XeroCarbon Cement is a Bangalore-based venture at the forefront of sustainable cement production. Our mission is to transform the traditionally carbon-intensive cement industry into a beacon of sustainability by producing net-zero carbon clinker through innovative renewable energy and carbon capture technologies.
Our Innovation
At XeroCarbon, we’ve pioneered the integration of two key technologies:
1.Solar Kiln Technology: Using concentrated solar energy, our kilns achieve the high temperatures required for calcination without the use of fossil fuels, eliminating significant CO₂ emissions.
2.Algae CO₂ Scrubbing: Our advanced algae photo-bioreactor captures CO₂ released during the calcination process and converts it into valuable by-products like biomass, contributing to a circular economy.
These innovations allow us to reduce CO₂ emissions by up to 798 kg per ton of clinker, setting a new standard in sustainable production.

XeroCarbon Cement is an innovative venture dedicated to revolutionizing the cement industry by creating net-zero carbon clinker through groundbreaking technologies. Based in Bangalore, India, XeroCarbon aims to address one of the largest contributors to global CO₂ emissions—cement production—by leveraging renewable energy and carbon capture techniques.
At the heart of our innovation is the Solar Kiln, powered by concentrated solar energy, achieving the high temperatures needed for calcination without reliance on fossil fuels. Complementing this is our Algae Photo-Bioreactor, a cutting-edge carbon scrubbing system that captures CO₂ emitted during production, converting it into valuable by-products. Together, these technologies make our process environmentally sustainable and commercially viable.
Our solution targets both integrated cement manufacturers and grinding units, offering a local, sustainable alternative to imported clinker. In addition to reducing carbon emissions by up to 798 kg per ton of clinker, we pledge 10% of our production to NGOs supporting disaster relief and rebuilding efforts, ensuring the poorest and most vulnerable communities benefit from net-zero cement.
XeroCarbon Cement is more than a business—it's a movement to lead the cement industry into a greener, sustainable future, driving impact on both environmental and social fronts.

At the heart of our innovation is the Solar Kiln, which replaces traditional fossil fuel-based energy with concentrated solar power. Using a system of high-precision linear reflectors and advanced solar concentration receivers, we achieve the extreme temperatures (1400°C–1500°C) required for calcination. This process significantly reduces CO₂ emissions while maintaining energy efficiency.

To tackle unavoidable CO₂ emissions from the calcination process, we’ve developed an algae photo-bioreactor that captures and sequesters carbon dioxide. The algae convert CO₂ into valuable biomass by-products, which can be used in industries such as agriculture, bioenergy, and cosmetics. This innovative solution not only reduces emissions but also adds value to the carbon capture process.
