Lesson at a Glance
The lesson at a glance: The food that we put into the bin doesn’t have to go straight into landfill. At ReFood we’ve developed a process that collects and converts food waste into renewable energy and creates a nutrient-rich fertiliser. This lesson describes how the process works, and explains the benefits of food waste recycling.
Learning Outcome
Pupils will gain an understanding of what currently happens to food waste and why recycling food waste makes sense.
Pupils will learn about the process of Anaerobic Digestion.
Pupils will see how food waste can be used.

The ReFood food waste journey
The lesson steps:
1
Play the ReFood process film to your class.
2
After watching the film, talk the pupils through the ReFood process - use the completed ReFood Process (1.3) as a guide, but don’t give it to the pupils, as you will later ask them to complete the process themselves. Finally, talk the pupils through the ReFood poster (1.1), which shows how Anaerobic Digestion is similar to the human body.
3
Split the class into 4 teams. Give each team a wall chart (1.2), process cards (cut from 1.3) both photocopied from the enclosed resources, and a glue stick. Ask each team to stick the process cards in the order that the process should be.
4
Ask one member of each team to read out the order in which they have placed the cards and ask the class to confirm if they are right or wrong. (If not, ask the class why). Please refer to the completed sheet in the pack for the correct order.
