Asbestos in Mulch: Lessons from Sydney’s Contamination Incident
The recent discovery of asbestos contamination in mulch across multiple sites in Sydney has raised significant concerns for businesses, local councils, and the public. This incident highlights the critical need for stringent material testing, regulatory oversight, and proactive risk management to prevent asbestos exposure.
For operations managers, landscapers, construction and project managers, recycling facilities and home renovators and gardeners, understanding how such contamination occurs—and how to prevent and manage it—is crucial for workplace safety and compliance.
How Did Asbestos End Up in Mulch?
Asbestos contamination in mulch typically occurs due to:
Poor Waste Screening – Recycled construction and demolition waste may contain asbestos if not properly sorted.
Lack of Compliance Checks – Suppliers failing to adhere to EPA and WHS regulations for processing and testing recycled materials.
Cross-Contamination – Mixing clean mulch with improperly screened material from high-risk sources.
Could This Have Been Prevented?
Yes, and here’s how:
Strict Source Control: Ensuring recycled materials come from verified, asbestos-free sources.
Comprehensive Testing & Screening: Regular laboratory testing of mulch batches before distribution.
Stronger Regulatory Enforcement: Increased oversight and auditing of waste processing facilities.
Supplier Due Diligence: Businesses and councils must verify compliance with waste management and asbestos regulations before purchasing materials.
Managing Asbestos-Contaminated Mulch
When asbestos is found in mulch, a structured response is necessary to mitigate risks:
Immediate Site Containment – Restrict access to affected areas and prevent further distribution.
Testing & Risk Assessment – Conduct laboratory analysis to confirm the presence and extent of contamination.
Regulatory Reporting – Notify relevant authorities such as the NSW EPA and SafeWork NSW.
Safe Removal & Disposal – Engage licensed asbestos removal professionals to manage the cleanup.
Ongoing Monitoring – Conduct follow-up air monitoring and soil testing to ensure the site is asbestos-free.
