Ningxia Zhongke’s Bio-fermentation Products Project

Posted on by

On 20 Jun., Ningxia Zhongke Biomaterials Co., Ltd. (Ningxia Zhongke) publicized the environmental impact report for its 119,000 t/a bio-fermentation products project.

 

Project overview

  • Nature: Technological renovation
  • Location: Shizuishan Economic and Technological Development Zone, Ningxia Hui Autonomous Region.
  • Total investment: USD13.9 million (RMB100.089 million)
  • Construction scale:
    • 18,000 t/a of Long chain Dicarboxylic Acid Flexible Production Line: Leverage existing fermentation tanks and extraction lines, construct a new extraction line to produce 10,000 t/a of sebacic acid, 1,000 t/a of undecanedioic acid, 2,000 t/a of tridecanedioic acid, 2,000 t/a of tetradecanedioic acid, and 1,000 t/a of each of pentadecanedioic acid, hexadecanedioic acid, and octadecanedioic acid.
    • 5,100 t/a of Bio fermented Functional Products Flexible Production Line:
      • Use existing fermentation tanks and extraction lines to build a new extraction line for producing 800 t/a of D-chiro-inositol, 300 t/a of coenzyme Q10, and 4,000 t/a of DHA algal oil.
    • 63,000 t/a of Bio food Flexible Production Line:
      • Utilize existing fermentation tanks and upgrade extraction lines to achieve a capacity of 3,000 t/a of calcium propionate and 60,000 t/a of L-malic acid.
    • 24,800 t/a of Amino Acid Products Flexible Production Line:
      • Use existing fermentation tanks and upgrade extraction lines to produce 3,000 t/a of L-arginine, 3,000 t/a of L-isoleucine, 5,000 t/a of L-tryptophan, 5,000 t/a of L-methionine, 5,000 t/a of L-threonine, 300 t/a of L-hydroxyproline, 500 t/a of L-histidine hydrochloride, 1,000 t/a of L-proline, 1,000 t/a of L-cysteine, and 1,000 t/a of glycine.
    • Production Process:
      • The process involves three main stages: seed cultivation, fermentation, and extraction.
      • Fermentation broth is produced by fermenting strains using glucose, yeast extract, and nitrogen-containing materials.
      • The broth is then treated through acidification, ceramic membrane filtration, crystallization, centrifugation, and drying to obtain the final products.
    • Labor quota: 102 new employees.
    • Working system: Four-shift three-rotation system, 360 working days totaling 8,640 hours per year.
    • Construction period: about 9 months (To start in Jul. 2025)
