Episode 5: Rhea Dabriwala and Naveen Shivalingam (Ground Up) - Turning Agricultural Residue into Climate Solutions

Episode summary

Rhea Dabriwala and Naveen Shivalingam, Co-Founders of Ground Up, discuss biochar, high-integrity carbon removal, and the transformation of Indian agriculture on Episode 5 of Scaling Green Tech, a podcast by Adopter.Dabriwala and Shivalingam argue that carbon markets are in transition from version 1.0 - renewable energy credits that financed solar deployment across the Global South - into a second generation focused on physically removing CO2 from the atmosphere. Ground Up converts agricultural waste that Indian farmers would otherwise burn into biochar, a stable carbon-rich material that locks carbon into soil for 200 to 1,000 years. According to a Carbon Removal India Alliance white paper, India's biochar potential is approximately 0.9 gigatons of CO2 per year - one sixth of the IPCC's estimated global removal requirement. Ground Up is building the industrial hub infrastructure to capture that potential, starting with a 44-ton-per-day facility due to commission in December.This episode is relevant for carbon market investors, corporate sustainability buyers, agricultural technology founders, and policymakers working on durable carbon removal, voluntary carbon market integrity, and agricultural resilience in high-biomass emerging economies.

Guest profileS

Rhea Dabriwala and Naveen Shivalingam are Co-Founders of Ground Up, alongside a third co-founder with a background in green mobility and electric vehicles in India. Before founding Ground Up, Dabriwala and Shivalingam built Peak 365, a carbon markets brokerage and consulting firm focused on the Global South. That work gave them close working knowledge of carbon project development, credit quality, and market dynamics. Dabriwala identified the pivot to biochar, recognising that voluntary carbon markets were shifting toward measurable, permanent, land-based removal. Both founders relocated to India in late 2023 following an initial scoping trip, and have since closed a $5 million seed round to scale their hub model nationally. They were formed as founders through Durham Venture School, a six-month programme run by the careers and enterprises team at Durham University.Ground Up builds industrial-scale biochar production hubs in agricultural communities across India. The company converts crop residues that would otherwise be burned into biochar - a high-carbon soil amendment that improves crop yields, reduces fertilizer use, restores degraded soils, and generates verified carbon removal certificates.

Key takeaways

  • India produces 500 to 600 million tons of agricultural residues per year, most of which are burned at harvest time. Ground Up converts this waste stream into biochar at industrial scale.
  • According to a Carbon Removal India Alliance white paper, biochar has the potential to remove approximately 0.9 gigatons of CO2 per year in India - one sixth of the IPCC's estimated annual global removal requirement of six gigatons.
  • Biochar locks carbon stably into soil for 200 to 1,000 years, supported by the hydrogen-carbon molecular structure of individual biochar particles. Registries including Isometric and puro.earth have developed detailed independent methodologies to verify this.
  • Ground Up's full-scale industrial facility, due to commission in December, has a capacity of 44 tons of biochar per day, using sugarcane leaves and tops that would otherwise be burned.
  • India's average smallholder farm is 0.74 hectares. Ground Up scales by working through food processing mills and agricultural companies rather than individual farmers, allowing a single commercial relationship to reach millions of growers.
  • Ground Up's eight-month biochar trial programme in Maharashtra showed improved water retention, reduced fertilizer requirements, and higher crop yields across multiple crop types.
  • Climate change is already reducing crop productivity in India's northern states by up to 18% across key crops including sugarcane, rice, and wheat. Biochar application can restore organic carbon levels and partially reverse this degradation.
  • Each Ground Up biochar hub employs between 20 and 100 people within the local agricultural community, creating formal employment in the emerging global carbon removal economy.
