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.

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.

The convenience model: TOMRA

Markus Fraval, TOMRA Collections Strategy Director, highlights competing Container deposit scheme models and Return and Earn’s success.

When the Tasmanian Government announced it would implement a container deposit scheme (CDS) by 2023, it became the seventh state or territory to do so, leaving Victoria as the single holdout.

The CDS waste collection model is similarly growing overseas, with widespread uptake in North America and Europe. While all CDSs share a common goal, there are multiple implementation models including return to retail, convenience kiosks and large-scale drop-off depots.

Markus Fraval, TOMRA Collections Strategy Director, says most European CDSs operate under a return to retail system. He says this is generally supported by government regulated extended producer responsibility legislation.

“Businesses that sell drink containers are obligated to take the container back in some way, and because it’s so easy, those markets typically achieve 90-per-cent-plus return rates,” he says.

“We commonly employ South Australian style models in Australia, whereby people are required to go out of their way, generally to an industrial area, to return their containers.”

According to Markus, depot models require significant time and organisational commitment from consumers and, as such, are often ineffective. He adds that in lieu of return-to-retail legislation, conveniently positioned reverse vending machine kiosks are a more effective model for Australia.

Markus says despite New South Wales not having the benefit of a return to retail network, the Return and Earn system was designed to be as similar to the European model as possible.

He says this was achieved by positioning reverse vending machine kiosks in shopping centres and supermarket carparks throughout
the state.

“Accessible kiosks allow consumers to participate in the scheme as part of their normal routines and daily habits,” Markus says.

“This provides incentives for positive consumer behavioural change that are not too extreme or inconvenient.”

TOMRA, in a joint venture partnership with Cleanaway, was appointed Return and Earn network operators by the New South Wales Government in 2017.

The role incorporates network design, establishing new drop-off facilities and maintaining the
state’s more than 600 existing collection points.

“We know from our experience in over 40 global deposit markets that the big drivers for successful return rates are deposit value or financial incentive, and the level of returning convenience,” Markus says.

He suggests TOMRA’s focus on convenience and access is the reason that in just under two years, 55 per cent of New South Wales residents have participated in the scheme and return rates have been high.

Since commencing on 1 December 2017, Return and Earn has collected more than two billion containers through a combination of TOMRA kiosks and more traditional depot collection points.

“The first billion containers were collected in the first 12 months of the program, with the next billion collected in the following seven months. This suggests the scheme is still accelerating,” Markus says.

“Return and Earn is now averaging well above four million containers per day.”

While reverse vending machine kiosks represent only half of the total collection points in New South Wales, Markus says approximately 80 per cent of all returns come through TOMRA reverse vending machines.

“It is critical for a successful CDS to have a network of small footprint collection points capable of high capacity collections,” he says.

“It’s also important to facilitate an integrated supply chain that spans collections, logistics and processing.”

Markus says while collection quantity is key, CDSs need to operate as efficiently as possible to keep price impacts at a minimum.

“As network operators, TOMRA Cleanaway has processed well over 100,000 tonnes of material for commodity trading in domestic and international markets,” Markus says.

“For instance, we ship bales of aluminium cans overseas for smelting and remanufacturing into sheet metal, which can then be used to produce new beverage containers.”

Additionally, Markus says roughly half the plastic sold by TOMRA Cleanaway is used for domestic bottle-to-bottle manufacturing, with the remaining half exported oversees to make bottles, textiles and plastic films.

TOMRA’s optical sorting and reverse vending machine technology is available to all operators across the CDS spectrum.

“Our technology scans bottles from 360 degrees, taking one gigabyte of images per second,” Markus says.

“The speed and ease of use of our machines allow TOMRA to collect more than 40 billion containers through reverse vending machines around the world each year.”

According to a recent state government survey, over 85 per cent of New South Wales residents support Return and Earn.

“There are different models out there, and while I think it’s useful for people to understand the success of CDSs more broadly, there is something to be said for the New South Wales model,” Markus says.

“It is undoubtedly the most convenient scheme in Australia.”

Pelletising polypropylene: Applied Machinery

Daniel Fisher, Applied Machinery Project Manager, wants to revive domestic plastic recycling through sustainable Polystar pellets. 

The recycling conversation is becoming more layered and complex by the day, with notoriously problematic plastic often taking centre stage. While the problem of plastic waste is widely understood, manufacturing processes still heavily rely on the material.

