ANZBP Fact Sheet on Biosolids & PFAS

Dear ANZBP Members and Stakeholders,


The Australian and New Zealand Biosolids Partnership (ANZBP) is pleased to present its newly crafted ANZBP PFAS & Biosolids Factsheet. The intent of this factsheet is to provide interested parties with information about our understanding and management of per and polyfluoroalkylated substances (PFAS) in biosolids.

The factsheet explains:

  • What biosolids are and why they are important?
  • What are PFAS?
  • Why we are interested in PFAS in biosolids?
  • How PFAS are managed in biosolids and ANZBPs’ position on PFAS in biosolids?

The Heads of EPAs of Australia and New Zealand (HEPA) have released the draft per- and poly-fluoroalkyl substances National Environmental Management Plan (PFAS NEMP) version 3.0 for public consultation. This version 3.0 contains important new guidance and standards, which builds on version 2.0 published in 2020.

You can now have your say on this plan.


We’re excited to share the ANZBP 2021/2022 Year in Review report.

The report provides insight into all that we achieved, including our: 

  • Biosolids Production and End-Use Survey
  • Quantitative Risk Assessment Biosolids Case Study
  • Lunch & Learn sessions
  • Coffee & Cake sessions
  • Webinar series
  • Ozwater presentation and Members Meeting
  • Advocacy and Communication 

Thank you for your support and assistance in making last year a successful one. We look forward to working with you to continue building on our strengths in the year ahead!

Australia and New Zealand Biosolids Production and End-use survey 2021

In 2010, the Australian & New Zealand Biosolids Partnership (ANZBP) commissioned a national survey to identify the main features of biosolids management across Australia and New Zealand. The survey was repeated in 2013, 2015, 2017, 2019 and again in 2021.
Surveys to 2019, inclusive, catalogued and reported the following primary parameters:
• Biosolids production;
• Biosolids end use;
• Biosolids stabilisation grade;
• Biosolids contamination grade; (added in 2013)
• Biosolids primary stabilisation process;
• Biosolids dewatering process.

This year additional data has been collected to both update the survey in line with current and predicted trends and to obtain data that is anticipated to be useful to ANZBP members and government departments. These data are:

• Biosolids secondary stabilisation processes;
• End-use management and branding;
• Stockpile volumes;
• Transportation of biosolids to end-use site;
• Emerging contaminant management;
• Renewable energy production.
The final reports of the survey are now available for ANZBP members on the Member site of the ANZBP website. If you are an employee of ANZBP partners and need access to ANZBP resources and data, feel free to reach out to ANZBP Program manager.



Melbourne Water Biosolids Case Study – Quantitative Risk Assessment

Following the presentation on Quantitative Risk Assessment from Daryl Stevens (PhD) (Atura), Philip Wilkie (Melbourne Water), Nick O’Connor (Ecos Environmental Consulting) in ANZBP September Biosolids Lunch&Learn Webinar.

The Australian & New Zealand Biosolids Partnership has released a Case Study report: Biosolids Case Study – Quantitative Risk Assessment.

The QRA was developed by Melbourne Water with international peer-review from the Imperial College London. The QRA analyses potential pathways of chemicals/contaminants found within wastewater from the wastewater treatment process through to the end-use of biosolids. 

The QRA provides valuable data to Melbourne Water for biosolids land application.

Community Attitudes to Biosolids Survey – Public Report Released

The Australian & New Zealand Biosolids partnership, an industry program of the Australian Water Association, has released a public report based on a survey conducted by Newgate Research of over 1200 people in Australia and New Zealand.  

Survey topics in the publicly available report include awareness and understanding of biosolids as a by-product of wastewater treatment, and the most acceptable uses for these by-products according to community sentiment. The survey also tested the effect of information about biosolids on community attitudes. The full report available to ANZBP program subscribers contains detailed results of this part of the survey. 

Subscribers to the ANZBP program support industry-wide initiatives like the Community Attitudes to Biosolids Survey. For more information or to subscribe contact the ANZBP program manager. 

COVID-19 and Biosolids

The ANZBP Chair and Committee have synthesised available research material to develop a factsheet on COVID-19 and biosolids. 

Indications are that while the virus may be detectable in faeces in small quantities, if the virus was to arrive at a treatment plant in a viable state (which has not been demonstrated) it would be readily destroyed by the treatment methodologies already in place to manage other pathogens.

Biosolids and Microplastics

In light of international interest in the possibility of microplastics contamination of agricultural land and waterways via the application of biosolids, the ANZBP have been working on a preliminary assessment of the risk of this emerging contaminant in the Australian and New Zealand context.

We have made available a preliminary report and a factsheet on this topic. 

The ANZBP supports the reduction of plastic use in consumer products, particularly those that may end up in the sewer system such as clothing fabrics, and substitution of plastics in consumer products with sustainable alternatives.
