Pepsico Food Waste Digestion Unlocks Energy Potential in South Africa via Anaerobic Digestion
At PepsiCo South Africa's Isando facility in Gauteng, food waste does not go to rubbish dumps. They use a Food Waste Anaerobic Digester to turn their garbage into biogas instead of letting it rot away unused.
This process gives the plant clean energy and even cuts carbon emissions by capturing methane before it escapes.
PepsiCo South Africa describes its Isando facility in Gauteng as a “beacon of sustainable innovation,” with an on-site anaerobic digestion system that converts trash into biogas and generates up to 30% of the site's peak energy needs.
This comes after the firm introduced its new potato chip production line, the PC50 Flex Line, in which it invested R746 million last year.
PepsiCo referred to the plant as the “cutting edge” of South Africa's snack production scene.
Isando, which manufactures brands such as Lay's, Simba, NikNaks, and Doritos, is stated to exemplify PepsiCo's dedication to world-class production, environmental responsibility, and local economic empowerment.
Gareth Haarhoff, General Manager of PepsiCo South Africa Snacks, described the local snacks business as resilient, with consistent increase in volume and income over the last decade.
This blog will explain how anaerobic digestion transforms uneaten snacks, potato peelings, and other organic materials into power. You will also learn how this site helps create jobs while cutting pollution with its new renewable natural gas system.

PepsiCo's Sustainability Measures in Isando, Gauteng
PepsiCo runs an on-site biogas system that turns food wastes into renewable energy. This plant cuts down landfilling, lowers carbon dioxide output, and improves waste management at the Isando facility.
On-site Anaerobic Digestion Plant
Inside the Isando facility, massive anaerobic digesters hum quietly behind secure gates. Workers feed around 30 tonnes of food waste and other organic wastes into these biogas systems each day.
As a result, bacteria break down biodegradable materials without oxygen. This natural process releases methane gas, sometimes called swamp gas or CH4, which powers turbines to produce electricity for the plant.
The on-site sewage treatment plant does more than just manage waste; it sequesters carbon and shrinks landfill needs by turning food wastes and biosolids into clean energy. Up to 30 percent of the site's peak electricity demand now comes from this renewable energy source.
The R100-million investment in this project included R16.8-million from South Africaâ's Critical Infrastructure Programme grant through the Department of Trade, Industry and Competition.
Workers see big change in daily routines to no more trucks hauling decaying leftovers off-site for landfilling or incineration. Instead, digestates left after methanogenesis work as fertiliser for agriculture nearby.
They help keep water quality high and also reduce pollution risks linked with traditional mixed waste disposal methods at wastewater treatment facilities or incinerators elsewhere.
It's like swapping fossil fuels for cleaner bioenergy every single day while cutting that carbon footprint at snack speed!
Renewable Energy Generation Capacity
PepsiCo plans to ramp up its renewable energy solutions at the Isando site by the end of next month. The expanded capacity will hit 2.5 megawatts, making a real difference in lowering reliance on fossil fuels.
A sturdy 800 kilowatts of this power comes straight from the anaerobic digester, which gobbles up food waste and animal manure, producing biogas as clean energy for operations. This process cuts down landfill use and supports South Africa's push for pollution prevention.
Solar panels already cover existing roofs and soak up daylight like sunflowers stretching their heads. They produce about 1.7 megawatts of solar electricity right now, feeding sustainable energy into snack production lines every day.
Any extra gas from digestion may be used as compressed natural gas or even biomethane in alternative-fuel vehicles, ticking more green boxes for PepsiCo's sustainability drive.
The company uses codigestion technology at their biorefinery plant where greases, yard waste, dung and even sewage sludge join food scraps on the menu for microbes hard at work creating methane (CH4).
By using these methods instead of landfilling leftovers or letting them rot unchecked, Pepsico boosts both gas production and clean water reclamation through WWTP efforts, like recycling, but with extra wattage!

Pepsico Food Waste FAQs
1. How does Pepsico's food waste anaerobic digestion work in South Africa?
Pepsico sends leftover food to a treatment tank, not the landfill. Microbes break down this waste without air. This process creates gas, including hydrogen sulfide and water vapour. Some of that gas is recycled for energy.
2. What role do sewage plants play in this process?
Sewage plants often use Upflow Anaerobic Sludge Blanket reactors, or UASB tanks, for treating wastewater like this. These tanks help clean both sewage and industrial wastewater by breaking down organic material.
3. Why avoid sending food waste to landfill sites?
Landfilled food rots and releases methane into the air; it harms the environment and wastes potential fuel. Digestion captures useful gases instead.
4. Can you explain what happens to hydrogen sulphide during treatment?
Hydrogen sulphide forms as microbes digest waste in these systems; it needs careful handling because it smells bad and can be harmful if released unchecked during recycling steps at sewage works or other facilities using similar technology.