Daniel Fisher, Applied Machinery Project Manager, says responsibly processing plastic while keeping up with demand requires straightforward remanufacturing options. He adds that one such option is recycled plastic pellet production.

Daniel says to implement a wider uptake of recycled pellets in the manufacturing industry, resource recovery operators need simple-to-use equipment.

“When dealing with a difficult waste stream such as plastic, it’s common for operators to think that a more complex system will perform better,” Daniel says.

“But as the exclusive Australian distributor of Polystar Machinery, Applied Machinery is committed to supplying customers with straight forward and cost-effective solutions.”

Applied Machinery has worked with the Taiwan-based recycling equipment manufacturer for four years.

Polystar manufactures a range of one-step machines designed to reprocess multiple waste streams, notably polyethylene and polypropylene flexible packaging material.

Polystar technology is designed to be simple to operate and easy to maintain.

“The recycled output result is high-quality plastic pellets that can be repurposed back into manufacturing straight away,” Daniel explains.

“The pellets save waste disposal costs by producing a saleable product, while also offering an alternative to raw material extraction.”

Applied Machinery can offer customers the full suite of Polystar products, including the Polystar HNT and the Polystar Repro-Flex.

“HNT machines are typically suited for flexible, post-industrial film and have the added benefit of being able to produce quality pellets from even the most heavily printed packaging material.”

Daniel says the Polystar Repro-Flex is suited to multiple recycling applications including plastic bags, film scraps, bubble wrap, shrink film and laminated film.

“Repro-Flex machines also work well for post-industrial film waste, as the system can process washed flakes, scraps and pre-crushed rigid plastic waste from injection and extrusion,” he adds.   

Both the HNT and Repro-Flex feature an integrated cutter compactor, which removes the need for pre-cutting.

“The cutter compactor, which generates frictional heat during the compacting process, also helps remove moisture from the material.”

According to Daniel, eliminating moisture is a particularly significant feature when generating recycled plastic pellets, as even minimal water can render a whole batch unusable.

Daniel says the integrated Polystar system also eliminates the need for separate crushers and the common problem of inconsistent feeding.

“The integration of the cutter compactor and extruder ensures extremely fast and stable feeding, as the tangentially connected extruder is continuously filled with pre-compacted material.”

Ejecting for efficiency: Wastech Engineering

After Citywide developed an operational efficiency plan to boost productivity and payloads, It engaged Wastech Engineering for a new fleet fleet of Clearline Waste Transfer Trailers.

When the City of Melbourne announced it would fast-track the delivery of its Waste and Resource Recovery Strategy in early August, it illustrated a commitment to growing the state’s resource recovery capacity.

Similarly, the Victorian Government allocated $35 million to waste and resource recovery via the state budget in May. Both initiatives highlight a pledge to develop more efficient waste processing capabilities across the state.

Increasing productivity via efficient processes is a motivation shared by Melbourne City Council subsidiary Citywide, which recently revised its operational efficiency plan.   

Travis Martin, Citywide Commercial Waste Division Manager, says while investment in resource recovery facilities is critical, so too is streamlining operations at less glamorous but equally important waste transfer stations.

Being entrusted with the waste management of Victoria’s capital city, and the second largest in the country, highlights the scope and scale of Citywide’s operations. It similarly underscores the importance of finding the right equipment supplier.

Travis says to manage this scale, Citywide and Wastech Engineering developed a symbiotic relationship.

“Citywide and Wastech have worked together in many capacities over the years, with Wastech providing ongoing equipment maintenance and support at our transfer station and working with us in waste and recycling process innovation,” Travis says.

“In the most recent instance, we informed Wastech that we needed new waste transfer trailers to boost operations, and were directed to its Clearline range.”

Travis, who has worked in the waste industry for more than 30 years, says the Citywide Transfer Station and Resource Recovery Centre is the largest of its kind in Victoria, and one of the five largest in Australia.

“Located in West Melbourne, the centre provides waste management services to various local government and commercial clients, meaning effective transport arrangements are key,” Travis says.

“We process multiple waste streams at the facility, largely consisting of municipal waste, residential, commercial and industrial waste and multiple recycling streams such as paper, cardboard, steel and organics.”

According to Sustainability Victoria, over 12.8 million tonnes of waste was managed by the state’s waste and resource recovery system in 2017. In the same year, City of Melbourne residents generated 40,000 tonnes.

