International Legal Approaches to Waste Water Discharges. Opening speech
2002
En este discurso inaugural, realizo una introducción a la frustrante situación jurídica en la que se encuentran las descargas de aguas residuales a nivel internacional. Las descargas de aguas residuales son la mayor fuente de contaminación marina y, en consecuencia, ellas representan el mayor riesgo actual para la protección del medio ambiente marino. In this opening speech, I make an introduction to the disappointing legal situation of waste water discharges at international level. Waste water discharges is the main source of marine pollution and, therefore, they represent the major current risk to the protection of the marine environment.
Green small technology for neighbourhood regeneration: a southern case-study.
2012
I rifiuti possono trasformarsi da problema ad opportunità se si transita da un’amministrazione del consumo e dello spreco ad una gestione che si proponga l’ottimizzazione nell’uso delle risorse e la valorizzazione degli scarti. Il trattamento della frazione organica dei rifiuti per la produzione di biogas, calore di processo e compost di qualità può rappresentarne un aspetto di forte rilievo. La scala di quartiere, indicata nel lavoro di ricerca che viene presentato, può consentire, per certi versi, la scomposizione della complessa realtà metropolitana e la declinazione efficiente del paradigma del principio di prossimità, dell’autosostentamento e del coinvolgimento delle comunità locali pe…
Recover and reutilization of waste matter of coffee preparation. An experiment for Environmental Science Course
2001
This work is designed as an experience for organic and analytical chemistry laboratories involved in environmental science courses. It achieves the following goals: 1. It shows that environmental samples are not homogeneous (1). 2. It is possible to build up students’ confidence in manipulating everyday matter when they are beginning to study scientific subjects and to introduce some methods of sample preparation in analytical chemistry. 3. It demonstrates some fundamental analytical principles (acid–base and redox analysis, solid–liquid and liquid– liquid extraction, etc.). 4. It shows the importance of instrumental analysis, such as gas chromatography, atomic absorption spectroscopy and e…

MUNICIPAL WASTEWATER TREATMENT IN A HYBRID ACTIVATED SLUDGE BIOFILM REACTOR: A PILOT PLANT EXPERIENCE
2008
A hybrid activated sludge/biofilm process (IFAS) was investigated. This process which contains both suspended and attached biomass, is created by introducing plastic elements as biofilm carriers material into a classical activated sludge system. This process is suitable for upgrading existing activated sludge wastewater treatment plants which are no longer able to comply with the effluent standards, and in particular in those cases where the existing plant does not nitrify or only nitrify during summer. However, the IFAS processes are relatively new and there are still uncertainties with respect to their design. A main task is to find a rational approach to the design of nitrification in hy…
