Assessment of landfill leachate biodegradability and treatability by means of allochthonous and autochthonous biomasses
2020
Abstract The biodegradability and treatability of a young (3 years old) municipal landfill leachate was evaluated by means of chemical oxygen demand (COD) fractionation tests, based on respirometric techniques. The tests were performed using two different biomasses: one cultivated from the raw leachate (autochthonous biomass) and the other collected from a conventional municipal wastewater treatment plant after its acclimation to leachate (allochthonous biomass). The long term performances of the two biomasses were also studied. The results demonstrated that the amount of biodegradable COD in the leachate was strictly dependent on the biomass that was used to perform the fractionation tests…

Innesto di catene polimeriche sulla superficie di nanotube di carbonio mediante reazione di accoppiamento radicalico
2015
La modifica di nanotubi di carbonio (CNT) attraverso innesto (grafting) di catene polimeriche sulla loro superficie è un metodo efficace per promuovere la dispersione di queste cariche a livello nanometrico in una matrice polimerica. La funzionalizzazione covalente di CNT con catene polimeriche viene generalmente ottenuta sia attraverso crescita controllata di polimeri a partire dalle pareti della nanocarica mediante metodi "grafting from" sia attraverso metodi di "grafting to" che si basano sulla reazione di condensazione tra polimeri preformati e CNT opportunamente modificati. In questo lavoro viene proposto un nuovo approccio di tipo "grafting to" per innestare catene polimeriche su CNT …

BIODEGRADAZIONE DEGLI IDROCARBURI: DALLE COMUNITÀ MICROBICHE MARINE AI SISTEMI READY TO USE PER IL BIORISANAMENTO
Crude oil is one of the major hazardous pollutants. A promising technology for the treatment of contaminated sites is based on biodegradation of oil pollutants by microbial populations. Several microorganisms are known to use hydrocarbons as carbon sources. In the marine environment, obligate hydrocarbonoclastic bacteria (BIC) have been defined as being ecologically important for the aerobic removal of hydrocarbons. Recent advances in microbial ecology make it possible to combine molecular and culture-dependent approaches to identify bacterial community at environmental sites. In this thesis a microbiological survey of the Priolo Bay (eastern coast of Sicily, Ionian Sea), a chronically poll…

Biodegradable polymer-wood flour composites: main properties and biodegradability
2009
During the last years, a considerably increasing rate of attention has arisen on biodegradable polymers. In the meanwhile, the use of wood-plastic composites (WPC) has grown in importance, especially in the United States. The combination of biodegradable polymers and wood-based fillers allows obtaining the typical advantages achievable with the use of WPCs, with the further advantage of the biodegradability and compostability of the matrix (and not only of the filler). In this work, the characterization and the biodegradability assessment of Mater-Bi®-wood flour composites have been carried out.
