Torrefaction is a thermal treatment method used to achieve solid-phase biofuel. Raw biomass generally have low heating value and high moisture content; thus, these characteristics should be enhanced before using it as a fuel. In this study, herbaceou

Bottom ash generated by the combustion of cattle manure (BA-CCM) was investigated as an adsorbent for the removal of heavy metals such as Cd(II), Cu(II), Pb(II), and Ni(II) from aqueous solutions. When cattle manure was used as fuel, the thermal effi

Ethanol organosolv (EO) fractionation is a promising technology for producing high-purity lignin from kenaf, a lignocellulosic biomass. However, EO fractionation could not be used for the hemicellulose fraction because of the removal of hemicellulose
