Total investment in new materials: 530 million yuan! Jiangsu’s project for the recycling of 334,000 tons of NMP waste liquid is set to be approved Author: Hua Xiaobei Source: Coal Chemical Industry Information Network Views: 466 Update date: October 9, 2025 On September 26, the Data Bureau of Nantong City issued a notice stating that the environmental impact assessment report for Jiangsu Shenghe New Materials Technology Co., Ltd.’s project aimed at the comprehensive recycling of 334,000 tons per year of NMP waste liquid and the production of 20,000 tons of conductive paste per year is set to be approved. Project Name: Comprehensive Utilization of 334,000 tons/year of NMP Waste Liquids and Production of 20,000 tons/year of Conductive Paste ； Construction location: No. 9, Kangye Road, Changjiang Town, Rugao City (Rugao Port Industrial Park) ； Construction unit: Jiangsu Shenghe New Materials Technology Co., Ltd ； Total investment amount: 530 million yuan, of which 18 million yuan is invested in environmental protection, accounting for 3.4% of the total investment ； Construction period: 24 months, with Phase 1 running from September 2025 to August 2026, and Phase 2 from September 2026 to August 2027. Environmental impact assessment agency: Nanjing Yuanheng Environmental Research Institute Co., Ltd ； Project overview: Based on the conclusions of the project’s environmental impact assessment, from an environmental protection perspective alone, it is feasible to construct the project at the proposed location, provided that the enterprise strictly implements all the ecological and environmental protection measures as well as environmental risk prevention measures outlined in the report, and that all types of pollutants are discharged within acceptable levels without exceeding the established control limits. The project is located at No. 9 Kangye Road, Changjiang Town, Rugao City, Nantong (Rugao Port Industrial Park), where new factory buildings and auxiliary facilities are being constructed. The total construction area is 16,760.15 square meters. Approximately 400 units of equipment such as distillation towers, storage tanks, condensers, pumps, and sand mills will be purchased ； Facilities for supporting operations will be constructed, including structures such as circulating water stations, tank areas, hazardous waste warehouses, and sewage treatment plants. This will enable the processing of 334,000 tons of NMP waste liquid per year, as well as the production of 300,000 tons of recycled NMP per year (of which 18,750 tons of the recycled NMP will be used as raw material for the production of carbon nanotube conductive pastes within the factory, while the remaining 281,250 tons will be sold directly as a product). The production capacity for carbon nanotube conductive pastes will be 20,000 tons per year.
