Method & Evidence

AimTo investigate the feasibility and effectiveness of pyrolyzing fiberglass-reinforced polyester composite scraps for the recovery of usable materials and energy.

MethodExperimental analysis

ProcedureComposite scraps were subjected to pyrolysis at varying temperatures (500, 550, and 600°C). The resulting oil, gas, and solid residue fractions were analyzed. The solid residue (glass fibers) underwent a subsequent oxidative process to remove residual organic matter, and the properties of the recovered glass fibers were evaluated.
