Abstract

Biochars and methods for treating biochars are provided that are useful in various applications, including, but not limited to, applications related to the raising, care, maintenance, disease prevention, disease treatment and odor control of animals.

First claim

We claim:

1. A method for incorporating an agent into bio-char for use in an animal application, the method comprising the steps of: treating biochar to clean the pores of the biochar of certain residual organic or inorganic compounds unsuitable for animal digestion, treating the biochar to introduce an agent into the pores of the biochar, where the agent introduced is beneficial for consumption by animals, and coating the biochar with a material to control the release of the agent.

2. The method of claim 1 where the agent is one or more of the following: a nutrient, a vitamin, a drug, a microbe, or a supplement.

3. The method of claim 1 where the residual organic or inorganic compound is a dioxin.

4. The method of claim 3 where the treated biochar has no detectible dioxins unsuitable for animal digestion.

5. The method of claim 1 where the treatment of the biochar also adjusts the pH of the biochar to be at a level beneficial for animal consumption.

6. A composition of matter, comprising: bio-char having outer surfaces and pores extending into the bio-char from the outer surfaces, the pores collectively having a total surface area; and an agent deposited within the pores to a depth of at least approximately 10-20 microns, where the agent is a microbe and where the biochar is coated with a material to control the release of the microbe.

7. The composition of claim 6 where the coating makes the surface of the biochar smoother than the surface without the coating.

8. The composition of the claim 6 where the coating is a starch.

9. A method for infusing biochar with microbes, the method comprising the steps of treating bio-char having outer surfaces and pores extending into the bio-char from the outer surfaces, the pores collectively having a total surface area, where treatment causes the deposit of an additive within the pores of the biochar to a depth of at least approximately 10-20 microns and where the additive is a microbe, and coating the biochar with a material to control the release of the microbe.

10. The method of claim 9 where the biochar is coated with a material that makes the surface of the biochar smoother than the surface of the biochar without the coating.

11. The composition of the claim 9 where the biochar is coated with a starch.

12. A biochar prepared for animal consumption, the biochar including an additive that is beneficial for animal consumption and promotes the health of the animal, the additive selected from the group consisting of: water, water solutions of salts, inorganic liquids of different polarities, organic liquids of different polarities, liquid organic compounds, combinations of organic compounds and solvents, vitamins, supplements, medications, nutrients, minerals, oils, amino acids, fatty acids, supercritical liquids, growth promotants, proteins, enzymes, phytogenics, carbohydrates, antimicrobial additives, sensory enhancers, microbial additives and bacteria; and where the biochar is coated with a material to control the release of the additive.

13. The biochar of claim 12 where the additive is infused in at least part of the pores of the biochar.

14. The biochar of claim 13 where the additive is infused into at least part of the pores of the biochar by placing the additive in a treating solution, adding the treating solution to a tank holding the biochar and by either pulling a vacuum on the tank or applying positive pressure on the contents of the tank.

15. The biochar of claim 13 where the additive is infused into the pores of the biochar by adding a surfactant to a liquid solution containing the additive and submerging the biochar in the liquid solution.

16. The biochar of claim 13 where the additive is infused into the pores by using ultrasonic treatment.

17. The biochar of claim 12 where the biochar has been treated to clean the pores of the biochar of certain residual organic or inorganic compounds unsuitable for animal digestion.
