Dataset of biopellet characteristics from various lignocellulosic agricultural waste and shrubs produced using different method

Abstract

The data presented here is the characteristics of biopellets and its raw materials. The raw materials of lignocellulosic waste (coffee skin, corncob, patchouli waste) and shrubs (<i>Leucaena leucocephala</i> and <i>Gliricidia sepium</i>) were collected from certain districts in Indonesia which provided quite abundant stocks of these raw materials. The raw material preparation and pelletization at room temperature (25 °C) using a manual press machine were carried out at Hasanuddin University, Makassar, Indonesia. Meanwhile, pelletization at high temperatures (225 °C) was carried out at The Integrated Laboratory of Forest Research and Development, Bogor, Indonesia. The evaluation of density, moisture content, volatile matter content, ash content, and amount of fixed carbon were also carried out at the laboratory. Meanwhile, evaluation of mineral content (sulfur, Na₂O, K₂O, Cl) and calorivic value was carried out at the Livestock Research Institute, Bogor, Indonesia. The results show that pelletization at high temperature produces better quality biopellets compared to pelletization at room temperature. Pelletization of L. <i>leucocephala</i> at high temperature produces the best quality biopellets with the highest density (1.17 g/cm³) and calorific value (4726 kcal/kg) and the lowest moisture content (4.87 %) and mineral content (0.01 % of S, 0.0014 % of Na₂O, 1.53 % of K₂O, and 0.17 % of Cl) among the other raw materials tested. This dataset is expected to be a primary source in comparing and determining the proper type of raw material for biopellet production as an alternative renewable energy source, especially those originating from shrubs and similar lignocellulosic waste.
