3.2 Physical Properties of Food Waste
3.2.1 Food Waste Generation
Figure 4 shows the weight of food waste generated during weekdays, while Fig. 5
shows the percentage of the food waste per total waste generated. Overall, the highest
amount of food waste was collected on Wednesday which is 30.9 kg, while the lowest
amount collected was on Monday with 23.1 kg. In terms of percentage of food waste
per total waste, the value was in a range of 72.4–79.5%. It can be seen that the
difference are not much significant for both weight and percentage of the food waste
collected for each day. Further statistical analysis of this difference was reported in
Sect. 3.2.4.
