dividing the extruded biodegradable material to form a plurality of biodegradable pellets;

applying a binding agent onto the plurality of biodegradable pellets; and

compressing the plurality of biodegradable pellets with the binding agent in a mold to form a biodegradable component corresponding to the geometry of the mold, wherein the binding agent is at a first temperature during the applying, and wherein the binding agent is cooled to a second, lower temperature prior to compressing such that the building agent freezes onto the plurality of biodegradable pellets.

2. The method of claim 1 , further comprising tumbling the plurality of biodegradable pellets to alter the shape of the plurality of biodegradable pellets prior to the applying the binding agent.

3. The method of claim 1 , further comprising tumbling the plurality of biodegradable pellets, wherein the tumbling includes heating the plurality of extruded biodegradable pellets to alter the surface of the plurality of extruded biodegradable pellets to include a sealing shell.

4. The method of claim 3 , wherein the tumbling shapes of the plurality of biodegradable pellets to have an elliptical profile.

5. The method of claim 1 , wherein the binding agent includes an aqueous material.

6. The method of claim 1 , wherein the binding agent includes dextrin.

7. The method of claim 1 , wherein the binding agent includes at least one of liquid soap, liquid glycerin soap, and solid glycerin bar soap.

8. The method of claim 1 , wherein the binding agent is a mixture consisting of water, a carbon-chain material, and a surfactant.

9. The method of claim 1 , further comprising compressing the plurality of biodegradable pellets in a plurality of molds disposed on a rotatable carousel, wherein the compressing includes compressing a first amount of the plurality of biodegradable pellets into a first mold of the plurality of molds, rotating a carousel to position a second mold of the plurality of molds to receive a second amount of the plurality of biodegradable pellets, and compressing the second amount of the plurality of biodegradable pellets into a second mold of the plurality of molds.

10. The method of claim 1 , further comprising adding an additive to the biodegradable material prior to extruding, wherein the additive includes at least one of latex, a blowing agent, and an adhesion promoter.

11. The method of claim 1 , further comprising dispensing a matrix material into the mold with the plurality of biodegradable pellets prior to the compressing.

12. The method of claim 1 , wherein the applying is performed in a chamber, wherein the plurality of biodegradable pellets are tack free before compression due to movement of the chamber causing movement of the plurality of biodegradable pellets during the applying.

13. A method of forming a biodegradable component, the method comprising:

extruding the biodegradable material through a die;

dividing the extruded biodegradable material to form a plurality of biodegradable pellets;

applying a binding agent onto the plurality of biodegradable pellets, wherein the plurality biodegradable pellets are at a temperature between 40 and 70° F. or at a temperature between 210° F. and 250° F. before applying;

compressing the plurality of biodegradable pellets with the binding agent in a mold to form a biodegradable component corresponding to the geometry of the mold, wherein the binding agent is at a first temperature during the applying, and wherein the binding agent is cooled to a second, lower temperature prior to compressing; and

melting a binding agent, wherein applying includes applying the melted binding agent on the plurality of biodegradable pellets.

14. The method of claim 13 , wherein the plurality of biodegradable pellets are heated to a temperature between 210° F. and 250° F. before applying.

15. The method of claim 1 , wherein the binding agent is applied to the plurality of biodegradable pellets by spraying in a spray chamber.

16. The method of claim 15 , wherein the plurality of biodegradable pellets remain separated during the spraying due to movement of the spray chamber.

17. The method of claim 1 , wherein the binding agent includes a first binding agent and a second binding agent, and one of the first and second binding agents is a dry particle.

18. The method of claim 1 , wherein the biodegradable material is dissolvable in water.

19. A method of forming a biodegradable component, the method comprising:

extruding the biodegradable material through a die;

dividing the extruded biodegradable material to form a plurality of biodegradable pellets;

applying a binding agent onto the plurality of biodegradable pellets; and

compressing the plurality of biodegradable pellets with the binding agent in a mold to form a biodegradable component corresponding to the geometry of the mold, wherein the binding agent is at a first temperature between 35° F. to 60° F. during the applying and the binding agent is cooled to a second, lower temperature prior to compressing; and

cooling the plurality of biodegradable pellets to a temperature at or below 0° F. prior to the applying.

20. The method of claim 13 , wherein the plurality of biodegradable pellets are at a temperature between 40° F. and 70° F. during the applying.
