This study examines the relationships between the sizes of Coop Alleanza 3.0 retail outlets and indicators (in value) of surplus food (SF), real food donation (FD) and potential food waste (FW) from 2013 to 2019.
Retail outlets were grouped by size class and geographic macro-area. The authors adopt a procedure composed of Kendall's tau-b coefficient with ties (ttest) and the coefficient of determination (R²). The authors studied bread, pastries, fruits and vegetables as representative food categories.
Among the hypermarket group (Emilia-Romagna Region and those in group with Apulia Region), the study found the t-test with many high negative relationship and related R2 high. Results showed that size significantly influenced the trends of the indicators for the food categories analyzed. This allowed the authors to hypothesize the presence of inefficiencies in these groups.
From a practical point of view, the procedure can provide Coop Alleanza 3.0, with a dashboard to analyze surplus food management (SFM) progress within its retail groups. This can provide a warning signal (WS) to trigger a management control system. If necessary, it can lead to corrective measures, such as internal optimization, by adopting appropriate work procedures. In this sense, the procedure is scalable and transferable at the international middle and micro-scales. This approach facilitates the transition to a retail circular economy transition.
The authors would like to thank Mr. Mario Cifiello (President) and the Department of Social Policy of Coop Alleanza 3.0 for the collaboration received, who provided authors with datasets and support for clarification.
