“…Sicily and other southern Italian regions are well behind the rest of the country in terms of anaerobic digestion plants and the agro-energy chain in general [45]. The production potential of bio-methane in many parts of southern Italy is undeveloped and even unknown despite being potentially very high [46].…”

Due to the necessity of developing renewable energy sources, the anaerobic digestion for producing biomethane has developed significantly in the last years, since it allows to both reduce disposal treatment and produce green energy. In this field, fruit and vegetable wastes have been recently put forward, since they could represent a suitable resource for producing biomethane as a new frontier within the context of a circular economy. This study aims at filling the gap in the knowledge of the production, quantities and biogas potential production of these residues. On this basis, a GIS-based model was developed and applied to the Sicily region by investigating the specific regulatory framework as well as by analysing descriptive statistics. The results of the GIS analyses enabled the localisation of the highest productive territorial areas and highlighted where fruit and vegetable wastes are abundantly located. In this regard, about 7 million Nm3 of biogas could be produced by reusing only the fruit and vegetable residues coming from the three most representative Sicilian wholesale markets among those considered. Finally, the regulatory framework is of crucial importance in inhibiting or supporting the use of the selected biomass in a specific sector, with regard to the case study considered.

“…Etna area (Italy). A sample of 140 students participated in a non-hypothetical experimental auction which is a well-established method of assessing the WTP for food products (Lusk and Shogren, 2007;Pappalardo and Lusk, 2016;Wongprawmas et al 2016;Pappalardo et al 2017;Pappalardo et al, 2018;Selvaggi et al, 2018a and 20181b). This type of experiment offers the advantage of providing an incentive for participants to truly reveal their preferences.…”

In the wine sector, experiential marketing is becoming increasingly important since the success of a wine hinges on “experiential” attributes that include hedonic and symbolic values associated with emotions. An aspect not yet fully explored in the scientific literature concerns the extent to which emotions aroused by the environment where wine is consumed are able to influence consumers’ evaluation of wine. To this end, we conducted an economic experiment in Italy in the territory of Mt Etna, Sicily and through a non-hypothetical experimental auction we assessed the effects of 10 emotions related to the environment of Mt Etna on consumers’ Willingness to Pay (WTP) for Etna wine. The results of this study show that the values of consumers’ WTP for wine are affected by emotions aroused by the experiential environment of Mt Etna.

“…Existing studies on the demand for fertilizer products derived from dairy manure are all based on responses from European producers; we know of no peer-reviewed study in US agriculture 1 . In a study conducted in Sicily, Pappalardo et al (2018) found that farmers' willingness-to-pay for digestate (a product of anaerobic digestion) was strongly influenced by how much information they had about the digestate. Pampuro et al (2018) conducted a survey and focus groups to determine farmers' attitudes toward using pelletized composted manure in Northwestern Italy and found that nitrogen content was the most important attribute to farmers.…”

The use of bio-based fertilizers derived from dairy manure can provide a valuable source of fertility, improve soil health and provide an outlet for manure from dairy operations. We conducted a small-scale discrete choice survey of crop farmers and crop consultants in Washington State to determine the attributes that were important to them in the potential use of a bio-based fertilizer product derived from dairy manure. Of the attributes examined, distribution channel was not statistically significant. Respondents preferred air-dried or pelletized forms to wet forms, though there was no statistically significant difference between air-dried and pelletized forms. As expected, uptake increased as price decreased. Our results imply that respondents would be willing to pay 23 and 39% more for an air-dried or pelletized product, respectively, than for a ‘semi-wet’ product. Our results indicate that there are other important attributes beyond the ones in the survey that led respondents to stay with their current fertilizer regime. Qualitative responses in the survey pointed to the need for field trial results and data on nitrogen release from the bio-based fertilizer. Greater understanding of willingness-to-pay and attributes important to potential end users is important for the development of markets for bio-based fertilizers.
