“…These results show that the ash content is higher in the branches fraction than in the biomass from the timber stage [57,58] which decreases its quality as a fuel residue compared to wood. However, the ash content of the samples analyzed is much lower than that presented by some coals [51].…”

“…High percentages (>70%) of VM were obtained from the analyzed forest residues. Such high values show the potential of these percentages in gasification processes, which is much higher than the content in coal volatile matters (30.52 and 44%) [48,51]. The fixed content ranged from 14.92 to 18.55% for the FBR of E. globulus and P. radiata, respectively.…”

“…Another reference [51] gave the N weight percentage as 1.55%, and in [48], the N amount was shown to be 1.9% in different types of coal. In [51], the sulphur content was around 0.26% in Australian bituminous coal (WH), while in [48], a value of 0.5% was reported for coal.…”

The substitution of energy based on fossil fuel by bioenergy could be an effective solution to reduce external energy dependency, thereby promoting sustainable development. This article details a study of the use of biomass residues produced in the forestry sector as a consequence of field operations of the two predominant forest species (Pinus radiata D. Don and Ecualyptus globulus Labill) of Biscay (Spain). The potential of forest residues is estimated to be 66,600 dry Mg year − 1 . These residues would provide 1307 TJ year − 1 . Energy parameters, ultimate and proximate analyses, and the level of emissions of the forest residues are performed in order to estimate their characteristics as fuel. The research done has shown very similar values in terms of the net calorific value of the residues of P. radiata (19.45 MJ kg − 1 ) and E. globulus (19.48 MJ kg − 1 ). The determined emission factors indicate a reduction in gas emissions: CO (23–25%), CO 2 (22–25%), SO 2 (87–91%) and dust (11–38%) and an increase of 11–37% in NO x compared to hard coal. Estimation of the emission factors of the residual biomass allows the environmental impacts, that are potentially produced by biofuel, to be estimated.

Summary Over the last few decades, the significant increase in energy demand followed by increasing fossil fuels depletion convinced countries authority to choose renewable energy to satisfy demand. Therefore, global enthusiasm in renewable energy such as bioenergy technology is increased. Is biofuels technology ready to address the global demand for energy? Investigating in technology development can answer. In this paper, the current statuses of biofuel technologies are determined. Regarding patent codes, seven technologies are identified, which are CHP turbines for biofeed, gas turbine for biofeed, biodiesel, grain bioethanol, bio‐pyrolysis, torrefaction of biomass, and cellulosic bioethanol. The results of patent investigating show that the biodiesel technology is in the mature status and its technology trend is going to go downward. The others six technologies are in the growth stage. Analysis of 57 619 patents in biofuel technologies for technology forecasting has been done by technology life cycle. The torrefication of biomass technology has started its growth stages and will become mature in 2061. In this research, the S‐curves of all biofuel groups are plotted and maturity phases are forecasted.

“…High CO emission during co‐combustion contributes to the decrease of NOx emission . Moreover, there is an interactive effect of co‐combustion on NOx emission in air and O 2 /CO 2 combustion . Wei et al indicated that the ideal cofiring biofuel to reduce NOx emission had a low nitrogen content and a high volatile content.…”
