Second, sustainable mines

Asia Cement sets the mine's sustainable vision to balance economic, social and environmental aspects, conducts an assessment of the complete life cycle mine, and begins planning the mine closure plan after the end of the mine operation. Mining is a temporary land use. After mining, the mine can be revitalized to revitalize the land, achieve sustainable use of the environment, and form new economic activities. In 2017, Asia Cement's implementation in sustainable mines includes: complete mining and ecological greening afforestation process, imitation natural ecological green chemical method, innovative phytosanitary rapid green chemical method, mining area phytoremediation normalization difference phytoheological index NDVI analysis, villagers participating in mine safety And the information is open to the public and continually practice such as blasting vibration control, and the self-determined perpetual mine indicators total four projects to disclose eight sustainable indicators for strict self-management supervision.

Third, low carbon green process

Asia Cement's efforts in low-carbon green processes include demonstration projects to promote voluntary greenhouse gas reduction, cement mill low-carbon improvement, and research and development of concrete. The execution details are as follows:

Promote voluntary reduction of greenhouse gases: Cement manufacturing is a high-energy-consuming industry. The production process consumes a large amount of fuel and electricity and emits considerable greenhouse gases. In order to effectively save energy and reduce emissions, the Asian Cement Hualien Plant has attached great importance since its establishment. Energy resources consumption, actively adopting the latest energy-saving equipment and technology, Asia Cement Hualien Factory was awarded the “Industrial Greenhouse Gas Voluntary Reduction and Excellent Manufacturer Award” by the Ministry of Economic Affairs for the first time in 2009, followed by 2012, 2013 and 2015. In 2016 and 2017, the awards were successively awarded. From 2009 to 2017, the Yali Hualien Factory has included six of the eight outstanding manufacturers awards from the Industrial Bureau, which can be regarded as the best example of the friendly cement industry in the domestic cement industry. The specific energy-saving and carbon-reduction measures that have been confirmed and awarded by the Industrial Bureau have mainly included waste heat recovery power generation, powder separator efficiency improvement projects, cement grinding addition materials, cooling machine heat recovery efficiency improvement projects, and preheater heat energy efficiency improvement projects. Rotary kiln main motor speed increase project and preheating machine upwind air duct extension...etc.

Cement mill low carbon improvement demonstration plan: In 2017, Asia Cement Hualien Plant planned to invest 70 million yuan to implement the cement mill low carbon improvement plan. This project utilizes a new combined dynamic static separator system, which can After the vertical mill exit, the material is divided into three parts: coarse and medium. The coarse material is returned to the CKP vertical mill to continue grinding. The medium is sent to the ball mill to continue grinding. The finest material is collected by the cyclone as a finished product and directly enters the cement storage. . After this process is improved, the particle size of the ball mill is controlled by the classifier, which prevents the large particles from entering the ball mill and affects the grinding efficiency of the ball mill. It can also avoid excessive fine powder returning to the CKP vertical mill, affecting the CKP. The work of the vertical mill. In this way, the quality of the finished product is improved and the unit production capacity is increased, and the energy consumption per unit of the system is also reduced. Asia Cement also conducted demonstrations to provide cement peers to the factory for on-the-spot observation, and shared the experience of energy saving and carbon reduction to the cement industry. The trend of the cement industry to follow the example.

R&D 墁laying cement: In 2017, the cement-based cement solution for Asian Cement R&D was awarded to the Excellent Qualified Voluntary Reduction Program of the Ministry of Economic Affairs. Asia Cement Hualien Factory adheres to the spirit of corporate responsibility for society and customers, and provides a more convenient construction environment and quality for local clay masters through R&D and production of special concrete for cement, and at the same time, for the environmentally conscious Taiwan society. Environmental protection. Therefore, research and development can allow the mud master to simply use cement, without adding chemicals, it can save labor, strengthen the bonding force, greatly reduce cracks and reduce greenhouse gas emissions, and achieve comprehensive results.

Fourth, the specific results

Sustainable mine specific results:

According to the mining and ecological afforestation process, a total of 4,337 trees were planted in 2017, and the area of ​​greening and rebuilding was 2.8 hectares.

In 2017, the mine has been greened and rehabilitated with an area of ​​61.3 hectares and a mining operation area of ​​22.0 hectares. The greening area accounts for about 73.59% of the mine area.

Innovative vegetative package rapid green chemical method can shorten the coverage rate of 5 meters above the tree height of 3 years or more to 4 months.

The normalized Difference Vegetation Index is performed on the normalized Difference Vegetation Index of the vegetative re-cultivation in the mining area. After 18 years of re-cultivation, a 100% recovery ratio can be achieved.

In 2017, the self-sustained mines totaled eight sustainability indicators for four projects. In the three-law (law, other law and self-discipline) self-evaluation method, the indicators are in line with the situation. In addition to the soil and water conservation in the mining area is legally mandated, most of the remaining mine sustainability indicators are above the legal requirements, and strict self-requirements to achieve sustainable goals.

In 2017, the National Cheng Kung University was commissioned to conduct monitoring and evaluation of blasting vibration in mining areas. After monitoring and analysis, more than 96% of the blasting vibrations were less than 1mm/sec, which was far better than one tenth of the US blasting vibration standard (19mm/sec).

A total of 989 factory and mining operators and third-party workers, including 427 aborigines, accounted for 43%.

In 2017, the mines were strengthened to communicate with each other. A total of 1024 visitors participated in a total of 30 echelons.

In 2017, the cost of mine planting and greening, blasting monitoring equipment and vibration monitoring and evaluation was 13.23 million yuan, and the related taxation fee of the mine mud Hualien plant was 1.28 billion yuan, and the local feedback was about 9.54 million yuan.

Green process specific results:

In the past years, we have promoted voluntary reductions, which can save up to 138 million kWh of electricity, 43,000 metric tons of coal and 300 metric tons of fuel oil per year, equivalent to reducing greenhouse gas emissions by 267,000 metric tons per year.

The investment of 70 million yuan will promote the cement mill low carbon improvement plan and increase the cement grinding efficiency by 10%. The cement mill consumption was reduced from 46.7 to 42.0 (kWh/ton cement) by 10%. Greenhouse gas reduction of 2,792 tons of CO2e / year.

Open the cement mill site for demonstration exchanges and promote the cement industry low-carbon process in the cement industry.

Developed special cement for concrete construction and obtained the voluntary reduction of excellent manufacturers and programs from the Industrial Bureau of the Ministry of Economic Affairs. In 2016, 2,597 metric tons of concrete was produced, equivalent to 51,940 bags of cement, which reduced greenhouse gas emissions by 366.2 tons of CO2e.
