“…These results are similar to those obtained in this study for Q. sideroxyla, which obtained values for cellulose between 51.81% and 53.90%. The results regarding the holocellulose content (53.50-64.02%) were higher than the values reported for the Fagus species (34.40%) [84].…”

This study aimed to evaluate and compare the relationship between chemical properties, energy efficiency, and emissions of wood and pellets from madroño Arbutus xalapensis Kunth, tázcate Juniperus deppeana Steud, and encino colorado Quercus sideroxyla Humb. & Bonpl. in two gasifiers (top-lit-up-draft (T-LUD) and electricity generation wood camp stove (EGWCS)) in order to determine the reduction of footprint carbon. In accordance with conventional methodologies, we determined the extracts and chemical components (lignin, cellulose, holocellulose), and the immediate analyses were carried out (volatile materials, fixed carbon, ash content and microanalysis of said ash), as well as the evaluation of emission factors (total suspended particulate matter (PM2.5), CO, CO2, CH4, black carbon (BC), elemental carbon (EC), and organic carbon (OC)). The results were statistically analyzed to compare each variable among species and gasifiers. The raw material analyzed showed how the pH ranged from 5.01 to 5.57, and the ash content ranged between 0.39 and 0.53%. The content values of Cu, Zn, Fe, Mg, and Ca ranged from 0.08 to 0.22, 0.18 to 0.19, 0.38 to 0.84, 1.75 to 1.90, and 3.62 to 3.74 mg kg−1, respectively. The extractive ranges from cyclohexane were 2.48–4.79%, acetone 2.42–4.08%, methanol 3.17–7.99%, and hot water 2.12–4.83%. The range of lignin was 18.08–28.60%. The cellulose content ranged from 43.30 to 53.90%, and holocellulose from 53.50 to 64.02%. The volatile material range was 81.2–87.42%, while fixed carbon was 11.30–17.48%; the higher heating value (HHV) of raw material and pellets presented the ranges 17.68–20.21 and 19.72–21.81 MJ kg−1, respectively. Thermal efficiency showed statistically significant differences (p < 0.05) between pellets and gasifiers, with an average of 31% Tier 3 in ISO (International Organization for Standardization) for the T-LUD and 14% (ISO Tier 1) for EGWCS, with Arbutus xalapensis being the species with the highest energy yield. The use of improved combustion devices, as well as that of selected raw material species, can reduce the impact of global warming by up to 33% on a cooking task compared to the three-stone burner.

“…Fixed carbon represents the mass of organic matter that remains after moisture and volatile material release due to increasing biomass temperature in this analysis. It plays a crucial role in energy applications, as almost all fixed carbon forms carbon dioxide during combustion reactions [49]. Elemental values of C, H, O, N, and S and the higher calorific value obtained through calorimetry are displayed in Table 2.…”

In 2021, Mexico produced approximately 24.2 million tons of white corn, generating 3.6 million tons of corn cob residue. The final disposal of corn cob poses an environmental challenge in certain regions. This study examines the technical–economic feasibility and the greenhouse gas (GHG) mitigation potential of integrating a small-scale cogenerating gasifier fueled by corn cob into a nixtamalized corn flour manufacturing small and medium-sized enterprise (SME). This integration enables the generation of heat and electricity from the produced synthesis gas. Moreover, the process yields residual carbon, which can be used as biochar for soil restoration and removing atmospheric CO2. This option holds significance for the corn flour agroindustry in Mexico, as, in 2021, it consumed approximately 601.9 GWh of electrical energy and 938,279 GJ of thermal energy from LP Gas in its manufacturing processes to produce 2.6 million tons of nixtamalized white corn flour. These processes contributed to a total emission of 410,232 tons of CO2 into the atmosphere. The findings of this study demonstrate a cumulative reduction of 51.7% in CO2 emissions, resulting in economic benefits of USD 85,401 in 2017 for a case study SME that annually produces 1039 tons of corn flour. This study reveals the integration of a gasifier–cogenerator system fueled by corn cob as an economically viable low-carbon technology in the corn flour manufacturing industry.

“…El contenido de cenizas y de volátiles fueron determinados siguiendo la Norma española UNE-EN ISO 18122:2015 y UNE-EN ISO 18123:2015 respectivamente. Finalmente, el contenido de carbono fijo se obtuvo mediante la utilización de la ecuación (1) la cual considera el valor del contenido de ceniza y de compuestos volátiles [15] .…”

Los residuos agrícolas poseen características energéticas y son considerados como fuentes renovables, mediante procesos de conversión como la combustión, permiten la obtención de energía sustitutiva de la energía hidrocarburífera. Se evaluó energéticamente la biomasa residual agrícola de los cultivos de papa (Solanum tuberosum), maíz (Zea mays) y tomate de árbol (Solanum betaceum) como recurso renovable en la provincia de Tungurahua, Ecuador. Los cultivos prospectivos con mayor relevancia en cuanto a los residuos biomásicos generados fueron establecidos. Se propuso una base de datos del análisis proximal. Se determinó el poder calorífico y la cantidad de biomasa para el cálculo del potencial energético para la producción de energía limpia. Se determinó que el cultivo de tomate de árbol genera mayor cantidad de residuos agrícolas con 128.83 tn.ha/año, cuyo poder calorífico es de 15010.15 MJ/tn. Con estos parámetros se calculó el potencial energético que fue de 0.54 GWh.
