With the Clewat solution, a significant amount of harmful substances can be removed cost-effectively from the snow and, if necessary, lead the rest of it to the water treatment plant via the sewer system.
The snow collected from cities ends up as impurities in the water.
Only in Helsinki, in Hernesaari in the winter of 2019, 20,000 loads heavy untreated snow was dumped into the sea. With the snow, several thousand kilos of rubbish and over fifty million microplastic particles reach the sea during the winter.
Defrosting snow with old methods accelerates climate change and rubbish on our waterways.
We can do better. Already today.
There is a better solution to this problem: Clewat’s snow cleaning and melting system.
With the Clewat solution, a significant amount of harmful substances can be removed cost-effectively from the snow and, if necessary, lead the rest of it to the water treatment plant via the sewer system. Melting snow uses the power of flowing water and seawater temperature or waste heat from the district heating network and renewable energy. The snow and water passing through the process is filtered and the waste is collected.
The whole process is done without the use of carbon emissions and the use of fossil fuels, with the exception of emissions from the transport of snow. However, Clewat model can also shorten snow transport distances and thus reduce the environmental impact of travel.
A better and more cost-effective technology is, therefore, exist.
