Abstract
Systems and methods for recycling wet wipe, or wet plastic comprising, products are provided. The recycling process can include processing broken-down wet waste material into a molten polymer using a dewatering, degassing, and compacting extruder. The recycling process can also include dewatering, degassing, and compacting the broken-down wet waste material and the molten polymer being processed in the dewatering, degassing, and compacting extruder and removing gas and waste material residue from the dewatering, degassing, and compacting extruder and capturing large residue particles.
Claims36
An extruder system for recycling wet waste materials, the extruder system comprising:
- a main barrel comprising an inner chamber having a compressing and dewatering section and a heating, degassing, and compacting section following the compressing and dewatering section;
- an extruder screw comprising a dewatering, degassing and compression screw section and a discharge screw section, the dewatering, degassing and compression screw section of the extruder screw being configured to rotate within the inner chamber of the main barrel;
- a solid stage degassing port positioned on the main barrel and engaging the inner chamber of the main barrel to remove gas or vapor released by a molten polymer generated from a waste material being processed within the main barrel;
- a die positioned at an end of the main barrel, the die comprising one or more flow channels and configured to restrict a flow of material being processed in the main barrel and create backpressure and heat friction to help melt the material being processed into the molten polymer;
- a predischarge flow channel for receiving the molten polymer exiting the die, the predischarge flow channel configured for heating and degassing the molten polymer;
- and
- a discharge barrel connected to the predischarge flow channel, the discharge barrel comprising an inner chamber in which the discharge screw section of the extruder screw resides for receiving the molten polymer and a discharge port for discharging the molten polymer.

A recycling system for recycling wet wipe waste material, the recycling system comprising;
- one or more shredders for breaking down wet waste material being processed;
- a dewatering, degassing, and compacting extruder for receiving broken-down wet waste material from the one or more shredders, the dewatering, degassing, and compacting extruder configured to dewater, degas, and compact the wet waste material received from the one or more shredders to a molten polymer;
- and
- at least one solid stage degassing port on the dewatering, degassing, and compacting extruder to remove gas or vapor released by molten polymer generated from the wet waste material being processed in the dewatering, degassing, and compacting extruder.

A recycling process for recycling wet waste material, the recycling process comprising;
- breaking down wet waste material being processed with one or more shredders;
- processing broken-down wet waste material into a molten polymer using a dewatering, degassing, and compacting extruder;
- dewatering, degassing, and compacting the broken-down wet waste material and the molten polymer being processed in the dewatering, degassing, and compacting extruder;
- and
- removing gas and residue from the dewatering, degassing, and compacting extruder and capturing large residue particles from the residue.
