Pivot fuel is a human waste derived granular solid biomass fuel intended for industrial applications. Pivot Works converts human waste streams in large municipalities to a solid fuel through mechanical processes providing both an energy source and sanitation solution.
Pivot Works is located in Kigali, Rwanda.
Pivot Works is the only distributor.
Industry range for a ton of solid fuel at Pivot Fuel’s energy content (18 GJ per ton) is $45 – $189 USD interview with representative
– Municipal wastewater treatment plants
– Large scale anaerobic digestion plants
Private sector and businesses in need of solid fuel
The fuel is created using three major processes: use of a belt filter, mechanical dewatering machine followed by greenhouses for solar drying, and a thermal dryer for sanitizing and homogenizing the form factor of the finished product. Human waste is brought to the process site by vacuum trucks and stored in large holding tanks.

50 tons as of June 2016 interview with representative
A municipality of roughly 1 million persons is required to achieve workable economies of scale. Climate, alternative fuels access and market price, regulatory structure, and government interest are all components needed for success. The fuel produced is a granular solid biomass fuel.
