Pivot Works

The waste treatment plant on Nduba mountain served as a pilot project to demonstrate to the city of Kigali the impact and viability of Pivot's processes and technology.

Andrew's primary responsibilities at Pivot Works included designs for full-scale plant, as well as designing and prototyping new tools for more efficient sludge drying. Andrew's focus at the Nduba plant consisted of engineering and operations during the greenhouse and thermal dryer phases. Andrew lead a team of four operators and together they built, tested, commissioned, and operated 1300m² of greenhouse drying space as well as a thermal dryer which caps the process of creating fuel by completing the drying, pulverizing, and sterilization. In addition, Andrew has designed and installed most of the electrical systems in the plant, and optimized different processes to reduce the cost of fuel and increase its throughput in order to make the plant more economically viable.

Andrew also spent time with potential customers performing fuel burning trials with various industries such as textiles, agriculture, and construction. With its comparatively high energy density, PivotFuel is quickly becoming the preferred choice over other options like sawdust and coffee husks.
