Abstract
A biomass-derived thermosetting polymer material being a product of processing a biomass feed material via a twin screw extruder having a length extending between an inlet and an outlet. Hot water from a water heater is injected into at least one inlet along the length of the twin screw extruder, the at least one inlet generally corresponding with a pressure boundary within the twin screw extruder. A pressure-sustaining valve is connected between the length of the twin screw extruder and the outlet, with the valve being adjusted to produce the biomass-derived thermosetting polymer material.

A biomass-derived thermosetting polymer material comprising:
- a product of processing a biomass feed material via a twin screw extruder having a length extending between an inlet and an outlet and wherein:
- hot water from a water heater is injected into at least one inlet along the length of the twin screw extruder,
- the at least one inlet generally corresponds with a pressure boundary within the twin screw extruder;
- a pressure-sustaining valve connected between the length of the twin screw extruder and the outlet is adjusted to produce the biomass-derived thermosetting polymer material;
- and
- the twin screw extruder having single discharge outlet, the single discharge outlet downstream of the hot water inlet.
