Salt was first utilized for ice control and deicing during the 1930's and during the 60's, it became the most widely used deicing agent due to its efficiency. In the modern world, salt has become an important part for combating icy roads and pavement. It provides mobility for people walking on the sidewalks are motorists driving in the highways. But above all, it can help prevent any accidents that may be the result of an icy pavement. And while drivers have the sole responsibility of driving extra carefully especially during winter season, the roads can be very hazardous without salt. Today, solar salt is widely used for deicing pavements and sidewalks and it has been very effective in performing its job even if there are some people who contradicts the over use of solar salt and its effect to the environment.
Primarily, solar salt is used as a deicer simply because it is widely available, cost effective, and safe to use. This is far cheaper to use and poses no significant harmful effects to the environment when used in controlled conditions as compared to other deicing agents that are chemically based and can be toxic for humans and the environment in general. solar salt, which is basically evaporated from the sea water using the power of the sun, is more cost effective compared to rock salt which has to be mined from the earth. And in today's highly mobile world, it is important to get rid of or control hazardous conditions usually created by ice and snow in order to keep the roads, sidewalks, and pavements safe. Salt can also be used alone when there is no too much snow or ice in the pavement but after a snowstorm, this is used in combination with snowplows to remove the ice from the middle of the road and allow it melt quickly using salt.
When solar salt is put on ice or snow, the combination will result to a brine solution which has a much lower freezing point compared to the surrounding ice and snow without salt. More often than not, solar salt is commonly used as deicing agent simply because it is available worldwide, easy to apply and store, non-toxic, harmless to the skin or clothing, very affordable, and when solar salt is used properly, it can also be deemed as harmless to the environment. This can also be very effective when applied earlier before a snow storm because it can help create a barrier between the pavement and the ice that will soon be accumulated on the surface.
As the most cost effective deicing agent, solar salt ice melt aside from rock salt. A lot of companies offer several types of deicing solutions but none of them are as effective yet affordable as rock salt. And since this is all natural, it has no adverse effects to the environment as long as the deicing process is carefully implemented and the proper storage is followed.
