Improved Sustainability in Wine Industry Byproducts: A Scale-up and Economical Feasibility Study for High-Value Compounds Extraction Using Modified SC-CO2

[Image: see text] The objective of the present work was to optimize the operating conditions (P, T cosolvent %) and to study the scale-up and the feasibility of the supercritical fluid extraction (SFE) process for polyphenols from grape pomace, the main solid byproduct of the wine industry. Pilot-scale equipment (1 L extraction vessel) was used to study the scale-up prediction for extraction vessels of 50, 100, 500, and 1000 L capacity. The adopted scale-up criteria consisted of maintaining and keeping constant the solvent mass-to-feed mass ratio and the bed geometry dimension. The results indicated an excellent predictive level obtained by Sovová’s model and success of the adopted scale-up criteria. At industrial scale, yields were close to 2.3 g(GAE)/100 g(DM), a value obtained using the pilot-scale equipment. High concentrations of high-added-value phenols such as cis-resveratrol glucoside, cis-coutaric acid, trans-p-coumaric acid, quercetin, and proanthocyanidins were found in the extract. An economic evaluation of the process indicated the feasibility of an industrial SFE plant with a capacity of 500 L for producing in 60 min an extract with an expected phenolics’ concentration of approximately 133 g(GAE)/kg (extract) at an estimated 67€ /kg(extract) cost of manufacturing. Notably, all values are better than those currently reported in the literature

Science diplomacy and trans-boundary water management. The Orontes River case

The Mediterranean Basin in general, and more specifically its southeastern part, is encountering rapid changes leading to huge water stress and the tiniest percentage of available drinking water per inhabitant in the world. Changes leading to water scarcity include growing population, with rates annually exceeding 2.8%, and excessive water demand for irrigation. Climate change exacerbates water droughts and risks. Overall national sovereignty, political, social and economic factors seem to be equally important to the scarcity of water resources, which may influence conflicts and violent clashes (\u201cwater riots\u201d).This is the reason why water and hydro-diplomacy occupy a central space on the diplomatic agenda of the governments in the region, including Lebanon, Syria, Jordan, Palestine, Israel, Egypt and Turkey. To guarantee the equitable use of water resources for the population of the countries involved, a major task of hydro-diplomacy is to overcome a number of challenges and critical thresholds by exploring all possible options for consensus building and by using reliable scientific evidence.Hydro-diplomacy, as applied in the case of the Orontes, builds partly on traditional bilateral approaches, taking account of power relations, partly on observing International Law and partly on pursuing new methods and tendencies based on the analyses of the actual water needs at national and local level, considering in particular the most vulnerable communities and enhancing prospects for social and economic development.The present publication is based, on one hand, on the results of the ICT project funded by the Italian Development Cooperation (Ministry of Foreign Affairs and International Cooperation) through the University of Insubria, and on the other hand, on the data and accumulated experience of hydro-diplomacy efforts. It thus brings together two approaches: first a crisp analysis of the evolution in addressing the water challenges applying technological tools on basin management, and secondly, a pragmatic one, based on a case study dealing with water resources in the Middle East

Impact of Global Change on the Socio-economic Development of Venice

Il convegno era destinato a fare da premessa a una nuova edizione del Rapporto UNESCO su Venezia a 50 anni dalla pubblicazione del primo storico contributo. Gli estensori del Rapporto hanno operato come rappresentanti dei due enti di ricerca coinvolti: Bruno Bernardi come presidente del COSES e Mario Scalet come head of scientific unit dell'UNESCO Venice Offic
