Winter road services now rely on 'cucumber water' instead of road salt

In Dingolfing, Bavaria, cucumber water from Develey is now being used to clear the roads. Approximately 17,000 tons of cucumbers are processed annually at the Develey plant. After the produce is stored in salt water, the latter is left behind. Previously, the salt water was disposed of through the wastewater treatment plant, but for the second year in a row, the community is now using the brine to make the roads passable again.

The brine works as well as road salt, while still being sustainable. Using cucumber water can save about 1000 tons of road salt and more than 4.9 million liters of water annually.

But how exactly does cucumber water become road salt? After processing the cucumbers, a brine remains. This is filtered to remove any suspended particles and then it is processed. In order to achieve an optimal thawing effect, the salt content of the cucumber water must be increased from approx. 7% to 21% by adding some salt.
