“…We believe, in daily practices, the real number of wood waste biomass should be higher than currently reported. Further, in line with our observation resultsof Soedirman and co-workers estimated the number of wood biomass produced from the logging activities in East Kalimantan was 7 to 1 ratio, where the number of logging waste biomass was 7m 3 for every cubic meter of wood harvested [1,2]. …”

“…Wood waste as well as residual woods are abundant withlignocellulosic materials that could be convertedto electricity by using several technologies available such as gasification, direct combustion and also steam processes. Nowadays, biomass energy conversion process was also known technically and economically feasible alternative to generating energy for production systems, even in remote locations where access to the electrical distribution network is not yet available [3]. Biomass-based energy also has several advantages such as wide availability and uniform distribution.…”

Abstract. In this work, the wood waste biomass from the logging activity of the natural forest area in East Kalimantan, Indonesia has been characterized in regards to the physicochemical properties and energy. The four species of wood waste biomass were Shorealeprosula (red meranti), Shoreabracteolata (white meranti), Shoreagibbosa (yellow meranti), and Shorealaevis (bangkirai). The total amount of wood waste biomass produced from the logging activity was 557.87 m 3 /plot(5.58 m3 ha -1 ). The waste biomass was identified as log end part (40.07%), bucking (27.39%), twigs (14.61%), stump (12.0%) and branch parts (5.92%), respectively. Among the four species studied, we observed that the highest volume of wood waste biomass was obtained from S. leprosulagiving 48.40% and followed by S. laevis 47.40%, and the last was S. bracteolata. From the field study, We noticed that the waste of wood biomass was not only yielded from the part of the log harvested such as branch, stump, log end and bucking processes but also reached from the damaged trees around the felling trees location and skidding operation. In general, the chemical composition of wood waste biomass studied was almost similar, while the highest calorivic value (HCV) was obtained from S. laeviswith value of 17.90 MJ/kg and followed by S. leprosula of17.38 MJ/kg, S. bracteolataof 17.09 MJ/kg, and S. gibbosa of 16.86 MJ/kg.The logging wood waste biomass was estimated sufficient to provide and supply 3668.62 GJ energy, to generate ±1,019 MWh electricity that equivalent to ±10.19 MWh electricity potency per hectare.

Thermal characterization of coffee husk (Coffea arabica) from Colombian coffee has been studied. Different products, mostly volatile and semi-volatile compounds, were analyzed paying special attention to 16 polycyclic aromatic hydrocarbon classified by Environmental Protection Agency (EPA) as priority pollutants, frequently used for checking toxicity in environmental samples. Fixed amount of raw material was

“…Coffee husk (CH) is a by-product from coffee seed shelling; for example, 100 kg of coffee seed produces about 86 kg of green coffee and 14 kg of CH [5], which leads to a production of about 138697 tons of CH per year in Colombia. In Colombia, many coffee agroindustries do not have the appropriate CH, waste handling infrastructure, which could result in the pollution of natural sources [6]. Using CH wastes as feedstock for locally placed gasification can reduce both the pollution generated by coffee industries and the dependence of these industries on fossil fuels.…”

The increasing energy consumption, mostly supplied by fossil fuels, has motivated the research and development of alternative fuel technologies to decrease the humanity's dependence on fossil fuels, which leads to pollution of natural sources. Small-scale biomass gasification, using air-steam blends for partial oxidation, is a good alternative since biomass is a neutral carbon feedstock for sustainable energy generation. This research presents results obtained from an experimental study on coffee husk (CH) gasification, using air-steam blends for partial oxidation in a 10 kW fixed-bed gasifier. Parametric studies on equivalence ratio (ER) (1.53 < ER < 6.11) and steam-fuel (SF) ratio (0.23 < SF < 0.89) were carried out. The results show that increasing both SF and ER results in a syngas rich in CH 4 and H 2 but poor in CO. Also, decreased SF and ER decrease the peak temperature ( peak ) at the gasifier combustion zone. The syngas high heating value (HHV) ranged from 3112 kJ/SATPm 3 to 5085 kJ/SATPm 3 and its maximum value was obtained at SF = 0.87 and ER = 4.09. The dry basis molar concentrations of the species, produced under those operating conditions (1.53 < ER < 6.11 and 0.23 < SF < 0.89), were between 1.12 and 4.1% for CH 4 , between 7.77 and 13.49% for CO, and between 7.54 and 19.07% for H 2 . Other species were in trace amount.
