The implementation of scientific studies can help to improve sustainable solutions in the agri-food sector according to current European policy. The present paper aims to evaluate the carbon footprint, according to ISO/TS 14067:2013, of 0.5 kg of sweet cherries packaged in clamshell made in polyethylene terephthalate (PET). The research assesses the supply chain, from agricultural (from nursery to dismantling) to the processing phase in firms located in the Apulia region. Results show a global warming potential over a fixed period corresponding to 100 years equal to 0.584 kg CO 2eq , primarily deriving from agricultural management (0.442 kg CO 2eq) and secondly from fruit processing (0.068 kg CO 2eq). In the orchard phase, the main impacts derived from electricity consumed to pump groundwater used for irrigation and fertigation activities (15.84% of the total), transportation of manure (6.42% of the total), ploughing activity (4.83% of the total) and production of nitrogen fertilisers (4.28% of the total). Cherries processing in the collecting centre showed impacts from electricity consumption (5.57% of the total) and from waste deriving from damaged or non-conforming cherries (4.74% of the total). The PET clamshell production phase had an impact deriving principally from the use of PET granulate (0.0743 kg CO 2eq). The study highlighted that manure administration and pruning activities contribute to decreasing greenhouse gas (GHG) emissions. Moreover, the sensitivity analysis showed that substitution of electricity-mix deriving from the Italian national grid with a photovoltaic plant lowered GHG emissions by 19%. The present study could contribute in providing suggestions to stakeholders and scholars in reducing GHG emissions and promoting more environmentally sustainable sweet cherry production practices. Image 1 • Increasing knowledge on the CF assessment of the sweet cherries supply chain. • A case study of sweet cherry production located in Southern Italy was examined. • Carbon Footprint assessment was applied to 0.5 kg of sweet cherry in PET clamshell. • Results show that GWP 100 is equal to 0.584 kg CO 2eq. • Main impacts deriving from agricultural activities (75%) and fruit processing (12%).

The recent climate change, global warming, environmental disasters and the economic crisis are only the first signs of the failure of an economic system that, for too long, shows an uncontrolled utilization of the planet wealth. The Italian electricity market, which is strongly dependent on hydrocarbons, only in recent years has seen a first attempt to change towards renewable resources for electricity production aimed at self-consumption and for feeding into the grid. This paper presents an economic analysis whose purpose is to evaluate the profitability of investments in renewable technologies for the production of electricity. Each renewable source has its own profitability dependent on a number of factors and subject to market fluctuations, cost and frequent changes in the incentive policies. Applying Portfolio Theory is possible to select the right mix of renewable energy sources and simulate its evolution. Moreover the presented analysis can be useful for energy planners to select future green scenarios finalized to the reduction of emissions and energy imports through the increasing use of renewable energy.

The aim of the paper was to evaluate the environmental burden of the organic waste management systems implemented in Umbria region in Italy, in order to provide useful information for taking strategic decisions aimed at the improvement and optimization. The two most widespread scenarios were analyzed: source-segregated collection followed by organic fertilizer production and not-differentiated collection followed by mechanical and biological treatment and disposal in landfill of the biostabilized material. The environmental performance was assessed through Life Cycle Assessment methodology, assuming one ton of organic waste as functional unit. Most of data for life cycle inventory were provided by actual facilities while background data were obtained from EcoInvent database. The alternative scenarios were compared through the IMPACT 2002+ method and the assessment was carried out on both midpoint and endpoint levels. Results showed that the landfilling of the undifferentiated organic waste has the least impact on the analyzed impact categories, except on the Global Warming, mostly due to the uncollected methane released by the landfill. As regards the aerobic composting of the source-segregated organic fraction, the efforts to reduce the impact should be mainly focused on the reduction of the air emissions (hydrogen sulfide, particulate, ammonia and NMVOC) from the biostabilization process. Furthermore the sensitivity analysis indicated that the increase of the biogas collection efficiency could significantly improve the performance of the not-differentiated collection scenario.
