Takachar is a company focused on transforming agricultural waste into valuable products, particularly eco-friendly cooking fuel. Operating primarily in Kenya, it has developed low-cost technologies that enable the conversion of unmanaged agricultural residues into charcoal, a non-toxic and affordable energy source for low-income households. Over the past three years, Takachar has established or assisted seven locally run waste-to-charcoal enterprises, some of which have achieved operational profitability. The company has successfully created approximately 100 jobs and sold 50 tons of its eco-char product. By utilizing oxygen-lean torrefaction reactors, Takachar helps farmers reduce waste through recycling, allowing them to generate additional income while preventing open burning of agricultural residues. The company aims to demonstrate the financial sustainability of these enterprises as a foundation for expanding its franchise network in the future.
