Life Cycle Environmental Assessment of Energy Valorization of the Residual Agro-Food Industry
2021
This study assesses the potential environmental impacts related to the energy valorization of agro-food industry waste thought the Life Cycle Assessment methodology (ISO 14040). The system examined consists of a real anaerobic digester coupled with a combined anaerobic digester and heat and power plant (AD-CHP) operating in Sicily. The analysis accounts for all the impacts occurring from the delivery of the biomass to the AD-CHP plant up to the electricity generation in the CHP. The main outcomes of the study include the eco-profile of the energy system providing electricity and the assessment of the contribution of each life cycle phase aimed at identifying the potential improvement area. …
Selection of microrganism for the mobilization of cellulolityc agricultural biomass for energy production
2012
Selection of microorganisms for the mobilization of cellulolytic agricultural biomass for energy production. R. Di Bonito, D. Taschini, C. Viola, Campi otti C.A. Unit Energy Efficiency in Agriculure, ENEA Casaccia, Roma, Italy The production of biofuels as renewable energy source could significantly reduce the negati ve impact of fossil fuels. However, this activity has resulted in increasing land cultivation specifically with carbohydrate-rich crops for energy production, and resulting shortage of crop production for food . The use of residual agricultural biomass as a substrate for biofuels or biogas production could improve the sustainabi lity of the bio-energy production but sti li requ…
Environmental assessment of energy valorisation of residual agrofood industry biomass in Sicily: a life cycle approach
2020
Anaerobic digestion (AD) uses biomass to produce biogas to generate heat and/or electricity. Several studies have reported that the adoption of AD may not necessarily lead to sustainable practices. For example, energy crops may cause significant impact due to the requirement of intensive agricultural practices. Then, residual biomasses are starting to be considered as alternative biomass for energy valorisation trough AD. In this context, this study assesses the potential environmental impacts related to the energy valorisation of agro-food industry waste though the Life Cycle Assessment methodology (ISO 14040). The system examined consists of a real anaerobic digester coupled with a combin…
Identification of Energy Hubs for the Exploitation of Residual Biomass in an Area of Western Sicily
2017
Recent years have witnessed a marked reduction in financial incentives for renewable energy production in Italy as a consequence of the fact that the nation has already reached its energy policy targets for 2020, However, incentives still persist in certain sectors, such as those of specialized crops for biomass and residual biomass. In order to increase use-efficiency of biomass resources, careful study is needed of their characteristics, and their distribution within an area and over time: biomass use is of interest when production is concentrated in a given area and sufficiently available throughout the year. In order to assess the competitiveness of the biomass energy sector, the logist…
