Fig. 5 shows the plate waste for other food categories (excluding meat) and meat during both stages. Total plate waste excluding meat varied from 2.89 kg (an outlier value) up to 24.25 kg (stage one) and from 11.70 kg up to 20.00 kg (stage two). Meat waste ranged from 0.55 to 3.65 kg (stage one) and from 0.10 to 2.85 kg (stage two) (Fig. 5). Per capita meat waste was also reduced from 18.3 g in stage one to 10.1 g in stage two (p < 0.05). One of the factors determining the wastage is the menu composition. As said before menu composition determines the amount of food wasted, with observed variations of food waste consumption from 39 to 5% according to different menus (Ferreira et al., 2013). The menus which promote high plate waste were avoided or even eliminated from the canteen menus after information from the project.
