Organic waste refers to garden and food waste only (Schedule 1, level 3) (RSA, 2010). The food waste component represents kitchen waste as well as pre-consumer condemned foods. Organic waste is generally reported as garden, green, putrescible and in some instances notifiable waste.
Data on organic waste is found in municipal IWMPs, landfill records. Since food waste is not separated at household level, little, if any, data is available. Similarly, food waste is not generally separated from general kitchen waste generated at restaurants and food outlets. It is possible to estimate household food waste based on waste characterization studies provided that food waste is used as a separate waste category during sorting. Reports on waste characterisation studies in South African municipalities are scarce as pointed out in section 1.2 above. However, Nahman et al. (2012) estimated the quantities of household food waste generated in South Africa per income group as indicated in Table while Oelofse and Nahman (2012) estimated the magnitude of food waste generated in South Africa as in the order of 9.04 million tonnes per annum.
