Direct Measurement of Methane Emission Rates: Multiyear Application to a Municipal Landfill in Southern Italy
2012
Municipal Solid Waste (MSW) landfills have been identified as one of the most important sources of methane (CH4) emission. MSW contains a certain amount of biodegradable organic matter which undergoes anaerobic degradation resulting in the production of the landfill gas (LFG), which main component is tipically represented by CH4. In order to minimise its negative effects on the envi-ronment, LFG recovery is a suitable tool to control CH4 emissions from a landfill site and the measurement of CH4 emissions represents a good way to evaluate the effectiveness of LFG recover-ing system in reducing biogas emission to the atmosphere. However, up to now few measurements of landfill CH4 emissions ha…
Estimation of methane emission by a municipal landfill: the case of Palermo
2010
CH4 diffuse emissions from municipal solid waste landfills represent one of the most important anthropogenic source of greenhouse-gas. CH4 is produced by anaerobic biodegradation of organic matter in land-filled MSW and it constitutes the major component of landfill gas. Gas recovery is a suitable tool to effectively control CH4 emissions from landfill sites and the quantification of CH4 emissions represents a good tool to evaluate the effectiveness of biogas recovering system in reducing biogas emission. In particular, LFG emissions can be indirectly evaluated from mass balance equations between formation, recovery and oxidation of biogas in the landfill, as well as on a direct approach ba…
PLASTICS RECOVERY FROM MUNICIPAL WASTE: MAINSTREAMS AND BY-PRODUCTS IN A CASE STUDY IN NORTHERN ITALY.
2014
In the case study dealt with here, the factory treatments of dry Municipal Solid Waste are aimed primarily at materials recovery; restraining energy recovery to the hardly recyclable by-products. The main input consists of the so-called multipak from MSW source-sorted collection; plus packaging waste, paper and cardboard and other similar waste from curb-side collection. The principal fractions produced by the selection plant, own and operated by the Public Company in charge of MSW management, in the Year 2012 were 27 064 tonnes of plastics, 5 066 of paper, 3 014 of tin coated steel and 4 886 tonnes of extraneous fraction to dispose of. A minor – though valuable – product was aluminium. The…
Experimental Sorting of Municipal-Like Waste in the Hospital “Civico”, Palermo (IT)
2013
An experiment of source sorting - based management of Health Care Waste (HCW) was carried out in 2011 in 4 Departments of the Public Hospital “Civico” (Palermo, IT), where the basic mandatory separation between hazardous and non-hazardous waste was already going on since year 2000.The experiment consisted in weighing every day for 15 days 4 predefined fractions collected in the Infirmaries (namely paper, plastics, glass and unsorted fraction), and the bags with unsorted waste from the patient’s stay room. Furthermore, in 1 of the 4 Departments also the boxes of Infectious Waste (IW) were weighed for a week.As a result a weighted average value of 0.56 kg of Municipal-like Waste (MLW) per bed…
La Fama dell'Ottangolo palermitano di Giovan Battista Maringo
2011
La sezione Apparati che costituisce la seconda parte del volume dedicato ai Quattro Canti di Palermo propone la selezione di alcune fonti a stampa ritenute utili alla comprensione della storia della fabbrica. Nel 1609 vedeva la luce un prezioso libretto commemorativo, La Fama dell’Ottangolo Palermitano, pubblicato a Palermo, contestualmente all’avvio del cantiere. Al di là della retorica celebrativa e della complessa trama di significati e rimandi di natura allegorica e simbolica, l’importanza dell’opuscolo risiede anche nel fatto esso riveste un interesse “documentario”, dal momento che all’interno contiene una breve ma dettagliata descrizione del monumento all’atto della fondazione, quind…
Hart’s blind spot. The missing piece in The Concept of Law
2014
Al inicio de El Concepto de Derecho, Hart sugiere una asimilación errónea entre conducta que es «no opcional» y conducta que es «obligatoria» (i. e. conducta que o es forzada o sometida a una obligación). Esta asimilación vicia el argumento del libro en su conjunto, llevándole a Hart a descuidar las diferentes vías en las que el derecho monitorea, corrobora o constituye relaciones de poder. Es cierto y evidente que en The Concept of Law la atención se dedica a los poderes normativos, legales. Sin embargo, el poder social bruto, y las relaciones del derecho con él —el papel del derecho como una pieza en la maquinaria de los poderes sociales— están ampliamente ignorados. Éste es, de alguna ma…
Centralità mediterranea della Palermo imperiale e tardoantica (secoli I-IV). Scenari sociopolitici
2020
Through the discussion of sources and analysis of data and material culture, the consideration of social facts with their complex interactions, I want to make a picture of the Roman Panhormus of the imperial age, with its municipal administrators, its senators, its curials, its people; a city that could enjoy theatrical performances, gladiators and venationes thanks to the prosperity manifested by the richness of the mosaics, imbued with that pagan religion, well rooted and still persisting at least until the fourth century.
Understanding short- and long-term implications of “myopic” fleet maintenance policies: a system dynamics application to a city bus company
2010
Financial losses recorded in city bus companies often force managers to implement restructuring strategies aimed at improving business results. However, such decisions may not produce the expected consequences for a number of reasons. Both the internal and external environment in which such companies operate can make the design and implementation of long-term sustainable policies quite difficult. In fact, the result may be that decision makers introduce "effective" policies in a company subsystem, while ignoring the medium- and long-term implications of such decisions in the performance of the whole company. With the aim to detect the main causes underlying "myopic" fleet maintenance polici…
La sfida anarchica nel Rojava
2019
In this book, the editors collect a series of contributions about the revolution in Rojava (Kurdistan), in the name of democratic confederalism inspired by the anarchist ideals of libertarian municipalism by Murray Bookchin
I beni confiscati come nuovo spazio pubblico
2014
Nel territorio a nord-est di Palermo la criminalità organizzata, in molte occasioni, ha condizionato il potere politico e amministrativo e inciso su valori e abitudini collettive, esercitando unʼinfluenza determinante nellʼespansione periurbana e nella conseguente trasformazione del paesaggio agrario. Alcuni dei principali centri oggetto della ricerca hanno governato il territorio sotto il controllo sistematico della mafia rendendo necessario lʼintervento dello Stato. Esaminare i rapporti tra amministrazioni locali e Cosa nostra in quei luoghi permette di individuare ricorrenze criminali nella gestione dei beni collettivi e di concentrare lʼattenzione sulle proprietà confiscate. In the nort…
