Céline Klein, global head of low-carbon products at Holcim, notes that:“Calcined clay is a game-changer because we don’t need to build a new cement plant or change our production lines.” This means existing cement facilities can easily integrate calcined clay, accelerating adoption and reducing capital costs for decarbonization. • Industrial Take-up: • Holcim and Heidelberg Materials are actively investing in calcined clay production lines globally. • Several plants have already been retrofitted to produce calcined clay-based cement. • Global Relevance: • Particularly important in India, Brazil, Africa, and Europe, where supply constraints or emissions regulations are stronger. • Plays a vital role in helping producers meet EU Green Deal targets and carbon taxes. • Cost & Carbon Advantage: • Beyond environmental impact, calcined clay also lowers production costs due to reduced energy input. • As other SCMs decline in availability (e.g. fly ash from coal), calcined clay fills a critical gap.
