PepsiCo Produces 99% Purity Biomethane from Organic Waste

PepsiCo prevented carbon emissions equal to those removed by approximately 14,000 trees last year, thanks to its biomethanization facility in Manisa.

PepsiCo Turkey produces biomethane gas, a natural gas substitute, from organic waste (mostly food waste) at its Manisa Plant with its biomethanization facility. This project, a first in Türkiye, prevented carbon emissions equivalent to those removed by approximately 14,000 trees in 2024. In 2025, the project added a new innovation: biomethane production was increased by utilizing waste from other companies.

PepsiCo Turkey has shared the first-year results of its Biomethanization Facility project, which launched in late 2023 in line with its Pep+ strategy. The project produces biomethane gas from organic waste, which can replace natural gas used in homes and workplaces. The 7.5 million kWh of biomethane produced in 2024 prevented 1,370 tons of carbon dioxide emissions, equivalent to the carbon absorption capacity of 13,700 mature trees each year.

PepsiCo Turkey continues to reduce greenhouse gas emissions while meeting the natural gas needs of the PepsiCo Manisa Factory with biomethane gas obtained from organic waste through the Biomethanization Facility, which was implemented at the Manisa Factory as a first in the global PepsiCo ecosystem and in Türkiye.

PepsiCo Turkey General Manager Ergün Günay emphasized the importance of private sector collaboration for the environment, saying: “We started by using our own waste in our biomethanization facility. Thanks to the 7.5 million kWh of biomethane we produced in 2024, we prevented 1,370 tons of CO₂ emissions; this is equivalent to the annual carbon absorption capacity of approximately 14,000 trees. In 2025, we also began using waste from surrounding factories. Thus, we have created a pioneering collaboration model in the industry that contributes to both the environment and the circular economy. We are preventing over 1,000 tons of carbon emissions with the waste we collect from our partners.”

PepsiCo Turkey, which currently generates electricity from organic waste through cogeneration facilities at its Turkish factories, meets 35 percent of its electricity needs through the Organic Waste Processing Facilities at its food factories. It sources the remainder from solar panels and renewable electricity companies. The Manisa factory is implementing a system featuring advanced technology and engineering that produces biomethane equivalent to natural gas instead of electricity, a first in Türkiye. At the Biomethanization Facility, potatoes, chips, starch, oil, sewage sludge, and similar degradable organic waste are converted into biogas by decomposing in an oxygen-free environment for 25-30 days. This phase of the process is called Anaerobic Digestion. The resulting biogas then undergoes a series of purification processes to be made ready for use in the Metagen Unit, the plant's most important component, and is ultimately converted to 99% pure biomethane. Thanks to this process, the biomethane produced can be used as a fuel in production lines instead of natural gas.

PepsiCo Turkey's 50-person team collaborated with experts from Germany and Portugal to utilize cutting-edge technologies. Designed in accordance with the Industry 4.0 concept, the Manisa Factory is managed centrally via an automated system. The project has become a model for the PepsiCo ecosystem; implementation has begun in Portugal and plans are underway in other countries soon.
