Process for forming a product solution from poultry waste digestate
11053173 · 2021-07-06 · ·

Disclosed are methods and systems for the conversion of poultry waste into useful products. Some embodiments are directed to a process for forming a product solution from poultry waste. The process includes providing a feedstock that contains greater than 60 percent poultry waste, and anaerobically digesting the feedstock to produce a digestate that has a solids content of about 5% to about 15% by weight. The process also includes separating and classifying the digestate into multiple high solids fractions and a first filtrate. The process also includes adding the high solids fractions to an acid solution to form a slurry that is then separated and classified into multiple second solids fractions and a second filtrate. The process also includes clarifying the first and second filtrates to produce a first and a second centrate. The process also includes mixing the first centrate with the second centrate to form the product solution.

SYSTEM AND METHOD FOR VERTICALLY-ORIENTED COMPOSTING
20240246129 · 2024-07-25 ·

A system and method for vertically-oriented, modular, automated, emissions-controlled composting. In an embodiment, the system and method involve construction of a vertically-oriented set of composting modules comprising a receiving and offloading level, one or more composting bay levels, a feedstock staging level, a biofilter level, a vertical conveyor for uploading feedstock to the feedstock staging level, a freight and personnel elevator, and a leachate tank. This composting system and method reduces the land area required for composting, increases the capture of emissions from composting, and reduces the labor-intensive and heavy-equipment-intensive nature of current methods.
