Turning crop waste to fertilizer could fight air pollution in India

Earthshot winner, Takachar has developed a cheap, small-scale, portable technology that attaches to tractors in remote farms. The machine converts crop residues into sellable bio-products like fuel and fertilizer. This technology reduces smoke emissions by up to 98% which will help improve the air quality that currently reduces the affected population’s life expectancy by up to 5 years. If scaled, it could cut a billion tonnes of carbon dioxide a year: a win for India’s farmers will be a win in the fight against climate change.
