As the negative effects of chlorinated snow-melting agents are more and more obvious, some non-chlorinated snow-melting agents (such as magnesium calcium acetate) are also being developed. At the same time, some methods without snow-melting agents (such as mechanical snow removal and thermal snow removal) have also been developed and applied. However, in terms of snow melting efficiency, speed, convenience and cost-effectiveness, chlorine salt snow melting agents are still difficult to replace at present.

According to the research of the Department of Public and Environmental Engineering of Maarte University, the accidental injury accident can be reduced by 88.3% by sprinkling chlorine salt in snowy days, and the chlorine salt snow melting agent is indeed powerful and contributes a lot. "Ice-melting salt" has shown advantages in ensuring snowy city, smooth road traffic and public safety. Although it has serious negative effects at the same time, chlorine salt snow-melting agents still need to be used continuously. It is reported that the annual consumption of "deicing salt" in the United States can reach 10 million tons, accounting for 1/3 of the total salt production; The annual consumption in Canada is 4-5 million tons. In North America, Northern Europe and other places, "deicing salt" products have become a certain scale industry.
