Welcome to the ANZBP website

Biosolids Gasification Webinar 

15 July 2020

In this 2 hour webinar, ANZBP Chair Kelly Hopewell will be guided by Johanna Johnson, Mark Newland and Mark Thompson on a virtual tour of the Loganholme gasification plant with video footage of its operations during a trial run.

Damien Batstone from the Advanced Water Management Centre at the University of QLD will give a technical talk on Thermal Treatment of Biosolids, and Kelly, Damien and our Loganholme tour guides will be available for a live Q&A session. You can also hear about what the ANZBP have been up to, including updates on our biosolids production and use data collection and our Community Attitudes to Biosolids survey.

Please note that registration closes 24 hours prior to the event and the Zoom webinar link will be sent to registered participants at this time.

When: 11am AEST 15 July 2020
Where: Online

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.

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.


Community Attitudes to Biosolids Project 2020

The ANZBP is undertaking a large-scale survey of Community Attitudes to Biosolids. Building on the 2009-2010 Community Attitudes to Biosolids survey which informed our work over the past decade, this survey will suggest future directions for the work of the ANZBP, particularly our communication materials. ANZBP members organisations will be able to access the final reports for their own communication purposes. 

Newgate Research have been commissioned to undertake the survey and have created a one-page flyer to help members understand the full purpose and methodology of the survey.

About our Partnership

The Australian & New Zealand Biosolids Partnership (ANZBP) is a member based collaboration of utilities, consultants, academics and government bodies committed to the sustainable management of biosolids. Formed in 2007 as a self-funded program of the Australian Water Association, the ANZBP has over the years developed a diverse range of research products and tools to support the objectives of our members and to further the development of the sector as a whole. These materials are all available via this site, some available to all, others accessible by members only.

The ANZBP has developed this site to provide interested parties with factual information about biosolids, how they are produced, what is in them, how they might be used, their benefits and potential risks associated with their use. The ANZBP believes biosolids are a valuable product, and this website provides information that supports the application of biosolids to land and other appropriate uses.

If you are an Australian or New Zealand producer, processor, transporter or user of biosolids, or a consultant working in these areas, you can join the Partnership.


Our members’ only site offers a rich and diverse array of research and support materials to partnership members, ranging from technical research on odour, carbon and chemical contaminants through to communication and media tools to support community engagement.

Our most recent publications include:

  • 2020 Biosolids Production and Use 2009-2019 Data Consolidation Report
  • Biosolids Production and Use data 2018-2019
  • Assessment of Emergent Contaminants in Biosolids (Chemicals of Concern Report) 2017


Member access is available to all staff of our subscribing partners. Please check your eligibility here and contact us for access if you work for one of our partners.


Our public resources are freely available to enable all stakeholders in biosolids production and use to gain more insight into the processes that create biosolids and ensure their safe use in our communities. These include:
