GEORGE TOWN: For the past two months, Brandon Wee Hong Jie has been dutifully collecting leftover food and waste from the eight stalls at the Heng Ee High School canteen.
The 16-year-old then carries the buckets of waste – including noodles, rice, fruit peels, vegetables and small pieces of bones – to a machine next to the canteen, adds bokashi fermentation microbes and bio-cleaners and starts grinding the mixture.
