Bengaluru-based climate-tech startup Ecopath is transforming sustainable construction with EcoConcrete, a cement-free building material made using industrial by-products. Founded in 2024 by Sourabh Kumar and Abhishek Chhazed, the company aims to reduce the environmental impact of construction while making eco-friendly materials commercially accessible.
EcoConcrete uses ground granulated blast-furnace slag (GGBS), a by-product of steel manufacturing, along with proprietary binders to replicate the properties of conventional cement-based materials. According to the company, the material can be used to manufacture pavers, kerbstones, blocks and ready-mix concrete.
One of the key benefits of Ecopath’s technology is that it eliminates the need for water-based curing, helping conserve water and reduce construction-related emissions. The startup has also filed six patent applications, with five more in development.
Ecopath has progressed from product development to commercial operations, generating nearly ₹12 crore in cumulative revenue, according to co-founder Sourabh Kumar. The company expects revenue to exceed ₹50 crore by the end of the current financial year.
Currently operating in Bengaluru, Pune, Mumbai and Hyderabad, Ecopath plans to expand into at least 20 Indian cities. It is also exploring opportunities in international markets, particularly the Middle East and Africa.
Recognised as part of YourStory’s Tech30 cohort for 2026, Ecopath represents the growing focus on climate-friendly innovation in India’s construction sector. Its expansion highlights the potential of industrial waste to become a valuable resource for building more sustainable infrastructure.
