Primary Processing 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.

Primary Processing Operations

Our primary processing operations involve the conversion of raw stevia leaf to intermediate-grade stevia extract (RA 60% pure). This generally follows the following process: (i) stevia leaves are dried, crushed and extracted with water; (ii) the resin is washed with food grade ethanol to release the glycosides; and (iii) the glycosides are concentrated with an absorption resin, and dried to formulate the primary extract.

In order to meet our customer’s requirements and expected market demand, we have invested in the construction of two facilities to expand our manufacturing capabilities in 2008.  Operations commenced in early 2009 at our two facilities in Dongtai and Mingguang, which increased our total potential raw leaf processing capacity to 41,000 MT. 

We have received two key patents in 2010 in China to protect the intellectual property developed at our primary processing facilities involving water purification and stevia extract soaking technology. 

In addition to primary processing capacity and warehousing, our facilities in Dongtai and Mingguang include a significant research and development facility, office buildings and supporting infrastructure (water treatment facilities, etc.). 

Runyang

Dongtai City

In August 2007, the company broke ground on its Dongtai Runyang Stevia High Tech Company Limited ("Runyang") processing facility in the Jiangsu Province city of Dongtai. The agricultural region around Dongtai is one of the largest and best stevia growing areas in China. The construction of Runyang was part of an agreement between GLG Life Tech Corporation and local governments to exclusively grow and manufacture stevia in these regions. This agreement is for 10 years. Phase one construction at Runyang was completed in December 2008. Utilizing new and innovative technology developed by the company's engineers, Runyang was able to nearly double its anticipated capacity and is currently able to process 18,000 metric tons of raw leaf (original plans anticipated 10,000 metric tons).

Runhai

Mingguang

In August 2007, the company broke ground on Chuzhou Runhai Stevia High Tech Limited ("Runhai"), a processing facility in the Anhui Province city of Mingguang. The agricultural region around Mingguang is also one of the largest and best stevia growing areas in China. The construction of Runhai is part of an agreement between GLG Life Tech Corporation and local governments to exclusively grow and manufacture stevia in this area. Phase one construction at Runhai was completed in December 2008.
