The source of contamination is believed to be timber waste from construction and demolition sites that was turned into mulch.
Key Points:
- The source of contamination is believed to be timber waste from construction and demolition sites that was turned into mulch.
- So far, 60 locations in Sydney and 12 in Melbourne have been identified as contaminated with asbestos to various degrees.
- The severity, spread and impact of the issue convince us to call it the largest scandal in the history of Australia’s circular economy.
- A circular economy recycles and reuses materials or products with the goal of being more sustainable.
Scandal is damaging for the circular economy
- Unfortunately, this contaminated mulch raises concerns about the reckless implementation of circular economy principles in Australia.
- More broadly, this scandal could undermine efforts to advance the circular economy in Australia.
- It’s a reminder that the circular economy concept is based on a system-thinking approach, where all elements must work in harmony.
Regulations don’t go far enough
- However, it isn’t mandatory for suppliers to test for contaminants in mulch.
- The fact is existing policies and regulations, such as the NSW Environment Protection Authority’s Mulch Order 2016, failed to prevent mulch contamination.

Why isn’t certification standard practice?
- In 2022 and 2023, working with researchers from Griffith and Curtin universities and our industry partners, we explored the use of recycled product certification schemes.
- We specifically asked for their views on certification schemes for these materials.
- He added:
The cost of certification is a fraction of whatever their marketing budget might be in any single month, let alone a year. - If they can see that their certification becomes part of their marketing budget, then the cost of certification is a single-digit percentage of most marketing budgets.
- If they can see that their certification becomes part of their marketing budget, then the cost of certification is a single-digit percentage of most marketing budgets.
What more can be done?
- Our research identified seven major drivers for adopting certification schemes when procuring recycled materials, as shown below.
