The New Mix: Bio-Based Concrete with GreenJams | Spill the C #13

Welcome to another episode of Spill the C!This time, we’re talking buildings buildings — but from the ground up. Cement and concrete are responsible for 8% of global emissions, and still don’t get enough attention in climate discourse.I sat down with Tarun, Founder and CEO of GreenJams, to explore how their carbon-negative building material, Agrocrete®, is turning agri-waste into high-performance, cost-efficient bricks and blocks. We unpack the science behind carbon sequestration in construction, the trust gap in India’s built environment sector, and what it takes to mainstream material innovation in such a legacy-driven space.00:00 – Introduction02:10 – Tarun’s Journey into Green Building Innovation14:55 – The State of the Construction Industry 16:15 – Embodied Carbon and Cement’s Climate Footprint18:30 – Why It’s a Value-Driven Market, Not Just Price Sensitive26:20 – How Agrocrete® Is Made (and What It’s Replacing)30:05 – Working with Agri-Waste & Farmer Incentives32:05 – What It Means to Be Carbon-Negative35:05 – Functionality & Performance of Agrocrete®39:02 – Who’s Buying It: Early Adopters46:10 – The Regulation Problem: Why New Materials Can’t Get Certified51:30 – What’s Next for GreenJams53:00 – Closing ReflectionsTarun Jami, Founder at GreenJamsLinkedIn: https://in.linkedin.com/in/tarunjami Website: https://greenjams.org/ LinkedIn: https://in.linkedin.com/company/thegreenjams 🎬Edited by: Purajit Sonowal🌿Studio Host: The Studio by Copper+ClovesThe Studio offers a vibrant, multi-use space designed to promote wellness and community engagement — offering Yoga/Pilates and Muay Thai classes, a plant-based café, co-working space, and rental opportunities for anyone looking to host private events or simply wondering where to schedule their next client photoshoot.Website: https://copperandcloves.com/Instagram: https://www.instagram.com/thestudiobycopperandcloves/?hl=en📌Relevant Links & Resources:GreenJams’ product technical comparison sheet >> https://docs.google.com/spreadsheets/d/1O_UE1yv5ntFoNxi8CHVLjokUv3mauryt/edit?gid=367233856#gid=367233856A summary of India's major green building certificationsystems>> https://www.commercialdesignindia.com/insights/9050-a-summary-of-all-the-indian-rating-systems-for-green-buildingsA paper on Science Direct which provides a comprehensive analysis of decarbonising cement andconcrete production >> https://www.sciencedirect.com/science/article/pii/S2352710224004297Shakti Foundation’s snapshoton the current state of the brick industry + environmental impacts>>  https://shaktifoundation.in/wp-content/uploads/2018/04/Roadmap-for-promoting-Resource-Efficient-Bricks-in-India-Summary-report.pdfUN GlobalABC’s insights into India’s building sector, fromhousing gaps to environmental impacts >> https://globalabc.org/resources/publications/building-market-brief-india
