This paper analyses the logistics and environmental impacts of pallet pooling operations in a network serving a large-scale retailer. Pallets, as reusable transport items (RTIs), require careful management to avoid shortages and reduce the need for new production. The study evaluates various pooling scenarios by combining management strategies with different retailer network configurations. Using software with Geographic Information System (GIS) and routing capabilities, the analysis quantifies the logistical and environmental effects, showing that vehicle distances and pollutant emissions can be reduced by 65% and 60%, respectively. The paper offers insights for optimising pallet management to minimise environmental impacts and improve efficiency.
