7% of global greenhouse gas emissions caused by humans come from the production and use of fuelwood and charcoal, which also contributes to deforestation. Sanivation collects human waste from special toilets and turns it into sustainable fuel, which improves sanitation and reduces the environmental impact of burning wood. The briquettes are providing people in Kenya with a more environmentally friendly and sustainable alternative to firewood and charcoal - saving trees, preventing pollution, improving sanitation and creating local jobs. Twice a week, the company collects containers of faecal sludge from around 650 specially designed toilets across Kenya and takes it to treatment facilities. It’s combined with other biomass waste like sawdust and turned into safe, hygienic fuel. Sanivation says the toilets have improved sanitation for 20,000 people, reducing diarrheal diseases. More than 1,500 tonnes of briquettes have been sold so far to factories, schools, restaurants and households.
