"Biopellet" as One of Future Promising Biomassbased Renewable Energy: a Review

Abstract

The depletion of fossil energy reserves and not environmentally friendly fossil energy emissions makes it necessary to use renewable energy as an alternative to replacing fossil energy. Biopellet is one of the renewable energy based on biomass that exists in Indonesia. Biopellets are produced from a base of abundant biomass. Thus, biopellets have the potential and promise to continue to be used as fuel by humans. The literature review includes the characteristics of biopellets and the application of biopellets as fuel. Biopellets can be made by mixing biomass with an adhesive with a concentration of 15% (w/w) then stirred until homogeneous and put into a pellet mill for printing. The pellets were dried in an oven for 30 minutes. Biopellet characteristically has complied with SNI 8021-2014 for parameters of ash content, fixed carbon content, caloric value, water content, and volatile matter content. The application of biopellet as a stove material also shows good performance for heat, efficiency, and emission parameters. In conclusion, biopellet is a renewable energy fuel based on biomass that has potential in the present and promising in the future.

Fatty Acid Methyl Ester as an Additional Ingredient in Rice Husk Bio-Pellets to Improve Product Quality

“…Furthermore, the utilization of rice husks for ethanol manufacturing aids in the management of agricultural waste. The rice milling process typically yields 20-30% husk, 8-12% bran, and 50-63.5% milled rice, according to initial grain weight data (Wahyono et al, 2021). When rice is converted into bio-pellets, chemicals are added to increase fuel quality (Bow et al, 2022).…”

“…Still, over time, the availability of fossil energy is dwindling, and anticipating this new renewable energy is the best alternative (Putri et al, 2020) (Ploetz et al, 2016). So all energy sources must be controlled by the state and utilized and exploited optimally for the greatest prosperity of the Indonesian people to realize one of the ideals of the Indonesian people, namely to promote public welfare (Wahyono et al, 2021). Indonesia is an agricultural country where most of the population makes rice a staple food, and rice production is evenly distributed throughout the country (Bow et al, 2022).…”

Comparison Moisture of Biopellet from Sugarcane Bagasse and Coconut Dregs as Raw Materials for Co-Firing Power Plant

“…The increasing population growth in Indonesia greatly affects the amount of fuel energy used. In 2019, based on an inter-census population survey, Indonesia's population was projected to reach 266.91 million people (Wahyono et al, 2021). This becomes a problem for the government in meeting the need for gas fuel (Bow et al, 2022).…”

The influence of drying time on pellet fuel moisture content

“…Additionally, the continuous use of fossil energy can increase the occurrence of an energy crisis. Therefore, it is necessary to transition from fossil energy to alternative energy, one of which is the use of biodiesel, biomass, bio-pellets, biogas, and bio-briquettes [1]. According to the Indonesian Energy Outlook, land use in Indonesia produces 434,000 GW or equivalent to the production of 255 million barrels of oil per year.…”
