Researchers heated sewage sludge at 325C for 30 minutes before centrifugation; the process converted 88% of the sludge and recovered bio-oil at up to 64%

Researchers have pioneered an innovative method that transforms sewage sludge into valuable bio-oil using hydrothermal liquefaction techniques applied at optimized temperatures and pressures. A notable advancement in this process is the centrifugation step prior to filtration, enhancing oil recovery efficiency. This sustainable approach presents a promising alternative to conventional waste management strategies and has the potential to be seamlessly incorporated into existing fuel supply systems.
