Almond shell reuse: a viable non-conventional aggregate for sustainable building materials

2022

Bio-based or green architecture is a new way of designing and building in line with the European Green Deal and in light of the Circular Economy principles. The main green approach directs the whole construction life cycle to be eco-sustainable and environmentally friendly from the beginning to the end of the building process. Beyond the use of eco sustainable and highly performing structural materials, new technologies able of reduce the environmental impact of buildings must be used. This paper is aimed at reviewing the possible reuse of bio- wastes of agricultural origin whose massive production generates a number of issues for their treatment and disposal. In particular, this study will…

A critical approach to the toxic metal ion removal by hazelnut and almond shells

2018

The adsorption capacity of ground hazelnut (HS) and almond (AS) shells towards Pb(II) and Cd(II) has been studied at pH = 5, in NaNO3 and NaCl ionic media, in the ionic strength range 0.05-0.5 mol L-1. Kinetic and equilibrium experiments were carried out by using the Differential Pulse Anodic Stripping Voltammetry technique to check the amount of the metal ion removed by HS and AS materials. Different kinetic and equilibrium equations were used to fit experimental data and a statistical study was done to establish the suitable model for the data fitting. A speciation study of the metal ions in solution was also done in order to evaluate the influence of the ionic medium on the adsorption pr…

Development of New Bio-based Materials Derived from Sicilian Agri-Food Industry Waste

2023

La necessità di soluzioni di materiali da costruzione a base biologica e sostenibili è aumentata drammaticamente nell’ultimo ventennio. Questa ricerca esplora i possibili modi per riutilizzare materiale di scarto a base biologica (come i gusci della frutta secca), derivati dall'industria agroalimentare, per la produzione di nuovi materiali da costruzione sani in linea con i principi dell'economia circolare. L’analisi di alcuni casi di studio precedenti e le attuali ricerche dimostrato la possibilità di riutilizzare i gusci della frutta secca per la realizzazione di nuovi componenti edilizi. Le attuali tendenze mostrano che le resine sintetiche sono sempre più usati come legante per incollar…
