Beijing Jinyu Beishui Environmental Protection Technology Co., Ltd., located in Daxing District, Beijing, is a high-tech enterprise under the Jinyu Group specializing in the resource utilization and co-processing of industrial solid waste. It belongs to Jinyu’s environmental protection business segment and possesses an annual hazardous waste co-processing capacity of 150,000 tons via cement kilns, making it a leading environmental technology service provider in North China with comprehensive qualifications and scale. The company’s core businesses focus on five technical pathways: (1) harmless treatment of hazardous waste (covering 12 major categories and 44 subcategories, including HW02, HW03, and HW04); (2) resource utilization of fly ash from municipal solid waste incineration; (3) remediation of contaminated soil; (4) volume reduction of municipal sewage sludge; and (5) high-value utilization of industrial by-product gypsum. Its clients include healthcare institutions, iron-and-steel industrial parks, new area infrastructure projects, and chemical-related industries such as electronics and automobile manufacturing. Its core capabilities span the entire technical closed loop of “pre-treatment—precise waste blending—high-temperature destruction inside kilns—resource reuse of kiln dust.” Leveraging its self-developed intelligent blending system (software copyright registration number: 2024SR0872156), the company achieves dynamic identification of waste composition and real-time optimization of feeding parameters; dioxin emissions remain stably below 0.05 ng TEQ/m³. As of the end of 2025, the company holds 23 authorized invention patents and 47 utility model patents, and has led or participated in developing six national and association standards, including the “Guidelines for Review of Operating Licenses for Hazardous Waste Co-processing in Cement Kilns” (HJ 1317–2023). The company holds the hazardous waste co-processing operating license for cement kilns issued by the Ministry of Ecology and Environment (License No.: Jing Huan Wei Xu Zi [2023] 027), Grade I qualification for environmental engineering contracting, ISO 9001/14001/45001 integrated management system certifications, the “Work Safety Production License,” and the “Pollutant Discharge Permit” (Registration No.: 91110000748847228L001V). Representative projects include: four consecutive years of emergency co-processing services for medical waste generated by Beijing municipal healthcare institutions (cumulative volume exceeding 18,000 tons); thermal desorption plus co-solidification treatment of 126,000 m³ of heavy-metal-contaminated soil at Shougang Industrial Park; a 300-ton-per-day municipal sewage sludge EPC project for the initial development zone of Xiong’an New Area; and full-chain hazardous waste services provided to 27 key enterprises, including BOE Technology Group and Mercedes-Benz Beijing Plant. Its business covers Beijing, Tianjin, Hebei, Shanxi, and Inner Mongolia provinces/regions. Through Jinyu Group’s international cooperation platform, the company has delivered feasibility technical consultancy on cement kiln co-processing to the Smederevo Steel Mill in Serbia; however, publicly available information does not indicate independent engagement in overseas EPC projects or equipment exports.
