Abstract

A method for capturing material extracted from biochar, the method comprising the steps of: (i) providing a biochar; (ii) contacting the biochar with a treating liquid, where the treating liquid causes the removal of solids from the pores and surface of the biochar, thereby creating a resulting solution or extract comprised of the treating liquid and removed solids; and (iii) collecting the resulting solution or extract. The method further comprises the step of apply the resulting solution or extract to soil or for use in other applications.

Claims

1. A method for capturing material extracted from biochar, the method comprising the steps of:

providing a biochar that includes residual organic compounds;

contacting the biochar with a treating liquid, wherein the treating liquid removes at least some of the residual organic compounds from the biochar, thereby creating a biochar extract containing residual organic compounds;

collecting the biochar extract; and

filtering the biochar extract.

2. The method of claim 1 wherein the biochar extract is collected from centrifuge effluent.

3. The method of claim 1 wherein the biochar extract is created by infusing liquid into the pores of the biochar and then removing at least part of the infused liquid from the pores of the biochar.

4. The method of claim 1 wherein the treating liquid is water.

5. The method of claim 1 wherein contacting the biochar with a treating liquid comprises:

introducing the biochar to a chamber;

adding the treating liquid to the chamber; and

changing the pressure in the chamber to infuse the treating liquid into the pores of the biochar.

6. The method of claim 1 wherein collecting the biochar extract includes the step of extracting at least some of the treating liquid from the pores of the biochar.

7. The method of claim 6 wherein the treated liquid is extracted using a centrifuge.

8. The method of claim 1 further including the step of applying the biochar extract to soil.

9. The method of claim 1 where filtering the biochar extract includes the removal of larger biochar particles from biochar extract.

10. A method for capturing material extracted from biochar, the method comprising the steps of:

providing a biochar that includes residual organic compounds;

contacting the biochar with a treating liquid, wherein the treating liquid removes at least some of the residual organic compounds from the biochar, thereby creating a biochar extract containing residual organic compounds;

collecting the biochar extract, where the step of collecting the biochar extract includes collecting the extract from a centrifuge effluent.

11. The method of claim 10 wherein the treating liquid is water.

12. The method of claim 10 wherein the residual organic compounds comprise volatile organic compounds.

13. A method for creating a biochar extract, the method comprising the steps of:

introducing the biochar to a chamber;

adding the treating liquid to the chamber; and

changing the pressure in the chamber to infuse the treating liquid into the pores of the biochar;

extracting at least some of the treating liquid from the pores of the biochar;

collecting the extracted liquid; and

applying the extracted liquid to soil.

14. The method of claim 13 where the treating liquid is added to the chamber before the pressure in the chamber is changed.

15. The method of claim 13 where the treating liquid is added to the chamber while the pressure in the chamber is changed.

16. The method of claim 13 where the pressure is changed in the chamber by either pulling a vacuum on the chamber or applying positive pressure on the content of the chamber.

17. A method for capturing material extracted from biochar, the method comprising the steps of:

introducing the biochar to a chamber;

adding the treating liquid to the chamber; and

changing the pressure in the chamber to infuse the treating liquid into the pores of the biochar;

extracting at least some of the treating liquid from the pores of the biochar using a centrifuge; and

collecting the extracted treating liquid; and

filtering the extracted treating liquid.
