Nickel-iron waste residue belongs to the category of hazardous solid waste, solid waste, referred to as industrial waste. It is a variety of waste residues, dust and other wastes that are prohibited from being discharged into the environment during industrial production. Judging from the characteristics of hazardous waste, it has a huge potential for human health and environmental protection. For example, it may lead to an increase in mortality, or an increase in the incidence of serious diseases, or cause serious harm to human health or the environment when improperly managed. In fact, all integrated enterprises will face the problem of solid waste disposal. However, proper disposal requires a relatively large cost. In addition to fierce competition in the industry, companies will emit in violation of regulations. This is a manifestation of irresponsibility to society.
