A survey of 204 food and beverage companies in Europe - Austria (54), Spain (47), Poland (39), Germany (28), UK (26), and France (10) - was conducted to determine consumption patterns and potentials for CO2 emission reduction based on sub sector, size and geographic location of the companies. 49 of these companies were consequently selected for in depth analysis. For these cases detailed recommendations for efficiency improvements and renewable energy (RE) integration with associated CO2 reduction potential were developed and 8 cases were consequently selected for implementation of these measures within the lifetime of the GREENFOODS project. In total, over 4,400 GWh of annual energy consumption was collected in the basic audits, with coal leading at 2,100 GWh, followed by natural gas (1,085 GWh), electricity (917 GWh), and oil (349 GWh). Results indicated that 11-19% of emissions can be reduced by undergoing retrofits in existing processing lines without significant disturbance of production. The most recommended measures are process optimization and heat recovery followed closely by solar heat use, then cold supply optimization and biomass use, and finally heat supply optimization and CHP utilization. In total, over 120,000 MWh of energy consumption was identified for reduction and CO2e mitigation, and more than 30,000 t CO2e have been identified for potential mitigation.
