Design e ficodindia : per uno sviluppo locale sostenibile
2017
L’articolo descrive il rapporto tra il design e un prodotto dell’agroalimentare siciliano, il ficodindia di Roccapalumba, per uno sviluppo economico e territoriale nel rispetto dell’ambiente. A tal fine il ficodindia è considerato risorsa in grado di avviare delle innovazioni, come la valorizzazione degli scarti e la relazione tra gli attori locali. Nell’articolo, per generare una seconda vita agli scarti, si è studiato il ciclo di vita del ficodindia e tra i vari output si è considerato la potatura dei cladodi da cui si è ricavato una fibra, utilizzata in modo innovativo e secondo una visione locale, puntando sul patrimonio culturale e sulle tradizioni. The article describes the relationsh…
Design and Agrifood for new sustainable local development
2019
This paper is about the relationship between design and the prickly pear of Roccapalumba (Sicily), a product of the agrifood chain, considering it as a resource able to start innovative strategies for waste recycling and for a sustainable local economy. The study examines the entire life cycle of prickly pear and, among the various outputs, considers the cladodes to obtain cellulosic fibres, mucilage for cosmetics and for restoration of cultural heritage, the flowers for infusions and the fruit seeds for an oil with nutraceutical properties to generate a second life of the prickly pear. This will lead to economic and environmental benefits in the territory, creating a network of companies w…
Silver based sensors from CD for chloride ions detection
2021
This preliminary work shows a new and innovative way to produce silver based electrodes from compact discs and its application towards the detection of chloride ions. A complete sensor was obtained from the compact discs with working, reference and counter electrode made of silver. Chloride ions were detected by exploiting the high affinity of silver with this anion to produce silver chloride. This electrochemical oxidation of silver can be monitored by using an electrochemical technique such as linear scan voltammetry. Indeed, during linear scan voltammetry the oxidation of silver to silver chloride lead to a peak current that increases linearly with chloride concentration. Using this tech…
Co-Evolutionary Coupling via a Digital-bio Ecosystem – A Suggestion for a New R&D Model in the Digital Economy
2019
A solution to the critical problem of a dilemma between R&D expansion and productivity decline that a majority of information and communication technology (ICT) leaders have been confronting in the digital economy is expected. It can be expected by a spinoff from economic functionality-seeking GDP-based coevolution cycle to supra-functionality beyond an economic value-seeking uncaptured GDP-driven coevolution cycle. However, the transformation dynamism remains a black box. By means of numerical simulations based on empirical analyses of the development trajectories of global ICT leaders, focusing on Amazon and Finland, together with an intensive review of preceding analyses, this paper atte…

Life cycle assessment of a new industrial process for sustainable construction materials
2023
One of the key sectors for the green transition of European countries is construction, that is more and more asked to evolve towards innovative ecological binders and green cost-effective processes. The construction sector is highly energy intensive, and the cement production is one of the main sources of environmental pollution in the world. In this regard, GeoPolymers (GP) seem to be promising for a sustainable replacement of cementitious materials. Therefore, the Life Cycle Assessment (LCA) of the industrial production of different formulations of Geopolymer Concrete (GC) was performed in this study after scaling up the Life Cycle Inventory (LCI) from a laboratory scale to an industrial …
Paradigms on landfill mining: From dump site scavenging to ecosystem services revitalization
2017
For the next century to come, one of the biggest challenges is to provide the mankind with relevant and sufficient resources. Recovery of secondary resources plays a significant role. Industrial processes developed to regain minerals for commodity production in a circular economy become ever more important in the European Union and worldwide. Landfill mining (LFM) constitutes an important technological toolset of processes that regain resources and redistribute them with an accompanying reduction of hazardous influence of environmental contamination and other threats for human health hidden in former dump sites and landfills. This review paper is devoted to LFM problems, historical developm…
Energy recovery from Municipal Solid Waste in EU: proposals to assess the management performance under a circular economy perspective
2017
In 2015 the European Commission issued a package of documents on Circular Economy concerning an integrated revision of legislative proposals on waste management. The aim was to stimulate a European transition towards a circular economy concept, which is expected to foster competitiveness, sustainable economic growth and new jobs generation. Three indicators are proposed in this paper to contribute to the assessment of the energy recovery management performance from MSW in a scenario of circular economy: a) referring to MSW directly used (RMSW) or indirectly used (SRF) as input of thermochemical plants, an indicator can be the percentage of waste having LHV > 13MJ/kg; b) referring to the MSW…
Anaerobic membrane bioreactors for resource recovery from municipal wastewater: a comprehensive review of recent advances
2021
[EN] In a paradigm shift towards a sustainable society based on the Circular Economy, wastewater treatments are rapidly evolving towards simultaneous recovery and reuse of clean water, renewable energy, and nutrients. This review examines recent advances (from 2016 to 2020) in the potential of anaerobic membrane bioreactors (AnMBRs) to serve as the core technology for municipal wastewater (MWW) resource recovery, focusing on the latest technological advances and economic and environmental innovation perspectives. The potentials and limitations of AnMBR for further full-scale application and new platforms to address these challenges are discussed, covering systems based on co-digestion, pre-…
