Ahrens demonstrate leadership in the delivery of waste and recycling solutions, with state-of-the-art Humes StormTrap system.
While Australians are committed to a more sustainable future, they remain confused about fundamental recycling practices, according to Cleanaway’s Recycling Behaviours Report.
A joint venture between Tyrecycle and Kariyarra Aboriginal Corporation will specialise in the processing of end-of-life mine-site tyres.
Shane Walden, Macedon Ranges Shire Council Director of assets and operations, explains the process that led to council’s 2020 introduction of kerbside glass and organics collections.
Mobile telecommunication product stewardship scheme MobileMuster has released its 2019 Annual Report, to coincide with its 21st anniversary.
MobileMuster celebrated its 21st anniversary at The Mint in Sydney, with Telstra Executive Director of Regulatory Affairs and Australian Mobile Telecommunications Association Chair Jane van Beelen and Assistant Waste Reduction and Environmental Management Minister Trevor Evans.
MobileMuster Manager Spyro Kalos said the report examines the schemes performance in 2019, as well as the significant progress of the organisation over the last 21 years.
After 21 years of operation, MobileMuster is Australia’s oldest product stewardship scheme.
“The success of the program to date demonstrates how the industry can work together voluntarily to deliver social and environmental outcomes,” Mr Kalos said.
“We are committed to continuing to invest in the next generation of mobile phone users, educating them about the impact of their mobiles and how to act for a sustainable future.”
Since 1998, the program has collected and recycled nearly 1500 tonnes of mobile phones and accessories, including over 14 million handsets and batteries.
“Further, in this year alone, MobileMuster collected and recycled 84.1 tonnes of mobiles, their batteries, chargers and accessories and through the process, recovered metals, glass and plastics, averting 188 tonnes of CO2 emissions – the equivalent of planting 4840 trees,” Mr Kalos said.
Through the program’s recycling processes, over 95 per cent of the material from mobile phones and accessories is recovered and used to manufacture new products.
“With an estimated 25 million mobiles being stored by Australians, we hope to get more Australians recycling,” Mr Kalos said.
“In addition, we are working towards zero waste to landfill, that means no mobiles will be disposed of in the general waste stream.”
According to the report, MobileMuster has an industry participation level of 92 per cent, including Alcatel, Apple, Google, HMD Global (Nokia), HTC, Huawei, Microsoft, Motorola and Oppo.

The Victorian Premier’s Sustainability Awards is now open for entries and features a new category to celebrate outstanding contributions made by volunteers.
The new environmental volunteering category will recognise the impact made by thousands of dedicated individuals and groups who give their time to sustainability projects and environmental protection.
Sustainability Victoria CEO Stan Krpan said as the most prestigious program of their kind in Victoria, the awards are a terrific showcase of leading edge sustainability practices.
“Through these awards we proudly showcase the businesses, government, schools, institutions and community groups that are leading the way helping to stop the effects of climate change, developing more integrated circular economies and creating a more liveable, engaged, prosperous community for us all,” Mr Krpan said.
According to Mr Krpan, recent research shows that while sustainability remains an important concern for most Australians, only half believe they are doing enough.
“Joining the program’s existing ten categories, the new environmental volunteering category will make the awards more accessible to more people who take environmental action in real, practical and tangible ways,” Mr Krpan said.
The Premier’s Sustainability Awards includes the categories built environment, community, education, environmental justice, environmental protection, environmental volunteering, government, health, innovative products or services, small to medium sized businesses and large business.
2018 winners include small business Yume Food, who won for building a marketplace exclusively for surplus food, the Caulfield to Dandenong level crossing removal project and a campaign by Zoos Victoria and Phillip Island Nature Parks that addressed the threat of plastic debris to marine life.
Entries in the Premier’s Sustainability Awards close on Thursday 13 June.
A new way of tracking how sewage sludge flows during thermal treatment could help engineers design better wastewater treatment plants and boost the production of biogas.
Researchers at RMIT University have demonstrated how the flow behaviour of sludge can be used as a tool to gauge how quickly organic matter is dissolving at high temperatures, suggesting the potential for online monitoring.
Traditional methods of assessing thermal treatment performance require time-consuming sampling and chemical analysis, rheology calculations however – which measure and detail how liquids flow – can be done in real time online.
The study, published in Water Research, found a correlation between how sludge dissolves and changes in its flow behaviour, indicating it may be possible to monitor thermal treatment performance simply by tracking flow.
Lead investigator Associate Professor Nicky Eshtiaghi said correctly estimating the rheological parameters of sludge is critical to efficient process design.
“Our technique enables engineers and plant operators to conveniently obtain these parameters without having to perform the measurements at high temperatures themselves,” Ms Eshtiaghi said.
“We hope the research encourages more serious consideration of flow behaviour in optimising and designing high pressure and high temperature sludge-handling processes.”
The new technique can measure flow behaviour without destroying samples, often a big challenge for concentrated sludge data collection.
