Arcadis to gain global license for PFAS treatment technology

Design and consultancy organisation Arcadis has signed a heads of agreement with EVOCRA, and entered into an exclusive commercial negotiation period for sole rights to EVOCRA PFAS solutions technology.

PFAS stands for per- and poly-fluoroalkyl substances, which are manufactured chemicals used in products that resist heat, oil, stains and water.

According to an Arcadis statement, an understanding of PFAS toxicity, environmental persistence and aquifer mobility has developed in recent years.

Arcadis Australia Pacific CEO Malcolm McDowall said Evocra, an Australian-based water treatment company, have developed a patented technology that uses ozone fractionation to separate and concentrate PFAS from impacted media.

“Evocra and their treatment process provides our clients with an innovative solution to cost-effectively remove a complex contaminant from their assets and improve our environment,” Mr McDowall said.

“Their process has been demonstrated at a commercial scale as having the ability to remove PFAS and deliver an output that meets the most stringent discharge requirements set by regulators and other relevant authorities.”

Mr McDowall said the ozone fractionation used by Evocra has benefits over other separation and/or adsorption technologies, especially for liquids that have high concentrations of PFAS, and for complex waste streams with multiple contaminants.

“When the Evocra technology is coupled with either Arcadis developed or other commercially available destructive technologies, we will have the ability to offer our clients a zero-waste outcome,” Mr McDowall said.

University of Adelaide hosts $11M food waste program

Waste from Australian agriculture will be turned into high value products such as cosmetics and pharmaceuticals following a partnership between researchers and industry.

Developed over the past year and officially launched in South Australia, the $11 million Research Consortium Program for Agricultural Product Development will be hosted at the University of Adelaide’s Waite Campus.

The program brings together 18 partners to develop high-value products from agricultural waste, including nine South Australian-based companies from the agriculture and food sector, and a further nine national and international academic institutions and industry partners.

Research Consortium Lead Investigator Vincent Bulone said up to 40 per cent of South Australia’s primary production harvest could end up as waste, left to rot in the field or turned into low value products such as compost or animal feed.

“But all of this food waste contains compounds that have high-value potential applications,” Prof Bulone said.

“Some can act as prebiotics or anti-oxidants; some have anti-inflammatory or anti-microbial properties; others, in particular carbohydrates, provide mechanical strength and texturising properties in food, lubricants, cosmetics and structural materials.”

Prof Bulone said the program plans to increase the value of agricultural waste and create new post-farmgate industries worth over $100 million a year to South Australia.

Research partners include the University of Adelaide, University of South Australia, CSIRO and Sweden’s Royal Institute of Technology.

The consortium received a $4 million South Australian Government grant through the Research Consortia Program.

“Our research will cover the entire value chain from our local growers to manufacturers of food products and beverages, skincare products, and green materials,” Prof Bulone said.

“The focus on applied product development and its web of local, national and international partners will create spin-off companies and jobs to commercialise new, high-value products from existing waste streams.”

Projects underway include:

Isolating and identifying anthocyanins from apples and berries for use in skincare formulations and other health-promoting products

Testing cellulose molecules from waste brussels sprout stalks and other biomass as replacements for glass fibres in filtration systems and plastic materials.

Extracting vitamin D, beta-glucans and chitosan from mushroom waste for use in nutraceuticals and sunscreen materials.

Paying the rent: Select Civil

Waste Management Review explores the streamlined equipment process of Select Civil’s dry plant hire service. 

Managing the purchasing and maintenance of waste facility equipment can be time-consuming, and often beyond the capacity of time-poor site operation managers.

To streamline this process, waste management services company Select Civil supply long-term, full-service, dry hire plants in a range of applications, such as waste transfer stations, green waste processing facilities, alternative waste plants and landfills.   

Renaud Chauvet, Select Civil Managing Director, says the company currently own and maintain 39 plants on long term dry contracts. He adds that the service strives to simplify equipment purchasing and ease of maintenance.

“Waste operators work under harsh conditions and inevitably their machinery breaks down. Select Civil alleviates this problem by providing plant diagnostic and repairs for break down and servicing – we operate like a turnkey solution for mobile equipment,” Renaud says.

According to Renaud, a key challenge when running large-scale waste facilities is multiple points of contact and conflicting information.

