We weighed the food waste at lunchtime over the period of 4 days and recorded the findings. We then calculated the amount of greenhouse gas was produced using your guidance grid. The waste differed over the days depending on the menu, much less on a jacket potato day, but considerably more on a roast dinner day. Going forward we could compile a questionnaire on the food the children would prefer and would be more likely to eat, which would cut down on waste.
Now it's time to calculate exactly how your school's waste is affecting the environment. Download our food waste calculator to calculate some useful data about how much your food waste costs your school and the planet. Use the impact data to communicate to the school community the importance of not wasting food. You could run an assembly to share your food waste facts and ideas of how your school could cut food waste in future.
