Purification facilities

 

Leaf Processing and Purification

Our extraction and refining operations consist of two components: primary processing of stevia leaf into intermediate stevia extract; and purification into final high-grade stevia extract products. All of our extraction and refining operations are located in China and we have four wholly owned subsidiaries in China that undertake the primary processing and purification operations.

Purification

We have current production capacity of 1,000 metric tons of high-grade stevia (RA 80) or 500 MT of rebiana (RA 97) at our Qingdao facility (Runde) and we have current production capacity of 2,000 MT of high-grade stevia (RA 80) or 1,000 MT of rebiana (RA 97) at our other Qingdao facility (Runhao). We own or have access to certain proprietary technology for producing high-grade stevia extract.

Purification of intermediate stevia extract to final product generally follows two steps:

  • the primary extract is dissolved in a water-ethanol solvent mixture and further processed by filtration, crystallization, and centrifugation steps; and
  • the resulting preparation of crystals is rinsed with food grade ethanol and vacuum-dried to yield the final high-grade Rebaudioside A product.

In May 2009 we entered into a long term investment agreement with the Qingdao Export Refine Management Committee.  Pursuant to this investment agreement, a total area of 215 acres of land will be made available to our subsidiary Runhao.  The first phase of the development occupies 60 acres of land where a secondary processing facility with capacity of 2,000 metric tons of high-grade stevia (RA 80) or 1,000 metric tons of rebiana (RA 97) or 2,000 metric tons of BlendSureTM was constructed and started operations in December 2009. 

Runhao

Qingdao City

In May 2009, the company entered into a long term investment agreement with the Qingdao Export Refine Management Committee for land and construction of a state-of-the-art secondary stevia processing plant.  In December 2009, phase one of Runhao was completed and went into full operation 2Q 2011.  The facility has the current capability of producing up to 2,000 metric tons of high-grade RebPure RA80 or an equivalent 1,000 metric tons of RebPure RA97.  The Runhao secondary processing facility takes the lower grade intermediate stevia extracts produced at our primary extraction facilities and refines them to high-purity.

This incorporates our two-step patented extraction process:

Step 1
The primary stevia extract is dissolved in grain neutral spirits and then further processed through filtration, crystallization, and centrifugation; and

Step 2
The resulting crystals are rinsed and vacuum-dried to yield the final high-grade Rebaudioside A product.

 

Highlights

  • State-of-the-art high-purity extraction facility
  • High production capacity of 2,000 metric tons of high-grade stevia (RA80) or an equivalent 1,000 metric tons of rebiana (RA97)
  • Additional land available for expansion of production facilities as required to meet long-term capacity growth
  • Easy access to ship, air, and rail transportation
  • Utilizes certain proprietary technology for producing high-grade stevia extract



   
 
     

Runde

Qingdao City

December 2006, GLG acquired Qingdao Runde Biotechnology Company Limited ("Runde"), a leading manufacturer of high-grade stevia.  Runde possesses the technology to extract and refine to levels of RA97+.

 

 

Highlights

  • History of strong revenue growth
  • Technology to extract and refine stevia up to levels of RA97+
  • Strategically positioned to capitalize on the rapid increases in demand expected as the market for stevia continues to develop
  • Current capacity of 1,000 metric tons of RA80 and 500 metric tons of RA97
