Toxic and essential metals determination in commercial seafood: Paracentrotus lividus by ICP-MS

Toxic and essential metals content was determined by inductively coupled plasma mass spectrometry in commercial sea urchins samples from the Mediterranean Sea and Pacific Ocean. Results show that Chilean samples have the highest values of Cd, As, Ni, Cr and V; Spanish samples have the maximum Hg content while Sicilian samples have the lowest content of toxic metals. The toxic metal traces were compared with the limits of European Community (EC) No. 1881/2006 for bivalve molluscs. All samples exceed Pb and Cd limit levels; regarding Hg levels, only Sicilian and Sardinian samples have Hg content below the EC limits. The dietary intake of toxic and essential elements was evaluated for an adult. Furthermore, our study highlights a correlation between the toxic elements content and the marine environmental conditions of the places of origin even though only the generic FAO fishing area is specified.

Household food waste and eating behavior: empirical survey

Purpose In the food chain the identification of household food wastes represents the most problematic aspect to analyze: both as regards the assessment of its qualitative and quantitative aspects and for the detection of measures to reduce or control its generation. In 2012, in fact, the analyzed area showed an inequality index for disposable income of 6.3, and a relative poverty risk index of 42.3. The paper aims to discuss these issues. Design/methodology/approach In order to get deeper insights into consumers’ wasting behaviors, a survey on food waste generation in households was carried out in a province of Sicily (Italy). The questionnaire has been formulated taking into account the socio-demographic characteristics for the person who, in the family, usually makes the expenditure, in particular: gender, age, marital status, number of household members, education level, type (single, with or without children, married with or without children), worker and/or student if responsible for food shopping, the number of monthly meals, the kind of ready meal eaten (frozen, fresh, canned or freeze-dried), net monthly income for the family, etc. (adapted by Bae et al., 2010). The data collected from the statistical return of the consumers were drawn up to transform the same data into information of simpler and more concise interpretation. Findings The results of the survey are presented in this paper. They can help understand the reasons for discarding edible food and to identify the food groups that are most wasted. Research limitations/implications The analysis of a larger land area or community allows most relevant conclusions. The research has an exploratory perspective since the sample strategy is not probabilistic. Social implications The findings could be susceptible to support practical and social implications for the identification of measures and instruments aimed at reducing food waste and at increasing consumers’ awareness on that issue. Originality/value The study can stimulate sustainable consumption and consumer behavior especially in light of the current economic crisis.

Assessment of milk consumer preferences: Identifying the choice factors through the use of a discrete logistic model

Purpose The purpose of this paper is to report a survey in random-selected supermarkets in Italy in order to identify the attitudes and perceptions of consumers toward milk and in particular toward donkey milk. Design/methodology/approach The analysis was conducted through Google Forms platform of docs.google interviews with a sample of 705 consumers who were given a questionnaire to collect information about their economic status and their attitudes toward milk and special milk consumption. Findings The results were analyzed in order to identify the socio-economic and behavioral characteristics of homogeneous groups of consumers. They consume milk mainly because it is not expensive and it is possible to easily buy it in the supermarket. They consume special milk mainly because of food allergies or intolerances. They would like to buy special milk at large-scale retail trade outlets; they underline difficulties in finding and purchasing it. They think that the price of special milk is very high. Originality/value The results showed that those who occasionally consume special milk choose it because it is more nourishing or for health reasons; there is also a significant association between the judgment on prices of special milk and the frequency of purchase. The estimation of a generalized linear model allowed to highlight that only age and the presence of health problems/intolerances are significant predictors of special milk consumption.

Environmental Strategy in Business: Green Marketing Communication

Purpose: The aim of the paper is to explore the issues of green marketing and green marketing communication. Design/methodology/approach: The narrative literature review is a method applied to achieve the aim of the paper. Findings: The growth of environmental sensitivity is a driving force for change towards new policy tools and environmental eco-nomics. Businesses have developed various tools for environmen-tal communication including environmental balance sheets, social reports, and certifications. It is not enough for businesses to com-municate generic commitment to environmental protection; they have to integrate the concept of ecology into corporate culture by creating strong environmental policies and environmental ethics that describe the enterprise at all organisational levels. Businesses focusing on the development of green products must not only ‘talk ecologically’ but also ‘be ecological’. Research and practical limitations/implications: The research has an exploratory character since the sample strategy is not probabilistic. Originality/value: The study can stimulate discussion in the field of green marketing and green marketing communication. Paper type: literature review.

Economic analysis and energy valorisation of by-products of the wine supply chain: the case of the ‘Mamertino wine PDO’

Abstract The paper reports the analysis of biomass derived from maintenance of a vineyard, to assess its potential as an alternative energy source, instead of the usual disposal of the wine supply chain’s residuals. The site studied is within the province of Messina, Sicily, in the area of Mamertino wine PDO, a wine of superior quality. The analysis suggests that use of this kind of biomass may allow a fossil fuel such as liquefied petroleum gas (LPG) to be replaced by a wine wood chip biomass boiler, thus meeting economic and environmental criteria by reason of recycling for sustainability.

A feasibility study for a project of alternative energy production in an agritourism business in Sicily

Abstract The exhaustion of fossil fuels compromises sustainable development. This paper reports a study of the feasibility of an agritourism business aiming at producing renewable photovoltaic and piezoelectric energy. It evaluates the positive environmental impact of strategies to promote restructuring projects of rural businesses. The research examines not only the economic benefit for the farm, arising from the use of piezoelectric energy, but also the socio-economic benefit (positive externalities) occuring with the reduction of CO2 emissions.
