    Technical and economic evaluation concerning the different employment of marc

    Marc can represent about 20-30% of the mass of grapes destined to the wine making; marc waste is obtained after the distillation phase of marc, and in Abruzzo, which is the fifth Italian producer, its quantity can reach 60-65 kilotons. In consideration of the availability of this kind of biomass, we have supposed the installation in the province of Chieti of a 12 MW electric power station needing about 130 ton/year of biomass, 75% of the total amount deriving from the distillation process. This work carried out a technical and economic evaluation concerning the investment required to realize such a biomass power plant. The Distilleria D’Auria, the only distillery in Abruzzo, can treat about 60 tons of marc, that is, less than that needed amount. We have found that the integration is necessary with further quantity of forestry or agro-industrial biomass coming from the neighbouring regions. If we consider the future interruption of incentives regarding the alcohol production, and the ongoing support given to encourage the production of energy from renewable resources, we can observe that the integration of the two plants (distillery and power station) is the most advantageous choice in order to minimize the effects of change introduced by the distillation support policies

    Water and Carbon footprint perspective in Italian durum wheat production

    Agriculture has a strong influence on water consumption; the scarcity of water in some areas is a problem, which affects the balance of entire production areas. Global water resources are widely used for food production; some areas of the Mediterranean are scarce in water and the water demand is expected to increase in the future due to population growth. In addition, carbon emissions related to agricultural production represent about 35% of total greenhouse gas emissions. Starting from these considerations, this study investigates water and carbon footprint in italian durum wheat cultivation, taking into account the production from 2011 to 2015. Results showed an extreme variability of these indicators across the country. The regions below 5000 m3 ha−1 of water consumption (dedicated to durum wheat production) are located in the South, whilst the highest values are recorded in the Centre and in the North. With regard to the values of the water surface consumption, the situation is quite the opposite: indeed, these are mainly the Southern and the Adriatic regions that have a high value of the ratio between water footprint (WF) and total agricultural area. carbon footprint (CF) showed a similar trend; its highest value was found in Northern Italy (2462 kg CO2 ha−1), the ratio between the North and the Centre-North is 1.30. Policy suggestions that address management of water resources and sources of carbon emissions could increase the environmental sustainability of italian durum wheat production

    Carbon footprint of extra virgin olive oil: A comparative and driver analysis of different production processes in Centre Italy

    In this research, five case studies located in Abruzzo (Italy) were analysed using the Carbon Footprint method aiming primarily to quantify the greenhouse gas emissions related to the cultivation of olives and the production of olive oil (respectively farm phase and mill phase) and to identify the drivers behind these emissions (excluding olive tree planting and distribution phase). In respect to the existing literature, the research presented here developed more detailed collection of data on farms and selected the case studies in order to represent the current production situation at the international level (Spain excluded) as regards technology and size. Furthermore, an uncertainty and sensitivity analysis was performed in order to assess the robustness of results. Five litres of extra virgin olive oil, with primary and secondary packaging, were chosen as a functional unit. Results showed that agriculture accounts for emissions of CO2eq ranging from 3.34 to 7.74 kg (mainly due to fertilizer and pesticide treatments), followed by the packaging process in the industrial phase for which CO2eq emissions range from 1.13 kg to 3.20 kg (for which glass bottles represent the largest load). The study revealed that a realistic reduction of greenhouse gas emissions should be based on an efficient use of pesticides and fertilizers. Drivers are mainly located in the farm factory phase, which is the one with the highest impact, but also the phase that proves most difficult as regards retrieving detailed data

    Installazione di una centrale elettrica a biomasse alimentata con vinacce. Studio di fattibilità tecnico-economica

    I quantitativi di vinacce esauste in Abruzzo raggiungono le 60-65 ktonnellate. Sulla base della disponibilità di tale biomassa è stata ipotizzata l'installazione di una centrale elettrica da 12 MW di potenza, per il cui funzionamento sono previste circa 130kton/anno di biomassa. La Distilleria D'Auria, unica realtà presente in Abruzzo, riesce a trattare circa 60 kton di vinacce. E' necessaria quindi l'integrazione con ulteriori quantità di biomassa proveniente dal territorio circostante. L'integrazione dei due impianti risulta essere la scelta più vantaggiosa per minimizzare gli effetti dei cambiamenti delle politiche di sostegno al settore della distillazione

    PRODUCT ENVIRONMENTAL FOOTPRINT IN THE OLIVE OIL SECTOR: STATE OF THE ART

    No full text
    As a part of the development of the Environmental Footprint (EF) guidelines, in June 2014 the European Commission started 11 pilot projects for the development of Product Environmental Footprint Category Rules (PEFCRs) for food, feed and beverage products. The PEFCRs are developed by technical secretariats involving various stakeholders from industries, academia, governments, trade unions and non-governmental organisations. This paper presents the state of the art of developing the PEFCR for the olive oil sector. The functional unit is defined as a litre of packed olive oil and the system boundaries cover the whole supply chain from cradle-to-grave. A screening study that estimated the EF of the average olive oil consumed in the European markets showed that olive production phase had the highest contribution to most environmental impact categories. The results of the screening study provide a benchmark that will be further adjusted after the current draft PEFCR will be tested in case studies for real products
