Update on four amino acid projects 03-19-2024

Summary: CJ Shenyang's arginine project and Quanzhou Adisseo's solid methionine project entered the approval process. Newly-proposed amino acid projects of Dongxiao Biotech and Ningxia Unisplendour were disclosed.

From late Feb. to March, amino acid projects of four enterprises made progress.

CJ (Shenyang) Biotech Co., Ltd. (CJ Shenyang) On 13 March, the local environmental authority said the environmental impact (EI) report of CJ Shenyang's "arginine expansion construction project" would be approved; also, the EI report was published.

Budgeted at USD84,437 (RMB600,000), the project is located in Shenbei New Area, Shenyang City, Liaoning Province. Since the production line equipment is not operating at full capacity during arginine production on the existing lysine line, the company has initiated this project. Upon completion, CJ Shenyang's production capacity for arginine will be expanded from 15,000 t/a to 60,000 t/a.


The arginine production of this project will use glucose, potassium hydroxide, ammonium sulphate and water as the major raw materials. The steps in arginine production process will include raw materials proportioning, bacterial strain culture, main fermentation culture, fermented broth reception, centrifugal separation, resin separation (for preparing ammonia water), concentration, decolourisation, filter press, crystallisation, drying and packaging.

Sinochem Bluestar Adisseo Animal Nutrition Technology (Quanzhou) Co., Ltd. (Quanzhou Adisseo) On 6 March, the EI report of Quanzhou Adisseo's "150,000 t/a solid methionine project" was approved by local environmental authority.

USD694.11 million (RMB4.93 billion) are to be invested in this project, which is situated in Quanhui Petrochemical Industrial Park, Quanzhou City, Fujian Province. After construction is completed, the project will deliver 150,000 t/a of capacity for solid methionine, applying hydantoin method in production.


To date, land acquisition for this project has been completed. Project construction is expected to start in April 2024 and be completed in Feb. 2027. The "150,000 t/a solid methionine project" will only start operating after Sinochem Environment Holdings Co., Ltd.'s "340,000 t/a sulphuric acid (Phase I) project" comes on stream, as this solid methionine project depends on the latter for its operation.

Dongxiao Biotechnology Co., Ltd. (Dongxiao Biotech) On 21 Feb., the EI report (draft for soliciting public opinions) of Dongxiao Biotech's "reconstruction project for high-quality amino acids" was published.

Project overview

  • Type of project: reconstruction and expansion
  • Investment amount: USD14.78 million (RMB105.00 million)
  • Construction site location: Zhudi Industrial Zone, Zhudi District, Xinxing Town, Zhucheng City, Shandong Province
  • Construction details: The original fermentation workshop and extraction workshop in the "30,000 t/a high-end erythritol project" will be reconstructed into fermentation workshop and drying workshop for this "high-end amino acids project". 200 (sets of) existing devices, such as fermenter and evaporator, will be utilised in the project production. 207 (sets of) new devices will be introduced, including granulation bed, sieve for final products, fully automatic packaging machine, etc.
  • Production process and planned capacities: The bacterial strain used in fermentation will be changed. The project production will apply the aerobic fermentation technology and use glucose as a raw material to produce L-Lysine sulphate. Upon completion, the project will enable Dongxiao Biotech to have the capacities of 120,000 t/a for L-Lysine sulphate and 30,000 t/a for high-end erythritol, but the company will switch between these two products in production (rather than two products being produced simultaneously).
  • Ningxia Unisplendour Tianhua Methionine Co., Ltd. (Ningxia Unisplendour) On 6 March, the environmental impact assessment information of Ningxia Unisplendour's "project on tackling key R&D challenges in new methionine production process during pilot-scale experiment, and industrialisation demonstration" was published for the first time.

    Ningxia Unisplendour will spend USD17.48 million (RMB124.22 million) in this new construction project, which is located in Zhongwei Industrial Park, Zhongwei City, Ningxia Hui Autonomous Region. Construction items include production unit devices, warehousing and shipping facilities, utilities, supporting production units and supporting facilities for the whole factory. The project will deliver 10,000 t/a of production capacity for methionine after it is completed and put into operation.
