Supported by the professional division of Miele, the global foodservice retailer is adapting the washing machines used in every McDonald’s Restaurant across the country to enable the extraction of grease and fats and minimise drainage issues and disruption to local communities.

The modified Miele ‘Little Giant’ washing machines are now standard across almost all 1,300 McDonald’s Restaurants in the UK, used to launder all mopheads and cleaning cloths on site. Using the grease recovered from these wash cycles, McDonald’s Restaurants has also been able to increase its biofuel production.

McDonald’s Restaurants has been installing specialist grease recovery units (GRUs) for several years. However a typical 85 degrees Celsius grease removal wash cycle would deposit grease and fat into a GRU at high temperatures, reducing its ability to separate and be extracted. So, Miele Professional also developed a bespoke and redesigned wash cycle using lower temperatures to allow the grease to be recovered more efficiently, without compromising on hygiene. This allows the grease to be collected more easily, extracted and used towards the production of vehicle biofuel. The full rollout of the new programme is expected to take place over the next 12 months.

The partnership between McDonalds and Miele Professional


Dave Holden, building services consultant at McDonald’s Restaurants commented, “Miele continues to assist us with our washing requirements to make our grease recovery process more effective and help McDonald’s Restaurants become more sustainable as a company. The introduction of the GRU has enabled us to service more of our vehicle fleet with biofuel and with further modifications we expect this to increase further.”

Simon Hart, national account manager at the Professional Division of Miele commented, “It’s been a privilege to work alongside McDonald’s Restaurants as their sole supplier of washing machines for the last ten years. We have several exciting developments in the pipeline to further optimise the grease recovery process.”
