Abstract: A composite material may be prepared from a solid polymeric binder and a solid filler by feeding into an extruder the solid polymeric binder at a first feed rate and the solid filler at a second feed rate. The extruder extrudes an extrudate of the solid polymeric binder and solid filler to form the composite material. The composite material has a binder to filler ratio determined by the first feed rate and second feed rate. The solid polymeric binder and solid filler have different densities. Feeding the solid polymeric binder at the first feed rate and the solid filler at the second feed rate distributes the solid filler substantially homogeneously throughout the composite material.

Abstract: A method for processing polyester-cotton blend textile waste includes adding polyester-cotton blend textile waste to a rotating drum of a rotary hydrolysis reactor. Water and a base are added to the rotary hydrolysis reactor and heated. The polyester-cotton blend textile waste is agitated with a plurality of ribs by rotating the inner drum relative to a housing of the rotary hydrolysis reactor to enable the hydrolysis of PET into a TPA and ethylene glycol solution with solid reclaimed cotton free of PET. The TPA and ethylene glycol solution is separated from the solid reclaimed cotton and directed to a hydrolysate recovery vessel. In the hydrolysate recovery vessel the TPA is precipitated and separated from the remaining liquid and the ethylene glycol is then recovered.
