Scorpiurus muricatus L.: an interesting legume species for Mediterranean forage systems
2017
Scorpiurus muricatus L. (prickly scorpion’s tail) is a legume species widely distributed as a spontaneous plant in Mediterranean pastures. In Sicily, farmers ascribe to this species a very high palatability and galactogogue effect, so that its abundance increases the value of the pasture. However, despite its worthy traits, the use of S. muricatus as a forage within cropping systems has not been well investigated. A field experiment was performed during two growing seasons in a semiarid Mediterranean environment to acquire information on the productivity of S. muricatus in comparison with other forage species grown in Mediterranean areas (e.g. berseem clover, burr medic, subterranean clover…

Gestione sostenibile delle foreste Mediterranee e uso energetico delle biomasse forestali residuali
2014
he book describes the reasons that led the Regional Department of Rural and Territorial Development to take part in the PROFORBIOMED Project. They can be summarized by the need to dispose of a tool for the sustainable management of all the state-owned forests of the Region. As a matter of fact, the Project aims at developing a model of sustainable forest management, through the recovery and reuse of wood scraps from ordinary silvicultural operations, to be used for the production of power and heat inside of a process adopting natural renewable energy sources. The main actions taken and the methodologies adopted are described, as well as the principles and instruments required for the settin…
Caratterizzazione bio-agronomica ed energetica di alcune specie presenti nella flora spontanea siciliana
2009
La biomassa ligno-cellulosica, proveniente da numerosi arbusti della macchia mediterranea, grazie alla loro diffusa disponibilità sul territorio, rappresenta sicuramente una fonte rinnovabile di energia facilmente reperibile. Il crescente interesse verso tali fonti ha sollecitato la ricerca ad approfondire le conoscenze su quelle specie che, da un lato possano fornire una notevole quantità di biomassa, dotata di un elevato rendimento energetico, e che, dall’altro, richiedono bassi input energetici (concimazioni, lavorazioni, apporti irrigui, ecc.) per la loro coltivazione. In quest’ottica, è stato svolto uno studio per individuare specie arbustive della macchia mediterranea, contribuendo co…
INDIVIDUAZIONE DI POLI ENERGETICI PER LA VALORIZZAZIONE DELLE BIOMASSE NELLA SICILIA OCCIDENTALE
Bioresource technology for bioenergy, bioproductsenvironmental sustainability.
2022
The 3rd International Conference for Bioresource Technology for Bioenergy, Bioproducts & Environmental Sustainability (BIORESTEC) was held online from 17 to 19 May 2021. More than 120 participants from all over the world participated in this conference. The conference was studded with nine plenary lectures, ten invited lectures as well as more than 50 oral presentations along with several poster presentations. The purpose of the conference was to foster the exchange of knowledge and ideas among researchers in academia and industry as well as policymakers working on various aspects of biorefinery to discuss the progress made during the intervening three years and the latest trends in bio…
Bisphenol A removal from water by biomass-based carbon: isotherms, kinetics and thermodynamics studies
2018
Biomass-based carbon was modified and used as an efficient bisphenol A (BPA) sorbent. The simple and environmentally friendly modification method produced sorbent with a capacity of 41.5 mg/g. The ...
Reed canary grass transportation costs – Reducing costs and increasing feasible transportation distances
2009
Abstract Reed canary grass is used in several heat and power plants in Finland and it is estimated that about 70–80 plants could utilise reed canary grass as a co-firing fuel. Long-distance transport of reed canary grass forms a significant share of the production and delivery costs. Reed canary grass can be transported in bales or as loose matter. The density of the matter and shape of the bales influence the load-size and the cost. At present it is impossible to obtain the full load-bearing capacity of a lorry even with bales, and with light bulk matter the obtainable load is less than one-third of the load-bearing capacity of a lorry. By using Orkel local-baler it has been possible to ob…
Brønsted and Lewis acid catalyzed conversion of pulp industry waste biomass to levulinic acid
2019
Enormous amounts of fiber sludge are generated annually by the pulp industry as a by-product. As a cellulose-rich material, its current usage, mainly as fuel, is inefficient from a material efficiency point of view. This work studied the utilization of fiber sludge from a Finnish and a Swedish pulp mill as a potential feedstock to produce levulinic acid, a valuable platform chemical. The conversion experiments of fiber sludge to levulinic acid were performed in a microwave reactor with a mixture of H2SO4 and Lewis acid as the catalyst. The reaction conditions, which included reaction time and temperature as well as the H2SO4 and Lewis acid concentrations, were studied in detail. The highest…
Long‐Term Tillage and Cropping System Effects on Chemical and Biochemical Characteristics of Soil Organic Matter in a Mediterranean Semiarid Environm…
2015
Several studies have reported how tillage and cropping systems affect quantity, quality, and distribution of soil organic matter (SOM) along the profile. However, the effect of soil management on the chemical structure of SOM and on its hydrophobic and hydrophilic components has been little investigated. In this work, the long-term (19 years) effects of two cropping systems (wheat monoculture and wheat/faba bean rotation) and three tillage managements (conventional, reduced, and no tillage) on some chemical characteristics of SOM and their relationships with labile carbon (C) pools were evaluated. Soil samples were taken from the topsoil (0–15 cm) of a Chromic Haploxerert (central Sicily, I…
