Feasibility Study Successfully Approved | Sequoia Supports Taizhou’s 200,000 TPA Waste Organic Solvent Hazardous Waste Project to Secure EIA Approval

Jacob2026-07-08企业新闻/固废资源化/案例展示Views(11)

Recently, Taizhou Huizhide Environmental Technology Co., Ltd.’s 200,000 tons per year waste organic solvent hazardous waste disposal project, for which Nanjing Sequoia Industrial Technology Co., Ltd. provided full-process engineering technical consulting and feasibility study preparation services, has officially obtained the Environmental Impact Report approval issued by Taizhou Municipal Bureau of Ecology and Environment. This marks the full completion of preliminary technical work for this large-scale regional waste organic solvent resource recovery project in Jiangsu Province, adding another benchmark project to Sequoia Industrial’s portfolio in hazardous waste resource utilization and chemical environmental engineering consulting.

Project Overview: Core Hazardous Waste Supporting Project for Taixing Economic Development Zone to Fill Regional Disposal Capacity Gap

Located in Taixing Economic Development Zone, the waste organic solvent hazardous waste disposal project of Taizhou Huizhide Environmental covers a total land area of 90 mu with a total investment of RMB 620 million and a total construction area of 19,044 m². It plans to build supporting facilities including a pretreatment workshop, production process area, standardized hazardous waste warehouses, raw material and finished product tank farms, and a central control room, equipped with nearly 500 sets of core equipment such as extraction towers.

The project is permitted to treat four major categories of industrial waste organic solvents: HW02 pharmaceutical waste solvents, HW06 waste organic solvents, HW11 distillation residues, and HW49 other hazardous wastes. Upon completion, it can comprehensively recycle and utilize 200,000 tons of hazardous waste annually. Primarily serving enterprises within Taixing Fine Chemical Industrial Park, it will also provide waste solvent collection and disposal services for chemical, pharmaceutical and new material enterprises across Jiangsu Province. After reaching full capacity, the project is expected to achieve an annual output value of RMB 650 million, annual tax revenue of RMB 38 million, and create 300 direct jobs, delivering remarkable ecological, economic and social benefits.

As a key circular economy supporting project of Taixing Economic Development Zone, the project adopts advanced industrial waste organic solvent purification and regeneration technologies, adhering to the solid waste management principles of “reduction, resource recovery and harmless treatment”. It is equipped with a full-chain prevention and control system covering waste gas, wastewater, solid waste, soil and groundwater, and environmental risks, including a 150 m³/d comprehensive wastewater treatment station, multiple sets of multi-stage advanced waste gas treatment devices, zoned anti-seepage systems, and a plant-wide emergency accident wastewater tank. All pollutant discharge indicators fully meet stringent local environmental standards of Jiangsu Province, making it a critical underpinning for the green transformation of regional chemical industries.

Professional Empowerment by Sequoia: Full-process Feasibility Study Technical Support to Break Through Key Project Approval Links

Nanjing Sequoia Industrial Technology independently undertook the overall technical scheme preparation for the project’s preliminary feasibility study. Drawing on more than a decade of practical experience in hazardous waste disposal and chemical environmental engineering consulting, its technical team completed comprehensive technical demonstrations by fully aligning with the industrial positioning of Taixing Economic Development Zone, regional hazardous waste generation status, and local environmental supervision policies.

During the feasibility study preparation phase, Sequoia’s technical team focused on four core tasks:

  1. Industrial & Market Demonstration: Sort out the output volume, types and disposal gaps of waste organic solvents generated by fine chemical, pharmaceutical and new material industries in central and southern Jiangsu, verify the rationality of the 200,000 tons per year disposal scale, and clarify the regional service orientation of the project.
  2. Process Route Optimization: Compare multiple purification, separation and regeneration mainstream advanced technologies for waste solvent resource recovery, and finalize an economical, high-efficiency, low-carbon and low-consumption comprehensive utilization process tailored to the mixed HW02/HW06/HW11/HW49 feedstock characteristics of the project.
  3. Systematic Design of Environmental Protection Schemes: Develop a complete pollution control technical system including multi-stage scrubbing + RTO + activated carbon adsorption for waste gas, classified and separated wastewater treatment, zoned anti-seepage, environmental risk prevention and real-time online monitoring. Accurately calculate the total atmospheric and water pollutant emissions of the whole plant to ensure all indicators comply with local DB32 standards for air pollutants, VOCs, odor pollutants and groundwater anti-seepage.
  4. Comprehensive Compliance Verification: Benchmark national and Jiangsu provincial policies covering hazardous waste management, new pollutant control, pollutant discharge permit administration and the “Three Simultaneities” system. Improve management systems such as solid waste ledgers, hazardous waste transfer procedures and environmental emergency response plans, ensuring high consistency between the feasibility study report and EIA and approval requirements, and greatly shortening the project approval cycle.

Backed by a mature consulting system for hazardous waste resource recovery projects, the feasibility study report delivered by Sequoia fully supported the client throughout EIA compilation, park admission review and official approval by ecological and environmental authorities. On February 9, 2026, Taizhou Municipal Bureau of Ecology and Environment formally issued the EIA approval document, approving project construction and specifying full-life-cycle environmental supervision requirements, representing a decisive breakthrough in the project’s preliminary formalities.
