In the present research, an attempt has been made to develop a pelletizing process to improve the properties of biomass pellets, as many of the important properties of the pellets are dependent upon the raw and additives materials. Thus, their proper selection has a vital role in producing better quality pellets. The information about the material properties of raw materials, such as rice husk and sawdust, as well as their effect over the quality of the manufactured pellets were studied. The thermochemical properties of various rice husks have been analyzed to improve the decision to select better quality raw materials for the pelletizing process. The chemical composition of three other biomass raw materials (namely beech, spruce, and straw) has also been analyzed to prove that the presence of hydrophobic extractives has a significant influence on the bonding quality between biomass particles during the pelletizing process. Therefore, choosing a less extractive raw material is beneficial for the pelletizing process. After analyzing the thermochemical properties of various rice husks, ROK 14 and BRRI 46 were found better for pellets production. The beech type of raw materials was found to be more suitable for its adhesive bonding ability during pelletization. The present study also discusses the properties of various starch as additives and their effect on the production of pellet characteristics, and the Oxidized Corn starch was found to be the best additive, in the peasant research, as it not only improves properties but also reduces power consumption.

the world. Agricultural residues can play a vital role as a source of renewable energy to
overcome the crisis. Rice husk is the second-largest agricultural residue in Bangladesh and
uses significantly for cooking conventionally in rural areas. The traditional method greatly
decreases the rice husk’s ability for heating. The use of rice husk as pellets greatly reduces
the loss of energy during use, thereby enhancing its efficiency. The purpose of this research
is to develop an efficient process to produce biomass pellets using rice husk. The objective of
this study can be accomplished by finding better rice husk and suitable additives for pellet
processing. It is possible to find better rice husk by studying its thermochemical properties.
By using various additives for pelletizing, examining the pellets to evaluate their different
properties, and comparing those properties, suitable additives can be obtained. The BRRI
Dhan 46 rice husks were classified as the most suitable candidate for Bangladesh. Rice flour,
Banana Peel, Potato peel, and Cornflour were used as additives during pelletizing. Wet
papers were used at a certain ratio with rice flour, and cornflour to judge its effect on the
production of pellets. Small rice husk particles and blended wet papers have shown major
advantages during pelletization and have improved the pellet properties significantly. To
assess the quality of the pellets, length, weight, bulk density, pellet formation time, and
flame period were measured. Among all starch additives used in this research, Rice flour
was found to be the finest. 3:1:1:1 ratio of rice husk, rice flour, tissue paper, and water were
maintained during pelletizing while using rice flour as additives. Our findings in this research
may help the small-scale pellet industries in the rural areas in Bangladesh for the production
of better quality rice husk pellet and may encourage the consumers to show interest in the
proper use of biomass energy.
