The silent threat: If a circular economy goes wrong

In early 2024, reports of asbestos contamination in mulch products across three eastern Australian states escalated into a significant environmental and health crisis. Contaminated mulch was found at 79 sites, including playgrounds, schools and public parks in Sydney and Melbourne, as well as in compost and mulch products in Queensland. While swift government action resolved immediate threats, the incident underscores broader issues within Australia’s circular economy efforts. Our research highlights the urgent need to mandate certification for recycled products like mulch to ensure safety. Currently, no local, state or national policies on sustainable procurement recommend certification, and resistance to such schemes remains widespread within the industry.
