STM - Society in motion
Not only does it melt snow, but because of it, 1143 trees will be planted!
The STM recently purchased a mobile snow melter. It’s a simple machine, like a huge vat that turns snow into water, while separating it from pollutants and solids. The snow melter is environmentally safe and efficient for getting rid of snow around bus garages. Still, the snow melter runs on diesel and so produces greenhouse gas (GHG) emissions when operated. As a result, the STM decided to join the Projet Carbone Boréal, that enables companies to offset their greenhouse gas emissions by planting trees in areas where natural reforestation is not possible.
The snow melter: an efficient solution
Today, we are pleased to show you a new piece of equipment the STM purchased in 2012: a snow melter.
What does a snow melter do? Basically, its job is to melt the snow that accumulates on STM property. How it works, though, is simple: a loader tractor picks up the snow and dumps it into a huge vat that already has water in it. The water is heated up by a burner and sprayed on the snow, making it melt. Inside the vat is also a drain pan to recover solids, to ensure that only water is channelled back into the wastewater system.
The snow melter can handle between six and eight 10-wheel trucks per hour. The big advantage of this snow melter is that it produces much less noise pollution. It saves us from having to transport several truckloads of snow on the road, so less visual pollution as well. After all, mounds and mounds of dirty snow in a parking lot is not a pretty sight. Its main disadvantage, though, is that it runs on diesel, which produces greenhouse gas emissions. So the STM has joined in the Carbone Boréal project, and will plant trees to offset the GHG emissions from the snow melter.
