　　Jiangxi Silinco Co., Ltd. was originally located at No. 1299 Yuping West Street, Nanchang Economic and Technological Development Zone. Due to the replanning and adjustment of construction land in the zone, the company relocated in 2013 to the Baishui Lake Industrial Park, Nanchang Economic and Technological Development Zone, Jiangxi Province. After the relocation and expansion, the production scale is 1,500 t/a of MMT, 3,000 t/a of MCPD (1,600 t/a for self-use), 5,000 t/a of high-purity manganese chloride (1,200 t/a for self-use), 40,000 t/a of diesel anti-wear additive, 20,000 t/a of cetane number improver, 50,000 t/a of sec-butyl acetate, 2,000 t/a of ultra-high-purity nickel nitrate and 5,000 t/a of refining catalyst. The project was approved by the Nanchang Municipal Environmental Protection Bureau on September 4, 2013 (Honghuan Approval No. 242). At present, the 5,000 t/a high-purity manganese chloride, 1,500 t/a methylcyclopentadienyl manganese tricarbonyl (600 t/a carbon monoxide (MMT raw material)) and 20,000 t/a cetane number improver have passed the self-environmental protection completion acceptance; the other products will no longer be built.
　　Complaints and administrative penalties received by the enterprise in the past five years: on February 19, 2019, for “discharging atmospheric pollutants in excess of standards”, the Nanchang Municipal Ecological Environment Bureau imposed a penalty under “Honghuan Xingfa [2019] No. 12” with a fine, and the penalty has been completed; on August 6, 2020, for “total manganese in the total wastewater outlet exceeding the standard”, the Nanchang Municipal Ecological Environment Bureau imposed a penalty under “Honghuan Xingfa No. 18” with a fine, and a hearing is currently being applied for and pending determination.
