This study focuses on the environmental impact assessment of wood pellet production through Life Cycle Assessment (LCA). In particular, the aims are to compare the environmental impacts of ‘‘A1 premium’’ wood pellet manufacturing in a large industrial plant with “domestic” wood pellet manufacturing in a small pelletiser, and to identify the environmental hotspots of these two pellet productive chains. The results underline the fact that electricity consumption due to machinery used for the compressing phases of pelletising process plays a key role in the environmental profile, together with pellet burning. The production of the wood (forest stage) has a low impact (no more than 20%) if compared with the other main stages of the pellet life cycle (pellet production and pellet use). The comparison between the domestic and industrial model shows that, the domestic model performs better on 6 of 8 impact categories.

Abstract
This study focuses on the environmental impact assessment of wood pellet production through Life Cycle Assessment (LCA). In particular, the aims are to compare the environmental impacts of ‘‘A1 premium’’ wood pellet manufacturing in a large industrial plant with “domestic” wood pellet manufacturing in a small pelletiser, and to identify the environmental hotspots of these two pellet productive chains. The results underline the fact that electricity consumption due to machinery used for the compressing phases of pelletising process plays a key role in the environmental profile, together with pellet burning. The production of the wood (forest stage) has a low impact (no more than 20%) if compared with the other main stages of the pellet life cycle (pellet production and pellet use). The comparison between the domestic and industrial model shows that, the domestic model performs better on 6 of 8 impact categories.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
