Characterization of eggshell as limestone replacement and its influence on properties of modified cement
2022
Food industry is known to produce, as a side product, huge amounts of eggshell. “Green chemistry” is searching for efficient ways of recycling antropogenic waste materials including also eggshell which is composed mainly from calcium carbonate and small amount of protein membrane. It is challenging to apply powdered chicken eggshell in cement industry and replace natural limestone. The impact of organic component of eggshell on modified cement was not studied yet. In the current report experimental studies were performed on the impact of the added powdered chicken eggshell instead of limestone on cement properties. 10, 20, and 30% of powdered eggshell (by weight) was added to Portland cemen…
No externalities for closed-cycle cities. Strategic environmental assessment and planning
2017
Il testo offre alla discussione disciplinare alcune riflessioni sulla rilevanza della valutazione ambientale come componente di forte rilevanza all'interno dei processi di pianificazione, con l'obiettivo di eliminare il concetto di "esternalità" nei processi di pianificazione-valutazione. Il contributo fa riferimento ad alcuni casi studio e sperimentazioni condotte nel corso degli ultimi anni in Sicilia. The paper offers some discussion of the importance of environmental assessment as a major component of planning processes, with the aim of eliminating the concept of "externality" in planning and evaluation processes.
