Economic and environmental evaluation of transporting imported pellet: A case study

This work compares the different methods of transport used to import pellets, through a case study of pellets imported into Italy. The objective was to evaluate the economic and environmental sustainability of the different transport methods, the former via a cost analysis, and the latter via an LCA analysis. In particular, the method of transport by sea from Virginia (USA) was compared to overland transport from some European locations. Industrial pellet markets strictly depend on the import of wood pellets from outside the EU-27. The analysis of transport phase is therefore crucial, for inspecting the consequences of transporting such a commodity along considerable distances and allowing decision makers to make strategic decisions about trade planning, optimize international routes, and choose the most sustainable transport methods. The economic analysis showed that road transport cost ranged from 18 to 112 € t−1, while sea cost from 68 to 82 € t−1. Concerning the environmental evaluation, the impact categories most involved were Fossil Fuels, Respiratory Inorganics and Land Use, showing that the critical points in the transport phase are the oil consumption per km and the production of high quantities of SO2 and NOx. Basically, transport by sea appeared to be better, from the economic viewpoint, and for what concerns one of the major environmental impacts involved (fossil fuels) and primary energy consumption, compared to road transport from some of the European locations normally supplying the Italian market. On the contrary, road transport was preferred if transporting pellets from locations nearest to Italy.
