A food waste-to-energy plant is being built at PepsiCo’s Johannesburg site in South Africa. The multinational soft drink and food giant wants to reduce its methane emissions in South Africa, as well as its dependence on the national electricity grid.
Pepsico is committed to reducing its methane emissions in South Africa. The group, which manufactures the famous “Pepsi” brand of beverage, as well as food products, is developing an energy recovery project for food waste at its site in Johannesburg. Pepsico has entrusted the work to the South African company Tecroveer, which specialises in water and waste treatment. Tecroveer will build a plant capable of converting 11,500 tonnes of food waste, fried food, and sewage sludge per year
The waste will be converted into electricity through a power plant with a capacity of 800 kW, as well as into fertiliser for Pepsico’s plantations in South Africa. The future plant will use Anaergia’s high solids anaerobic digestion technology. According to the Canadian provider of complete solutions for extracting organics from waste, anaerobic digestion is the process by which living microorganisms are mixed in a tank with organic material that we dispose of, sew or throw away, to produce biomethane.

This technology is called ‘Omnivore’, because it can digest just about anything organic; from food waste, and solids in wastewater, to animal manure to produce three times more biomethane. In addition to reducing methane emissions, one of the causes of climate change, Pepsico’s approach also aims to reduce its dependence on the South African state-owned utility Eskom’s grid, its electricity bills in a context marked by load shedding, and pollution.
