Shanghai Chemical Industry Park Shengda Waste Treatment Co., Ltd. is a professional environmental protection service enterprise approved by the Shanghai Municipal Ecological Environment Bureau and holding a Hazardous Waste Operation Permit. It serves as a key supporting unit of the national-level Shanghai Chemical Industry Park’s circular economy system. The company specializes in the collection, storage, treatment, and resource recovery of hazardous waste. Its permitted operations cover seven major categories and 32 subcategories of hazardous waste, including HW02 (pharmaceutical waste), HW06 (waste organic solvents and wastes containing organic solvents), HW08 (waste mineral oil and wastes containing mineral oil), HW11 (residues from refined distillation), HW12 (dye and paint waste), HW13 (organic resin waste), and HW49 (other wastes). The company’s annual permitted treatment capacity totals 85,000 tons, with treatment methods encompassing physicochemical treatment, high-temperature incineration, and secure landfilling. Core facilities include: a 30,000-ton-per-year rotary kiln incineration system compliant with GB 18484–2020; a combined physicochemical and biochemical treatment system for high-concentration wastewater; and a standardized 12,000-square-meter interim storage warehouse for hazardous waste (operating per GB 18597–2023). The company holds Hazardous Waste Operation Permit No. Hu Huan Wei Fei Jing Zi [2023] No. 087, has achieved certification under ISO 9001, ISO 14001, and ISO 45001 (Certificate No.: 00122Q41234R1M), and has been selected for Shanghai Municipality’s “Green Manufacturing System Construction Demonstration Unit” cultivation program. Technically, the company participated in drafting the “Shanghai Chemical Park Hazardous Waste Collaborative Disposal Technical Guidelines (Trial)” and holds three invention patents—including the “High-Efficiency Dehalogenation Incineration Process for Halogenated Organic Waste Liquids”—and seven utility model patents. Dioxin data from its incineration flue gas are transmitted in real time to the Shanghai Municipal Ecological Environment Big Data Platform, and the company has passed unannounced inspections conducted by the Ministry of Ecology and Environment for five consecutive years. It provides long-term services to multinational chemical enterprises such as BASF, Bayer, Covestro, Huntsman, and Mitsui Chemicals, as well as large domestic petrochemical, pharmaceutical, and electronic materials enterprises. Its business covers Shanghai Municipality, Jiangsu Province, and Zhejiang Province, offering integrated environmental solutions—from hazardous waste generation declaration, manifest-based transportation, classified pretreatment, compliant disposal, to resource recovery—and welcomes end-to-end collaboration on hazardous waste management across the chemical, pharmaceutical, and new materials industries.
