Today salt extraction and production is a simple process, and salt is a cheap commodity. The low pricing of the final product drive the producers to lower their costs to gain profit, so coal usage for energy is very common for salt production.
Selkur, without using any heavy machines, exempts its 99.7% pure salt from harmful materials to the environment and the human health, such as coal or dynamit.
Selkur, with a high consciousness of environment sustainability, consumes green energy sources such as electricity and natural gas, regardless of higher costs.
