Sulla (Hedysarum coronarium L.) as Potential Feedstock for Biofuel and Protein
2016
Although sulla (Hedysarum coronarium L.) has many interesting features that could support the production of biofuels (e.g., a high yield and soluble sugar content, N-fixation capacity, low input requirements for its cultivation), no study has assessed the possibility of its use for that purpose. Our objective was to evaluate the potential value for energy production of sulla cut at various stages of growth. Furthermore, the potential of sulla as a dual purpose crop (energy and feed) was investigated. The crop was grown in rainfed conditions in a typical Mediterranean environment (over two complete 2-year crop cycles) and was cut at four different phenological stages. The biomass was divided…
One-stage H2 and CH4 and two-stage H2+ CH4 production from grass silage and from solid and liquid fractions of NaOH pre-treated grass silage
2009
Abstract In the present study, mesophilic CH4 production from grass silage in a one-stage process was compared with the combined thermophilic H2 and mesophilic CH4 production in a two-stage process. In addition, solid and liquid fractions separated from NaOH pre-treated grass silage were also used as substrates. Results showed that higher CH4 yield was obtained from grass silage in a two-stage process (467 ml g−1 volatile solids (VS)original) compared with a one-stage process (431 ml g−1 VSoriginal). Similarly, CH4 yield from solid fraction increased from 252 to 413 ml g−1 VSoriginal whereas CH4 yield from liquid fraction decreased from 82 to 60 ml g−1 VSoriginal in a two-stage compared to …
Bio-coal, torrefied lignocellulosic resources – Key properties for its use in co-firing with fossil coal – Their status
2012
Abstract Bio-coal has received generous amounts of media attention because it potentially allows greater biomass co-firing rates and net CO2 emission reductions in pulverised-coal power plants. However, little scientific research has been published on the feasibility of full-scale commercial production of bio-coal. Despite this, several companies and research organisations worldwide have been developing patented bio-coal technologies. Are the expectations of bio-coal realistic and are they based on accepted scientific data? This paper examines strictly peer-reviewed scientific publications in order to find an answer. The findings to date on three key properties of torrefied biomass are pres…
Small Island developing states: Overview about wind, solar and marine energy in Cuba
2019
The current economic, political, and social trends in Cuba indicate that energy sector will change in the future. The energy consumption will increase and Cuba, like most island nations, lacks a large energy resource base and satisfies most of its energy needs with imported fossil fuels. The aim of this work is a summary of renewable energy sources (solar, wind, bioenergy and marine) presented in the island and the development in the next society of the future.
ForBioEnergy - Forest Bioenergy in the Protected Mediterranean Areas
2019
The ForBioEnergy project, funded within the INTERREG MED Programme 2014-2020, involved a Lead Partner (Regional Department for the Rural and Territorial Development, Sicily Region), 8 project partners from 4 Mediterranean countries (Italy, Spain, Slovenia and Croatia) and 4 Associate Partners from Italy (Ente Parco delle Madonie, AIEL, Enviland, Petralia Sottana) and Croatia. It is an innovative project which bets on the chance to favor the sustainable development of the rural areas through the exploitation of the forest biomass for the production of bioenergy. However, most of the Mediterranean forests are within protected areas, where the current regulatory restrictions and the lack of ma…
Assessment of forest biomass derivable from the sustainable mana-gement of Mediterranean plantations in the Sicani mountains (Sicily)
2014
In view of an ecological and environmentally use of the biomass drew from forest operations, it is utterly important to well know the forest ecosystems characterizing the regional territory and in particular the pilot area of the Proforbiomed project. In this way it was possible to acquire specific information on the forest types in the area, its ecological and structural characteristics and the evolutionary dynamics. The information gathered have been fundamental in order to detect the most suitable forest management policies and interventions, able to put together the use of biomass and an increased of forest ecosystems stability.The studies carried out in the pilot area of the Proforbiom…
ForBioEnergy - Forest Bioenergy in the Protected Mediterranean Areas
2018
ForBioEnergy project, funded in 2016 within the INTERREG MED Programme 2014 – 2020, involves a Lead Partner (Regional Department for the Rural and Territorial Development, Sicily Region), 8 project partners from 4 Mediterranean countries (Italy, Spain, Slovenia and Croatia) and 4 Associate Partners from Italy (Ente Parco delle Madonie, AIEL) and Croatia. The other Italian partners are Enviland s.r.l. and the municipality of Petralia Sottana. ForBioEnergy is an innovative project which bets on the chance to favour the sustainable development of the rural areas through the exploitation of the forest biomass for the production of bioenergy. In Mediterranean contexts, however, most of the fores…
From the sustainable forest management to the short wood-energy supply chain: the experience of the ForBioEnergy project in the Madonie Natural Park
2019
The ForBioEnergy Project (Interreg MED Programme), implemented as part of a partnership between four countries of the MED Area (Italy, Spain, Croatia and Slovenia), assessed the possibility of producing bioenergy using biomass from the sustainable forest management in the protected areas of the Mediterranean. In Italy, the pilot protected area was the Madonie Natural Regional Park (Sicily). After the establishment of the protected area (in 1989), both for socio-economic reasons and for the regime of the constraints introduced, the silvicultural activities were almost completely abandoned. On the one hand, this has made it possible to reduce the excessive exploitation of forest resources and…
Sampling procedure in a willow plantation for chemical elements important for biomass combustion quality
2015
Willow (Salix spp.) is expected to contribute significantly to the woody bioenergy system in the future, so more information on how to sample the quality of the willow biomass is needed. The objectives of this study were to investigate the spatial variation of elements within shoots of a willow clone ‘Tordis’, and to reveal the relationship between sampling position, shoot diameters, and distribution of elements. Five Tordis willow shoots were cut into 10–50 cm sections from base to top. The ash content and concentration of twelve elements (Al, Ca, Cd, Cu, Fe, K, Mg, Mn, Na, P, Si, and Zn) in each section were determined. The results showed large spatial variation in the distribution of mos…
Organic silicon compounds in biogases produced from grass silage, grass and maize in laboratory batch assays
2013
Abstract In the present study the occurrence of volatile organic silicon compounds in biogas produced from grass silage, grass and maize in laboratory batch assays was analyzed and methane potentials were determined. Inoculum from a mesophilic farm digester was used, and its effects were subtracted. Methane yields from grass silage, grass and maize were 0.38, 0.42 and 0.34 m3CH4/kg – volatile solids added (VSadd), respectively. Trimethyl silanol, hexamethylcyclotrisiloxane (D3), octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5) were detected from all the biogases. Higher yields of volatile organic silicon compounds in the grass (from 21.8 to 37.6 μg/kgVSadd) were detec…
