Equipment specifically designed for blending crumbed rubber and bitumen has been installed and commissioned for the first time in Australia by Fulton Hogan, in partnership with Tyre Stewardship Australia (TSA).
With the export ban on waste tyres fast approaching, Eldan Recycling’s Carsten Nielsen speaks with Waste Management Review about a tyre processing system that can produce 99.9 per cent output purity.
A street in Melbourne’s City of Yarra is set to be paved with recycled tyres, with a new technology that reduces waste, encourages tree growth and prevents pollution.
As the circular economy is growing all over the world and demand for high-quality recycled products increases, one of the most important factors is ensuring output purity.
According to the World Business Council for Sustainable Development’s Tyre Industry Project, the world is projected to generate approximately one billion end-of-life tyres each year.
Tyrecycle moves to expand its operations in Sydney with a new state-of-the-art manufacturing plant.
Tyre Stewardship Australia (TSA) has joined the International Rubber Study Group (IRSG), an inter-governmental organisation composed of rubber producing and consuming stakeholders.
According to IRSG Secretary-General Salvatore Pinizzotto, the group has 36 members countries and over 100 members covering the entire natural and synthetic rubber value chain.
“IRSG is the sole multinational body dedicated to discussing the many issues that affect natural rubber and synthetic rubber production, usage, trade and recycling,” Mr Pinizzotto said.
“We welcome TSA into our group and look forward to hearing their ideas and sharing our knowledge.”
TSA CEO Lina Goodman said the membership will ensure TSA connects directly with government officials on a global scale.
“It gives TSA a far greater insight into current global trends, and how this affects what happens to Australia’s waste tyres,” Ms Goodman said.
“We are also working with a global quality assurance organisation, Intertek, to verify what happens to Australian waste tyres that are currently exported overseas.”
Ms Goodman said working with IRSG will also allow TSA to help state and federal government’s gain a better understanding of the current foreign trade in waste tyres.
“This membership gives TSA and Australia better global connections, better information, and will lead to better outcomes for waste tyres,” Ms Goodman said.

A new analysis for the Australian Council of Recycling (ACOR) by independent consultancy firm Equilibrium has estimated the cost of mandatory product stewardship schemes on consumers.
The analysis looked at mandatory product stewardship approaches for different products, and estimated the potential dollars per unit that a mandatory scheme would cost.
Under the current Product Stewardship Act 2011, schemes can be established for a variety of different products and materials to lower their lifecycle impacts.
Mandatory schemes involve enabling regulations to be made that require some persons to take specific action on products, according to the analysis. This could include restricting the manufacture or import of products, prohibiting products from containing particular substances, labelling and packaging requirements and other requirements for reusing, recovering, treating or disposing of products.
For a mandatory e-waste scheme, the cost is estimated to be between $1.55 and $1.85 for an e-waste unit size equivalent product of 0.75 kilograms. For mattresses, the cost of a mattress unit (standard double size) would be between $14.50 to $16.50. A mandatory tyre scheme would cost about $3.50 to $4.00 equivalent passenger units.

ACOR CEO Pete Shmigel said the Australian community has long supported recycling and overwhelmingly wants to be able to recycle more products and items.
“This new data shows that we can do so affordably. In all cases, the cost of recycling these items is likely to be lower than two per cent of their consumer price. Therefore, cost concerns should not be a key barrier to action by our policy-makers,” he said.
Mr Shmigel said that recycling of these items is a well-established practice overseas, including in much less developed countries, and it is difficult to understand why it is not here too.
“Indeed, the formal review of Australia’s Product Stewardship Act has disappeared and is significantly overdue, the new National Waste Policy has a blank space for product stewardship, and there has been no news following ministers’ apparent discussion of product stewardship at the December 2018 Meeting of Environment Ministers.”
ACOR also believes the major political parties need to make commitments in the areas of recycling infrastructure investment, incentives for and procurement of recycled content products and community education. It has submitted industry analysis for consideration.
Equilibrium Managing Director Nick Harford said that while they can be improved, the current co-regulated TV, computer and mobile phone product stewardship schemes are producing good results. He added that there has been no demonstrable consumer concern about their cost.
“While the current schemes are not mandatory, and research estimates that mandatory schemes may have higher administration costs, the estimated cost per unit in relation to the total product cost is generally reasonable,” he said.
The analysis of the potential impacts of mandatory schemes covered factors including:
- Collection and transport
- Processing and recycling
- Compliance, monitoring, audit and reporting
- Safety and environmental management
- Marketing, communications and education
About one quarter of a tyre stockpile in the Victorian town of Numurkah has been removed – equating to an estimated tonnes of 1200 tyres.
Environment Protection Authority Victoria (EPA) used its powers at the end of last year under the Environment Protection Act 1970 to enter the site, with the assistance of Moira Shire Council and funding from the Victorian Government.
Located in Victoria’s Goulburn Valley Highway, the stockpile on privately-owned land has a stockpile of an estimated 500,000 tyres.
EPA Victoria North East Region Manager Emma Knights said the disposal of the tyres was going well.
“The project has been carefully planned, and the tyres removed so far have come from the sides of the stockpile where the hazards are most critical,” Ms Knights said.
“Aerial pictures taken by an EPA camera drone late last week show piles of waste tyres have been removed from the eastern side, closest to homes along the Goulburn Valley Highway. The southern side, which faces several business premises, is currently being removed,” she said.
The removal began in mid December with up to eight trucks a day leaving the site, five days a week, and the whole project is estimated to take approximately 10 weeks.
“The work is progressing well and we are on schedule, although the completion date will depend on the weather, including any days of total fire ban,” Ms Knights said.
The stockpile has been a concern to the community for some time.
“Tyre fires are notoriously difficult to extinguish and produce considerable amounts of toxic smoke. With an estimated 5000 tonnes of waste tyres at the site, CFA has already warned of serious consequences if a summer grass or bushfire spreads to the stockpile,” she said.
The clean-up was carefully planned to include fire safety, security and wildlife and vermin management. Firefighting equipment is located on site for the duration of the clean-up, and no snakes have been observed so far during tyre removal.
The waste tyres are going to a licensed facility in Melbourne for recycling. Once they have been shredded, waste tyres can be put to use in the construction, manufacturing and automotive industries, in the form of products such as athletics tracks, brake pads, new tyres or road surfacing.
