Whether of sedimentary origin or acquired by burning wood, coal has been among the most commonly utilised energy sources for domestic and industrial uses since early humans discovered fire. The scale of consumption is growing despite industry and scientists agreeing that coal consumption is responsible for almost 40% of the carbon dioxide emissions that contribute to global warming.
"The idea of creating this came from him observing the health hazards faced by people in his community while cooking with charcoal," says Kabore, who experienced the same while growing up in the village of Koudiere, a few kilometres from the capital city of Ouagadougou. When exposed to high temperatures, this biodegradable waste undergoes decomposition, forming organic residues that are then moulded, often using water, before drying.
