Uso dei beni culturali

2019

The juridical analysis of the evolution of the discipline of the use of the cultural heritage is directed to demonstrate the partial gaps that the administrative function of the valorization maintains in the context of the Italian order, under the profile of the insufficient normative support to the actions and interventions of the public administration to support the promotion of culture and private participation in cultural policies

HISTORIC CITIES AND INNER AREAS IN SICILY The point of view of the Restoration

2022

The discipline of restoration has long established a cultural background on the subject of historic cities as a heritage area to be safeguarded, beginning with the Amsterdam Declaration (1975), which introduced the fundamental concept of «integrated conservation». The purpose of this contribution is to emphasize the importance of raising an awareness and care for heritage as a community identity card and not just a reason for tourist offer. The territory and cultural heritage thus become a pedagogical challenge in defining a model of heritage enjoyment, for the promotion of local contexts and in the constitution of learning communities in which restoration likewise participates.

PBAT Based Composites Reinforced with Microcrystalline Cellulose Obtained from Softwood Almond Shells

2021

This study explores the processability, mechanical, and thermal properties of biocompostable composites based on poly (butylene adipate-co-terephthalate) (PBAT) as polymer matrix and microcrystalline cellulose (MCC) derived from softwood almond (Prunus dulcis) shells (as-MCC) as filler at two different weight concentration, i.e., 10 wt% and 20 wt%. The materials were processed by melt mixing and a commercial MCC (c-MCC) was used as filler comparison. The fibrillar shape of as-MCC particles was found to change the rheological behavior of PBAT, particularly at the highest concentration. The melt mixing processing allowed obtaining a uniform dispersion of both kinds of fillers, slightly reduci…

Life Cycle Environmental Assessment of Energy Valorization of the Residual Agro-Food Industry

2021

This study assesses the potential environmental impacts related to the energy valorization of agro-food industry waste thought the Life Cycle Assessment methodology (ISO 14040). The system examined consists of a real anaerobic digester coupled with a combined anaerobic digester and heat and power plant (AD-CHP) operating in Sicily. The analysis accounts for all the impacts occurring from the delivery of the biomass to the AD-CHP plant up to the electricity generation in the CHP. The main outcomes of the study include the eco-profile of the energy system providing electricity and the assessment of the contribution of each life cycle phase aimed at identifying the potential improvement area. …

Reprocessed polylactide: Studies of thermo-oxidative decomposition

2012

The combustion process of virgin and reprocessed polylactide (PLA) was simulated by multi-rate linear non-isothermal thermogravimetric experiments under O2. A complete methodology that accounted on the thermal stability and emission of gases was thoroughly developed. A new model, Thermal Decomposition Behavior, and novel parameters, the Zero-Decomposition Temperatures, were used to test the thermal stability of the materials under any linear heating rate. The release of gases was monitored by Evolved Gas Analysis with in-line FT-IR analysis. In addition, a kinetic analysis methodology that accounted for variable activation parameters showed that the decomposition process could be driven by …

VALORIZATION OF ANCHOVY FISHBONE WASTES FOR THE PREPARATION OF BIOPOLYMERIC BASED GREEN COMPOSITES FOR FOOD PACKAGING APPLICATIONS

Energy harvesting by waste acid/base neutralization via bipolar membrane reverse electrodialysis

2020

Bipolar Membrane Reverse Electrodialysis (BMRED) can be used to produce electricity exploiting acid-base neutralization, thus representing a valuable route in reusing waste streams. The present work investigates the performance of a lab-scale BMRED module under several operating conditions. By feeding the stack with 1 M HCl and NaOH streams, a maximum power density of ~17 W m−2 was obtained at 100 A m−2 with a 10-triplet stack with a flow velocity of 1 cm s−1, while an energy density of ~10 kWh m−3 acid could be extracted by a complete neutralization. Parasitic currents along feed and drain manifolds significantly affected the performance of the stack when equipped with a higher number of t…

Un esperimento d’illuminazione per il Tempio di Hera a Selinunte / An experiment of lighting of Temple of Hera in Selinunte

2010

Questo contributo sul tema della Permanenza e l'innovazione nell'architettura mediterranea, indaga sulle possibilità offerte, in particolare, dal campo della illuminazione artificiale innovativa applicata ai Beni Culturali. La mediterraneità può essere rivelata da diversi livelli di interpretazione sempre attuali nella questione tra tradizione e innovazione. Il caso di studio riguardante il Tempio di Hera, nel Parco Archeologico di Selinunte, è un caso limite sull'uso sperimentale della luce che sottolinea la complessità del contesto e marca la carenza di strategie di intervento affidabili. This contribution to theme on Permanence and innovation in Mediterranean Architecture, investigates a…

Amino acid-based cholinium ionic liquids as sustainable catalysts for pet depolymerization

2021

Chemical recycling to monomers is one of the key strategies in tackling the issues deriving from persistent plastic pollution in the environment, and poly(ethylene terephthalate) (PET) is among the most used polymers in modern society. In this context, we herein describe the glycolysis of PET to bis-hydroxyethyl terephthalate (BHET), promoted by basic cholinium salts differing for the anions, also comprising amino acid anions. We investigated the optimal reaction conditions, finding that the best-performing catalyst is [Ch][Gly], in the presence of which a conversion of 85% and a yield of 51% are achieved at 150 °C after 6 h, from PET deriving from a clear water bottle. We used our protocol…

Managing Municipal Solid Waste: Energetic and Environmetal Comparison among different options

2001

Goal. This research aims to assess the environmental effects of integrated strategies in a municipal waste management system. In particular, analysis is focused on a waste stream in Palermo, where landfill involves the prompt disposal of the most waste after collection. The current local management system is compared with two integrated waste management alternatives. Both the options comply with Italian regulations, but each one predicts adopting the available technologies in different ways. Methods and objectives. Energetic and environmental balances are carried out in each management system referring to local waste composition in order to quantify energy consumption, the recovery of mater…
