I would like to ask: Is the salt generated through evaporation in production considered hazardous waste? What standards are used to determine this? Salt is very white

The waste salt produced by the evaporation and crystallization of concentrated brine is a type of hazardous waste with multiple components; its main waste categories are HW35 waste alkalis and HW45 waste containing organic halides. Depending on the production process, it may also contain heavy metals, catalysts, and other types of waste.

So, how should it be tested and identified?

Is there any salt production by evaporation in China that is not considered hazardous waste?

The chemical composition is tested in the laboratory, and then compared with the **List of Hazardous Wastes**.

@zb030121eric: Is there any evaporation salt production in China that is not classified as hazardous waste? I can’t guarantee it. They are generally stored in hazardous waste sites (as shown in the figure). Responsible companies are taking measures to reduce waste.
