The database was created as part of Workpackage 1 of the WASTEWISE project (WASTEWISE – Waste Avoidance Strategies for Environmental Sustainability). The objective of task 1.1 of the project was to compile Food Loss and Waste (FLW) quantities from existing studies to a database to facilitate further analyses within and outside of the project. Version 1 of the database contains data from 64 sources, which were identified through literature search and personal inquiries within and outside the project consortium. Data were only included if they were collected with a methodology allowed for the EU Food Waste reporting. The database contains food loss and waste quantities on a disaggregated level of food items such as apples or tomatoes from 12 food groups and 53 food items. Composite dishes which are discarded in significant quantities in households and restaurants and food services are also included. The food waste quantities are given per food supply chain stage. The data are complemented by information on geographical and temporal scope and methodological information from the study. The food items are classified according to EFSA FoodEx 2 and CPA. The NACE codes are reported if possible. The geographical scope of the database is Europe.
