Measuring food waste: manual and smart meter based approaches Sodexo case study

2nd June 2015

Sodexo took part in a food waste monitoring trial evaluating the use of manual monitoring and smart meters at six of its UK and Ireland sites. The project was funded by WRAP as part of the Hospitality and Food Service Agreement (HaFSA).

Overall the sites achieved food waste reductions ranging from 5% to 41% savings in grams per cover from the baseline
These reductions equate to food waste savings of the equivalent of 12 tonnes per annum (tpa) across the sites or a 6% reduction in food waste per cover across all six sites

Although both the manual and smart meter approaches required time to implement, once in place, staff found the additional processes were easy to integrate into the day to day running of the kitchens. The data gathered provided valuable insights into the sources and scale of food waste and supported the identification and implementation of a range of actions to reduce food waste. The project highlighted that when introducing any food waste monitoring it is important to take time to consider set-up space and equipment integration, data accuracy, staff motivation and the impacts of introducing changes to existing practices. 

"This project has helped highlight the benefits of food waste tracking but also the challenges. Having this level of information on the two monitoring approaches will certainly aid better decision making and enhance advice provided to Sodexo sites on the best route to take in addressing food waste."