“To run a facility of scale, operators need to speak with financiers about capital, suppliers about parts and service companies about maintenance,” Renaud says.

“Whether internal or external, that’s too many voices. With Select Civil there is one point of contact. We handle everything and we make sure the plant is available to do its job when needed.”

When a client engages Select Civil, Renaud visits their site to assess specific operational requirements. From there, he develops a detailed recommendation plan and later makes an offer.

“The process is very transparent. Clients have access to Select Civil’s cost of financing, residual values, as well as budgets for major overhauls, ground engaging tools, tyres, everything,” Renaud says.

“We work with an open book attitude to develop trust with the clients, which means they can focus on their operation and not worry about yellow gear.”

Next, Select Civil opens tenders to original equipment manufacturers to quote on the machinery. To find the best equipment result, Renaud generally invites at least three manufacturers to quote.

“Select Civil has good relationships with tier one manufacturers, and is not tied to anyone brand, but we make sure the equipment is backed up by a solid dealer. That said, we keep our options open when clients are interested in trying less established brands.”

Select Civil then buys the equipment, which has benefits beyond streamlining the decision-making process.

“Large waste facilities don’t always have immediate access to the capital required to procure heavy plants in a timely manner, so renting the equipment side-steps this issue,”
he says.

“Additionally, it’s difficult for original equipment manufacturers to lock equipment resale value in, so we remove that risk for the client.”

Renaud says Select Civil are committed to servicing every piece of equipment after 250 operating hours.

“Most original equipment manufacturers advertise servicing after 500 hours, but because of the typical waste environment, we think it’s best not to stretch it past 250,” he explains

Renaud says many of Select Civil’s plant hire clients began as general waste management and landfill customers.

“When we run their landfill operations, clients invariably realise we are very knowledgeable about the waste industry and the need for well-maintained reliable equipment, as availability is key in our industry.

“Current and recent contracts – some in excess of $10 million – demonstrate our ability to take on, manage and successfully complete large-scale waste projects of any nature.”

Crumb rubber gathering: Tyre Stewardship Australia

Tyre Stewardship Australia hosted a workshop with stakeholders from across the whole supply chain, providing an update on the progress of crumb rubber uptake.

The circular economy is a long-discussed topic as multiple industries recognise the need to shift from the linear economy to one where products are kept in the supply chain for as long as possible.

While the term has been thrown around loosely from time to time, the roads sector is one that has been taking proactive action on material reuse for decades. Turning discussion into action, the Australian Asphalt Pavement Association (AAPA), which represents more than 500 members in the road construction sector, chose to embed this theme into its 18th conference.

Crumb rubber (CR) products are one of the best known and well tested areas that demonstrate the circular economy. CR modified binder has been used in Australia since the mid-70s, although its utilisation has been inconsistent and more common in spray sealing applications.

But in recent times, a more diverse use of CR in pavements has become commonplace through research and development funded by Tyre Stewardship Australia (TSA).

To get a sense of CR uptake, TSA sponsored a workshop at the AAPA Conference in Sydney in August.

The workshop was facilitated Joe Grobler from the Australian Road Research Board and included presentations from TSA Senior Strategy Manager Liam O’Keefe, Puma Bitumen’s Erik Denneman, Tyrecycle’s Clinton Habner and Fulton Hogan’s Darryl Byrne.

The presenters included stakeholders from each end of the supply chain of Australian tyre-derived product in the road sector, from bitumen supply to tyre recycling and road construction.

Mr Habner spoke on behalf of the challenges facing recycling industries that remanufacture end-of-life materials and the benefits that ongoing procurement of their product can provide to the sector.

Mr Denneman discussed the fact that increasing demand from CR binders is already impacting Puma Bitumen – one of Australia’s largest bitumen providers for asphalt products. According to Mr Denneman, we’re no longer waiting for the market to shift – it’s already moving. He also provided extensive technical analysis on trends in the industry.

Finally, Mr Byrne from Fulton Hogan spoke of the fact that as a contractor, he’s seen the benefits of CR binders in creating longer lasting pavements. He explained that the days of trials and demonstrations must give way to normalising use. Contractors are ready to provide the product, however, better manufacturing infrastructure that can accommodate CR and more cost competitive feedstock is required.

