Turning corn cob agricultural waste into a cooking fuel that combats deforestation and indoor air pollution.

MIT's D-lab developed a method to turn agricultural wastes into affordable smokeless fuels, such as sugarcane charcoal and corn cob charcoal. This agricultural waste charcoal has the potential to combat deforestation and reduce the dangerous effects of indoor cooking fires. One limiting factor in the adoption of this technology is the need for a charcoal crusher.

Burning carbonized cobs produces less smoke than regular biomass fuels, but the carbonized cobs produce a hazardous level of carbon monoxideW. D-lab developed a device to turn charcoal powder into a dense compact briquette that burns safely, but it is difficult to crush the carbonized cobs into a charcoal powder without inhaling dangerous amounts of charcoal dust. Our team's charcoal crushing device addresses the gap in this alternative fuel process.
