? 2022 Elsevier B.V.Reed is a promising biorenewable energy source given its ability to grow rapidly under environmentally challenging conditions. Pretreatment of reed by ball-milling in the presence of p-toluenesulfonic acid (p-TsOH) led to a significant reduction in hemicellulose (78%) and lignin (67%) content. After this pre-treatment, enzymatic hydrolysis of the residue led to a glucose content of 12.0 g/L. The enzymatic hydrolysis showed improved performance when ball-milling was included in the pre-treatment process. Both the residual lignin (extracted after pretreatment) and the solid residue (post enzymatic hydrolysis) were blended with polylactic acid (PLA) to prepare bio-based composites by injection molding, with the latter residue-plastic composite (RPC) possessing better mechanical properties. The bending strength, Young's modulus, bending modulus and impact strength of RPC were 29.08 MPa, 582.7 MPa, 879.4 MPa and 13.44 KJ/m2, respectively. The melting and crystallization temperatures of the composite were lower than that of pure PLA.
