According to the relevant regulations on the approval process for environmental impact assessment of construction projects, our bureau intends to review the environmental impact assessment documents of Guangdong Huanyuan Environmental Protection Technology Co., Ltd.'s environmental protection, energy conservation and resource comprehensive utilization project. In order to reflect the principle of openness and fairness, and strengthen public participation, the basic information of the environmental impact assessment documents of the project is now publicly announced for a period of 5 working days. If you have any opinions, please send a letter or call to our bureau during the public announcement period. Contact address: Building 7, Citizen Service Center, No. 31 Sanxin North Road, Jiangbei, Huizhou City, postal code 516001 Contact phone number: 0752-2167968 Hearing notice: According to the Administrative Licensing Law of the People's Republic of China, within five working days from the date of public announcement, applicants and interested parties may apply for a hearing on the approval decision of the environmental impact assessment documents for the following construction projects. Project Name: Guangdong Huanyuan Environmental Protection Technology Co., Ltd. Environmental Protection, Energy Conservation and Resource Comprehensive Utilization Project Construction Unit: Guangdong Huanyuan Environmental Protection Technology Co., Ltd. Construction Location: Tangkou Group, Shanglong Group, Chencun Village, Huzhen Town, Boluo County, Huizhou City Environmental Impact Assessment Institution: Guangzhou Guohuan Environmental Protection Technology Development Co., Ltd. Project Overview: Guangdong Huanyuan Environmental Protection Technology Co., Ltd. (formerly known as Huizhou Xinlong Environmental Protection Technology Co., Ltd.) is located in Tangkou Group, Shanglong Group, Chencun Village, Huzhen Town, Boluo County, Huizhou City, mainly engaged in the comprehensive utilization of hazardous waste such as heavy metal sludge. Approved for environmental impact assessment in 2012. In 2017, it passed the environmental protection inspection and obtained the "Hazardous Waste Operation License" issued by the former Guangdong Provincial Environmental Protection Bureau, with a business scale of 40000 tons per year. In 2023, the Guangdong Province Hazardous Waste Operation License will be renewed, and the approved treatment categories and scales are: collection, storage, and utilization of surface treatment waste (HW17 category, limited to tank slag and sludge only) of 14000 tons per year, surface treatment waste (HW17 category, limited to tin removal waste tank solution only) of 4000 tons per year, copper containing waste (HW22 category, limited to tank slag and sludge only) of 10000 tons per year, and copper containing waste (HW22 category, excluding tank slag and sludge) of 8000 tons per year; Nickel containing waste (HW46 category, solid only) 4000 tons/year, totaling 40000 tons/year. This project plans to transform the blast melting furnace into an oxygen enriched side blowing melting furnace within the existing project land area, while adding one heavy metal sludge wet production line and increasing the scale of the copper containing etching waste liquid production line. The annual comprehensive utilization of hazardous waste in the heavy metal sludge pyrometallurgical production line before and after the construction of this project remains unchanged at 28000 tons, including 14000t/a of HW17 solid surface treatment waste, 10000t/a of HW22 solid copper containing waste, and 4000t/a of HW46 solid nickel containing waste; The wet process production line for heavy metal sludge is a newly added production line with a processing capacity of 20000 tons per year, mainly for HW17 surface treatment waste; The processing scale of the copper etching waste liquid production line has increased by 28000 tons per year, and the processing category remains unchanged, mainly HW22 copper containing waste; The processing scale and category of the tin stripping waste liquid production line remain unchanged at 4000 tons per year, mainly consisting of HW17 surface treatment waste.
