The rotary kiln used in the manufacturing process of cement is featured with very high temperature kilning, which can not only effectively minimize waste, but also converting it into alternative raw material and fuel to reduce the use of natural raw material and fuel during the cement production process, an important driver of circular economy. Through the recycle and reuse, waste is converted into resources, the sustainable benefits to the environment (E), society(S) and economy(G) can be obtained by reducing the consumption of natural resources and green house gas emission, and creating job opportunity.
 

A Model of Circular Economy

In compliance with UN’s goals of sustainable development SDGs12, Asia Cement strives to ensure sustainable consumption and production method. It focuses on implementing sustainable management and efficient use of natural resources, and largely reducing the generation of wastes by way of prevention, volume reduction, recycle and reuse.

Asia Cement has been striving for circular economy and reducing the consumption of resources and the emission of GHG to create new value for cement industry. It has been recognized domestically and internationally for many years. Asia Cement is very much willing to share the experiences of resources reuse and to work with the companies in the cement industry to enhance the capacity of processing wastes, furthermore, to aggressively drive for the transformation of energy and resources, hence, to push Taiwan moving towards a sustainable and renewable green homeland.

Investment of crtitical resources for circular economy

Asia Cement generated critical resources relating to alternative raw material and fuel, and focused on product quality and emission monitoring. Hence, it was able to completely reuse wastes and resource-recoverable products. Asia Cement Hualien Plant continuously invests into circular economy, the total fixed cost of the critical resources in 2022 was NT$0.14 billion.

Sustainable cycling and co-processing of resources in cement production process

Co-processing waste

Asia Cement applies for reuse and operates according to the laws and regulations of our country and further complies with the Global Cement and Concrete Association (GCCA) Guidelines. Since some waste possesses chemicals, material characteristics, or potential hazards that might jeopardize the safety or operation of cement plants or is likely to cause collateral material environmental impact when used in a cement plant, Asia Cement pledges not to co-process the following waste in cement kilns

Alternative raw material and fuel
