Abstract
A method and apparatus to process a diverted molten polymer waste stream directs the polymer stream to one of at least two passages, separates it into individual segments while containing and discharging it from a containment exit, cools each segment with a quench fluid to form a solid or semi-solid polymer, and transports the solidified segments away from the exit and into a container using the quench fluid. The apparatus includes a cross-section transition connector, a moveable block with two passages, a block oscillator, a cut-off plate, and open space above an inclined transporting device, a quench fluid jet, and a quench fluid transporting trough.
