Coating assembly ︱Yi He：To interpret the identification policy of hazardous waste in paint packaging drums

Solid waste refers to solid, semi-solid and gaseous substances in containers that have lost their original use value or have not lost their use value but have been abandoned or abandoned in production, living and other activities, as well as items and substances that are included in the management of solid waste according to laws and administrative regulations, he said.

In addition, He Yi listed the details of hazardous waste according to industry sources, taking the manufacturing of paint, ink, pigment and similar products as an example, it will mainly produce wastewater treatment sludge generated in the production of chrome yellow and chrome orange pigments, and wastewater treatment sludge generated in the production of molybdenum lime pigments. At the same time, he Yi also listed the hazardous waste produced by different production processes, taking the solvent-based coating production process as an example, it is easy to produce wastewater treatment sludge, waste packaging, filtering residue and so on.

In the next step, he Yi's organization will first promote the revision of the National Hazardous Waste List, second promote the inclusion of relevant solid waste in the Hazardous Waste Exclusion management List, and third promote conditional exemption of hazardous waste. "All in all, we need to carry out a lot of basic work, especially sampling, analysis and testing, to understand the production process of typical enterprises in the industry, the production of solid waste and its hazardous characteristics, and promote the improvement of laws and regulations. To promote the development of relevant standards and specifications, including national standards and industry standards, such as the technical specifications for cleaning solvent based paint packaging drums, to achieve conditional exemption of hazardous waste under controllable environmental risks, or conditional exemption of utilization." He Yi said.

Be worth what carry is, to effectively reduce the illegal risk enterprise, the ecological environment of solid waste and chemical management technology center as the most authoritative organization of hazardous waste management in China, entrust China coating industry association to organize related businesses involved in the appraisal work as soon as possible, in order to make clear the related enterprise water-based paint production and use of solid waste produced no belong to hazardous waste. In view of the above situation, China coating industry association has been from 2020 to 2021 years for the country's 65 water-based building metope paint and 26 water-borne acrylic emulsion production enterprise has carried out the first identify research work, the niche of the national total output of more than 50% output as a whole, finally to help promote the participation enterprise to be filed in the appropriate jurisdiction, It solves the problem of solid waste treatment and disposal that has been bothering enterprises for a long time. According to the demands of enterprises that have not yet participated, CTU decided to carry out the solid waste assessment of the second batch of water-based building wall coatings and water-based acrylic emulsion production enterprises in China. Stay tuned.
