FEBRUARY 2013 WATER 29 AWA News Conversely, overestimation of emissions may lead to an excessive carbon price liability. A recommendation is made in this paper that additional research is carried out by the water industry in partnership with the Department of Climate Change and Energy Ef ciency to make more accurate the methodologies employed to estimate carbon emissions arising from biosolids processing. Biosolids are a potentially valuable resource, the use of which could contribute to the delivery of a low-carbon economy. While it is most unlikely that wastewater facilities will generate carbon credits from biosolids, there is an opportunity for their value in delivering reduced carbon emissions in downstream activities to be recognised. There are three ways in which the downstream uses of biosolids could deliver lower carbon outcomes and derive additional value from biosolids use: 1. Use of biosolids as a replacement fuel for coal/gas or as a source of biogas, or to generate renewable energy certi cates (RECs). 2. Use of biosolids as a substitute for inorganic fertilisers. In these circumstances, biosolids' value could be derived from: • Its cost falling relative to inorganic fertilisers as the impact of carbon tax on the cost of the product will be lower; and • Through the development of a methodology under the Federal Government's Carbon Farming Initiative (CFI). 3. Incorporation of biosolids into soils to sequester carbon, where a CFI methodology could be created whereby landholders incorporating stabilised biosolids could generate carbon credits. The introduction of a price on carbon may enhance biosolids' value to downstream users. To realise this value, however, further effort will need to be directed to demonstrating bene t more clearly. AECOM recommends that the ANZBP undertake further work on biosolids end-use products to determine where the greatest value lies and to identify speci c barriers to biosolids uptake by end-users. While on balance the carbon credit opportunities arising from improved biosolids management techniques may not outweigh the entire carbon cost of the wastewater treatment process, it is important to recognise that this issue is shared across the entire water cycle and is not a responsibility of only the biosolids sector to manage. Biosolids management groups are, therefore, not alone, and the opportunity exists to engage other groups working across water management to seek improved outcomes. The ANZBP is committed to working with its members and the wider water industry to address these issues and will work with the sector to explore opportunities to address the concerns at a national level, and will initiate further discussion with members in the near future. If you have speci c comments on the report, or are participating in similar activities, please contact the ANZBP Project Manager. The Discussion Paper, and an accompanying presentation, can now be downloaded from the homepage of the ANZBP website: www.biosolids.com.au. To hear about the paper in more detail, and the Partnership's opinion on the Carbon Pricing Mechanism, AWA is running two Carbon Tax Workshops. Please go to www.awa.asn.au/Carbon_ Tax for more information. ANZBP would like to thank the project consultant, AECOM, for the development of the Discussion Paper. New Technical Editor Announced AWA has announced the appointment of Chris Davis as new technical editor of Water Journal, taking over from Clare Porter who left recently to take up a position with the National Water Commission. Chris knows AWA well, having been a member since 1982. He also held the role of CEO between 1992 and 2007 and, more recently, became an honorary Life Member. After 40 years spent in a variety of other roles, including as a National Water Commissioner, Chris certainly knows his way around the water industry. In addition to his new AWA appointment, Chris is Chair of the Independent Water Advisory Panel for the NSW Metropolitan Water Directorate. New President for YWPs AWA welcomes Jo Greene as the new President of the National Representative Committee for the Young Water Professionals. Jo is an environmental engineer and currently part of the Water Ef ciency team at Hunter Water Corporation. Before joining Hunter Water, she worked at Sydney Water in the areas of stormwater, environment and sustainability, and project management of large capital projects. Jo is keen to take up the reins and sees 2013 as a year of great opportunity for the NRC to lead the YWPs to achieve more, particularly with their national mentoring program and a greater presence at Career Fairs throughout the country. Jo has taken over the position from Mike Dixon who moved to the US late last year to take up a new role with Nano H2O in Los Angeles. Branch News Victoria Victorian Water Awards 2012 Leaders in the Victorian water industry were recognised at the 4th Annual Victorian Water Awards held in December. Winners will be automatically entered into the equivalent category in the 2013 AWA National Awards to be announced in Perth at Ozwater'13 in May. 2012 INFRASTRUCTURE PROJECT INNOVATION AWARD: YARRA PARK RECYCLED WATER TREATMENT FACILITY Winner: Tenix Tenix has built Victoria's largest underground Recycled Water Treatment Facility (RWTF), capable of producing 180ML of Class A recycled water annually. The project was designed to meet the requirements of the Melbourne Cricket Club, with the water used to provide secure, long-term supply to the heritage-listed Yarra Park, Punt Road Oval, and toilet- ushing at the iconic MCG.
