Eco Path Innovations has completed two landmark infrastructure projects in Bengaluru, including India's first cement-free concrete road and a carbon-negative bituminous road. These projects utilize proprietary binder technologies and fiberglass composite rebars to reduce embodied carbon and eliminate the need for curing water. The company reports a saving of 34 tonnes of CO2 on the cement-free project and a net carbon-negative footprint of 3 tonnes of CO2 for the bituminous road. These developments aim to prove that sustainable, low-carbon construction is scalable for urban infrastructure in India.

Cement-free is a big claim. I want to see the maintenance data after three or four years of heavy monsoon cycles in Bengaluru. If these roads crack faster than standard concrete, the carbon savings are wiped out by the need for frequent repairs.

The real question is procurement. Most government contracts in India are based on the lowest bid for standard materials. Until there is a policy shift or a carbon credit incentive for the contractor, these projects will stay as niche pilots.

The carbon-negative claim on the bituminous road is only 3 tonnes of CO2. That is a tiny amount for an infrastructure project. Is this a meaningful sequestration method or just a rounding error in the lifecycle analysis?

Interesting use of fiberglass rebars to replace steel. That removes a huge chunk of the embodied carbon. It would be useful to know if the proprietary binder is based on fly ash or slag, as that affects the supply chain scalability.
