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.
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.
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 Community Attitudes to Biosolids Survey
- 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
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:
