However, very few studies focusing on direct energy recovery
from food waste by incineration are found in the literature. This
is due to the fact that food waste alone seems ill-suited for incineration due to high moisture contents and non-combustible components (Mardikar and Niranjan, 1995). Typically, food waste is
discarded into the general flow of MSW and converted into heat
and energy by incineration. Kim et al. (2013) studied food waste
disposal options in Korea with respect to global warming and
energy recovery. The food wastes after being dried were discharged with MSW and were burnt at 850 C to approximately
1,100 C. Average electricity consumption for drying was estimated
to be at 649 kW h, which is equivalent to 27,920 MJ of energy per
ton TS of food waste (Kim et al., 2013). The results of incineration
revealed that 37.7 kJ of heat from dryer-incineration of 1 g TS of
food waste was produced
