Why do a waste audit?
A visual waste audit helps to work out how much waste is produced, and what waste types make up the waste stream leaving the school, ending up in landfill. It provides the baseline data against which all waste minimisation progress can be measured in the future.
Audits are also used to collect information about other resources like electricity and water use.
Using visual waste audits to promote waste education goals
Collecting information about your current waste procedures will help to identify the types and amount of waste material and food waste sent to landfill over the number of weeks your school operates in one year (e.g. 40 weeks) and highlight potential opportunities for recovering/recycling resources and minimising the waste stream leaving the school or early learning centre going to landfill.
A visual waste audit is the first step to reducing waste at your centre or school. It involves a visual inspection of external waste and recycling bins to determine how full they are when they are put out for collection. This activity can be run in the morning, using waste collected and stored from the previous day, or in the afternoon using waste collected from the start of the day. Try and select a calm day, wind can result in waste littering the school grounds.
This waste audit should be done more than once to average waste volumes and should be repeated at least once a year to demonstrate your ongoing progress in minimising your waste. Something to celebrate!
This task can be done manually as described in this guide; however, check your local council’s website for an online waste calculator.