“We’ve got about 450,000 tonnes of tyre waste here in Australia. We use a small percentage of that, 10,000 tonnes in bitumen surfacing, [and] I think we can grow that quite rapidly over the coming years, with the aspiration within industry in various forms to get it to 35,000 tonnes per annum,” Mr Byrne said.

The panellists noted that an uplift in volume in CR is starting to occur in asphalt use as modern asphalt plants are able to produce wet mixed CR asphalts though vertical tanks with agitation.

Mr Byrne highlighted that an increase in CR consumption will require investment in equipment and new technology due to a limited number of producers on the market.

As the workshop arrived at the interactive component of the presentation, an audience of road owners/government, contractors, designers, binder suppliers, industry organisations and others were able to vote on a range of questions. More than 60 participants were involved in most questions with road owners/government making up around 40 per cent of the audience, followed by contractors and binder suppliers.

A majority of participants voted that performance drove their product selection followed by initial costs, whole-of-life costs, sustainability and policy. More than 80 per cent of participants are currently using CR, while the barriers stopping its increased uptake were attributed to a lack of infrastructure/supply, followed by a lack of specifications/guidelines and cost.

Around 63 per cent of participants believe adequate specifications/guidelines are not in place and around 40 per cent were unaware if their companies test CR for compliance with the specifications. Around 80 per cent of participants agreed sourcing local tyres was important to them.

Broadly speaking, the main barriers to increasing CR were noted to be cost, health and safety and performance.

Mr Byrne said that road agencies are increasingly changing their practices and predicts an increase in CR in other states and territories akin to how it has been used in Victoria.

One of the key discussion points was that CR has been used in Australia for more than 50 years and it was important all stakeholders stopped referring to these projects as “trials”. While VicRoads has been an industry leader in CR, a need to utilise more passenger tyres and shift the policy in government towards supporting local product manufacture was acknowledged.

In terms of modern specifications, the various states and territories each have their own specifications that support CR uptake and most require they be natural, synthetic and free from contaminants.

Mr O’Keefe said that the conversation reiterated that the industry is primed to provide the product to market, but it’s now the role of end users to “take up the challenge” and procure CR product in greater volume.

ifm O3M photoelectric 3D sensors

The waste industry is increasingly looking towards technology to improve throughputs and drive operational efficiency. With this in mind, ifm has developed a new generation of 3D Smart Sensors to further increase the automation level of mobile machines and drive operational efficiency.

Using the time-of-flight principal, the O3M photoelectric 3D sensor measures the distance between the sensor and the nearest surface point. The unit illuminates the scene with an external infrared light source and calculates the distance by means of the light reflected from the surface.

The O3M’s integrated, automatic object recognition detects up to 20 stationary or moving objects in the vehicle’s path. By comparing the current speed, the motion vector and fixed parameters, such as breaking distance, collision probability is calculated by the 3D sensor and transferred to the machine control system via CAN bus or Ethernet, before being signalled to the driver.

A highly developed algorithm from the automotive sector and a frame rate of up to 50 frames per second allows fast and reliable calculation of the 3D data. Additionally, the specially modulated infrared light enables continuously high recognition rates, even with reflective material of varied intensity.

The O3M is used in waste disposal vehicles for automatic recognition of dangerous situations such as during reversing or placing container bins.

Landfill machine guidance empowers operators: Position Partners

Machine guidance is used in the waste management industry to optimise compaction and give waste facility managers real time data, ensuring fill plans are being followed safely and to design.

Used widely in large metro waste management facilities, machine guidance adoption rates for landfill operations is increasing steadily with council and privately- operated sites realising the productivity gains that can be achieved with this simple yet valuable tool.

One such progressive facility is managed by Toowoomba Regional Council to the west of Brisbane in South East Queensland.

According to Toowoomba Regional Council Water and Waste Portfolio Leader Bill Cahill, the waste facility services a population of around 130,000 people and manages 50,000 tonnes of waste per year.

“Safe and efficient use of our council waste facility is important to ensure its longevity and optimise capacity,” Mr Cahill said.

“Adopting innovative technology is one way to maximise productivity and proactively implement best practice waste management.”

