“…6). These values determined here experimentally are higher than the results obtained for these same sawdust samples, using mathematical models based on the ultimate analysis (18.8 to 19.5 MJ/kg), in the proximate analysis (18.8 to 20.7 MJ/kg), ash content (19.2 to 19.9 MJ/kg) (Rutiaga-Quiñones et al 2020), and chemical composition (20.1 to 21.0 MJ/kg) (Chávez-Rosales et al 2021). The present results were also higher than the typical values for coniferous woods (18.5 to 19.8 MJ/kg) according to the UNE-EN 14961-1 (2011) standard, and are a consequence of the raw material used, mainly the amount of lignin 20.5% to 25.8% (Chávez-Rosales et al 2021).…”

“…One possibility for the use of these lignocellulosic residues could be the production of densified biofuels, such as pellets and briquettes. Recent research carried out with pine sawdust has characterized the particle size, proximate analysis, ultimate analysis, and microanalysis of its ash , in addition to results on its basic chemical composition (ash, extractives, holocellulose, and lignin) (Chávez-Rosales et al 2021); these studies conclude that pine sawdust has the potential to make densified biofuels. No information was available on the characteristics and properties of the briquettes made at the laboratory level with sawdust from Mexican woods.…”

This research characterized briquettes made with Pinus spp. sawdust without the use of additives. For this purpose, 19 samples of sawdust from different wood industries located in five states of the Mexican Republic were used. The densification process was carried out in a vertical hydraulic piston laboratory briquette machine. The briquettes were made with 40 g of sawdust, at 50 °C, 20 kPa and pressing for 5 min. The results obtained varied as follows: moisture content (4.1% to 7.2%), density (813.9 to 1,014.4 kg/m3), volumetric expansion (7.4% to 37.3%), compressive strength (4.9 to 40.8 N/mm), impact resistance index (46.7% to 200%), ash (0.1% to 1.1%), volatile matter (82.9% to 90.7%), fixed carbon (8.9% to 16.4%), and calorific value (20.5 to 22.8 MJ/kg). The density of the briquettes was within the “acceptable” classification (800 to 1,200 kg/m3). It was observed that, the higher the density, the lower the volumetric expansion, the higher the compressive strength, and the higher the impact resistance index. According to the ash content, the briquettes could achieve international quality. Due to high volatile matter values, rapid combustion of the briquettes with little generation of toxic smoke would be expected. Fixed carbon and calorific value results were acceptable.

This study shows the energy potential of pine wood waste for the production of solid biofuels, and was carried out in an indigenous community in the state of Michoacán. One of the main economic activities of this community is the production of handcrafted furniture, which generates a large amount of wood waste. The most relevant results obtained in this research show that the community generates approximately 2268 kg of sawdust and 5418 kg of shavings per week, and the estimated energy potential per year for both sawdust is 1.94 PJ and for shaving is 4.65 PJ. Based on the particle size observed, the wood residue can be used to generate pellets or briquettes. Other average results in sawdust and (shavings) are the following: initial moisture content 15.3% (16.8%), apparent density 169.23 kg/m3 (49.25 kg/m3), ash 0.43% (0.42%), volatile material 84.9% (83.60%), fixed carbon 14.65% (15.96%), hemicelluloses 12.89% (10.68%), cellulose 52.68% (52.82%), lignin 26.73% (25.98%), extractives 7.69% (10.51%), calorific value 17.6 MJ/kg (17.9 MJ/kg). The major chemical elements in the ash were Al, K. Fe, Ca, P, Na, and Mg. Finally, the results obtained indicate that this biomass can be used to generate pellets or briquettes in this indigenous community.
