“…The use of wood with high basic density culminates in charcoal with a higher bulk density and better mechanical resistance, which is desirable for the steel industry (Vieira et al 2019). Denser woods also have a higher energy density, which is the energy stored in a given volume of wood (Simetti et al 2018).…”

The study investigated the intra-stem and inter-stem variations of wood basic density in Tachigali vulgaris, influenced by different planting spacing and the occurrence of forking in a trial carried out in Pará State, Brazil. The experiment was performed in a randomised block design, arranged in a split-plot scheme, where plot effect was constituted by planting spacing (4.5, 6.0, 7.5, 9.0, 10.5 and 12.0 m2) and forking, as the effect of subplot (forked or not forked). The wood basic density increased from narrower to wider planting spacings. The wood basic densities in planting spacings of 9 m² (0.517 g cm-3) and 12 m² (0.529 g cm-3) were 16.9 and 19.4% higher compared to the lowest planting spacing of 4.5 m2 (< 0.500 g cm-3). Forking reduced wood density by almost 7% and promoted a wider variation within the stem. Forked stems decreased basic density towards the base-top direction. The findings suggested that, 87-months-old wood of T. vulgaris is suitable for energy purposes, and recommended for the establishment of homogeneous plantations in Brazilian Amazonia.

“…Previous researchers have used biomass as an alternative source of energy, including rice husk, cider mumps, sawdust, coconut shells, wood chips, sago pith waste, forest waste and so on (Petabang, 2012;Fretes et al, 2013;Muhammad et al, 2013;Karim et al, 2014;Oladeji, 2016;Suhartoyo and Sriyanto, 2017;Marafon et al, 2019;Vieira et al, 2019;Saghir et al, 2019). In this study, biomass used was animal waste namely cattle waste from Lembang-West Java.…”

Aim: This paper aims to explain the added value increasing method of reject coal which has not utilized by the company. Methodology and Results: The method to increase added value in this study used the agglomeration process of briquettes form that changing composition by adding biomass. The biomass functions to minimize bottom ash produced from burning briquettes so that the briquettes burn entirely. Stages processes in this study consist of characterization, briquetting, physical test, and chemical test. Based on the analysis, reject coal still has a high calorific value of 5,929 cal/gr. Shapes and sizes that were not following needs of coal market or consumer due to reject coal to be a waste. Briquettes have been successfully produced and meet specification requirements based on applicable regulations in Indonesia. Besides physical properties, the briquette meet density requirements which are greater than or equal to 1 gr/cm3 and shatter index value is less than 0.5%. The gas emission test shows below threshold, which is CO 0-30 ppm, H2S 0-3.6 ppm, and NOx is not detected. After evaluation, it showed that by adding 30% biomass, ignition time could be decreased and remaining unburned briquettes or bottom ash was reduced as much as 68.68%. Conclusion, significance and impact study: The bio-coal briquettes is a strategic solution to environmental problems and alternative energy sources that are environmentally friendly, because CO and H2S emissions are still below the threshold, even for NOx not detected. Making Bio-coal briquettes as a solution to the utilization of reject coal mining waste to be used as an alternative energy source has been successfully carried out.

Forestry Biomass as Energy Source in Brazil

Abstract: In the world context, concerning the raw materials used as biomass supply sources, firewood predominates as a source of energy, followed by wood derivatives, such as charcoal and forest residues [10]. However, in Brazil, the use of sugarcane
