However, unlike at traditional treatment centres, decontaminated soils at the Laval quarry—the first facility
of its kind north of the Island of Montreal—are being
used in situ as fill as part of a long-term remediation process and plan to restore the property and return it to the
community for use in residential, commercial and other
public- and private-sector projects.
The result, according to the two companies behind the
innovative project, is a significant reduction in both truck
traffic and greenhouse gas emissions in Laval and the
Greater Montreal region.
In addition to 5,000 fewer truck trips on the roads, they
estimate that the five-minute drive to carry decontaminated soils from the treatment centre to the rehabilitation
site—a route contained within the relatively safe confines
of the quarry rather than on public roads to sites far
afield—saves the burning (and cost) of 35,000 litres of
diesel fuel a year.

IT’S ABOUT PROCESS
The benefits of Demix decontaminating soil on site include:
5,000 FEWER TRUCK TRIPS on
Greater Montreal roads.
REDUCTION OF GHGS resulting from
the combustion of 35,000 litres of
diesel fuel per year.
TRUCK TRAVEL TIME REDUCED to only five
minutes between the soil treatment centre
and the rehabilitation site.
SIGNIFICANT ACCELERATION of the
rehabilitation of the southern sector
of the Laval quarry (approximately
70 per cent completed).
