Valorization of Pennisetum setaceum: From Invasive Plant to Fiber Reinforcement of Injected Composites.

ABSTRACT: During the control campaigns of Pennisetum setaceum (invasive species widespread worldwide), the generated waste has accumulated in landfills. This study investigates its use to obtain P. setaceum fibers for their application as reinforcement of polymeric materials for injection molding, thus facilitating and promoting alternatives for the long-term sustainable management of P. setaceum. The extracted fibers were treated with alkaline, silane, acetic acid, and combined alkaline and silane treatments. Different composites with 20 and 40 wt% of fiber were extruded, and test samples were obtained by injection molding using recycled polyethylene as matrix. The composition of the fibers was determined by gravimetric methods, and contrasted with the analysis of the functiona
