Enhancing sustainability across the entire life cycle of concrete—spanning raw material sourcing, manufacturing, construction, use, and end-of-life—is essential to reducing resource consumption and greenhouse gas (GHG) emissions.
Sustainably Circular
At Sika, we are sustainably committed, innovative, impactful, and growing.
Circularity has become essential throughout the entire lifecycle of concrete to meet sustainability goals. That’s why we’ve developed SikaCircle — a holistic approach offering solutions that are circular, durable, low in greenhouse gas emissions, resource- and energy-efficient, and smart, tailored specifically for our concrete producer customers.
SikaCircle unites all our circularity-focused initiatives, encompassing not only cutting-edge admixture technologies but also services, tools and equipment, digital apps, and more—supporting our shared sustainability objectives.
We are sustainably circular.
Cut Carbon, Not Performance
The Future of Low-CO₂ Concrete with Sika
Concrete is the second most consumed material on the planet after water, but traditional cement production contributes to around 7% of global CO₂ emissions. At Sika, we’re driving change with innovative solutions that lower the carbon footprint of concrete—without compromising performance.
CARBON FOOTPRINT FOR TYPICAL CONCRETE VS SUSTAINABILITY POTENTIAL WITH SIKA ADMIXTURES
How We Reduce CO₂ in Concrete and Maintain Performance
The key to sustainable concrete is reducing the use of CEM I, the primary source of emissions in conventional mixes. By leveraging advanced low-carbon admixtures, you can replace CEM I with high levels of Supplementary Cementitious Materials (SCMs) such as GGBS or PFA—while maintaining strength, durability, and workability.
Sika’s cutting-edge technology makes this transition seamless, enabling the construction industry to build smarter and greener.
