of Sanitaire Fortier.

“This is a great example of a collective regional project which, with all the necessary facilities and equipment, allows us to ensure a second life for food and plant waste, thus respecting the criteria of the green, circular and social economy,” said Simon Naylor, Vice-President Administration and Development of Viridis environment and President of the CRTMO.

The CTRMO is in line with the environmental objectives set out in the Québec Residual Materials Management Policy, which aims to encourage more environmentally friendly societal behaviour and better practices in the consumption and sound management of residual materials.

Combining their fields of expertise in environmental engineering and waste management and recovery, Viridis environnement and Sanitaire Fortier are the co-partners of this facility inaugurated in 2019. For more information on this composting site:
