High-resolution electricity generation mixes in building operation: A methodological framework for energy and environmental impacts and the case study of an Italian net zero energy building.

Temporal fluctuations of the electricity grid generation composition, variability of electricity consumption in building operation over the year and of the on-site renewable energy systems are factors that should be properly considered, using high-resolution data in the building energy and environmental performance assessment. In this study a methodological framework is developed to model high-resolution electricity mixes in building operation and to assess the related energy and environmental impacts over the year, by means of a life cycle approach. For most impact categories, the imported electricity generation mixes, to meet the residual building demand, show impact variations not higher than +20 % and not lower than -38 % at seasonal and daily time compared with the annual average values.

Bioenergy from anaerobic digestion plants: Energy and environmental assessment of a wide sample of Italian plants.

This study assesses the energy and environmental performances of electricity produced from Italian anaerobic digestion coupled with combined heat and power plants. The Life Cycle Assessment methodology is applied to a set of plants characterised by different power sizes (from 100 to 999 kW) and feedstock compositions (variable rates of agricultural products and by-products). Then, the average eco-profile of the produced electricity is compared with electricity produced by the national grid and photovoltaic panels.

Energy-environmental assessment of the UIA-OpenAgri case study as urban regeneration project through agriculture.

Sustainable agriculture is strongly promoted by Agenda 2030 and peri-urban agriculture is considered strategic for agri-food sustainability. Although, innovative farming practices are being implemented, the analysis of their impacts often does not reach the required depth. Within the EU project 'UIA-OpenAgri - New Skills for new Jobs in Peri-urban Agriculture', a regeneration process of a peri-urban area in Milan (Italy) was started, through the development of an innovative food hub.

Life cycle assessment of olive oil: A case study in southern Italy.

The paper describes the results of a specific LCA based analysis of the production of olive oil in the region of Calabria, in southern Italy. The goal of the study is to assess the energy and environmental impacts of different scenarios involving conventional and organic cultivations, plains and hills cultivations and involving different operating techniques. The study also aims at assessing the share of each life cycle step on the total of energy and environmental impacts.

Energy and environmental life cycle assessment of an institutional catering service: An Italian case study.

Food production is recognised as one of the major drivers for global environmental pressure. In the last years, changes in consumption models result in an increasing population consuming food out of home that pose the catering service sector at the centre of the European Union policies aimed at improving the environmental sustainability of the food sector. In this framework, better technical knowledge on the environmental impacts of catering service is essential in order to identify potential actions towards a more sustainable food sector.

Life cycle assessment of Italian citrus-based products. Sensitivity analysis and improvement scenarios.

Though many studies concern the agro-food sector in the EU and Italy, and its environmental impacts, literature is quite lacking in works regarding LCA application on citrus products. This paper represents one of the first studies on the environmental impacts of citrus products in order to suggest feasible strategies and actions to improve their environmental performance. In particular, it is part of a research aimed to estimate environmental burdens associated with the production of the following citrus-based products: essential oil, natural juice and concentrated juice from oranges and lemons.

Life cycle assessment-driven selection of industrial ecology strategies.

The paper presents an application of the Life-Cycle Assessment (LCA) to the planning and environmental management of an “eco-industrial cluster.” A feasibility study of industrial symbiosis in southern Italy is carried out, where interlinked companies share subproducts and scraps, services, structures, and plants to reduce the related environmental impact. In particular, the research focuses on new recycling solutions to create open recycling loops in which plastic subproducts and scraps are transferred to external production systems.

Resource consumption and environmental impacts of the agrofood sector: life cycle assessment of italian citrus-based products.

Food production and consumption cause significant environmental burdens during the product life cycles. As a result of intensive development and the changing social attitudes and behaviors in the last century, the agrofood sector is the highest resource consumer after housing in the EU. This paper is part of an effort to estimate environmental impacts associated with life cycles of the agrofood chain, such as primary energy consumption, water exploitation, and global warming.
