Abstract
Abstract Woody biomass has a considerable potential for energy purposes specially after densification processes which convert these materials into solid biofuels with higher energy density. This study focuses on the energy and environmental assessment of pellet production system from vine and olive grove woody biomass. The life cycle assessment (LCA) from grape and olive cultivation up to packed pellet production, ready for delivery to final users was conducted to quantify the eco-profile of agro-pellet production. The results of comparative analysis revealed that pellet production from both biomasses is dominated by cultivation phase. Vine pellet production was more dependent on chemical fertilizers specially potassium sulfate, but olive pellet production was more dependent on copper oxide pesticide. Primary energy use per MJ energy of vine pellet was greater than that of olive pellet (0.6 vs. 0.19). On the other hand, energy return ratio of olive pellet was three times of that of vine pellet (5.22 vs. 1.7). Nevertheless, olive pellet had higher environmental impacts in the forms of human toxicity, freshwater ecotoxicity and marine ecotoxicity. Consequently, sensitivity analysis investigates the impact of variation in input parameters of fertilizers, pesticides, machinery, diesel fuel, transport and pelletizing process on LCA results.

Abstract Life-cycle assessment (LCA) and data envelopment analysis (DEA) were combined in the environmental sustainability assessment of bioelectricity production by means of vineyard waste biomass gasification. Fifty vineyards were assessed following LCA and DEA methodologies to estimate their technical efficiency. Moreover, target performance values benchmarked for inefficient vineyards, and the potential reductions in their environmental impact linked to the improvement in technical efficienc...

This study evaluates the environmental profile of a real biomass-based hydrogen production small-scale (1 MWth) system composed of catalytic candle indirectly heated steam gasifier coupled with zinc oxide (ZnO) guard bed, water gas shift (WGS) and pressure swing absorber (PSA) reactors. Environmental performance from cradle-to-gate was investigated by life cycle assessment (LCA) methodology. Biomass production shows high influence over all impact categories. In the syngas production process, the...

Abstract This paper investigates the environmental performance of a multifunctional bioenergy chain for the provision of domestic heat using Life Cycle Assessment methodology. The analysis is based on a commercial pellet plant located in Spain and incorporating a Combined Heat and Power system based on Organic Rankine Cycle technology that also produces electricity that is sold to the grid. The base scenario involves using pine wood both from forests and wood processing activities. This situatio...

Acknowledging the absence of up-to-date empirical data on the value retention, service life and annual use of chipping machinery, in 2017 the authors surveyed the records kept by 50 contractors offering biomass chipping services. The machine fleet and operations in this survey could be taken as representative for most of Europe, where the biomass sector is well established and is facing further expansion. Data collection included the whole chipping unit, comprised of chipper, carrier and loader....

Abstract Biomass is the renewable resource with the potential to serve as a substitute for fossil fuels. A form of biomass, woody residues, includes woody byproducts such as mill residues, logging residues, and other wood waste. This study estimated the impact of woody residue processing capacity, mill willingness to utilize additional logging residues for electricity production, mill equipment upgrades to facilitate electricity production, and different factors limiting the utilization of loggi...

Abstract Standard ISO Life Cycle Assessment methodology was applied to the production of wheat and maize in an Italian farmers' cooperative, with the aim to assess the potential environmental impacts throughout the life cycle of these crops as well as to identify the hotspots in the production chains. The functional units were 1 tonne of wheat and maize, respectively and system boundaries were from cradle to cooperative's gate, including the agricultural production, the transport to the cooperat...

Abstract The use of biomass for energy production is one of the promising alternatives identified by the European Union to reduce greenhouse gas emissions and to ensure energy supply security. The aim of this research is to analyse the potential energy production from pruning residues of vineyards and olive groves in four municipalities of the Umbria Region, along with its economic and environmental sustainability. Geo-spatial, economic and environmental analyses were carried out. The integrated...

Sumatriptan nasal powder delivered by a breath powered delivery device (ONZETRA® Xsail®) is indicated for the acute treatment of migraine with or without aura in adults. This narrative review discusses the clinical use of sumatriptan nasal powder in this population and summarizes its pharmacological properties. In migraineurs, sumatriptan nasal powder treatment was associated with significantly greater rates of pain relief than placebo from 0.5–2 h postdose after a single treatment in the phase ...

Abstract The present study aims to quantify the main biomass resources in South Tyrol (Northern Italy) and estimate the potential contribution for the energy sector. Moreover, four representative feedstocks have been tested in a domestic pellet boiler under standard conditions in order to assess its performance and pollutant emissions. The unexploited biomass potential for energy conversion applications, expressed as dry weight, has been estimated to be 135 000 t y −1 from forest, 14 950 t y −1 ...

Forests play a key role as the source of an essential renewable material and/or fuel: wood. The aim of this study was to evaluate the environmental impacts related to high-quality pellet production for domestic heating following the LCA (life cycle assessment) methodology and considering a cradle-to-gate perspective in the Tuscany region. This is representative and interesting for Italian pellet factories and for similar factories located in Central Europe, considering the Italian contribution t...
