Large quantities of spent coffee grounds (SCGs) are produced daily across the globe, accumulating as industrial waste in factories. Developing a process that both extracts high-value components and utilizes bulk material would offer significant academic advantages. This study explores use hydrodynamic cavitation, which chemical physical effects by bubble collapse, for high-efficiency, continuous processing. The optimization cavitation conditions was conducted measuring aggressive intensity within Venturi tube. Then, unbrewed processed to obtain stable results, caffeic acid SCGs varied depending on how brewed. It revealed tube increased extraction rate coffeic simultaneously generates cellulose microfibrils. Note upstream pressure 3.4 MPa, generated screw pump, enhanced optimizing downstream type closely linked intensity, also analyzed through high-speed photography.
