In a significant step toward a more sustainable future, PepsiCo, the renowned American beverage and food conglomerate, is embarking on an innovative venture in South Africa. The conglomerate is set to construct a pioneering food waste-to-energy plant at its Simba Chips facility in Johannesburg.
This strategic initiative not only aims to combat methane emissions in the region but also reduce reliance on the national electricity grid.
PepsiCo, at the forefront of mitigating methane emissions in South Africa, has partnered with the local enterprise Tecroveer, known for its expertise in water and waste treatment solutions. Under this collaborative agreement, Tecroveer will lead the construction of an advanced facility designed to transform a substantial 11,500 tonnes of food waste, fried food remnants, and sewage sludge each year.

At the heart of this innovation is the ingenious conversion of waste materials into two valuable resources: electricity and fertilizer. Utilizing an 800 kW-capacity power plant, the waste will undergo an efficient transformation into electricity, promoting sustainable energy principles. Additionally, the facility is primed to produce fertilizer, supporting PepsiCo’s agricultural endeavors across its South African plantations.
The foundation of this groundbreaking facility rests on cutting-edge high solids anaerobic digestion technology pioneered by Anaergia. This sophisticated process orchestrates a symbiotic relationship between microorganisms and organic matter, including food remnants, solid wastewater byproducts, and even animal manure. The result of this transformative process is the production of biomethane, which can be harnessed as a renewable natural gas.
Notably, this technology, aptly named the “Omnivore” by Anaergia, is highly adaptable and efficiently processes a diverse spectrum of organic components, yielding up to three times more biomethane.
PepsiCo’s visionary approach extends beyond curbing methane emissions, a significant contributor to climate change. It addresses a dual challenge by reducing dependence on Eskom, the state-owned utility, thereby mitigating the impact of power shortages while also cutting electricity expenses. This strategic move aligns seamlessly with PepsiCo’s steadfast commitment to sustainability, strengthening operational resilience in a dynamic energy landscape.
The shift from waste to invaluable resources, exemplified by PepsiCo’s waste-to-energy plant initiative, brings numerous benefits. It reduces methane emissions, generates renewable energy, conserves resources, reduces waste volume, promotes energy self-reliance, and offers economic and environmental advantages. PepsiCo’s visionary undertaking resonates with the principles of a circular economy, designed to optimize resource utilization while minimizing the ecological footprint of human activities. This initiative represents a significant stride towards a greener and more sustainable future in South Africa.
