From wasted to wanted: the circular economy in motion
Several SUEZ clients had expressed a desire to do better when it came to managing their waste in a more sustainable way. The Queensland Waste Levy introduced from July 1, 2019 meant there was also a financial incentive to do the right thing. One area that contributes to greenhouse gases is food waste going into landfill. Every kilo of food waste that goes into landfill produces 1.9 kilos of carbon dioxide.
Given SUEZ services shopping centres and food-based businesses, it recognised that finding a composting solution that allowed its clients to divert food waste from landfill was the “lowest hanging fruit” within its stewardship of the circular economy
AMP Capital had sought a more sustainable approach to how it managed its waste at its various shopping centres and agreed to become part of SUEZ’s composting pilot program.
AMP’s Gasworks Plaza was one of the early adopters to start collecting and composting food waste. SUEZ partnered with NuGrow – a composting facility headquartered at Ipswich, near Brisbane – to process the food waste from Gasworks and other clients’ premises and turn it into nutrient-rich compost.
SUEZ educated retail staff on the importance of avoiding contamination from ceramics, metals and plastics to maintain compost quality.
- From the program’s inception in August 2018, Gasworks has recycled more than 50 tonnes of organic waste, whilst improving diversion rates from 30% to 47%.
- Gasworks is on track to achieve its 2020 target to divert 50% of their waste from landfill to recycling.
- In September 2019, NuGrow returned the first batch of food waste collected from the centre in the form of nutrient-rich compost, which was then used to nourish the centre’s gardens.
- The Gasworks Plaza is just one business within the pilot program. Since mid-2018, SUEZ has upcycled 600 tonnes of bulk food and organic waste from Brisbane and surrounding suburbs via a dedicated “food waste run”.
