Project description
KisanKrete is developing carbon-negative cement using rice husk ash, calcined clay, and CO₂-absorbing minerals, aiming to replace half the clinker while drawing on India's agro-waste research and creating rural income from waste collection.
The beVisioneers journey
Developed zero-cement tiles from rice husk, converting agricultural waste into a functional construction material. Processed ~750 kg of rice husk, reaching meaningful pilot-scale usage beyond small lab samples. Validated thermal insulation performance and completed lab testing confirming material properties.
Key Highlights
- 750 kg of rice husk processed into zero-cement tiles and construction material
- 4 customers / beneficiaries
- 3 team members
- €18,000 secured (Emergent Ventures)
- MIT Climate and Energy Prize — Top-12 Globally
