Abstract
Food wastes with high moisture and organic matter content are likely to emit odours as a result of the decomposition process. The management of odour from decomposing wastes is needed to sustain the interest of residents and local councils in the source separation of kitchen wastes. This study investigated the potential of baking soda (at 50Â g, 75Â g and 100Â g per kg food waste) to control odour from seven days stored food waste. It was found that 50Â g of baking soda, spread at the bottom of 8Â l food wastes bin, can reduce the odour by about 70%. A higher amount (above 100Â g) is not advised as a pH higher than 9.0 may be induced leading to the volatilization of odorous ammonia. This research finding is expected to benefit the waste management sector, food processing industries as well as the local authorities where malodour from waste storage is a pressing issue.
