Excessive food waste (FW) disposal in landfill can pose environmental such as greenhouse gas emission and leaching. Valorisation is a sustainable method that converts FW into value-added products such as soil amendment (compost), reducing FW in landfills and eliminates greenhouse gas emissions. FW contains high levels of nutrients such as C, N, P, K, Ca, and Mg, which are essential for plant growth. Valorisation of FW via composting and anaerobic digestion results in soil amendment products such as compost, liquid fertilizer. This study reveals the major research scopes needed to realise the value of these bio-products. The scopes include characterisation of their nutrient compositions from different biowaste, and the dilution rate or compost application rate. The overall strategies to realise the valorisation and the challenges will be discussed.
