Proposed at the 2024 Fine Chemical Industry and Park Green Development Conference - Determining the

On May 17-19, the 2024 Fine Chemical Industry and Green Development Conference and the 9th Chemical Industry Hazardous Waste and Waste Salt Treatment and Disposal Forum were held in Yinchuan, Ningxia. The attending experts unanimously agree that chemical waste salt may not necessarily be hazardous waste, but can also be a resource misplaced. When carrying out chemical waste salt treatment, it cannot be recognized as hazardous waste in a one size fits all manner.

It is understood that some chemical industrial parks or enterprises, due to incomplete understanding of the nature of the chemical waste salt they produce, are prone to blindly treating chemical waste salt as hazardous waste when carrying out treatment, resulting in several times the cost of treatment.

Regarding this, colleagues from the Solid Waste and Chemicals Department of the Ministry of Ecology and Environment suggest that enterprises must conduct hazardous waste identification before carrying out chemical waste salt treatment; The competent department should not classify hazardous waste as hazardous waste in a one size fits all manner during management. He also stated that in the future, the Ministry of Ecology and Environment will accelerate the development of pollution control technical specifications for solid waste utilization and disposal, accelerate the construction of regional hazardous waste disposal centers, and other measures to help solid waste and hazardous waste find suitable "good places" as soon as possible.

Comrades from the Energy Conservation and Comprehensive Utilization Department of the Ministry of Industry and Information Technology stated that the background of new industrialization is green, and green, low-carbon, and sustainable development is a more economical high-end development path. The petrochemical industry should actively guide enterprises and parks to fully implement a new round of green and low-carbon technology transformation, accelerate the optimization and adjustment of traditional industry product structure, use structure, raw material structure, and process reengineering, and continuously improve the international competitiveness of China's petrochemical industry.

"Chemical waste salt mainly comes from industries such as coal chemical, dyes, pesticides, pharmaceutical intermediates, and new chemical materials. Promoting the coupling of high concentration saline wastewater or waste salt residue with caustic soda facilities is one of the effective ways to achieve the resource utilization of chemical waste salt," said Li Bin, Vice President of the China Petroleum and Chemical Industry Federation.

Li Bin also pointed out that the comprehensive utilization of solid waste should accelerate the construction of a circular development system. The petroleum and chemical industry should accelerate the construction of a circular economy system from three levels: small enterprise circulation, intra park circulation, and social circulation, in order to improve the degree of industrial linkage and the efficiency of circular linkage. At the same time, the petrochemical industry can also explore resource recycling links with related industries such as metallurgy, building materials, and non-ferrous metals, allowing solid waste to be "consumed and squeezed clean".

Zheng Baoshan, Vice President and Professor level Senior Engineer of the Institute of Petroleum and Chemical Industry Planning, believes that the demand for chlorine in the fine chlorine industry has characteristics such as relatively small scale, nearby supply, stable sources, and controllable costs. Applying chemical waste salt to the fine chlorine industry will have great market development space. He also mentioned that the Guiding Catalogue for Industrial Structure Adjustment has guiding significance for the utilization of chemical waste salt resources, and relevant enterprises should seize development opportunities.

The conference released the 2023 Catalogue of Key Green and Low Carbon Supporting Technologies for the Petroleum and Chemical Industry; The environmental innovation "unveiling and leading" activity of Ningdong Energy and Chemical Base was also launched at the same time. The conference also held forums on green, low-carbon development in the fine chemical industry and green, low-carbon, and high-quality development in chemical parks.

This meeting is guided by the Petrochemical Federation, hosted by the China Chemical Environmental Protection Association, and hosted by the Ningdong Energy and Chemical Base
