Varaha's biochar project addresses the ecological impact of invasive Prosopis juliflora across Rajasthan and Gujarat, India. Through an artisanal method, biochar production transforms this invasive species into a soil amendment, sequestering CO2 emissions and promoting grassland restoration.

Artisanal biochar is produced using small-scale, often traditional methods accessible to rural communities. Biochar is a charcoal-looking, carbon-rich substance that is produced when materials like agricultural residues are heated in a process called pyrolysis.
