Abstract
The Vortex–Acoustic Bio‑Refinery (VABR‑v2.0) is a conceptual modular system designed to convert municipal sewage sludge into biodiesel using vortex‑based solids concentration, tri‑band acoustic cavitation, dual‑stage heterogeneous catalysis, and high‑G centripetal coalescence separation. The system operates at near‑ambient pressure and is intended for decentralized deployment at wastewater treatment facilities. VABR‑v2.0 includes enhanced safety systems, catalyst‑recovery mechanisms, closed‑loop water reuse, and modular snap‑in
