Sustainability at Mardi Gras

Since 2020, Closed Loop has hand-sorted all waste at Mardi Gras. With repurposing rates greater than 80% YoY, the team continue to improve the sustainability ratings and portfolio of Mardi Gras, and event organisers, Audiology.

Starting with 8 waste streams, based on attendee demand and waste inputs, Closed Loop adjusted and considered various recycling opportunities for upcoming events. This has led to an additional 3 waste streams since 2020. The introduction of reusable items also reduced the amount of single-use packaging ending up in landfill.

Sustainable food packaging

Closed Loop provide a Packaging Framework which helps to streamline the use of recyclable and compostable food packaging by vendors onsite. Through our Packaging Framework, we can aim for higher repurposing rates as we know the material inputs. 

The introduction and meticulous implementation of this packaging framework contributes to the epic diversion rates year on year!
