On 30 Jan., the completion environmental-protection acceptance monitoring report for Heilongjiang Nuopu Biological Technology Co., Ltd. (Heilongjiang Nuopu) high-quality amino acid industrialization and capacity expansion project was published on an environmental platform.

Project overview

• Nature: Expansion & retrofit
• Location: Chemical Park, Fujin City, Heilongjiang Province
• Total investment: USD21.5 million (RMB150 million)
• Construction content:
  • Build one high-quality amino acid line producing leucine (95%), isoleucine (95%) and citrulline (95%); one line for processing by-products such as wet bacterial protein.
  • Carry out capacity expansion and efficiency upgrades on the existing production lines by purchasing saccharification, fermentation, extraction and utility equipment; at the same time, reassign the two existing lines in the separation/extraction shop to produce leucine (90%), isoleucine (90%) and L-tryptophan (90%).
• Product plan: 2,940 t/a of Leucine (90%), 8,820 t/a of Isoleucine (90%), 300 t/a of L-tryptophan (90%), 2,700 t/a of leucine (95%), 1,500 t/a of isoleucine (95%), 800 t/a of citrulline (95%), 16,100 t/a of by-product bacterial protein
• Key raw materials: 100,371 t/a of starch slurry, 865 t/a of arginine, etc.
• Process routes:
  • Use starch slurry to make leucine (90%) and isoleucine (90%); further refine to leucine (95%) and isoleucine (95%);
  • Purchase arginine and other inputs to produce citrulline (95%).
• Labor quota: no additional employees
• Working system: three 8hr shifts per day, 330 working days totaling 7,920 hours per year
• Progress:
  • Approval of EI report: Apr. 2025
  • Started construction: May 2025
  • Completion: Oct. 2025
  • On-site acceptance monitoring: 27–28 Nov., 2025

Jiangsu Baoshen Longcheng Pharmaceutical Co., Ltd. (Baoshen Longcheng) plans to invest USD8.4 million (RMB60 million) in a 1,920 t/a of food-grade amino acid project comprising 12 products: 100 t/a of DL-homocysteine thiolactone hydrochloride, 1,020 t/a of N-acetyl-L-cysteine, 100 t/a of N-acetyl-L-thioproline, 100 t/a of N-acetyl-L-tyrosine, 50 t/a of N-acetyl-(D)L-leucine, 100 t/a of L-ornithine hydrochloride. 50 t/a of S-hydroxymethyl-L-cysteine, 100 t/a of L-cysteine (base), 100 t/a of L-pyroglutamic acid, 50 t/a of L-cysteine hydrochloride anhydrous, 100 t/a of L-lysine hydrochloride and 50 t/a of L-ornithine aspartate.

Due to market conditions, the project will be built in two phases. On 10 Sept., the local Ecology & Environment Bureau approved the EI report for Phase I and released the decision for public inspection.

Overview of Phase I

• Nature: Retrofitting
• Location: Guannan County, Lianyungang City, Jiangsu Province
• Total investment: USD5.6 million (RMB40 million), of which USD0.14 million (RMB 1 million) is for environmental protection
• Product plan:
  • 1,020 t/a of N-acetyl-L-cysteine
  • 100 t/a of N-acetyl-L-tyrosine
  • 100 t/a of L-ornithine hydrochloride
  • 50 t/a of S-hydroxymethyl-L-cysteine
  • 100 t/a of L-cysteine (base)
  • 50 t/a of L-cysteine hydrochloride anhydrous
  • 100 t/a of L-lysine hydrochloride
• Key raw materials: L-cystine, L-tyrosine, L-arginine, L-lysine HCl, acetic anhydride, etc.
• Labor quota: No additional staff (Relying on existing workforce)
• Working system: three 8hr shifts per day, 300 working days per year
• Construction period: 3 months
