Takachar: decentralized and smart trash-to-cash operations


Biomass (crop/forest residues) represents a $120B/year missed opportunity for conversion into fuels/chemicals because it is often loose, wet, bulky, and difficult to transport/collect in rural areas. The biggest limitation biomass conversion technologies face today is that they often are too large-scale and operator-intensive to be deployed in decentralized areas where there is large variability in input characteristics. Using MIT patents and an IoT control system, we enable small-scale conversion of biomass into high-value, carbon-negative bioproducts such as biofuels, fertilizers, and chemicals, bringing 40% increase in income to rural farmers, and preventing air pollution and carbon footprint associated with open-air biomass burning.
