Treatment of domestic waste is generally carried out by activated sludge process. The waste solid sludge can be treated by various aerobic and anaerobic treatment processes. Aerobic treatment methods need space and time. Anaerobic treatments have advantages such as space utilization and production of fuel gases such as methane. Up flow anaerobic sludge digester or fluidized bed digester can be used for anaerobic treatment. Vermi-composting of domestic sludge is also practically feasible and economical alternative. The waste food is sizeable part of domestic sludge. This waste food can be used as a feedstock for synthesis of ethanol like compounds. Current review summarizes investigations and literature studies carried out on utilization of waste food for various applications