Just over a year ago, the council invested in Carlson’s LandfillGrade machine guidance systems for the landfills 37-tonne compactor and CAT 963 drott.

Carlson’s LandfillGrade solution utilises precise GPS technology, with an easy to follow design displayed in the cab of the machine, which gives the operator a clear visual display of the machine’s position relative to compaction design.

A simple colour code of green for optimal compaction, and blue for over compaction, gives a quick visual reference throughout the working day.

Real time information for the operators enables accurate loading and compacting while minimising air space, with the ability to see how much more is needed on a lift-by-lift basis.

Position Partners Landfill, Mining & Solar Business Manager Andrew Granger said with the operators’ increased ability to work to design without external survey checks, rework is reduced and there is improved safety as batters are graded to design and not made too steep.

“Machine guidance for waste management applications gives accurate and timely reporting capabilities along with certainty that staff and machine operators are working to the latest fill plans,” Mr Granger said.

Position Partners distributes and supports Carlson Landfill machine guidance technology throughout Australia, New Zealand and South East Asia.

“The company has branches in every state and territory of Australia and prides itself on training, support and services for the technology to ensure operators and managers are maximising productivity gains,” Mr Granger said.

Prioritising projects: Infrastructure Australia

For the first time, the 2019 Australian Infrastructure Audit has included waste management in its remit. Waste Management Review speaks to Infrastructure Australia about responding to some of the industry’s infrastructure challenges. 

Since 2008, Infrastructure Australia has advised governments, industry and the community on investments needed to deliver better infrastructure across Australia.

The nation’s independent infrastructure advisor audits nationally significant infrastructure and develops 15-year rolling plans that cover national and state level priorities.

For the first time, the 2019 Australian Infrastructure Audit has included waste management in its remit.

Released earlier this year, the audit examines challenges faced by Australia’s waste sector, including growing pressure from population growth, export bans and heightened environmental awareness.

The audit identifies Australia as one of the world’s largest waste producers per capital, with waste management often poorly planned. The sector is also under increased pressure as waste generation increases and the capacity of infrastructure declines.

It points out that Australia is poised to take advantage of Asia’s economic development, but needs to ensure supply and freight chains operate efficiently to do so.

Some of the challenges the audit points out are well-known to the waste sector, including a lack of private investment and a reliance on exports. Likewise, residential encroachment and increase in waste generation are also widely understood.

An often undiscussed challenge highlighted is the impact that transporting waste over large distances has on the right network, leading to congestion and road degradation.

One of the key focuses of Infrastructure Australia is to take submissions and develop an Infrastructure Priority List that governments can use to guide decision making.

Peter Colacino, Executive Director – Policy and Research at Infrastructure Australia, says that the decision to include waste in the audit was an important one, as the waste sector makes a significant contribution to the national economy.

He says community sentiment is starting to shift with changing user preferences towards recyclable products. Peter says a greater focus on what we consume will leader to a greater focus in community and planning.

Communities have previously found it undesirable to live next to landfills, he points out. But as the sector becomes more sophisticated and moves from landfill to reprocessing, he says a different appreciation of the value of those sites will hopefully take hold in the community.

While its not within the scope of Infrastructure Australia to identify the gaps in buffer protection, Peter makes the point that Sydney and Melbourne are not the only cities growing at a faster rate than public services can support.

The audit shows that satellite cities such as Wollongong, Newcastle and Geelong have capacity to grow and in turn take pressure off infrastructure in the faster-growing cities.

“Sydney and Melbourne are growing rapidly because of the quality of life in those cities and access to essential services and social infrastructure. If we’re seeing places like Wollongong and Newcastle be attractive for people to settle in and therefore take pressure off our major cities, we need to ensure that people that choose to live there have access to the same sorts of services.”

The audit points out that cities can support growth by leveraging infrastructure off their fast-growing neighbours and smaller capitals. The document outlines a number of challenges surrounding waste management.

One was that a limited number of new waste facilities and landfill sites have been approved and residential development was encroaching on existing facilities. Without further action, waste freight will have to transport their loads further from the generation point.

“Encroachment is a complex issue because it’s not only with those nodes like a landfill site or a recycling facility, but it’s also around the transport links that need to be used by the sector,” Peter says.

