The awareness of climate change and an evolving energy market lead us to look for urgent solutions. This challenge is both interesting and indispensable, considering the commitments of the European Directives n. 28 and 29 of 2009 concerning the promotion of renewable energy and GHG reduction by 2020 respectively. In this context, the use of Anaerobic Digestion (AD) is interesting in the agro-zootechnical sector and could play an important role in the ‘green economy’ as it may represent a key technology to minimize environmental impact and produce renewable energy. This paper intends to assess, using literature reviews, the overall environmental impact of biogas production system, which themselves depend on many factors. The use of AD reduces greenhouse gases, through the CO2 decrease, from the fuel replacement by generated biogas, from the avoided CH4 emissions, from animal effluent storage, N2O emissions from soil application of zootechnical waste and improved plant availability of the nitrogen in the manure. However, it is also necessary to identify and determine what mitigation measures (Best Available Techniques-BAT) should be provided to minimize potentially adverse impacts.

Abstract
The awareness of climate change and an evolving energy market lead us to look for urgent solutions. This challenge is both interesting and indispensable, considering the commitments of the European Directives n. 28 and 29 of 2009 concerning the promotion of renewable energy and GHG reduction by 2020 respectively. In this context, the use of Anaerobic Digestion (AD) is interesting in the agro-zootechnical sector and could play an important role in the ‘green economy’ as it may represent a key technology to minimize environmental impact and produce renewable energy. This paper intends to assess, using literature reviews, the overall environmental impact of biogas production system, which themselves depend on many factors. The use of AD reduces greenhouse gases, through the CO2 decrease, from the fuel replacement by generated biogas, from the avoided CH4 emissions, from animal effluent storage, N2O emissions from soil application of zootechnical waste and improved plant availability of the nitrogen in the manure. However, it is also necessary to identify and determine what mitigation measures (Best Available Techniques-BAT) should be provided to minimize potentially adverse impacts.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
