A literature review revealed that prompts and commitment were effective tools in reducing the amount of garbage produced at lunchtime. These behavior change tools were then integrated into a pilot program in a New Brunswick school. Therefore, posters were used to remind students and consent forms were used to obtain a commitment to participate. Furthermore, students were given educational materials that promoted litterless lunches. The volume and weight of the garbage produced at lunchtime was then measured.
The litterless lunch reduced the volume of garbage produced by 478.29 in or approximately 1/2 a bag. In addition, there was a reduction in weight by 5.93 lbs.
