“…All conifers in this study were within the range (0.1% to 1.1%) reported for pine sawdust (Ramírez-Ramírez et al 2021). In general, ash content in conifers is lower than in broadleaved hardwoods, which coincides with the study by Gutiérrez-Acosta et al (2021). The ash content in biomass influences fuel quality and higher content decreases the calorific value (Demirbaş and Demirbaş 2009, Klašnja et al 2013, Martínez-Pérez et al 2015, Ngangyo-Heya et al 2016, Ruiz-Aquino et al 2019.…”

The potential use of forest species as fuels depends on their energy quality. However, in rural communities in developing countries, fuelwood is still an energy source without any technical study evaluating its energetic characteristics. Therefore, this study aimed to analyze the energetic characteristics of 22 forest species from four communities in the state of Oaxaca, Mexico. The basic wood density, proximal analysis, and high heating value were evaluated. As a result of the analysis, the fuel number (FN) is proposed as a measure of the energy quality of biomass fuels in the form of firewood. FN considers the basic wood density, the fixed carbon, and the high heating value of each species. Wood basic density ranged from 0.472 g·cm-1 for Pinus pseudostrobus to 0.814 g·cm-3 for Dodonaea viscosa, fixed carbon ranged from 4.74% to 21.27% for Liquidambar styraciflua and Quercus rugosa, respectively, and high heating value from 18.33 MJ·kg-1 to 22.07 MJ·kg-1 for Liquidambar styraciflua and Pinus leiophylla, respectively. Classifying wood according to FN, in decreasing order, Quercus rugosa stands out as the best wood (66.97%), followed by Liquidambar styraciflua (39.52%). Regarding the fuel value index, the nine pine species showed the highest values (27.32 to 77.76). The FN provides a measure of the quality of biomass fuels in the form of firewood, and can be evaluated by easily measured variables.

“…They also obtained a larger interval (18.4–19.2 MJ/kg) than the one registered for latifoliate woods in UNE-EN ISO 17225-1 [ 41 ]. It is important to emphasize that the results for the caloric value obtained herein with the methodologies utilized are within the interval of 18.13–21.7 MJ/kg estimated for various species of latifoliate woods in Mexico [ 27 , 42 ]. According to international parameters ( Table 3 ), the calorific value higher than of P. laevigata wood is above the quality parameter.…”

Diverse methodologies exist to determine the chemical composition, proximate analysis, and calorific value of biomass. Researchers select and apply a specific methodology according to the lignocellulosic material they study and the budgetary resources available. In this project, we determined the primary chemical constitution and proximate analysis of Prosopis laevigata (Humb. & Bonpl.) Jonhst wood using a traditional chemical method and a novel procedure based on the deconvolution of the DTG signal produced by TGA. The highest calorific value was verified using a calorimetric pump based on mathematical models. We also conducted elemental analysis and a microanalysis of ash, and applied Fourier transform infrared spectroscopic analysis (FT-IR). The means of the results obtained by the chemical method and TGA-DTG, respectively, were: hemicelluloses 7.36%–(8.72%), cellulose 48.28%–(46.08%), lignin 30.57%–(32.44%), extractables 13.53%–(12.72%), moisture 2.03%–(4.96%), ash 1.77%–(1.90%), volatile matter 75.16%–(74.14%), and fixed carbon 23.05%–(18.93%). The procedure with the calorimetric pump generated a calorific value above 20.16 MJ/kg. The range generated by the various models was 18.23–21.07 MJ/kg. The results of the elemental analysis were: carbon 46.4%, hydrogen 6.79%, oxygen 46.43%, nitrogen 0.3%, and sulfur 0.5%. The microanalysis of ash identified 18 elements. The most abundant ones were potassium ˃ calcium ˃ sodium. Based on the infrared spectrum (FT-IR) of Prosopis laevigata wood, we detected the following functional groups: OH, C-H, C=O, CH2, CH3, C-O-C, C-OH, and C4-OH. Our conclusion is that the TGA-DTG method made it possible to obtain results in less time with no need for the numerous reagents that chemical procedures require. The calorific value of P. laevigata wood is higher than the standards. Finally, according to our results, proximate analysis provides the best model for calculating calorific value.

“…Plant biomass can be used as compost (Stabnikova et al 2005;Alvarenga et al 2015) and as a dewatering aid for sewage sludge (Lin et al 2001a,b;Jaafarzadeh et al 2016). Furthermore, it can be used in methane production via co-anaerobic fermentation with sludge (Koch et al 2009;Hidaka et al 2013) and combusting fuels in an incinerator (Hurskainen and Vainikka 2016;Gutiérrez-Acosta et al 2021). Thus, a wastewater treatment plant (WWTP) with an intense treatment system using this plant biomass is desirable.…”

Large amounts of plant biomass are produced by public work projects. This plant biomass was evaluated as an aid for the dewatering of sludge from a sewage treatment plant. The relationships were investigated between the different structural types of plant biomass (grass clippings, pruned branches of Japanese black pine, and bamboo powder) and their dewaterability potential in digested sludge. Microscopic observations revealed that grass fibrous materials and Japanese black pine needles had hollow structures. However, xylem, bark parts of Japanese black pine, and bamboo culms exhibited woody cell structures. The difference in water retention value of grass clippings after filtration and centrifugation was higher than that of Japanese pine and bamboo, indicating that the water present within the pores of grass fibrous materials could be easily removed. Plant biomass was captured inside the floc when digested sludge was mixed with plant biomass and flocculation was performed by adding a flocculant. The addition of grass clippings exhibited better dewaterability compared with both Japanese black pine and bamboo. The grass fibrous materials used as a dewatering aid effectively improved the dewaterability of the digested sludge because the water in a sludge floc may be drained from within the grass fibrous materials.
