A Green Approach for Recycling Compact Discs
2023
Compact discs (CDs) and digital versatile discs (DVDs) are mainly made by polycarbonate disc, a thin layer of aluminum or silver, a thin layer of a coating and a thin layer of a label of paper or PET. The recycling of these discs is difficult due to the removal of these non-polymeric layers and to our best knowledge, no industrial plants have been resent for their recycling. In this work, we propose a facile way to remove the non-polymeric layers and investigate the effect of the repetitive extrusion process on the processability and on the mechanical properties of the recycled polycarbonate. A few works have been published dealing with both the removal of the non-polymeric layers and the m…
Culinary Tourism. A New Trend on the Tourism Market
2017
Seen as a new form of manifestation of the behavior of the consumer of tourism products and services, culinary tourism has recorded an ascending trending the last years, with a positive forecast for the following years. A possible explanation for this phenomenon is the orientation and encouragement of the tourist services providers to adopt regional development strategies that harness traditional local resources and products in a context where the contemporary consumer no longer only pursues the acquisition of products and services to meet their needs, but also looks forward to new experiences that are a delight for the senses. Against this background, the present paper aims to highlight so…
CIRCULAR PROCESSES FOR A NEW URBAN METABOLYSM: THE ROLE OF MUNICIPAL SOLID WASTE IN THE SUSTAINABLE REQUALIFICATION
2014
Through this paper we present the first results of a research combining the management problem of Municipal Solid Waste to the requalification of built environment. The goal of this research is to mitigate the vulnerability of territory and urban heritage and to transform a problem into opportunities. Above all, we have paid attention to several exemplifying cases of Italian territory: suburbs of large towns, historical centres, small centres (and, in particular, those with a strong historical connotation). Their features are, at the same time, restrictions and challenges for designing new compatible systems that can contribute to the requalification of urban landscape recovering spaces wit…
Preliminary Evaluation of Plasmix Compound from Plastics Packaging Waste for Reuse in Bituminous Pavements
2021
Finding an appropriate technical solution for reusing waste plastics is crucial for creating a circular plastic economy. Although mechanical recycling is the best option for recycling post-consumer plastics, some heterogeneous mixed plastics cannot be recycled to produce secondary material due to their very low properties. In this case, alternative routes should be considered in order to limit their disposal as much as possible. Therefore, in order to solve the environmental problems in the landfills of plastic waste recycling, and to improve the mechanical performance of bitumen for road pavement, the reuse of these post-consumer plastic wastes are preliminarily evaluated for the modificat…
Limits to CO2-Neutrality of Burning Wood. (Review)
2016
Abstract Consumption of wood as a source of energy is discussed with respect to efficiency and restraints to ensure sustainability of the environment on the grounds of a simple analytical model describing dynamics of biomass accumulation in forest stands – a particular case of the well-known empirical Richards’ equation. Amounts of wood harvested under conditions of maximum productivity of forest land are presented in units normalised with respect to the maximum of the mean annual increment and used to determine the limits of CO2-neutrality. The ecological “footprint” defined by the area of growing stands necessary to absorb the excess amount of CO2 annually released from burning biomass is…
Territorial Intelligence and Governance.
2007
International audience; As with European experiments, in various regions in France, territorial intelligence projects have been initiated since 2003. (see the regions of Lower Normandy, Lorraine, Réunion Island, the Aquitaine region, etc.).The objective of these is to gather and exploit information which is not confined to particular sectors and the collective processing of which can contribute to durable development. Apart from institutions, civil society and the inhabitants of the territory, it is observed that companies and in particular small and medium sized enterprises are natural partners who show interest in such initiatives. Both the different economic chains and the participating …
Measuring Socio-Economic Welfare and Sustainable Transport – Selected Dilemmas
2017
The aim of this paper is to present and elaborate relations between the understanding and main indicators of socio-economic welfare, including indicators of sustainable development, and the measurement methods of sustainable transport. The focus is on the role that transport basically plays for nearly all dimensions of living conditions and the quality of life. First, the defi nition of socio-economic welfare and different views on measuring welfare are presented. Then, the meaning of transport for improving socio-economic aspects of life, as well as the need for sustainable transport are underlined. In the last part of the article developed indicators of sustainable transport are discussed…
MUV: A Game to Encourage Sustainable Mobility Habits
2019
This working paper investigates the question of changing people mobility towards more sustainable habits involving them in an engaging gameplay. The work is performed within MUV H2020 research and innovation action. The game design, definition and features have been co-created through the involvement of different citizens and stakeholders in six European neighbourhoods. The paper discusses the game design as resulting from co-creation and co-design experiences with each neighbourhood communities involved in initial phases. The paper argues that the local co-design activities have influenced the game definition, together with the community engagement approach. The MUV gameplay approach resul…
The role of water in sustainable architecture
2011
Today’s propulsive push towards the 3th millennium, driven forward by technological innovation, needs to grapple with an economic and environmental global crisis. Generally speaking water is synonymous with life; in bio-climatic architecture it is synonymous with thermal comfort, since water is able to regulate the micro-climate of various interiors, help solar radiation and brighten up internal spaces. There is more, however. In certain cases, water becomes an actual building element: thanks to the considerable power of its thermal mass, it can be used in passive solar systems (with the “drum wall” in place of stone, brick or concrete walls), through the employment of the “trombe” wall, or…
La sostenibilità dei rimedi consumeristici nella Direttiva 771/2019/UE e oltre
2022
Lo sviluppo sostenibile è al centro dell’agenda. Stati, istituzioni internazionali e attori privati sono impegnati nell’Agenda 2030 e nei suoi obiettivi. Uno dei compiti più importanti è l’implementazione di un consumo sostenibile. In questo contributo, si tratterà di verificare come il diritto dei consumatori possa aiutare a raggiungere questo obiettivo.
