In December 2012, the company undertook the "Inner Mongolia Yidong Group Dongxing Chemical Co., Ltd. 3x600 tons/day double chamber gas fired lime kiln project". The project broke ground on December 7, 2012, overcoming many unfavorable factors such as cross year, winter construction, and construction site limitations (requiring on-site pre assembly). After 100 days of construction, the three kilns achieved the lifting of the main steel structure of the kiln. The first kiln of this project was successfully put into operation on August 5, 2013.

After the kiln was put into operation, the company signed a production and operation contract with Party A. The new contract was successfully renewed in the third year.
