The project will use carbon capture technology to transform potato peeling leftovers into low carbon fertiliser.
The fertiliser will then be supplied to UK farmers growing potatoes for Walkers crisps from next year, helping the brand to shrink its carbon footprint and improve soil health.
The use of fertiliser is predicted to reduce Walkers’ carbon emissions by 70%.
The technology has already been trialled on this year’s crop and used Walkers potato waste alongside carbon dioxide captured from beer brewing processes.
As the technology is rolled out more widely, PepsiCo plans to source the carbon dioxide from its own supply chain.
David Wilkinson, PepsiCo’s Senior Director of European Agriculture, said: “This is just the beginning of an ambitious journey, we’re incredibly excited to trial the fertiliser on a bigger scale and discover its full potential.
“This initiative is a step in the right direction, and we will continue working hard to lower the carbon impact of our products from field, through manufacturing sites, to consumption.”
Pawel Kisielewski, CCm Founding Director, commented: “By enabling the sustainable reuse of waste resources and the locking of captured carbon back into the soil, our partnership represents a significant step forward in proving that agriculture can play a role in carbon reduction and the circular economy.”
