we provide hari mati (a proprietary combination of organic inputs and silicate-rich amendments) to our farm partners. when spread on farmlands, it releases essential nutrients, promoting healthy crop growth and stabilising soil ph. it also accelerates trapping co2 from rain water.

the technology

our technology is designed to measure the removal of CO2 across land, water and ultimately earn carbon credits. mapping vast tracts of land, collecting soil samples, pour water samples and geological data at scale is a technological challenge that’s a strong moat to earning carbon credits.

we’re also building Atlas, a proprietary data platform that creates a high-resolution, longitudinal record of critical environmental parameters like soil chemistry & mineralogy, groundwater dynamics, microclimatic conditions, and stream quality, across Eastern India. we are also building statistical and AI models (Feluda AI) on top of Atlas to scale ERW across different crop types in South Asia. 

research & development

enhanced rock weathering (erw) is a novel space. we want to be at the forefront of pioneering innovation in removing carbon at scale. we currently have two labs — in the prestigious indian institute of science (iisc) in bengaluru and the darjeeling climate action lab (d-cal) in darjeeling. 

we’re expanding our lab capacity and hiring scientists to expedite our research & development in carbon removal technologies. d-cal will overcome the constraints of sampling, testing and defining methodologies by processing up to 600,000 samples annually by 2025.
