Recovery Strategies

Westpac TYN Summit Waste Auditing

Edge was engaged by Westpac Banking Corporation to conduct composition and contamination auditing at the Westpac TYN Summit, held at International Convention Centre (ICC) in Darling Harbour on Thursday 10 October and Friday 11 October 2019. The purpose of the audit was to enable Westpac to gain insight into the waste diversion practices at the summit and to inform improvements in the organisation of future Westpac events. The audit was also an important step in the broader Westpac strategy of waste minimisation across its branch and corporate network.

A full composition audit was undertaken of both general waste and recycling streams available on site. Bin/bag contents were inspected and separated into a number of streams able to be practically recovered, with the balance being classified as general waste. The TYN summit achieved a 94% diversion rate from landfill across the event period. The overall diversion rate of 94% is a very high result and a very positive outcome. Good signage, bin collection services and communication of the event contributed to the result. With the introduction of a soft plastics service, this result would have been even higher. Future audits should be extended to include waste from setup and pack up of events.
