The idea
Across India, invasive plants and crop waste are often burned in the open. We think that waste can do more good. Turned into biochar, a stable charcoal that locks carbon away for a long time, it can earn carbon credits, which companies buy to offset their emissions.
The same biochar can go into building blocks made by women from local self-help groups, who earn wages for the work. Value from both streams flows towards one purpose: a home where children without parents grow up with a house mother, good food and good schooling.

The question we're exploring
Can waste that would otherwise be burned become climate value and useful building material, and can that work help pay for a children's home?
Two connected parts
Indo Karbon
Making biochar from invasive plants such as prosopis juliflora and lantana, and from crop residue such as wheat straw, at low cost and to a high, verifiable standard. That means understanding machines, feedstock (the plant waste fed in), capacity, and what carbon-credit registries require.
Indo Kids
Using biochar in concrete blocks, pavers and precast parts for village councils, rural housing and the open market. The purpose behind it is a home for 10 to 15 children, supported by company social-responsibility giving (CSR), environmental and social funding (ESG) and the UN Sustainable Development Goals.
What we work on
- Cost and capacity modelling for turning different plant wastes into biochar
- How biochar behaves in concrete and building blocks
- Carbon-credit integrity, including "additionality": showing the climate benefit would not happen without carbon-credit money
- Community work with farmers and women's self-help groups
- Short explainer films for parents, youth, farmers, donors and nature lovers
Methods
- Pyrolysis
- Heating plant material with little oxygen so it becomes biochar instead of burning away.
- Carbon-credit methods
- The rules registries use to check and count the carbon stored.
- Modelling and materials research
- Financial models, data analysis and tests of biochar in concrete.
- Film and AI-assisted research
- Explainer films for outreach, and AI as a research and modelling partner.
