Abstract
The present invention is directed to a substantially odorless biological treatment process for solid and liquid organic wastes. The present invention also provides for a novel nutrient rich humus material produced from the biological treatment process. The bioconversion process of the present invention results from low oxygen concentrations and high quantities of microorganisms in a diverse microbial community.
Claims28
A method for converting organic waste into a beneficial humus material comprising:
- combining organic waste with a liquid thereby creating a waste stream;
- treating said waste stream in an aqueous environment containing about 1015 or more biological microorganisms with an average doubling time of less than about 30 days;
- adding oxygen sufficient to maintain less than about 2.0 mg/l of dissolved oxygen in said aqueous environment, and
- separating solids from said aqueous environment for the recovery of an organic humus material;
- wherein, the waste stream is simultaneously nitrified and denitrified.

A method for converting organic waste into a beneficial humus material comprising:
- combining organic waste with a liquid thereby creating a waste stream;
- treating said waste stream in an aqueous environment containing biological microorganisms regenerating at a rate of more than about 105 base pair replications per second;
- adding oxygen sufficient to maintain less than about 2.0 mg/l of dissolved oxygen in said aqueous environment;
- and
- separating solids from said aqueous environment for the recovery of an organic humus material;
- wherein, the waste stream is simultaneously nitrified and denitrified.
