Analysis of Waste Trends in the European Union (2021–2023): Sectorial Contributions, Regional Differences, and Socio-Economic Factors

Food waste is a chronic and ongoing environmental, economic, and social problem in the European Union. The study will examine trends in food waste from 2021 to 2023, sectoral effects, regional heterogeneity, and socio-economic determinants of waste intensity. Interlinking longitudinal data from Statista and Eurostat, statistical modeling, and cluster analysis are employed by the study to uncover trends in food waste across member states in the EU. The research shows that domestic food wastage remains the leading one, accounting for 50–60% of the total food wastage in the EU. Inefficiencies in manufacturing and retail are identified as important drivers of wastage generation in high-waste nations such as Cyprus and Denmark because inefficiencies in the processes result in increased wastage generation. Spain and Croatia have continued to record low food wastage per capita owing to good wastage management policies and consumer practices. Regression analysis identifies domestic food wastage, manufacturing waste, and retail wastage as the main drivers of total per capita food wastage, with per capita GDP (Gross Domestic Product) and carbon footprint playing weak roles. Cluster analysis places EU countries into three groups: low-waste countries with highly structured food systems, moderately-waste countries where food wastage at domestic levels prevails, and high-waste countries where there is inefficiency at food production, processing, and consumption levels. These findings necessitate specific interventions. Policy needs to address food waste minimization at the household level via consumer awareness and behavior change initiatives and remove inefficiencies in the manufacturing and retail value chains through the simplification of inventory management, redistribution chains, and incentive regulation. Regional, rather than one-size-fits-all, EU-wide policy is required in order to achieve significant progress.
