• Year 1999

              Jiangxi Keyuan Biotech Co., Ltd. (“JXKY” for short), the shareholder of the Company, was incorporated, and started to independently research and develop the production technology of chiral lactic acid.
            • Year 2000

              JXKY and Musashino Institute of Chemistry (one of world major three lactic acid manufacturers) established a Sino-Japanese joint venture of Jiangxi Musashino Biochemical Co., Ltd., starting the industrialization of ten-thousand-ton-level high-purity chiral lactic acid.
            • Year 2000-2008

              Over the eight years of joint venture, the Chinese side, as major operation team, has organized and implemented the design, construction and operation of ten-thousand-ton-level production line, and the product quality has reached internationally leading level, making it become a famous lactic acid brand in China. In order to develop biodegradable materials, the Chinese side quit the joint venture in 2008, and then independently developed lactic acid-PLA industry.
            • Year 2008
