1. A method for producing biobased carriers for dispersal of biological and chemical molecules, the method comprising: providing an apparatus for producing biobased carriers, the apparatus including a premixer, a shear mixer, an agglomerator, and a power source for controlling an operation of the apparatus, the shear mixer having a cylindrical housing and a shear mechanism within the housing, the housing defining an inner surface and an opening, the shear mechanism comprising a screen covering the opening, a stationary stator, and a rotatable rotor disposed within the stator, the rotor comprising a shaft and a plurality of rubbing bars mounted and radially spaced around the shaft to rotate with the shaft, wherein each of the rubbing bars has an arcuate outer surface operable to move in a circumferential direction along an inner surface of the screen when the shaft rotates, wherein at least a portion of each respective arcuate outer surface defines a plurality of elements extending up or down from the respective arcuate outer surface to enhance shear created between the plurality of rubbing bars, the screen, and the inner surface of the stator;adding a wet biomass processing coproduct and a binder into the premixer;mixing the coproduct and the binder in the premixer to form a paste;shear mixing the paste in the shear mixer by rotating the shaft thereof to create flow and shear between the plurality of rubbing bars, the screen, and the inner surface of the housing, force the paste along the screen in the circumferential direction thereof, and force and extrude the paste through the screen and out of the housing in the form of particles that are sufficiently broken down at the screen to pass through the screen; andagglomerating the particles with the agglomerator to form spherical biomass pellets. 2. The method of claim 1, wherein the providing step includes the shear mixer having drive means within the housing for receiving the paste from the premixer and forcing the paste into the shear mechanism. 3. The method of claim 1, wherein the providing step includes the screen having a mesh size between about 3 mm and 4.5 mm. 4. The method of claim 1, wherein the providing step includes the screen having a mesh size about 3.2 mm. 5. The method of claim 1, wherein the providing step includes the screen extending about 120 degrees about the housing. 6. The method of claim 1, wherein the providing step includes the stator comprising the inner surface of the housing. 7. The method of claim 1, wherein the providing step includes the plurality of rubbing bars having the outer surfaces spaced about 4 mm and 10 mm from the stator. 8. The method of claim 1, wherein the providing step includes the stator of the shear mechanism comprising the screen. 9. The method of claim 1, wherein the providing step includes the agglomerator being a rotary drum dryer having an interior chamber. 10. The method of claim 9, wherein the providing step includes the rotary drum dryer having lifters extending inwardly in the interior chamber. 11. The method of claim 1, wherein the adding step includes the wet biomass processing coproduct being wet distillers grain. 12. The method of claim 1, wherein the adding step includes the wet biomass processing coproduct having between about a 50% to 70% moisture content. 13. The method of claim 1, wherein the adding step includes the binder comprising at least one of condensed distillers solubles, thin stillage, glycerol and polymer. 14. The method of claim 13, wherein the adding step includes the binder being condensed distillers solubles. 15. The method of claim 14, wherein the providing step includes the apparatus further including heating means for heating the condensed distillers solubles before the condensed distillers solubles are added to the premixer. 16. The method of claim 1, wherein the adding step includes adding at least one of a dry feedstock, polymer and biomass to the premixer to lower a moisture content of the wet biomass processing coproduct to between about a 50-70% moisture content. 17. The method of claim 13, wherein the adding step includes adding at least one of a chemical agent and a biological agent. 18. The method of claim 17, wherein the adding step includes the at least one of the chemical agent or the biological agent being at least one of an enzyme, pesticide, herbicide, fungicide, rodent bait poison, animal vaccination, animal medication, animal supplement, and nutrients. 19. The method of claim 1, wherein the shear mixing step includes the particles having a diameter in the range of between about 300 to 500 microns. 20. The method of claim 1, wherein the adding step includes the binder being a liquid other than water.
