Salt is cheap and abundant. It also serves to combat ice on roads. But according to studies in the US and the UK, salt eats bridges and roads. In the UK it is expected that salt will cause losses of 800 million pounds over the next 15 years.

Thus, some companies have begun to investigate substitute products. “BP Chemicals” has just presented an antifreeze product. This substance is made up of calcium and magnesium acetate and is 20 times more expensive than salt. This cost is very low if the damage caused by salt is taken into account.
