On the way to ‘zero waste’ management: Recovery potential of elements, including rare earth elements, from fine fraction of waste
2018
Abstract Existing schemes of solid waste handling have been improved implementing advanced systems for recovery and reuse of various materials. Nowadays, the ‘zero waste’ concept is becoming more topical through the reduction of disposed waste. Recovery of metals, nutrients and other materials that can be returned to the material cycles still remain as a challenge for future. Landfill mining (LFM) is one of the approaches that can deal with former dumpsites, and derived materials may become important for circular economy within the concept ‘beyond the zero waste’. Perspectives of material recovery can include recycling of critical industrial metals, including rare earth elements (REEs). The…
Influence of carbon to nitrogen ratio on nitrous oxide emission in an Integrated Fixed Film Activated Sludge Membrane BioReactor plant
2018
Abstract In this study a University of Cape Town (UCT) Integrated Fixed Film Activated Sludge (IFAS) Membrane BioReactor (MBR) wastewater treatment plant was monitored in terms of nitrous oxide (N2O) emissions. The short term effect on the N2O emission due to the influent carbon-to-nitrogen (C/N) ratio variation (C/N ratios of 2, 5 and 10 gCOD/gN) was evaluated. Since in a previous study, the effect of the C/N ratio was studied in the same system without biofilm (UCT-MBR configuration) the main aim here was to investigate the role of biofilms on N2O emissions. Under all the investigated C/N ratios, the N2O fluxes and the average emission factors were lower than that of previous studies with…
EVALUATION OF THE COMBINED EFFECT OF VEGETATION AND NATURAL VENTILATION IN NEARLY ZERO ENERGY MULTI-STOREY BUILDINGS – nZE(ms)B
2020
Cooling load is the main cause of high energy consumption for tall buildings in tropical climates while the construction of tall buildings is an unavoidable practice due to land scarcity in metropolitan cities. In this regard, the use of natural ventilation (NV) in tall buildings can help reducing the energy consumption. However, this solution can also bring the problem of polluted air that may enter the space to be ventilated. If the air is passed through a system that can absorb pollutants and add more oxygen to the air, the problem may almost be solved. Building integrated vegetation (BIV) systems can help solving this problem. So, if the air entering buildings passes through dense veget…
Articular la nación. La María de Ayguals de Izco y la nacionalización española (1845-1850)
2017
Los estudios más recientes sobre el nacionalismo subrayan el carácter narrativo de las identidades nacionales y la necesidad de cuestionar los modelos teóricos elitistas de construcción nacional. En el texto parto de estas propuestas y del concepto de "articulación" de Michael Kennedy y Ronald Suny para estudiar la interacción que se produce María, la hija de un jornalero (1845-1846) de Wenceslao Ayguals de Izco. Estudio la nacionalización que lleva a cabo Ayguals de determinados lenguajes (honor, amor, religión) que eran fácilmente reconocibles por sus lectores. Posteriormente analizo las estrategias narrativas que utiliza y que pudieron contribuir a que la novela fuera leída nacionalmente…
TAKING INSPIRATION FROM NATURE: RULES AND PROCEDURES FOR A GOOD BUILDING PRACTICE
2016
Sin dai tempi antichi si sono sfruttati gli alberi ed altri elementi vegetali per scopi costruttivi: la natura, in generale, è stata di ispirazione e ha insegnato una serie di regole, a lungo imitate ed applicate. Alcune delle numerose specie arboree hanno rappresentato, infatti, degli esempi per le costruzioni primitive e, successivamente, per gli stili architettonici classici: possiamo annoverare i primi rifugi estemporanei ed ispirati a criteri di urgenza e praticità, o anche ben più ragionati edifici, fatti di elementi vegetali assemblati fra di loro. Questi manufatti architettonici richiamavano la natura nel suo fiorente sviluppo e nel sapiente e preciso equilibrio. L’architettura clas…
Çështja e gjuhës greke gjatë gjysmës së dytë të shekullit XVIII dhe kontributi i Tommaso Stanislao Velastit për lëvizjen e filohelenizmit napolitan
2022
Il saggio ricostruisce l'attività intellettuale di T. S. Velasti e illumina il suo contributo alla definizione della questione della lingua greca alla luce della documentazione inedita conservata presso l'Archivio del Seminario Greco Albanese di Palermo, dove trovò riparo dopo la soppressione della Compagnia di Gesù in Sicilia nel 1767. The essay reconstructs the intellectual activity of T. S. Velasti and illuminates his contribution to the definition of the question of the Greek language in the light of the unpublished documentation preserved in the Archives of the Greek Albanian Seminary in Palermo, where he found shelter after the suppression of the Society of Jesus in Sicily in 1767.
Leading agritourism facilities along Nearly Zero Energy paths: Proposal of an easy-to-use evaluation method
2020
The tourist sector, despite the present severe constraints imposed by the sanitary emergence, can be considered as an important component of almost all countries' economies. In Italy agriturism, in particular, has been experiences a continuously rising trend in recent years. Clearly, such great interest towards these businesses also calls for a deep attention by an energy point of view, in sight of an energy efficiency improvement, hence a lowering of the pressure that such facilities exert to the natural environment. On the other hand, the European Union has been engaged, for a long time, in awarding the tourist accommodations environmental excellence brands, like the EU Ecolabel. Unfortun…
REACHING NET ZERO ENERGY: OVERCOMING CLIMATE CHALLENGES WITH A ‘SOLUTION SETS’ DESIGN APPROACH
2013
The paper proposes an innovative energy performances evaluation and design approach, developed during the II° Ph.D. IEA Task 40 Summer School. The aim of the work is to check the importance of a ‘design with climate’ approach in understanding how much climate conditions can influence the design choices. The idea is to focus on the technical and architectural solutions that have the highest impact on the overall energy performances of the building in its original climate, then to move it to a completely different location, re-evaluating the energy performances of the building, in connection to the new site challenges. The last step is a re-design study in order to achieve the best performanc…
Net Zeb case studies. Leaf House
2015
In this book, accomplished international experts present advanced modeling techniques as well as in-depth case studies meant to lead designers towards the optimal use of simulation tools for the design of net-zero energy buildings (Net ZEBs). The book discusses different design processes and tools used in designing Net ZEBs, starting from the fundamental concepts, design strategies, and technologies. These processes and tools are then evaluated by referring to four diverse Net ZEBs where the authors were intimately involved from the design concept to operation. The high resolution measured performance data from these case studies are compared with the predictions made using the respective d…
Moisture absorption, thermal conductivity and noise mitigation of clay based plasters: The influence of mineralogical and textural characteristics
2016
Abstract Three pre-mixed clay based plasters successfully employed in green building practices in several European countries (Spain, France, Germany, and United Kingdom), mainly used for interior wall coating and finishing, were tested in this paper. Their compositional and textural characteristics as well as plastic behaviour were investigated through a multi-analytical approach in a previous paper. A natural earth (Terra Rossa red soil sampled in north-western Sicily), theoretically appropriate for the production of earthen plaster, was also subjected to the same analytical routine and compared with the three commercially available products. Humidity control capacity by the determination …
