What GreenJams does
GreenJams BuildTech Pvt Ltd is an India-based climate-tech company that develops and sells carbon-negative construction materials as alternatives to conventional cement and clay bricks. Founded in 2017 by Tarun Jami (CEO) and Er. JLN Murty (Managing Director), GreenJams is headquartered in Visakhapatnam with additional presence in Bengaluru, Mysore, and a manufacturing base in Roorkee. The company primarily serves real estate developers, builders, contractors, architects, industrial customers, and individual homeowners across India, with a customer base exceeding 200 entities spread across eight states.
The company's core technology centers on two patented product lines: Agrocrete®, a carbon-negative bio-concrete building block (available in hollow and solid variants) made from upcycled crop residues — paddy, sugarcane, wheat, and soybean stalks — combined with industrial byproducts such as steel slags and ashes; and BINDR™, an ultra-low-carbon alkali-activated binder offered in three formulations (BINDR-GP for general purpose, BINDR-RS for rapid set, and BINDR-FN for finishing). Manufacturing uses low-energy mixing without kilns or high-temperature processing, with Agrocrete® achieving a verified embodied carbon of -0.14 kg CO2e/kg under EN 15804+A2, and BINDR™ operating at approximately 0.1–0.23 kg CO2/kg versus roughly 0.9 kg CO2/kg for ordinary Portland cement. Documented performance claims include 3.5x higher thermal insulation, 2.5x faster masonry, and 50% lower construction costs versus conventional bricks, all of which contribute to LEED, GRIHA, and IGBC certification pathways.
GreenJams monetizes through three revenue streams: project-area-based unit pricing of Agrocrete® blocks, sales of BINDR™ binder in powder form, and verified carbon removal credits tied to permanent CO2 sequestration in Agrocrete® walls. Distribution is direct via the company website (sample ordering through Razorpay, quotation requests) supplemented by enterprise field sales targeting developers, architects, and industrial accounts, with case studies documenting fulfilled deliveries including a 2,400 km cross-country shipment from Roorkee to Chennai for a CBRE services building. The company is privately held with disclosed cumulative funding of approximately $443,000 across grants and accelerators (IKEA Foundation, Villgro, MassChallenge, Agence Française de Développement, Habitat for Humanity, Third Derivative), 141 direct employees plus 195 in its supply chain, and recognition including the Solar Impulse Efficient Solution Label awarded in October 2025.

GreenJams product offering
Product offeringCore offering
GreenJams manufactures and sells Agrocrete®, a patented carbon-negative bio-concrete made from upcycled agricultural crop residues (paddy, sugarcane, wheat, soybean stalks) and industrial by-products (steel slags, ashes), combined with BINDR™, its proprietary alkali-activated binder. The company sells hollow and solid construction blocks and binder variants for mortars, plasters, repairs and finishing as a drop-in replacement for conventional clay bricks, cement and concrete in the construction industry.
Product overview
GreenJams offers a portfolio of carbon-negative construction materials centered on two core products: Agrocrete® and BINDR™. Agrocrete® is a patented carbon-negative bio-concrete made from agricultural residues and industrial by-products, available as hollow blocks and solid blocks for various construction applications. BINDR™ is an ultra-low-carbon cement alternative binder derived from metallurgical slags, offered in three formulations (General Purpose, Rapid Set, and Finishing) for different construction needs. These products work together as a complete walling and binding system, replacing conventional cement, bricks, and concrete while achieving carbon-negative performance and superior thermal insulation.

GreenJams competitors and assessment
Company assessmentDirect peers
- CarbonCure Technologies: Canadian climate-tech company that injects captured CO₂ into concrete mixes to reduce embodied carbon and enable carbon credit generation. Closely comparable to GreenJams as both sell verified carbon-reduction/-removal attributes alongside a physical concrete/block product to construction customers.
- Biomason: US-based producer of bio-based masonry units grown from bacteria and aggregate inputs without kiln firing. Directly comparable to GreenJams' Agrocrete® in positioning bio-based, low-energy, kiln-free alternatives to fired clay bricks.
- Brimstone: California-based startup making carbon-negative Portland cement from calcium silicate produced using silicate rocks instead of limestone. Adjacent competitor addressing the same carbon-negative construction materials thesis, and a potential acquirer or partner for BINDR™-style applications.
- Solidia Technologies: US developer of CO₂-cured concrete products using a non-hydraulic binder, reducing carbon footprint in precast concrete. Comparable in targeting low-emission cementitious binders and precast masonry for sustainable construction.
Emerging players
- Hoffmann Green Cement Technologies: French-listed company producing low-carbon clinker-free cements (H-UKR, H-IA, H-PUR) using blast-furnace slag and alkali activation. Direct technology analog to BINDR™ via its alkali-activated geopolymer chemistry in the cement-alternative category.
- Ecocem: Ireland/France-based producer of low-clinker, high-slag cements (ECOPlanet) and supplementary cementitious materials for ready-mix and precast concrete. Comparable as a binder-focused low-carbon cement alternative sold to concrete producers.
- LC3 Project: International R&D consortium promoting Limestone Calcined Clay Cement as a clinker-reduced alternative, with Indian partners including IIT Delhi. Comparable in promoting an alternative cementitious binder that reduces CO₂ in concrete and is broadly available to the Indian construction ecosystem.
Others
- CarbonCure (India operations): CEMEX, Holcim, and Saint-Gobain — alongside GreenJams in the Solar Impulse comparison — all operate global low-carbon concrete product lines (Vertua, ECOPlanet, ECOPact) with R&D into carbon-negative or carbon-sequestering solutions. Comparable as broad incumbents expanding into the category GreenJams was first to commercialize in India.
Regional players
- ACC Limited (Adani Group): India's second-largest cement company, part of Adani Group, with growing ACC Ecoplus and blended-cement lines targeting lower embodied carbon. Regional incumbent competing in the same Indian B2B infrastructure/real-estate customer base that GreenJams targets.
- Ultratech Cement (Aditya Birla Group): India's largest cement manufacturer and the dominant Indian supplier to developers, builders, and infrastructure projects. Comparable as the incumbent standard against which Agrocrete® competes in India, with growing green-product portfolio that could be augmented to mirror GreenJams' positioning.
