Summary: Huijia Biotech and Hirye Biotech are working on their stevia projects, with EI reports being publicised in late March and in early April, respectively.
On 27 March, the environmental impact (EI) report of Xinjiang Huijia Biotechnology Co., Ltd. (Huijia Biotech)'s stevia production and processing project (Phase I) was accepted and publicised.
Overview of Huijia Biotech's project:
Huijia Biotech has a 26.67 km2 planting base which functions on the "company + cooperative + farmer" model. Huijia Biotech's stevia production line was officially operational on 28 Nov., 2022, turning out 4 tonnes of stevia products on a daily basis by processing 30 tonnes of raw materials.
On 6 April, the EI report of Dongtai Hirye Biotechnology Co., Ltd. (Hirye Biotech)'s 10,000 t/a stevia deep processing technology upgrading project was publicised. This project is designed to change the production process of the 10,000 t/a stevia production project to further extract chlorogenic acid and stevia polysaccharide from Stevia rebaudiana by resin adsorption and reduce water usage.
Hirye Biotech's 10,000 t/a stevia production project is intended to be constructed over two phases. Phase I with a capacity of 3,000 t/a of stevia passed the environmental inspection and acceptance in 2018. But Hirye Biotech decided that it will not build Phase II with a capacity of 7,000 t/a of stevia. After years of research, Hirye Biotech finds that there are many healthy substances in Stevia rebaudiana besides stevia, especially chlorogenic acid and stevia polysaccharide. But since the 10,000 t/a stevia production project directly extracts stevia from the dried leaves of Stevia rebaudiana, a lot of healthy substances in Stevia rebaudiana were wasted. In addition, the original process adopts the water extraction method and uses a large number of flocculants such as lime to remove impurities, which consumes a large amount of water and further produces solid wastes.
Overview of Hirye Biotech's 10,000 t/a stevia deep processing technology upgrading project:
Besides the above-mentioned projects, Hirye Biotech also has a project called stevia production line upgrading project which plans to use the biogass generated in the production of stevia to produce steam. This project is constructed over two phases. Phase I producing 28,800 tonnes of steam per annum passed the environmental inspection and acceptance in March 2023. As for Phase II, Hirye Biotech originally planned to build a capacity of 79,200 t/a of steam, but as there is insufficient biogass, it will only build a 5 t/d biogas boiler, producing 36,000 tonnes of steam a year.
