“…The Monte Carlo analysis showed that environmental profiles are likely accurate for GWP, POCP, AP and NRF impact categories [50,125]; on the contrary, ODP values have a lower confidence, probably due to the higher uncertainty related to the statistical distribution of pesticide production data. The EP category showed variable results with a greater uncertainty for organic scenarios, but lower for conventional ones.…”

Abstract:The wine sector is going through a significant evolution dealing with the challenges of competition issues in international markets and with necessary commitments to sustainability improvement. In the wine supply chain, the agricultural phase represents a potential source of pollution and costs. From the farmers' point of view, these contexts require them to be more attentive and find a compromise among environmental benefits, economic benefits, and costs linked to farming practices. This paper aims to make a sustainability assessment of different wine-growing scenarios located in Calabria (Southern Italy) that combines conflicting insights, i.e., environmental and economic ones, by applying Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) to identify the main hotspots and select the alternative scenarios closest to the ideal solution through the VIKOR multicriteria method. In particular, the latter allowed us to obtain synthetic indices for a two-dimensional sustainability assessment. Conventional practices associated to the espalier training system represent the best compromise from both environmental and economic points of view, due to the higher yield per hectare. The choices regarding Functional Unit (FU) and indicators were shown to have a high influence on results.

Despite their different scopes, both the Life Cycle Assessment (LCA) methodology and the Cradle to Cradle (C2C) Certified TM Product Standard can support companies in the implementation of circular economy strategies. Considering the case of aluminium cans, the objectives of this paper are twofold: (i) to compare the environmental impact associated with different levels of two C2C certification requirements by using LCA; and (ii) to identify the main challenges and drawbacks in the combined use of LCA and C2C for packaging within the circular economy framework.Twenty different scenarios were developed and compared, according to three C2C certification levels, in terms of % renewable energy and % recycled content. The results show that increasing the recycled content provides more improvements to environmental impacts than increasing renewable energy usage.Furthermore, receiving a higher certification level does not necessarily mean environmental burden reduction in LCA sense.From a methodological point of view, the main challenge for LCA is to address the continuous loop of materials and account for the benefits from recycling in a consistent way. Meanwhile for C2C the challenge is to guarantee a proper translation of the C2C principles into the C2C certification program, avoiding burden shifting and to find a balance between the different certification requirements.

“…This event will be of interest in order to identify if the increase in life cycle-oriented studies in Latin America not only consolidates but also diversifies to a broader number of industrial sectors. For instance, in the case of water and wastewater treatment, LCA has proved to be a very useful tool to aid policy makers and companies when it comes to improving old plants or developing new ones (Corominas et al 2013;Niero et al 2014). A proliferation of studies in this sector, which are recently being developed at a national level in many megacities across the region, as well as in solid wastes, mining, or traffic, would definitely demonstrate that the LCA community in the region is on the right track toward integrating the main productive sectors and is managing to expand and increase the number of active practitioners in the region.…”
