Abstract
Systems and methods are provided for converting organic waste materials from a municipal waste stream to useful products. Organic waste materials having a wide range of compositions such as, for example, yard waste, food waste, paper, and the organic fraction of municipal solid waste are converted into a uniform biomass that is suitable for conversion to useful products, such as fuels. Through the use of a biomixer and a hydropulper, as well as through sorting and screening, the organic waste materials are progressively reduced in size and cleaned of contamination. The resulting uniform biomass is suitable for anaerobic digestion to produce biogas and a residual solid that is suitable for producing a high quality compost.
Claims (21)
1. A system for converting organic waste materials, comprising:
a biomixer configured to convert a first portion of the organic waste materials into a partially hydrolyzed biomass;
a first screening apparatus, including a screen mesh, and configured to screen the partially hydrolyzed biomass into unders that pass through the screen mesh;
a hydropulper configured to receive the unders from the first screening apparatus and to create a slurry therefrom; and a hydrocyclone configured to remove grit from the slurry.
a biomixer configured to convert a first portion of the organic waste materials into a partially hydrolyzed biomass;
a first screening apparatus, including a screen mesh, and configured to screen the partially hydrolyzed biomass into unders that pass through the screen mesh;
a hydropulper configured to receive the unders from the first screening apparatus and to create a slurry therefrom; and a hydrocyclone configured to remove grit from the slurry.
2. The system of claim 1 wherein the first screening apparatus includes a trommel.
3. The system of claim 1 further comprising a second screening apparatus, including a screen mesh, and configured to screen a second portion of the organic waste materials into unders that pass through the screen mesh and overs that do not, wherein the hydropulper is configured to also receive the unders from the second screening apparatus.
4. The system of claim 3 wherein the second screening apparatus includes a trommel.
5. The system of claim 3 further comprising a grinder configured to grind the unders from the second screening apparatus, wherein the hydropulper is configured to receive the ground unders.
6. The system of claim 1 further comprising a sorting facility configured to remove undesirable materials from the organic waste materials.
7. The system of claim 6 wherein the sorting facility includes a sorting floor.
8. The system of claim 6, wherein the sorting facility includes a sorting line.
9. The system of claim 1 further comprising an anaerobic digester configured to receive the slurry.
10. The system of claim 9 further comprising a compost facility configured to receive residual solids from the anaerobic digester.
11. A method for converting organic waste materials, comprising:
processing a first portion of the organic waste materials in a biomixer to create a partially hydrolyzed biomass;
screening the partially hydrolyzed biomass into unders that pass through a first screen mesh;
hydropulping the unders to remove heavier and lighter materials and to create a slurry of the remainder; and removing grit from the slurry.
processing a first portion of the organic waste materials in a biomixer to create a partially hydrolyzed biomass;
screening the partially hydrolyzed biomass into unders that pass through a first screen mesh;
hydropulping the unders to remove heavier and lighter materials and to create a slurry of the remainder; and removing grit from the slurry.
12. The method of claim 11 further comprising screening a second portion of the organic waste materials into unders that pass through a second screen mesh and overs that do not pass through the second screen mesh, wherein the unders from the second portion of the organic waste materials are hydropulped with the unders from the partially hydrolyzed biomass to create the slurry.
13. The method of claim 12 further comprising processing the overs with the first portion of the organic waste materials in the biomixer.
14. The method of claim 12 further comprising grinding the unders from the second portion of the organic waste materials prior to hydropulping.
15. The method of claim 11 further comprising sorting the organic waste materials prior to processing the first portion of the organic waste materials in the biomixer.
16. The method of claim 11 further comprising anaerobically digesting the slurry to produce biogas and a residual solid.
17. The method of claim 16 further comprising dewatering the residual solid and composting the dewatered residual solid.
18. The method of claim 17 further comprising recycling water from dewatering the residual solid back to hydropulping.
19. The method of claim 11 wherein the organic waste materials include source separated organic waste materials.
20. The method of claim 11 wherein the organic waste materials include municipal solid waste.
