From 2000 to 2017, the global urban population has increased from 2.9 billion to 4.1 billion and by 2030, it is expected to reach 5.1billion out of 8.6 billion of global population [1]. The explosion of population and increment of urbanization with changing lifestyles create more and more wastes are being generated in many cities and townships. This ever-rising shift of the world population is already evident and will produce even more remarkable amounts of urban food waste, which in turn will add pressure to the already overloaded municipal solid waste transportation system and landfill sites [2]. According to the study conducted by SWCorp showed that Malaysians generated 38,000 tonnes of solid waste daily in 2016, of which 15,000 tonnes was food waste. It found that 20%, or 3,000 tonnes, of this food waste was avoidable [3]. Most food waste has been land filled together with other wastes, resulting in various problems such as emanating odor, attracting vermin, emitting toxic gases, contaminating groundwater by the leachate and wasting landfill capacity [4]. Methane (CH4) and carbon dioxide (CO2) emitted as a result of microbial activity under uncontrolled anaerobic conditions at dumping sites are released into the atmosphere and contribute to global warming [5]. Composting is a good idea to reduce the amount of solid waste in the landfill. Composting is a controlled decomposition that natural breakdown process occurs. Composting is the transformations of raw organic materials into biologically stable, humic substances suitable for a variety of soils and plant uses [6]. Organic fertilizers are the end product of composting. Organic fertilizers are natural fertilizer which made up from vegetables, fruits, animals and many more. Organic fertilizers are crucial in agricultural sector because they have positive effect on soil without damage ground water and plants [7].
