“…Several techniques have been developed to facilitate the transportation and improve the conversion rate of forest biomass, like mechanical processing of biomass into granular substance (pellet). Pelleting of forest biomass improves its density and reduces water content (Valdés et al, 2018). Density and moisture are two critical properties of biomass affecting (Campbell and Mika, 2009) combustion efficiency.…”

Biomass plays a crucial role in mitigating the concerns associated with increasing fossil fuel combustion. Among various types of biomass, forest biomass has attracted considerable attention given its abundance and variations. In this work, an overview is presented on different pathways available to convert forest biomass into bioenergy. Direct use of forest biomass could reduce carbon dioxide emissions associated with conventional energy production systems. However, there are certain drawbacks to the direct use of forest biomass, such as low energy conversion rate and soot emissions and residues. Also, lack of continuous access to biomass is a severe concern in the long-term sustainability of direct electricity generation by forest biomass. To solve this problem, co-combustion with coal, as well as pelletizing of biomass, are recommended. The co-combustion of forest biomass and coal could reduce carbon monoxide, nitrogen oxides, and sulfide emissions of the process. Forest biomass can also be converted into various liquid and gaseous biofuels through biochemical and thermochemical processes, which are reviewed and discussed herein. Despite the favorable features of forest biomass conversion processes to bioenergy, their long-term sustainability should be more extensively scrutinized by future studies using advanced sustainability assessment tools such as life cycle assessment, exergy, etc.

“…Some alternatives considered to overcome this problem involve mixing with other low meltable ash biomass, fluidized bed operation, EFB pelletization, and/or a combination of the above. Pronobis correlated agglomeration to the mineralogical composition of the EFB, indicating that to enable the exploitation of the EFB at high temperatures it is necessary to remove alkaline and alkaline earth metals. ,− Erlich and Fransson pelletized EFB with moisture and mineral contents of 11 and 7.9 wt %, respectively, and evaluated the performance in a down-draft gasifier with air operating between 700 and 800 °C (ER between 0.23 and 0.43). They achieved cold efficiencies that varied between 38 and 63% and syngas yields between 1.8 and 2.5 Nm 3 /kg with HHV between 4.1 and 4.3 MJ/Nm 3 .…”

Wet-ground empty fruit bunches (EFBs), dry-ground EFB, and pelletized EFB were gasified in a laboratory-scale updraft fixed-bed reactor at differing temperatures and equivalent ratios (ERs) between 0.19 and 0.78 to evaluate the performance and quality of the syngas under autothermal operating conditions. In addition, the theoretical estimation of the key performance indicator of the ashes on the performance of the gasification process was obtained. The results show that for ERs > 0.4 the autothermal operating condition was achieved for pretreatments with pelletized and dry-ground EFBs, with reactor operating temperatures T > 700 °C. With wet EFB, this condition is achieved at any ER value. The average composition of the syngas from pelletized EFB presented the best average concentrations of the combustible species CO, H2, and CH4 when the ER values were between 0.25 and 0.40. The highest hot and cold thermal efficiency values were obtained for the gasification of EFB pellets with ER values between 0.25 and 0.40. For ground EFB, increases in the ER value led to improvements in hot thermal efficiency. Finally, during the EFB pellet gasification tests, no agglomeration and sintering problems were evidenced in comparison with wet-ground and dry-ground EFBs that showed slag formation, especially at ER < 0.46.

La agroindustria ecuatoriana representa un sector de participación importante para la economía. Su funcionamiento genera residuos que dada su composición y posibilidad de procesamiento, se convierte en un material de interés para ser aprovechado como materia prima en la elaboración de bioplásticos. La disponibilidad del residuo depende del volumen generado, razón por la cual se estimó la cantidad que produce la agroindustria del país, usando una metodología preestablecida que parte del promedio anual de cultivos, la porción de producción asignada al procesamiento industrial, la tasa de generación de residuos y otros usos competitivos. Se estimó que anualmente la agroindustria del país genera cerca de 2200 millones de kilogramos, los cuales en su mayoría están compuestos por almidón o recursos lignocelulosos, que con transformaciones físicas, químicas o biotecnológicas, pueden emplearse como materia prima, material de relleno o precursor de los bioplásticos.
