Abstract

A Biorefinery System (BIOSYS) that effectively treats all human activity-derived waste (black water, grey water, and food waste streams) using biological systems and that produces as process by-products: recovered potable water, liberated free oxygen, edible protein cake (with and without lipids), soil amendments, and machinery lube oils. Additionally, the system captures and chemically binds carbon dioxide into microbial cells and associated by-products, thus producing recovered usable returned cabin air.

Claims8

Dependent claims

An influent biorefinery method comprising the steps of:

a. anaerobically digesting an influent to produce effluents comprising simple organic acids and residual soluble chemical oxygen demand;
b. processing said simple organic acids and said soluble chemical oxygen demand to produce lipid and protein enriched microbial solids;
c. extracting said lipids from at least a portion of said lipid and protein enriched microbial solids to produce at least one value-added product;
d. reacting at least a portion of said lipid and protein enriched microbial solids to produce a second at least one value-added product and an aqueous effluent;
and
e. adsorption polishing said aqueous effluent to produce a third at least one value-added product.
