Question
Has a Waste Audit been completed for the building in the past three years?
Applicability
Applicable to Office, Healthcare, Enclosed Shopping Centre, Universal and Multi-Unit Residential buildings
Answer
Yes – audit conducted every three years, and waste sampling took place over one day
Description
Improving waste management practices requires knowledge regarding the nature and mass of waste collected on-site. Often data provided by waste haulers is not always based on weighted data, making a reliable analysis of a building’s performance impossible. Regular auditing of the waste generated on a site is therefore recommended to gain a more accurate understanding of the volume of waste generated, size of different waste streams and where waste is taken once it leaves the building site.
Requirements
-
The Waste Audit must address:
-
- The time period and duration of waste sampling
- The sample size representing a minimum of 10% of the building’s waste and recycling materials and reasons why the sample is representative
- Details specific to each stream and if each stream has an available program locally for collection for recycling or reuse
- How the waste data was categorized, evaluated and analyzed based on its composition (the site must be equipped with a minimum number of worktables, precise scales, and mobile containers for weighing the waste)
-
- The Waste Audit Report must include:
- Summary of the sampling protocol and methodology used
- Total of each waste stream and overall total waste
- Audit diversion rate
- Audit capture rate
- If data is extrapolated to represent annual waste weights or volumes, describe the calculation methodology used
- Summary of recommendations for improving waste diversion
- Suggested implementation plan for recommendations
- Credentials of third-party who conducted the audit
Documentation
- Custodial Effectiveness Assessment Report
- Credentials of person(s) conducting the assessments
- Photos, etc. demonstrating corrective actions addressed
- P4.0a – Waste Audit Template

Other Notes
Waste audits conducted with the exclusive use of cameras in bins are not admissible.
At a minimum, a waste audit should be carried out every three years. Annual audits are recommended. Auditing is a scientific approach aimed at collecting precise data about the characteristics of waste, including its mass, composition, waste stream and methods of disposal. To be credible, auditing should be conducted using a trustworthy methodology. In addition, it should clearly establish the different criteria and methods of evaluation, as outlined in an initial protocol