One of the challenges acknowledge in the audit is that Australia’s freight task, including waste transport, disposal and recycling is growing rapidly. The domestic freight task is growing by 50 per cent and expected to continue to grow by another 26 per cent between 2016 and 2026.

“You do see moves from councils to restrict access of heavy vehicles to particular communities for communities that would be trafficked if you like by refuse vehicles if they were transferring waste rather than treating it locally.”

Peter says by limiting the access of waste vehicles to communities, they are forced to travel further leading to greater deterioration of the road network, increasing the cost of waste management and undermining the commerciality of the sector.

In addition, he says the provision of additional bins is another discussed that needs to be understood within the context of added pressure to the transport network.

“Interestingly, the electricity sector is performing relatively well there’s reduced emissions from the sector largely because of the role of renewables. The transport sector on the other hand has seen a growth in emissions. For local councils that’s important as large fleet owners both in terms of light vehicles and heavy vehicles like refuse vehicles,” Peter says.

He adds that electric vehicles presents an opportunity for emissions reduction in future as price parity occurs over time with potential to transition to autonomous vehicles and hybrids in the present.

Peter says Infrastructure Australia’s process follows three phases.

The first, he says, is to make sure the audit serves its role that it creates a discussion.

“It’s not a document that we want to sit on shelves it’s a document that we want the sector to engage with and use our submissions process to provide us with feedback,” he says.

“Secondly we’ll be working over the next year or more in developing the plan which will include package of reform that we hope are adopted by government and we’ll continue to engage with industry and government as we develop that document.”

He says the third process is to ensure the Infrastructure Priority List can be updated so people can respond to the challenges and opportunities identified in the audit through submissions to the list.

Peter says investment interventions on the Infrastructure Priority List are needed to ensure domestic supply chains are adequate and it can respond to respond of the imperative of government to reduce waste moving offshore.

He adds that going forward there will need to be more commercial thinking around deriving value from waste, including through new products and waste-to-energy.

“What we need to ensure and what is Infrastructure Australia’s role is that significant investment is well targeted and effective and that is the role of our Infrastructure Priority List,” Peter says.

“We also think there’s an opportunity for greater reflection on lessons learnt through post-completion reviews after projects are reviewed to understand if they’ve fulfilled their ambitions that was set out in their planning, whether or not they’re effective and if there’s lessons that can be taken away and applied elsewhere.”

Submissions to the Infrastructure Australia audit will be open to 31 October, for more information click here.

Infrastructure Victoria releases interim waste report

Infrastructure Victoria has published its interim report to the Victorian Government on the infrastructure required to support a changing recycling and resource recovery sector.

According to Infrastructure Victoria CEO Michel Masson, Victoria’s total waste generation nearly doubled between 2000 and 2018, growing from 7.4 million tonnes to 13.4 millions tonnes each year. Mr Masson said stockpiling and illegal dumping are now significant concerns.

Despite this, Mr Masson said after a thorough investigation of the recycling and resource recovery sector, Infrastructure Victoria has identified exciting opportunities for investment, new processes and community action.

“To waste less and recycle more, governments, communities and businesses all need to play their parts. We have all learnt to use less water and power, now we have to apply the same principles to waste,” Mr Masson said.

The report specifically outlines that further investment in organic processing is needed to divert food and garden waste from landfill and reduce methane gas emissions.

“Infrastructure Victoria has identified the food and garden waste should go to more high quality composting facilities, which would need to be supported by a rollout of household organics collection services,” Mr Masson said.

Victoria’s current co-mingled system does not produce sufficiently clean streams to support end markets for recycled materials, according to the report.

“Greater separation of waste in homes and businesses can reduce contamination and improve the quality of our recycling,” the report reads.

“Infrastructure Victoria’s consumer research demonstrates 90 per cent of households surveyed are open to changing how they sort their waste.”

Report findings show best practice jurisdictions separate at least five types of material at the source, including organics, plastics, paper and card, glass and metals.

While multiple calls have been made to introduce a container deposit scheme in Victoria, the preliminary view of the report is that more analysis is needed on how to design an optimal scheme for Victoria.

The report also calls for improved commercial and industrial recycling standards.

“Incentives and price signals need to be examined to improve performance across the board, from manufacturers to retail,” the report reads.

