environmental modelling of aluminium recycling a life cycle assessment tool for sustainable metal management
Journal of Cleaner Production, 2015Co-Authors: Dimos Paraskevas, Karel Kellens, Wim Dewulf, Joost DuflouAbstract:The uncontrolled mixing of metals and their alloys during the different life cycle phases, combined with the melt purification constraints during remelting, pose great challenges during their end-of-life (EoL) treatment. In practice, open-loop recycling is typical and more common for metals than closed-loop recycling; especially in the case of aluminium, the industry operates in a cascade recycling approach. Associated with open-loop recycling are various types of Material losses; loss of original functional quality, dissipation of scarce resources and the final need for dilution of the resulting metal impurities with primary Materials. Thus, an environmental assessment tool is presented within this paper, aiming to support decision making related to the sustainable management of metal resources during secondary aluminium production. A Material blending model aims at the minimization of the above mentioned losses in order to meet the product quality requirements. The goal of the study is threefold: i) to assess the environmental impact calculation of aluminium recycling, ii) to express, quantify and integrate dilution and quality losses into Life Cycle Assessment (LCA) studies, and iii) to determine the optimum Material Input for the recycling process from an environmental perspective. Different recycling options or strategies can be evaluated and compared based on avoided environmental impact. Case studies focusing on major post-consumer scrap streams are used to illustrate application areas and highlight the importance of altering and optimizing the Raw Material Input. Finally, policy issues and opportunities for environmentally conscious metal management are discussed.

successful small scale manufacturing from small islands comparing firms benefiting from locally available Raw Material Input
Social Science Research Network, 2005Co-Authors: Godfrey BaldacchinoAbstract:This paper dRaws on an European Commission-supportedLeonardo da Vinci Vocational Training pilot project-in-progress to review theprospects for SMEs in small island territories. It focuses on manufacturingfirms, and deliberately selects those which conform to a tough set ofconditions of "success": strong and consistent export orientation;local ownership; locally developed or adapted technology; and a workforce of upto 50 employees. This paper is based on "best practice" data collated specificallyfrom five such "successful" firms, each based in one of five Europeanisland regions, manufacturing a product which benefits from locally available,Raw Material Input. Research findings suggest that idiosyncratic features associated withsmallness and islandness identity facilitate business success in such locationsin spite of various well-documented structural handicaps. These featuresinclude a strong branding of the product with the respective island andassociated characteristics island; free riding on island tourism; limiteddomestic local firm rivalry; an appreciation of social capital and the"quality of island life"; and the luring of islanders back to theirisland in order to become local entrepreneurs.(Publication abstract)

SOMMAIRE. Cet article s'inspire d'un projet-pilote de formation professionnelle Leonardo da Vinci, appuye par la Commission Europeenne, pour passer en revue les esperances des petites et moyennes entreprises de petites iles. Avec les manufactures pour point de mire, il choisit celles qui se conforment a de strictes conditions de « reussite » : forte orientation vers l'exportation; possession locale; tech- nologie developpee ou adaptee localement; et jusqu'a 50 employes. Cet article se base sur des donnees « meilleure procedure » recueillies aupres de cinq entreprises florissantes, situees dans des regions insu- laires europeennes et fabriquant un produit jouissant d'un apport local de matieres premieres. Les resultats des recherches suggerent que les traits idiosyncratiques associes a la petitesse et a une identite insulaire facilitent la reussite des affaires, malgre divers handicaps structuraux bien documentes. Ces traits comprennent : forte association du produit avec l'ile concernee et ses caracteristiques; avantages tires du tourisme; rivalite domestique limitee; appreciation du capital social et de la qualite de la « vie sur l'ile »; et attraction vers l'ile des insulaires exiles pour en faire des entrepreneurs locaux.

chemometric applications to assess quality and critical parameters of virgin and extra virgin olive oil a review
Analytica Chimica Acta, 2016Co-Authors: Ana Maria Gomezcaravaca, Ruben M Maggio, Lorenzo CerretaniAbstract:Today virgin and extra-virgin olive oil (VOO and EVOO) are food with a large number of analytical tests planned to ensure its quality and genuineness. Almost all official methods demand high use of reagents and manpower. Because of that, analytical development in this area is continuously evolving. Therefore, this review focuses on analytical methods for EVOO/VOO which use fast and smart approaches based on chemometric techniques in order to reduce time of analysis, reagent consumption, high cost equipment and manpower. Experimental approaches of chemometrics coupled with fast analytical techniques such as UV-Vis spectroscopy, fluorescence, vibrational spectroscopies (NIR, MIR and Raman fluorescence), NMR spectroscopy, and other more complex techniques like chromatography, calorimetry and electrochemical techniques applied to EVOO/VOO production and analysis have been discussed throughout this work. The advantages and dRawbacks of this association have also been highlighted. Chemometrics has been evidenced as a powerful tool for the oil industry. In fact, it has been shown how chemometrics can be implemented all along the different steps of EVOO/VOO production: Raw Material Input control, monitoring during process and quality control of final product.
