Abstract

A method and system is provided for using biochar in composting environments to control temperature, moisture, acid and pH levels, odors and bacterial cultures. The method further includes treating the biochar prior to combining it with the compost to further control such parameters.

First claim

We claim:

1. A method for controlling composting parameters during the composting process, the method including the steps of providing composting material, adding treated biochar to the composting material to create a mixture and composting the mixture to create a compost.

2. The method of claim 1 wherein the treated biochar is inoculated with a thermotolerant endospore forming bacteria before adding it to the composting material.

3. The method of claim 1 wherein between 0.1-15% treated biochar on a volume basis is added to the composting material.

4. The method of claim 1 wherein between and 1-3% treated biochar on a volume basis is added to the composting material.

5. The method of claim 1 where raw biochars are also added to the composting material to create the mixture.

6. The method of claim 1 wherein the amount of added treated biochar is 0.1-15% by volume.

7. The method of claim 5 wherein the amount of raw and treated biochar added to the composting material together comprise 1-3% by volume of the mixture.

8. The method of claim 2 wherein the thermotolerant endospore forming bacteria is a Bacillus ssp. selected from the group consisting of: Bacillus licheniformis; Bacillus szutsauensis; Bacillus amyloliquefaciens; Bacillus subtilis; Bacillus velezensis ; and Bacillus pumilus.

9. The method of claim 1 wherein the treated biochar is treated by infusing a liquid into the pores of the biochar using positive or negative pressure.

10. The method of claim 1 wherein the treated biochar is treated by infusing liquid into the pores of the biochar using a surfactant.

11. The method of claim 1 wherein the treated biochar is treated by infusing liquid into the pores of the biochar using an ultrasonic treatment.

12. The method of claim 1 wherein the composting parameters are controlled by the addition of the treated biochar to the composting material and where the composting parameters controlled by the treated biochar are selected from the group consisting of: temperature, moisture, acid levels, pH levels, odors, air emissions, and microbial profiles.

13. The method of claim 12 wherein the air emissions are selected from the group consisting of: ammonia, volatile organic compounds, and methane.

14. The method of claim 1 wherein the treated biochar added to the composting material is biochar mixed with animal bedding.

15. The method of claim 1 wherein the treated biochar added to the composting material is a biochar solution.

16. A compost created from a composting process, the compost including a mixture of treated biochar and composting material, wherein the treated biochar comprises between 0.1-15% by volume of the compost.

17. The compost of claim 16 wherein the treated biochar comprises between 1-3% by volume of the compost.

18. The compost of claim 16 wherein the treated biochar is inoculated with a thermotolerant endo spore forming bacteria.

19. The compost of claim 16 wherein raw biochar is added to the treated biochar and where the raw and treated biochar together comprise between 1-3% of the compost.

20. The compost of claim 18 wherein the thermotolerant endo spore forming bacteria is Bacillus sp. selected from the group consisting of: Bacillus licheniformis; Bacillus szutsauensis; Bacillus amyloliquefaciens; Bacillus subtilis; Bacillus velezensis ; and Bacillus pumilus.

21. The compost of claim 16 wherein the treated biochar is treated by infusing a liquid into the pores of the biochar using positive or negative pressure.

22. The compost of claim 16 wherein the treated biochar is treated by infusing liquid into the pores of the biochar using a surfactant.

23. The compost of claim 16 wherein the treated biochar is treated by infusing liquid into the pores of the biochar using an ultrasonic treatment.

24. The compost of claim 16 wherein the composting material includes material selected from the group consisting of: wood, green waste, manure, animal bedding, agricultural waste, and food.
