Recycling Expo-2017 International Conference Keynote Speaker Roberto CAVALLO photo
Biography:

He graduated from the Faculty of Agriculture of the ' University of Turin in 1994. In 1996 he founded, together with other shareholders, the cooperative ERICA Soc. Coop. one of the first companies in Italy to deal with waste, both in terms of technical design and communication. By ERICA Soc. Coop. holds up to 1999 as a director only to become, in that same year, President and finally, in 2014, CEO. From 1997 to 1999 he was Minister for the Environment, Agriculture and Civil Protection of the City of Alba. In 2001 he was appointed an expert evaluator for the European Commission Directorate General Research. Since December 2002, he was appointed President of AICA (International Association for Environmental Communication). In June 2003 he joined the Board of Directors of ACR + (Association Cities and Regions for Recycling and Sustainable Management of Resources) of which he was elected vice president in November 2014. In that same year the Ministry of the Environment and the Sea appointment horse vice president of the Scientific Committee for the implementation and development of the National Plan for the Prevention of Waste in office until 2017 (Ministry of Environment, Land and Sea, the Ministry decree Gian Luca Galletti, n. 185 dell ' July 8, 2014)

Abstract:

Waste prevention, prepare for reuse and recycling are the three steps of European hierarchy of sustainable management of waste following European Directive 98/2008. Numerous local initiative demonstrate that the best performing results are obtains when different level of responsibility working together. The common interest is reduce the final disposal of unsorted urban waste, increasing quota of valuable waste and this is possible when the economical and financial streams are transparent and there is a direct influence of behaviour on tax. Different kinds of instruments are been developed during last year in order to calculate the quantity of urban (domestic and commercial) waste produced by the citizens. Best results are obtained through volume measure, using both bins and flexible bags. In village ore scattered area bags with bar code or other system of direct recognition could be best option in cost/benefit; in urban area, with important density population and commercial waste, RFID technology it seems to be best. The most frequent experiences in Italy and Europe are based on the volume of unsorted waste following the principle that more citizens use public services of collection more then pay, recent experience are computing also biowaste and packaging collection. PAYT schemes improve selective collection efficiency (i.e. low frequency, correct volume) reaching high percentage of selective collection, above 80%, with an excellent quality of materials collected (impurity less than 5%). PAYT introduce a high level of consciousness of citizens who change the buying behaviour, choosing product with less packaging, reusable, easy to separate, at the same time the shop improve their ecological offer. So PAY scheme is the best opportunity to create a relationship of mutual responsibility between the different actors of the municipal waste management.

Biography:

Sébastien Déon obtained his PhD degree from the University of South Brittany in 2007 on the modeling of transport through nanofiltration membranes. In 2008, he became Assistant Professor at the University of Franche-Comté where he has broadened his areas of expertise to electrokinetic characterizations of membrane materials and fouling cakes. Currently, he is Associate Professor and his skills are mainly dedicated to water treatment by membrane processes. He is also the author or coauthor of one book, twenty six publications in international recognized journals, and some twenty presentations in international conferences. His expertise in reviewing scientific papers led him to become Associate Editor of International Journal of Membrane Science & Technology, Academic Editor of International Journal of Chemical Engineering and an Editorial Board Member of four other peer-reviewed journals.

Abstract:

Nanofiltration can find applications in several environmental or industrial fields since its size and electrical properties make it perfectly suitable to remove small charged pollutants such as metal ions from contaminated effluents. In this context, a predictive tool could be a very useful for process development or optimization. Several approaches are available in literature but the coupling between equilibrium partitioning at the interfaces and the extended Nernst-Planck equation to describe transport within the pores is probably the most convenient approach to model multi-ionic separation. The major limitation for such a predictive model lies in the estimation of physical parameters. In this presentation, several ways developed to determine the input parameters are discussed to check if a fully predictive model is potentially achievable or if it remains a fanciful dream. The presentation will be mainly devoted to estimation of the membrane charge density (Xd) and the dielectric constant of the solution within pores (p), which are the two key parameters of the above-mentioned approach. Firstly, the outstanding predictions of filtration performances obtained with an original numerical procedure based on the simultaneous fitting of multi-component rejection curves will be highlighted. Then, various experimental methods developed recently to determine these physical parameters, such as streaming or membrane potential measurements or electrochemical impedance spectroscopy, will be also presented before discussing their respective advantages and drawbacks for predictive purposes.
