Americans will cultivate roads with grape brew

The US authorities spend $ 5 billion every year on putting in order the consequences of using road reagents in the winter.

The sodium chloride solution used to combat icing causes great damage to the asphalt and concrete pavement, cannot be decomposed, and can accumulate in soil and groundwater. The concentration of salt in river water is 220 mg per liter for a month, capable of killing 10% of all living organisms in it.

A solution to the problem was proposed by a group of scientists from Washington State University under the direction of Professor Xiangming Shi: adding a fermentation product based on grape meal to a salt solution. Such grape extract acts on the melting of ice, accelerating it at lower temperatures, is not so harmful to the road surface and the environment than the additives used today.

Open technology makes it possible to obtain an additive with similar properties on the basis of any agricultural waste, which makes it economically viable in regions with different agricultural crops.
