“…In agreement with the gasification results, the energetic values of the biomass obtained in our study (ranging 16.7 to 18.4 MJ kg -1 ) were slightly lower than those found in other studies with Paulownia plants grown in different plantations across Spain (18.3-20.3 MJ kg -1 ; López et al, 2012;Villanueva et al, 2011), but improved when organic materials were applied to the soils (Table 5). Although woody biomass has a higher lignin and cellulose content than herbaceous biomass, leading to higher calorific value, the gross calorific values of the biomass obtained in this study were similar to those found in food plant residues and straw (16.7-17.8 MJ kg -1 , Naik et al, 2010;Wang et al, 2011), and lower than the typical calorific values reported for softwood and hardwood (20 MJ kg -1 and 18 MJ kg -1 , respectively; López et al, 2011;Telmo et al, 2010).…”

This is likely due to the relatively lower lignin content in the one to two-year-old plants used in this study, in comparison with other studies using older plants, given that the accumulation of lignin, with a higher calorific value than cellulose, increases with age (Villanueva et al, 2011).…”

The plantation of fast growing trees in contaminated sites, in combination with the use of organic wastes, could partially solve a dual environmental problem: the disposal of these wastes and the improvement of soil quality in these degraded soils. This study evaluated the effects of two composts amendments on the quantity and quality of Paulownia fortunei biomass and on syngas production by biomass gasification, produced by plants growing on trace elements contaminated soils. Compost increased biomass production to values similar to those produced in non-contaminated soils, due to the improvement in plant nutritional status. Moreover, biomass quality for gasification was increased by compost addition. Trace element accumulation in the biomass was relatively low and not related to biomass production or the gas quality obtained through gasification. Thus, P. fortunei plantations could pose an opportunity to Preprint submitted to Elsevier 2 improve the economic balance of the revegetation of contaminated soils, given that other commercial uses such as food or fodder crop production is not recommended in these soils.

“…Ash content in this study ranged from 0.5 to 1.1 % for the stemwood component (average 0.76 %), values in line with the those established for woody species (Senelwa & Sims 1999, Kumar et al 2010, Villanueva et al 2011, which are considerably lower than for herbaceous species (Jenkins et al 1998, McKendry 2002. The average percentage of ash is lower in E. nitens than in other Eucalyptus species such as E. globulus (Senelwa & Sims 1999, Pérez et al 2006 resulting in two advantages: a lower quantity of nutrients needs to be provided to the soil, and less maintenance required in boilers.…”

“…The most suitable energy crop species should combine high production with high quality biomass (Kumar et al 2010), and Eucalyptus have higher energy potential than other fast growing energy species such as Populus and Pawlonia (Villanueva et al 2011). Within the Eucalyptus genus the energy potential of residual biomass (tree fractions obtained from wood harvesting that are not used for wood or pulp production) has been found to be higher for E. nitens than for E. globulus in northern Spain (Pérez et al 2006).…”

This study provides essential information related to the nutrient and carbon levels and the energy potential of Eucalytpus nitens (Deane & Maiden) Maiden bionenergy plantations located in northwestern Spain. Nutritional analysis showed that leaves and bark had the highest concentrations of N, P, K and Mg. Carbon concentration was constant for all above-ground tree components. Nutrients and carbon were analyzed at stand level according to plantation productivity. Stemwood, the main tree component at the end of the rotation, had the highest nutrient content, except for N and Ca, which were highest in leaves and bark respectively. . The results obtained are valuable for selecting the most appropriate forest management system in these bioenergy plantations, and thereby promote the sustainable use of woody crops.

“…In particular, TG can monitor the sample mass of substance as a function of temperature and/or time, whereas DTG is an approach performed by detecting the rate of mass loss. These two approaches have been used recently in thermal degradation of biomass samples (Eero, 1981;Jakab et al, 1997;Meszaros et al, 2007;Sebestyén et al, 2011;Shafizadeh, 1968;Varhegyi et al, 1988;Villanueva et al, 2011;Wilson et al, 2011), investigations of sewage sludge pyrolysis (Dumpelmann et al, 1991;Magdziarz and Werle, 2014), and combustion (Font et al, 2001;Magdziarz and Wilk, 2013), as well as co-combustion of sewage sludge and other substances (Otero et al, 2002;Park and Jang, 2011;Yu and Li, 2014). Operation parameters of SCPs, such as temperature and atmosphere conditions, were also evaluated using both TG and DTG approaches (Calvo et al, 2013;Manara and Zabaniotou, 2012).…”

a b s t r a c tWastewater treatment plants produce millions of tons of sewage sludge. Sewage sludge is recognized as a promising feedstock for power generation via combustion and can be used for energy crisis adaption. We aimed to investigate the quantitative effects of various sludge characteristics on the overall sludge combustion process performance. Different types of sewage sludge were derived from numerous wastewater treatment plants in Beijing for further thermogravimetric analysis. Thermogravimetric-differential thermogravimetric curves were used to compare the performance of the studied samples. Proximate analytical data, organic compositions, elementary composition, and calorific value of the samples were determined. The relationship between combustion performance and sludge composition was also investigated. Results showed that the performance of sludge combustion was significantly affected by the concentration of protein, which is the main component of volatiles. Carbohydrates and lipids were not correlated with combustion performance, unlike protein. Overall, combustion performance varied with different sludge organic composition. The combustion rate of carbohydrates was higher than those of protein and lipid, and carbohydrate weight loss mainly occurred during the second stage (175-300°C).Carbohydrates have a substantial effect on the rate of system combustion during the second stage considering the specific combustion feature. Additionally, the combustion performance of digested sewage sludge is more negative than the others.
