|The former Meloche quarry has been in operation since 1999 and Matrec became the owner in 2016. Upon acquisition by Matrec, an action plan was developed to accelerate site closure and complete facility upgrades to address the odor problems. The implementation of the action plan required the authorization of the Ministère de l’Environnement et de la Lutte contre les changements climatiques du Québec (MELCC). Authorizations were delivered to Matrec at the end of June 2019 and the first stage of the closure works began in August 2019.
It is now official, the Pierrefonds landfill site is now closed. Matrec has fulfilled its commitment by completing all the site closure work. The landfill is now sealed and it will now be possible to give this property a second life.
Over the past two years, Matrec has invested more than $ 10 million to:
All of this new equipment is now in operation and is subject to constant monitoring in order to meet government requirements.
The site is now fully sealed following the installation of the impermeable membrane and cover materials.
The biogas generated by the landfilled materials are collected and directed to the new flare for destruction.
The site was also fully seeded to allow vegetation to grow.

Regulations require landfill owners to closely monitor facilities for 30 years after the site is closed. To this end, the company has created a multi-million dollar fund to monitor the site for years to come.
THE FUTURE OF THE SITE
With the final closure of the landfill site, Matrec has started discussions with the City of Montreal and the Borough of Pierrefonds-Roxboro to assess how the site could serve the community in the future.
