At the end of 2019, Yunnan Yimen Dachunshu Cement Co., Ltd. eliminated the original two low-efficiency cement clinker production lines with a daily output of 2500 tons and 1500 tons, and built a new dry-process cement clinker production line with a daily output of 4000 tons through capacity replacement, which was formally put into operation in June 2021.

In the process of promoting the transformation and upgrading of the cement industry, Yunnan Yimen Dachunshu Cement Co., Ltd. focuses on improving the green low-carbon cycle development production system, constantly explores effective carbon reduction paths, and builds a green factory model in the cement industry through internal environmental supervision and governance.

In order to alleviate the shortage of electricity, the company uses roofs, parking spaces, belt transportation corridors and slope areas to build 8500 solar photovoltaic panels, covering an area of 178500 square meters, with an installed capacity of 4.7 MW, which solves part of the electricity demand of the company.

"The first phase of 4.7 MW has been successfully put into operation, with an annual power generation capacity of more than 7 million degrees, adopting the mode of" self-use, surplus electricity access to the grid ". As of April 30 this year, the cumulative power generation capacity is 8.164 million degrees, and the energy-saving effect is obvious," said Tian Xiaowen, manager of the comprehensive department of Yunnan Yimen Dachunshu Cement Co., Ltd. At the end of 2019,

Yunnan Yimen Dachunshu Cement Co., Ltd. eliminated two low-efficiency cement clinker production lines with a daily output of 2500 tons and 1500 tons, and built a new dry cement clinker production line with a daily output of 4000 tons through capacity replacement. It was officially put into operation in June 2021. The project supports the construction of 6 MW waste heat power generation project to realize low temperature waste heat recovery and utilization, which can replace 20% of the electricity required by the production line; By adopting the new generation of information and communication integration technology and advanced equipment, a new production mode with self-perception, self-adaptation, self-control, self-decision-making and self-execution has been constructed. Compared with before the transformation, the production efficiency has been increased by 24% and the operation cost has been reduced by 11.8%.

"The production line adopts the second generation of new dry cement technology, which is mainly embodied in the visualization of production management, intelligent equipment, fully automated laboratory and other technologies, and ultimately achieves the goal of first-level energy efficiency, environmental protection and ultra-low emission, increases the energy utilization rate by 12.6%, saves 1680 tons of standard coal and 240000 cubic meters of water annually." Sun Zhengfu, manager of safety and environmental protection department of Yunnan Yimen Dachunshu Cement Co., Ltd., said.

In 2023, Yunnan Yimen Dachunshu Cement Co., Ltd. was awarded the title of "National Green Factory" by the Ministry of Industry and Information Technology and the title of "Energy Efficiency Leader of Industrial Enterprises in Yunnan Province in 2023" by the Provincial Department of Industry and Information Technology, becoming a green development benchmark enterprise in Yimen Industrial Park. The relevant person in charge of

Yunnan Yimen Industrial Park Management Committee said, "The park will continue to promote low-carbon technological transformation of enterprises and recycling transformation of the park, realize cascade utilization of energy, recycling of water resources, waste exchange and utilization, land conservation and intensive use, and promote recycling production of enterprises, recycling combination of industries and recycling development of the park".
