Converts solid animal waste into bio‑oil via high‑temperature, high‑pressure oxygen‑free reforming for use as asphalt modifiers and agricultural coatings. Uses algae‑based wastewater treatment to remove nutrients (e.g., phosphorus to <0.05 mg/L) and provides farmers an affordable manure‑management solution that lowers carbon footprint while producing bio‑oil and algae usable as feed supplement, fertilizer, and energy.
