A prerequisite for the implementation of this strategy is the scale￢ﾀﾐspecific assessment of both the energetic performance and of the impacts in terms of greenhouse gases (GHG) emission and crop responses. This study considered the gasification process developed by Advanced Gasification Technology (AGT, Italy), which is a fixed￢ﾀﾐbed, down￢ﾀﾐdraft, open core, compact gasifier, having 350ￂﾠkW of nominal electric capacity (microgeneration); this gasifier uses biomass feedstock deriving from agricultural/forest products and byproducts. In this study, the resulting biochar, derived from conifer wood chips of mountain forestry management in North￢ﾀﾐwestern Italy, was applied to a nearby paddy rice field, located in the largest rice agricultural area of Europe. We performed a Life Cycle Analysis (LCA) adapting the BEAT2 model specifically focusing on the GHG balance of the supply chain, from the forestry management to the field distribution of the resulting biochar. The results indicated that the gasification stage had the highest impact in the supply chain in terms of emissions, but net emissions allocated to biochar were always negative (ranging between ￢ﾈﾒ0.54 and ￢ﾈﾒ2.1ￂﾠt CO2eￂﾠt￢ﾈﾒ1 biochar), hypothesizing two scenarios of 32% and 7.3% biochar mineralization rate in soil, over a time period of 100ￂﾠyears. Finally, biochar had a marginal but positive effect on rice yield, thus increasing the sustainability of this energy￢ﾀﾐbiochar chain.</p> 330 gasification 01 natural sciences 7.
