Anaerobic co-digestion of source segregated brown water (feces-without-urine) and food waste: For Singapore context

► Source separation of organic waste/wastewater streams on household level was done. ► Brown water (BW) was collected from a specially designed no-mix toilet. ► BW and food waste codigestion proved as a potential substrate for biogas production. ► A distinct improvement in methane yield was observed. ► This concept is vital for countries facing rapid urbanization and water shortage.