Initiatives to disincentivise the use of virgin materials in production, or promote the procurement of products made from recycled materials, were also highlighted.

Proposed actions include:

Developing a clear, overarching policy framework including recycling targets and waste-to-energy.

Supporting councils to implement more consistent approaches to sorting and collecting waste, helping to reduce contamination in household recycling collection.

Better planning, locating and protecting waste management sites.

Working with the Commonwealth and other states to reduce packaging and single use plastics.

Increasing the use of recycled materials by eliminating barriers and updating government procurement guidelines.

Infrastructure Victoria will deliver its final report on recycling and resource recovery infrastructure in April 2020.

ACOR report examines recycled roads

Australia can significantly boost domestic recycling by replacing virgin resources with recycled materials in road construction, according to a new report from the Australian Council of Recycling (ACOR).

Undertaken by MRA Consulting for ACOR, the report shows that by using recovered soft plastics, secondary glass cullets and passenger tyre crumb in asphalt and/or road base, Australia could double the amount of soft plastic domestically recycled, increase tyre recycling by 50 per cent and help eliminate unused glass cullet stockpiles.

According to ACOR CEO Pete Shmigel, roads are Australia’s largest single asset, and by building them with recycled materials, Australia can deliver the goal of domestically sustainable recycling.

“Our message to governments who build roads is; use recycled content to keep valuable stuff out of tips, deliver value for money to taxpayers and generate more jobs,” Mr Shmigel said.

Mr Shmigel said the report examined 12 roads including Sydney’s Westconnex, the Bruce Highway Upgrade in Queensland and the CityLink Tunnel in Melbourne.

“In reality, some 10,000 kilometers of new roads are being constructed; so regular use of recycled material in roads according to a new standard would be a road-led recycling revolution for regional jobs and environmental benefits like greenhouse gas reduction,” Mr Shmigel said.

“It’s important to recognise that recycled roads – compared to virgin roads – are cost competitive and comparable if not better on quality and longevity.”

Mr Shmigel said 11 of the 12 projects modelled in the report are partly funded by the Federal Government, which can require recycled content as part of funding agreements.

“That’s a great opportunity for our ‘Recycling PM’ to further deliver on his vision,” Mr Shmigel said.

“The choice is before us. Drive recycled roads into a better economic and environmental future, or drive old roads straight to the tip.”

Findings:

Glass: 

Current recycling: 627,000 tonnes or 57 per cent

Additional tonnes from 12 recycled roads: 1.34 million tonnes

Soft Plastics:

Current recycling: 89,900 tonnes or 4.5 per cent

Additional tonnes from 12 recycled roads: 104,500 tonnes

Passanger tyres:

Current recycling: 328,000 tonnes or two per cent

Additional tonnes from 12 recycled roads: 174,000 tonnes

TyreStock win sustainability awards

Tyre Stewardship Australia (TSA) has congratulated Queensland online tyre retailer, TyreStock, for winning a highly respected business award.

TyreStock was announced the winner of the Brisbane Lord Mayor’s Yurika Environmental Sustainability in Business Award at a ceremony in Brisbane on Friday night.

TSA Chief Executive Officer Lina Goodman said TSA was thrilled to see such an innovative business win this award.

“TyreStock is committed to ensuring waste tyres don’t end up in landfill or stockpiled and the award shows that this message is also important to the community and leaders,” Ms Goodman said.

TyreStock promises its customers that their old tyres will end up at Australian recycling plants and it has a tracking system to ensure this. It is also committed to donating some of its profits to charities helping children and families in developing countries.

The small start-up managed to beat some established organisations like Brisbane Airport Corporation and the University of Queensland.

TyreStock CEO William Amiot said the company was pleasantly surprised to win the award.

“It’s overwhelming that Brisbane City Council recognises our mission and embraces the vision we have for our industry,” Mr Amiot said.

TyreStock is influencing how Australia’s waste tyres are dealt with through its participation in the Tyre Stewardship Scheme.

TSA’s voluntary scheme has to date supported the creation of more markets for tyre-derived products like equine tracks, roads and permeable paving.

It has thus far committed five million dollars to the development of sustainable end markets for tyre-derived products within Australia.
