Whole School Composting


Due to ongoing school renovations, this year, the majority of students must eat lunch in their classrooms – not the cafeteria, as they have in the past. This has given our students a much closer look at how much food waste is produced every day! As the classroom garbage cans were overflowing daily, school administration asked caretakers to pick up the garbage every day after lunch as well as their usual times after school. This meant that not only the volume of garbage had increased, but so did the consumption of plastic garbage bags. The students in our Green Club knew that this situation needed to be dealt with in a cleaner, more sustainable way. It would be a big task, but they knew that whole school composting was necessary.


The LSF-LST funds were used to purchase 45 L compost bins and compostable bin liners. The lined bins were placed in the hallways so that each bin could be accessed by 2-3 classrooms. A schedule was created so that every day, 2 Green Club members would eat lunch in a junior classroom and help the younger students learn what to put in the compost bin. The Green Club members then brought the bins to the other classrooms and stood at them to ensure that the students used them properly. Each pair of Green Club members committed to 2 lunchtimes per week in the junior classrooms as well as being Compost Ambassadors for their own classrooms. At the end of each week, the compostable liners are collected and brought to a larger compost bin, which is brought outside and picked up by the city. The Green Club has taken these responsibilities very seriously and worked so hard to teach the younger students, that we now see younger students contributing to the compost bins throughout the day, on their own. For a small school of 300 students, we are now amassing an average of 50 kg of compost per week and classroom garbage cans no longer need to be emptied during the day.

Reflection & Celebration

The students and staff of our school are extremely proud of the Green Club members who have designed and carried out this very successful project. We see the positive effects of this project every day and this reminds us of the important difference we are making in our school and community. We will continue this project next year and hopefully complete the cycle of compost by using a tumbling composter and using compost in our planting projects in the future.
