Smart biogas grid: biogas utilization to operate diffused micro-generation solutions in urban areas through the bio-waste exploitation
No full textThe importance of renewable energy exploitation has been a main topic in the European Union since the 2001/77/CE Directive publication, further reaffirmed with Directive 2009/28/CE. The critical point is represented by the existing stock and urban areas, especially connected to residential districts. The challenge is to implement energy production to have autonomous districts and low-carbon producers. Micro-generation systems offer the possibility to produce locally the
whole or a part of the energy needed by the districts, and among the renewable energy sources (RESs), biogas is getting its space. Bio-waste, green waste, all organic materials can be resources to produce biogas as energy recovery. From the regulatory framework to the economic program of the district and residents’ behaviour, from State or local policies for developing biogas in RESs’ scenario to the definition of the limits of biogas production and its integration in existing districts and with other systems of sustainable energy production, the PhD thesis tries to be an example of multidisciplinary approach in scientific research. Indeed, its aim compels to compare many disciplines from environmental, social and economic, in the topic of sustainability. Many are the aspects to take into consideration: citizens’ behaviour, waste practices and management, technologies applicable at building and at district scale, innovative solutions for regulatory framework and business plan, all these components contribute in the success or the failure of biogas energy system in urban areas. Through a strict analysis of the topics related to possible biogas application and diffusion in districts, the work identifies new steps to improve European common guidelines able to support biogas development, in order to have a fully available instrument for authorities, enterprises and neighbourhoods. The work wants to be a contribution for Smart Biogas Grid realization so as to create energy independent urban districts, where the householders could become virtuous producers of their energy through an efficient zero-kilometre waste chain. Biogas offers the possibility to create microgeneration urban centres in line with energy European programs, a new economic and social model for energy able to fully increase RES sensitivity in communities and to develop energy efficiency practices

L’Energia ‘per’ il Cittadino: accezioni, utilità e potenziale produttivo. Dalla percezione d’utenza delle Fonti Energetiche Rinnovabili alla definizione di nuove strategie a livello di quartiere mediate dal ruolo pro-attivo dei cittadini.
No full textLo sviluppo delle energie rinnovabili è uno dei topics che negli ultimi 20 anni ha acquisito sempre maggior rilevanza nelle politiche nazionali e europee. Uno studio delle relazioni tra quartieri, abitanti e le loro abitudini energetiche pare
uno strumento efficace per la valutazione e la promozione di programmi innovativi per l’approvvigionamento energetico basati su nuovi modelli di sviluppo e di partecipazione dell’utenza.Since the White Paper in 1997, Renewable Energy Sources (RESs) are considered as alternative solutions to promote a new approach on energy topic with the aim to challenge the dependence on traditional fuels, reduce Greenhouse Gas (GHG) emissions, diversifying energy supply. Nowadays, if the results achieved can be considered positive as part of an increasing trend, it is crucial for further developments and the success of future policy frameworks identifying which is citizenship’s perception and awareness on energy topic. Population cannot be only passive final users of RES, but has to become active protagonist in the whole process. After two decades of policies and technologies application, RESs can move into tools able to innovate sustainable practices, educating citizens on their role in energy needs inside their districts; are citizens ready for this challenge

La gestione del rifiuto organico urbano attraverso l’utilizzo di microdigestori anaerobici: il caso studio di Camley Street Park, Londra, UK
No full textIl caso studio del micro-digestore anaerobico di Camley Street Park, Londra (UK) converte gli scarti del cibo del quartiere in biogas, dimostrando il potenziale energetico del rifiuto organico e riducendo l’impatto ecologico della gestione dei rifiuti.The urban waste management is a crucial issue because of the increase of urban population in the next years; for this reason new solutions for the waste management and the reduction of the carbon footprint need to be investigated. The paper presents the case study of a micro-scale anaerobic digester located in the urban environment of Camley Street Park in London, UK. The plant, built in 2013, processes urban food waste – household and catering waste – generating biogas used for the local community café. Through the involvement of local district population to provide food waste under fee charge, the plant produces biogas with an average amount of 60,6%. The results achieved by the Camley Street park’s plant underline the sustainability of micro-scale anaerobic digesters within urban environment in reducing the emissions of CO2eq from the utilization of biogas – renewable energy source that replaces current fossil fuel utilization – and from food waste diversion from landfill disposal

