Students engage in a school waste audit to determine the quantities and makeup of the waste generated at their school. This baseline data is collected to calculate the total waste output of the school. Students investigate landfill, co-mingled recycling, paper and organic waste. Based on this data schools can explore how to reduce their waste.
- find out how full the landfill and recycling bins/skips are when collected to measure actual waste output (in m3).
- find out how much organic waste is processed by school (in m3) per year.

Cross curriculum priorities:
Sustainability – OI.5 – World views are formed by experiences at personal, local, national and global levels, and are linked to individual and community actions for sustainability. OI.9 – Sustainable futures result from actions designed to preserve and/or restore the quality and uniqueness of environments.
