Through eco schools the schools are required to submit their waste and recycling profiles. This data is gathered by eco schools.
Every school that is part of eco schools is required to fill out this form. The information could be useful for comparing schools waste management techniques. Kids and the public could see which schools are the best and worst at their waste management.

Also by looking at the data maybe it might show some interesting statistics.
