New tech removes 98% fats, oils, and grease from kitchen waste that clogs sewers

Australian researchers have developed a wastewater treatment system that removes up to 98% of fats, oils, and grease from commercial kitchen wastewater, outperforming traditional interceptors. The design uses internal baffles and alum to separate and clump fat particles. This technology could prevent sewer-clogging "fatbergs," potentially saving water utilities billions in maintenance costs. The system can be retrofitted to existing setups and scaled for various kitchen sizes, offering a practical solution to prevent sewage spills.
