SummaryThe concept of eco-efficiency can be defined by using the "product value/environmental influence" ratio. Different models have been proposed to measure eco-efficiency. The main difference among them is the weighting system used to aggregate the environmental results. Data Envelopment Analysis (DEA) permits this aggregation without requiring a subjective judgment about the weights. In this study, a DEA model was applied to Spanish Mahón-Menorca cheese production to determine the most eco-efficient production techniques.To this end, 16 scenarios of Mahón-Menorca cheese production were built regarding technical (degree of automation) and cleaner production criteria. The environmental impacts were assessed by means of the Life Cycle Assessment. An economic assessment was carried out by determining the economic value added and the net income for each scenario. The results are referred to as 1 kg cheese ripened over 105 days.By using DEA, an eco-efficiency ratio lying between 0 and 1 was obtained. Three scenarios were found to be eco-efficient, using a high degree of automation (enclosed vat and molding and demolding machines) and accelerated cheese ripening.The Montecarlo simulation was used to carry out a sensitivity analysis to compare the influence of price changes on the eco-efficiency ratio. The results emphasized the consistency and stability of the eco-efficient scenarios. IntroductionAccording to the results from a study financed by the European Union (EU), one of the product groups with the highest environmental impact throughout its entire life cycle is foods, especially dairy and meat products (Tukker et al. 2006). For this reason, food production systems need to be rethought in order to be more environmentally friendly.The food industry is one of the main contributors to discovering new solutions and, therefore is highly relevant. In this context the role of cleaner production techniques must be emphasized since they have a pro-active focus instead of a reactive one. They have the potential to reduce emissions and waste produced in the production process and, consequently waste treatment. Nevertheless, establishing the best available techniques requires that not only the environmental aspects, but also the economical ones, be taken into account. The eco-efficiency concept embraces these two aspects.Eco-efficiency of production concerns the capability to produce goods and services while causing minimal environmental degradation. According to World Business Council for Sustainable development (WBCSD 2000), eco-efficiency is represented by the ratio "Product or service value/Environmental influence". Kuosmanen and Kortelainen (2005) consider the eco-efficiency concept to be critically important for at least two reasons: (1) it is often the most effective way of reducing environmental pressures; (2) policies targeted at efficiency improvements tend to be easier to adopt than policies that restrict the level of economic activity. The ecoefficiency concept and the search for eco-efficie...

The investigation of scientific documents in the area of knowledge of the conservation and restoration of cultural assets forms an intrinsic part, as defined in its title, the subject of the Master's Degree in Conservation and Restoration of Cultural Heritage, "Resources for research and scientific documentation”. It is intended to activate reflection and critical analysis in the subject in an incipient way in the study of the relationship between the conservation and restoration of cultural assets and gender, after the interpretation of the resources used in scientific research, in this way it is undertaken initiate and provide students with new tools where the role of women restorers and their scientific contributions in the field of conservation and restoration of cultural assets are identified and valued. To carry out this initiative, a specific practice will be developed through the reference manager, Mendeley, where the search for female authors will be addressed to value their studies through the corpus of their texts, monographs, articles, reports, manuals of reference, in relation to the theme or period of study of the activity in question requested as a learning object.
