Asbestos contamination in recycled mulch affects Australian communities

Recent discoveries of asbestos in recycled mulch used in various urban areas have raised serious health concerns.

In short:

• Asbestos has contaminated mulch at 72 locations across Sydney and Melbourne, sourced from construction waste.
• The issue highlights failures in national and state recycling policies and certification procedures.
• Researchers advocate for mandatory certification of recycled products to prevent future health risks and ensure material safety.

Why this matters:

The presence of asbestos in recycled mulch typically stems from the inclusion of contaminated materials, like old construction debris, in the mulch-making process. As mulch breaks down or is disturbed, asbestos fibers can become airborne and pose a risk to anyone inhaling these fibers. This concern is heightened in public spaces and residential areas where mulch is commonly used for landscaping and gardening, potentially leading to widespread exposure.