No full textThe educational space and its design represent a first step towards the promotion of inclusive strategies, especially if it hosts activities for students with dyslexia. Indeed the need for social integration and individual works of people with learning difficulties can be better applied in a room designed with precise rules. The set of furniture and the ICT, the digital instruments for dyslexia compensation, have to be integrated with the psychological tools able to improve the students’ self-confidence and the implementation of their capabilities; with this aim the application of proxemic regulations helps to identify the proper distance among students, their colleagues and teachers. The result is a space for students both with dyslexia and not, which allows to work individually, pledging the personal work, optimizing the relations among users and developing a new self assurance, a space which strengthens the existing immaterial technologies and strategies
Organic waste management through anaerobic digester technologies in urban areas. A multicriterial predesign tool to support urban strategies
No full textThe daily production of waste within urban areas represents an opportunity to transform its organic fraction in biogas through anaerobic digestion, but until now it has not been studied and considered as an applicable urban solution. This paper presents a part of the results achieved in the research named “Smart Biogas Grid”, study conducted with the aim to investigate the perspective for the realization of small-scale anaerobic digesters to produce biogas exploiting bio-waste produced in urban areas. While the scientific technical literature on biogas is deeply investigated, experiences and literature for urban context are poor with only few cases and prototypes. Starting with the presentation of a case pilot of anaerobic digester realized in Camley Street Park in London, UK, the paper goes beyond the only technical and technological aspects, considering the role of non-technical features of anaerobic digester installation and providing a transversal analysis to focus on the architectural and urban planning consequences. It emerges the need for a multi and inter-disciplinary approach that can find in the support of early design tool and useful instrument to help in organizing and managing the contents proper of different disciplines; the tool presented in the paper has this purpose. Through a multi-criteria decision analysis, statistical data, features of the urban areas object of intervention, the tool defines a set of solutions, which can contribute in the activation of strategies of waste prevention, energy utilization and community awareness thanks to people/stakeholders engagement at different scales. The result is a decision-making tool useful to direct pathways for socio-technical from a district to the city scale, supporting the definition of urban local strategy to the creation of anaerobic digesters in urban areas, in existing as well as in new settlements
La micro-cogenerazione a biogas: se partecipare vuol dire risparmiare [con consapevolezza]. Prospettive di sviluppo in ambito urbano: analisi sintetica delle attuali criticità (normative e procedurali) a livello nazionale e individuazione di alcune strategie di facilitazione per l’adozione di impianti a biogas.
No full textDalle direttive europee alla ricezione nazionale, il biogas urbano si confronta con un complesso scenario normativo e con un mutevole sistema di incentivi. Dal confronto con le esperienze europee, nuove strategie per lo sviluppo della micro-generazione urbana da biogas possono essere adottate. I European Strategy towards 2020 energy targets aims to develop renewable energy sources in order to guarantee the promotion of new sustainable practices and reduction of green house gas emissions; biogas is a source which can allow to achieve this goals in line with Energy Directive 2009/28/CE and Waste Directive 2008/98/CE. Although the biogas international scientific research and worldwide sustainable experiences are in progress, a huge limit in urban biogas set up is represented by national regulatory framework and financial programs issued. Despite the fact that Italy is the third worldwide producer, biogas suppliers have to challenge with a complex regulatory
framework and with uncertain policies. Policies, authorization processes, incentives uncertainty, public-private conflicts can not be an obstacle for biogas micro-generation diffusion. The Italian regulatory framework analysis and its comparison with EU practices and frameworks could allow to identify new available solutions and guidelines for biogas diffusion and development
