Ask the guest to explain what happens in school to the classroom materials they recycle and throw away. If possible, take an in-school field trip with the building services manager during the day that trash and recyclables are to be picked up by the contractors. Ask the manager to explain where the trash and recyclables will go. Make adjustments as needed. Prior to doing this activity arrange this in-school field trip with the building services manager and the cafeteria manager.
Schools already have an established recycling procedure for handling cafeteria waste.
Arrange for your class to remain after their lunch, or return at the end of all lunch periods, to see how the cafeteria waste is handled. Ask the building services manager and cafeteria manager to explain the waste disposal process used and why. Ask them to include where the waste goes when it leaves the school. Usually a lot of food is thrown away each day in the cafeteria. Add new habits as needed.
