During the September campaign, Food & Co (restaurant Arcada) weighed the food waste. For one week, the food waste was weighed without our knowledge and the food waste was 52g/ serving. The following week Food the weighing and then the food waste was considerably less 41g/ serving.
You can easily influence the climate change with the amount of food waste, so what you take on the plate and not eat up affects every time. In Finland, we throw away food around 20–24 kg of food per person every year, appoximately 100 €.
