Food waste was ﬁrst ultra-fast hydrolyzed by fungal mash rich in Fungal mash hydrolytic enzymes in-situ produced from food waste. After which, the separated solids were readily converted Microbial fuel cells to biofertilizer, while the liquid was fed to MFCs for direct electricity generation with a conversion eﬃciency of Electricity 0.245 kWh/kg food waste. It was estimated that about 192.5 million kWh of electricity could be produced from Biofertilize the food waste annually generated in Singapore, together with 74,390 tonnes of dry biofertilizer.
