During winter, Caso® is good for the environment and can reduce road maintenance costs
A study*, presented at the International Winter Road congress (Poland) in March 2018, draws attention to the effective economic and environmental contribution of using calcium chloride for de-icing.
When spreaded on sodium chloride salt, calcium chloride forms a sticky layer, thereby keeping the salt “trapped” on the road and preventing its migration to environment. Thanks to its other properties, calcium chloride also makes the de-icing solution stay longer on the road. As a result, less salt is needed to keep the road surface safe, which makes it an attractive solution to reducing road maintenance costs as well as reducing environmental impact.
