A Dutch trial project is investigating whether road salt can be replaced by grass juice. Grass juice would be a more environmentally-friendly alternative to salt. At ZOUTMAN, we are 100% supportive of sustainable innovations. That is why ZOUTMAN resolutely opts for sea salt to be used on roads. Salt extraction from the sea is one of the world’s oldest traditions and requires nothing more than the sun, sea and wind. You can’t get any more ecological.
