Abstract The increasing demand for renewable energy sources has driven the exploration of innovative materials for biofuel production. This study investigates bio-pellet characteristics derived from several oyster mushroom baglog wastes with varying concentrations of molasses as an adhesive. The process began with sun-drying the baglog waste for three days, followed by oven drying at 80°C for 24 h. Bio-pellets were produced by blending baglog waste with molasses at concentrations of 5% and 10% (w/v), then subsequently fed into a pellet mill. The bio-pellets were left to rest for one hour before analysis. The quality of bio-pellets… More > Graphic Abstract

Abstract The increased valorization of renewable and cost-effective lignocellulosic feedstocks represents a viable, sustainable, and eco-friendly approach toward the production of biopellets as alternative energy sources. The aim of this research work was to investigate and evaluate the feasibility of using various lignocellulosic raw materials, i.e., raru (Cotylelobium melanoxylon), mangrove (Rhizophora spp.), sengon (Paraserianthes falcataria), kemenyan toba (Styrax sumatrana), oil palm (Elaeis guineensis), manau rattan (Calamus manan), and belangke bamboo (Gigantochloa pruriens) for manufacturing biopellets with different particle sizes. The raw materials used were tested for their moisture content, specific gravity, ash, cellulose, and lignin content. In addition, thermal analyses, i.e., calorific values,… More >
