Through localized calcined clay (deOHclay) technology, Taiwan Cement Group has reduced the proportion of clinker to 50%, reduced carbon by 40%, and achieved an annual production capacity of 1.5 million tons, thus promoting the large-scale implementation of low-carbon cement.

According to the 2025 Sustainable Development Report released recently by CIMPOR, the European cement business of

Taiwan Cement Group, the total annual production capacity of calcined clay in Portugal and Africa has reached 1.5 million tons . Low clinker is the main source of cement strength, It needs to be fired at a high temperature of about 1450 C . Reducing the proportion of clinker in cement is an important technical direction of the global cement industry and a key link to reduce the carbon footprint of products. The burning temperature

clinker is about 1450 ℃, and

reducing the proportion of clinker is the key to reduce the carbon footprint of products.

these materials are collectively referred to as supplementary cementitious materials (SCM).". In the past, slag and fly ash were commonly used, but they were by-products of iron and steel and thermal power generation respectively, and the supply was affected by upstream industries. Calcined clay is one of the important low-carbon materials continuously invested by the international cement industry in recent years.

The natural clay has no cementitious activity, can participate in the cement reaction after being calcined and activated, and can replace part of high-carbon clinker in the cement formula. Clay is abundant and widely distributed, and its calcination temperature is much lower than that of clinker . The strength, durability and workability of the cement can be maintained under the

reasonable formula, and the carbon footprint of the product is reduced accordingly.

The KRIBI plant in Cameroon uses local clay to make calcined clay by flash calcination and produce low-carbon cement without traditional clinker kilns.

This layout also reflects the core idea of Taiwan Cement Group to develop global low-carbon building materials.

Cement is a highly localized industry, with different markets having different conditions for limestone, clay, energy and alternative raw materials.

Low-carbon transformation is not to copy the same cement formula to the world, but to find the lowest carbon production mode that can be achieved locally according to local resource conditions. The calcined clay deOHclay developed

by CIMPOR is a concrete practice of converting local clay resources into low-carbon cement raw materials.

Taiwan Cement Corporation has incorporated deOHclay into the "Total Climate Portfolio Climate Resilient Products" layout.

From the laboratory to the factory

, from the research and development of deOHclay technology, to the landing in Africa, the expansion in Europe, and then to the production capacity of 1.5 million tons, CIMPOR is gradually becoming an important part of the global low-carbon cement layout of Taiwan Cement Group from a material innovation.

For the cement industry, carbon reduction technology should not only be proved to be "done" in the laboratory, but also be able to enter the factory, stabilize production and enter the market.
