The WASTELESS project will develop and test a mix of innovative tools and methodologies for Food Loss and Waste (FLW) measurement and monitoring. A bottom-up approach will be followed: starting from defining an harmonised methodological framework and set of standards for the testing activities, the evaluation of the tools implementation and the quality and integrability of the data produced in other frameworks and finally recommend sustainable policies and business strategies to set the ground for a harmonised Framework at EU level. Additionally to the measurement and monitoring tools, WASTELESS will carry research activities on innovative processes and streams to valorise unavoidable FLW. With the ambition to make existing FLW quantification solutions and WASTELESS ones usable by all food actors, it will be developed a Decision Support Toolbox for any stakeholders to access to the most appropriate methodology, digital tools and solutions for FLW valorisation all that aggregated with the Environmental and Socio-Economic impact associated to the implementation of the solutions. This will enable the replication of data collection hubs accross Europe feeding the model developed by JRC with robust, reliable and comparable FLW data.
