Metakaolin: Green Cement

The Future of Construction: Reducing CO₂, Strengthening Performance, Scaling for Impact

The Challenge: Cement’s Carbon Problem

Cement is the backbone of modern infrastructure, but it comes at a high environmental cost. For every ton of cement produced, up to 1 ton of CO₂ is released making cement production one of the largest
industrial sources of greenhouse gas emissions.

The culprit: Clinker.
A critical cement component, clinker is produced through the high temperature calcination of limestone, requiring immense energy and releasing carbon trapped within the raw materials. Reducing clinker is the key to truly green cement.

This is a powerful Green Story: Metakaolin enhances durability, minimizes efflorescence, and
aligns perfectly with sustainable concrete goals.

The Artemyn Vision: A Low-Carbon Future Starts Now

At Artemyn, we are committed to transforming the cement industry by replacing clinker with metakaolin, a widely available and highly efficient alternative. Our People, Nature & Innovation pillars drive us to
develop sustainable solutions without compromising performance or scalability.

Why Metakaolin is the Future of Green Cement

✔ Clinker Replacement = Lower CO₂ Significantly reduces cement’s carbon footprint while
maintaining strength and durability.
✔ Universally Scalable Unlike some green cement solutions that depend on rare materials, kaolin and metakaolin are abundant and globally accessible.
✔ Hard Kaolin Offers Superior Performance High pozzolanic activity enhances cement strength and workability, making it the best candidate for large-scale clinker replacement.
✔ Scale Our two mines at Capim form the world’s largest kaolin production hub, with a combined capacity to produce over 2 million tons of hard kaolin per year, ensuring a consistent, high-quality supply for cement manufacturers worldwide..

A Future-Proof Solution in a Fragmented Market and Facilitating the decline in Fly Ash

Supply Chain: Not all green cement technologies are viable everywhere—many depend on local material availability and emerging regulations. But metakaolin offers a reliable, globally deployable solution that helps cement producers meet current and future environmental targets.

Fly Ash Decline: With coal plants shutting down, fly ash availability is dropping (projected to fall below
15 million tons by 2030), pushing the industry toward alternatives.

Our Strategic Advantage: Sustainability at Scale

Industrial Readiness Unlike niche alternatives, metakaolin is proven, scalable, and available now.
Aligning with Carbon Legislation As carbon pricing and sustainability mandates tighten, metakaolin positions cement producers to stay ahead of regulatory shifts.
