Bangalore, India — 23rd Oct 2025 — GreenJams, India’s pioneering bio-concrete innovator, has achieved a major global milestone with its flagship product Agrocrete® being awarded the Solar Impulse Efficient Solution Label — making it India’s only carbon-negative building material to receive this internationally recognised distinction for environmental and economic excellence.
Founded by explorer and clean-tech visionary Dr. Bertrand Piccard, the Solar Impulse Foundation grants the Label to solutions that successfully combine sustainability with profitability. Each selected technology undergoes a rigorous multi-expert assessment covering feasibility, environmental impact, and commercial viability, independently audited by EY.
Agrocrete® — a patented carbon-negative bio-concrete made from agricultural residues, industrial by-products, and GreenJams’ proprietary alkali-activated binder — replaces conventional concrete and brickwork while offering up to 90% lower embodied carbon, 3.5× higher thermal insulation, and superior durability. Every ton of Agrocrete® locks away approximately 140 kg of CO₂, effectively reversing emissions from the construction process.
“From day one, we’ve been deeply conscious about the kind of products we wanted to put out into the world,” said Tarun Jami, Founder & CEO of GreenJams. “We knew we had the capability to create world-class, category-defining materials that outperform conventional ones on both sustainability and performance. Agrocrete® earning the Solar Impulse Label validates that vision — it proves that what we’ve built is not just greener, but commercially viable and impactful at scale. I’m beyond thrilled and immensely grateful to the Foundation for this recognition."
With this achievement, GreenJams joins a select group of global building-material leaders — including Holcim, Saint-Gobain, CEMEX, and Gresmalt — who have also been recognised by the Foundation for their pioneering climate-positive innovations.
To date, GreenJams has deployed Agrocrete® across 16 commercial projects in India, capturing over 300 tonnes of CO₂, avoiding 900 tonnes of emissions, and delivering nearly 2,000 m³ of structural bio-concrete.
This recognition reinforces GreenJams’ mission to make buildings agents of climate-change reversal, combining material science, circular design, and industrial scalability to redefine how the world builds.