The study also shows that varying the thickness of sludge has little impact on the effectiveness of thermal treatment, meaning plant operators could potentially increase biogas production by increasing the solid content of sludge during initial treatment processes.
“Thicker sludge can be beneficial for both optimising efficiency overall, and for producing more biogas,” Ms Eshtiaghi said.
“With our discovery that the thickness of sludge makes no difference, this research gives plant operators more flexibility in designing processes that can better exploit the renewable energy potential of wastewater sludge treatment.”
Yume, an online business to business marketplace for the sale of surplus food, is working with water and environmental services company REMONDIS to sell excess food and reduce waste.
REMONDIS will use Yume’s marketplace to assist customers in selling their surplus products, reducing waste disposal costs and delivering better environmental outcomes.
REMONDIS General Manager for Integrated and Managed Services Nathan Radley said working with Yume allows the company to expand its services on the waste value chain.
“Yume is a great way to access the first two stages of the food waste hierarchy, avoid and reuse, before we move onto recycling, waste to energy and ultimately disposal,” Mr Radley said.
REMONDIS recently listed 13.8 tonnes of maple syrup on Yume, sourced from a customer with excess stock.
“The product was quickly snapped up on Yume, providing a significant return to the customer while saving 952,000 litres of water and preventing the release of 27,600 kilograms of CO2 into the atmosphere,” Mr Radley said.
Yume founder Katy Barfield said through connecting suppliers to buyers, the company helps reduce the 4.1 million tonnes of food waste sent to landfill in Australia each year.
“Yume has already sold over 813,000 kilograms of quality surplus food, returning $2.6 million to Australian farmers and manufacturers.
“In doing so, Yume has saved 56,112 million litres of water and prevented 1,626 tonnes of carbon dioxide from being released,” Ms Barfield said.
At the 2018 Victorian Premier’s Sustainability Awards, Yume was recognised for its efforts towards reducing waste and landfill impact — winning the Premier’s Recognition Award, the Innovative Products or Services award, and the Small and Medium Enterprises award.
Over the next 12 months the Western Australian Better Bins program will be implemented in more than 370,000 households in the City of Joondalup, City of Fremantle and Town of East Fremantle, plus additional households in the City of Melville.
The City of Melville trialled a full FOGO system in 2017-18, returning positive results for the diversion of household organics from landfill.
In its Waste Avoidance and Resource Recovery Strategy 2030, the Western Australian Government outlined food organics and garden organics collection (FOGO) as a priority for waste avoidance and minimisation.
Run by the Western Australian Waste Authority, the Better Bins program aims to ensure that all Perth and Peel households have a third kerbside bin for FOGO by 2025.
Better Bins runs on the principal that more waste separation at the source leads to less contamination and therefore greater recycling and reuse rates.
Under the three-bin FOGO system, food scraps and garden organics are separated from other waste categories at kerbside and reused to create high-quality compost.
The system also functions to keep other waste streams clean and uncontaminated, therefore making them easier to recycle, reprocess and remake into products, reducing the need for extraction of new materials
Currently 16 local governments participate in the program and of these, five are providing a full FOGO service.
After the 370,000 new additions the rate of household participation across the state will stand at 37 per cent.
The Department of Water and Environmental Regulation will soon start consulting with key stakeholders on how to promote and encourage local governments’ adoption of FOGO systems, hoping to increase material recovery to 75 per cent by 2030.
WA has extended the funding application period until 30 June 2019.
The Victorian State of the Environment 2018 report says the Victorian Government needs to align its institutional planning and procurement processes to support the delivery of its planned circular economy strategy.
The report, commissioned by Commissioner for Environmental Sustainability Dr Gillian Sparkes, says five out of six waste indicators are stable.
Indicators used were total waste generation, generation of municipal waste per capita, total food waste generated, diversion rate, littler and illegal dumping and total hazardous waste managed and reported.
While most indicators are stable, except litter and illegal dumping which is improving, the report says the total amount of waste generated is poor and offers two key recommendations to improve the waste situation in Victoria.
First, in 2019 Sustainability Victoria need to develop indicators and implement a comprehensive monitoring and reporting framework to measure delivery of the statewide Waste and Resource Recovery Infrastructure Plan against circular-economy design principals.
Recommendations suggest that from July 2020 this progress should be expanded and a reporting framework that tracks progress put in place, with a public report released annually.
Second, the Victorian Government needs to align its institutional planning and procurement processes to support the delivery of the circular economy strategy and clarify which agencies will be responsible for delivering policy, procurement, program, reporting and regulatory roles.
The report says this alignment should be adopted statewide to enable an orderly transition to a circular economy in Victoria by 2030, with the initial focus being reducing consumption and contamination levels in kerbside recycling.
Recommendations also note that the Victorian Government needs to commit to long-term, systemic, statewide community education to support these transitions and improve long-term system outcomes.
