As the construction industry faces growing pressure to reduce its environmental impact, the focus is rapidly shifting from operational efficiency to the carbon footprint of the materials used to build our cities. From embodied carbon and circular construction to carbon-negative innovations, sustainable building materials are redefining the future of infrastructure. In this exclusive interaction, Tarun Jami, Founder & CEO of GreenJams, shares his insights on why the construction sector must embrace climate-positive materials, how Agrocrete® is transforming agricultural waste into high-performance building products, and his vision for making every building a part of the climate solution rather than the problem
Q1. Construction contributes significantly to global emissions. Where do you think the industry has gone wrong?
Construction has traditionally optimized for cost, speed, and structural performance while overlooking one of its biggest hidden impacts, embodied carbon. Materials like cement and fired clay bricks have remained largely unchanged for decades despite their enormous environmental footprint. As the world urbanizes rapidly, continuing to build with high-carbon materials is no longer sustainable. We believe the next era of construction must move beyond simply reducing emissions to actively removing carbon from the built environment. If buildings can become carbon sinks instead of carbon sources, construction can shift from being part of the climate problem to becoming one of its most effective solutions.
Q2. What makes Agrocrete different from conventional building materials?
Agrocrete is fundamentally different because it transforms agricultural residues and industrial by-products into high-performance construction materials. Crop residues that are often burnt in fields become valuable raw materials, while industrial waste is given a second life instead of ending up in landfills. Through our proprietary technology, we create products that offer excellent structural strength, durability and improved thermal insulation, all while significantly lowering embodied carbon. The idea was never to develop a “green alternative” that compromises on quality. Our objective has always been to deliver a material that performs as well as—or even better than—traditional construction products while creating measurable environmental benefits.
Q3. Is affordability still a challenge for sustainable construction?
That’s one of the biggest misconceptions surrounding sustainable construction. For years, environmentally friendly materials have been perceived as premium products that increase project costs. Our experience has shown the opposite can be true when sustainability is integrated intelligently into material design. Agrocrete can help reduce construction costs through faster installation, lower material wastage and better thermal efficiency, which translates into lower energy consumption over the building’s lifecycle. Sustainability should create long-term economic value, not an additional financial burden. Once developers realise that climate-positive materials also improve business outcomes, adoption becomes much faster and more widespread.
Q4. How important is circular economy thinking in construction?
It is essential because construction has historically operated on a linear model: extract, manufacture, use and discard. That approach is no longer viable in a resource-constrained world. Agriculture generates enormous quantities of biomass waste, while industries produce mineral by-products that often become environmental liabilities. Circular construction transforms these waste streams into valuable resources, creating benefits across the entire ecosystem. Farmers gain additional income, industries reduce waste disposal challenges, and developers gain access to more sustainable materials. When multiple sectors benefit simultaneously, sustainability becomes commercially viable rather than dependent solely on regulation.
Q5. What is your long-term vision?
Our ambition extends far beyond creating better building materials. We want to redefine construction itself as a climate solution. Every building should contribute positively to the environment while delivering superior performance, affordability, and durability. We envision a future where carbon-negative materials become the industry standard rather than a niche innovation. If every infrastructure project actively removes carbon while meeting the demands of modern development, we can fundamentally reshape how cities grow. That is the future GreenJams is working towards every single day.
