From Waste to Wealth: Powering Africa’s Sustainable Future | Peter BenHur Nyeko

What if the secret to lifting millions out of poverty is not hidden in high-tech laboratories or multi-billion-dollar aid packages, but buried in the discards of everyday rural life?

In this episode of Brown Business, and part of our Member stories, Peter BenHur Nyeko, co-founder of Mandulis Energy, demonstrates that true global impact begins by rethinking what society leaves behind. His work is anchored in an old adage his grandmother taught him in northern Uganda: “Buru onyualo mach”, meaning the ashes give birth to fire. While the modern world habitually discards waste as valueless, Peter BenHur sees agricultural castoffs as an untapped powerhouse that can transform rural economies from the inside out.

After training as an aerospace engineer in the United Kingdom and designing aircraft and spacecraft systems, Peter BenHur realised that the fuels driving modern aerospace originally came from organic plant matter. Returning to Uganda, he applied that exact realisation to the agricultural heartland. Rather than letting farmers burn crop residues in their fields, Mandulis Energy purchases agricultural waste, from rice husks and maize cobs to groundnut shells and coffee husks.

The dry material undergoes gasification to generate fuel for clean, reliable electricity, while wet organic waste is digested to yield biogas and carbon-sequestering byproducts. The remaining nutrient-dense slurry and biochar are reconstituted into potent organic fertilisers and returned to the farmers. This closed loop transforms what was once an environmental hazard into a thriving economic engine: farmers gain a secondary income stream from crop waste, receive drought-resilient organic fertiliser to boost future crop yields, and gain access to reliable village-level power.

Scaling this vision demanded unconventional market thinking. When Peter BenHur first introduced electricity to communities that had never experienced a modern power grid, it priced power at zero. This deliberate strategy allowed rural households to phase out costly, hazardous fuels like kerosene and diesel while experiencing the direct economic and educational utility of continuous energy. Within two years, the community fully recognised its commercial value and requested a transition to metered billing. Today, power is delivered at rates well below national regulatory caps, yet consumption keeps climbing. Formerly quiet rural farming areas have reversed migration outflows, welcoming back younger generations and expanding into vibrant, micro-industrial hubs.

For Peter BenHur, solving modern infrastructure challenges does not require inventing brand-new technologies out of thin air. The foundational methods of bio-gasification have existed for generations and are proven across the Global South, from Patna and Baroda to East Africa. The true roadblock is an entrenched fear of institutional change. Genuine sustainability is not mere charitable benevolence; it must be an integrated model of environmental, economic, and social self-reliance where infrastructure pays for itself. Realising this vision demands courage from public officials, financiers, and corporate leaders to rewrite outdated policies and view waste not as a liability, but as a catalyst for exponential, shared prosperity.

The blueprints for an equitable, electrified future are already within reach, waiting in the very ground we stand on. Listen to the full episode and reclaim your fearless inner innovator, look beyond traditional frameworks, and turn neglected resources into engines of progress to champion sustainable innovation in your own community.
