Abstract Heterogeneous briquettes formulated from abundant rice husk and pine sawdust blended and treated with HCl can address limited access to clean energy. However, briquettes from untreated blends of rice husk and pine sawdust exhibit higher ash content, which reduces their thermochemical characteristics.

Abstract Heterogeneous briquettes made from rice husk-pine sawdust blend treated with sulfuric acid have the potential to satisfy the increasing global demand for sustainable energy. However, untreated blends are constrained by unfavorable thermochemical properties. In this study, a blend comprising 10 wt% rice husk and 90 wt% pine sawdust was subjected to H2SO4 treatment at 1%, 2%, 3%, 4%, and 5% (v/v) for 1-h at ambient temperature.