To keep up with accelerating service demands, Travis says Citywide recently developed and implemented an operational efficiency plan in order to lift productivity and payloads.

“With ever-increasing volumes of waste generated in and around Melbourne’s CBD – that needs to be processed through the Citywide transfer station – we needed to boost efficiency and invest in new operational and transport equipment,” Travis says.

“One facet of the plan was engaging Wastech for a new range of Clearline Waste Transfer Trailers, with an operational model of owner drivers and a drop and go system for productivity.”

Citywide already owned a number of Clearline trailers, but wanted to upgrade to the newer model. Travis says his previous experiences with Wastech made him confident the new trailer model would meet expectations and application requirements.

The Clearline Waste Transfer Trailer’s rolled wall body design provides durability and integral strength, which Travis says is critical to withstanding the high piercing forces present during compaction of industrial and commercial waste.

The trailer also incorporates the use of high-tensile steel plate in the body to reduce tare weight and increase payloads.

Citywide uses the Clearline trailers to transport waste from its central transfer station in West Melbourne to various landfill sites across the city.

“The Clearline’s smooth internal design, and hydraulic eject blade, safely and efficiently push the waste load out of the body at landfill,” Travis says.

“The full eject feature reduces each load by 20 minutes, equating to one extra load per shift.”

According to Travis, the Clearline trailers are fitted with Elphinstone weighing systems that provide 99 per cent weight accuracy. He adds that as the trailers are mass managed, the weighing systems can be used to full effect.

“The trailers have also reduced volumes at the transfer station, which makes the customer onsite experience quick and easy,” he says.

Wastech’s transfer trailers feature full cab controls to facilitate operator friendly conditions and heightened safety, as operators aren’t required to exit the vehicle when unloading.

“The previous Clearline Waste Transfer Trailer design was great, and worked well under harsh conditions, but the rear doors and hydraulic ejection of the new model really lifts ease of operations,” Travis says.

“As the last piece of Citywide’s operational efficiency plan, the delivery of Wastech’s trailers significantly increased our transfer station operations.”

Handling gold: Kerfab

Ryan Hoban, Kerfab Marketing Manager, talks to Waste Management Review about the company’s new range of waste industry-specific-wheel loader attachments.

Green waste is regularly called black gold – black because it turns dark when fully decomposed, and gold because of its untapped reuse potential.

Green waste presents a number of handling challenges and as such, is often perceived as too difficult to work with, according Ryan Hoban, Kerfab Marketing Manager.

Ryan adds that green waste’s perceived unviability is one reason the material’s potential remains untapped.

“Green waste is biodegradable, and often comes in the form of garden or park waste like grass, tree cuttings, branches and hedge trimmings, as well as domestic and commercial timber waste,” Ryan says.

“It is wet and heavy, arrives as a mass of varied particle sizes and is ultimately very cumbersome to shift.”

According to Ryan, all waste streams present a unique set of challenges, which highlights the need for specialised equipment.

After years building custom bespoke attachments for the waste industry, materials handling equipment manufacturer Kerfab has noticed a gap in the market.

“We’ve conducted countless site visits across Australia and found most facilities were using ill-suited attachments originally designed for other industries,” Ryan says.

“Most industries aren’t as harsh as the waste sector, and therefore don’t require their attachments to work at the same capacity.”

To correctly handle waste, Ryan says operators require wheel loader attachments designed specifically for their material stream.    

“To tame glass waste for example, high dump buckets are useful as they streamline loading into high-sided trailers,” he says.

“But even then, when buckets are designed simply for general use applications, waste operators are likely to run into challenges.”

Ryan says that after extensive research, it became clear the waste industry needed its own range of prefabricated, purpose-built attachments.

“We developed the WastePro range in response to an evergrowing but demanding industry, where productivity is critical and downtime must be prevented at all costs,”  Ryan says.

“The WastePro range is the only set of attachments in Australia designed solely for the unique demands of waste management companies.”

Ryan says the WastePro range enables efficient procurement and removes the necessity of custom builds. He adds that in addition to green waste, the WastePro range features attachments suitable for all waste stream including glass, cardboard and construction and demolition.

“Kerfab is committed to customer service and working in collaboration with our clients. However, it is not uncommon for an operator to require quick and easy access to attachments,” he explains.

“We hope to facilitate this through our new WastePro range.”

Ryan says because general use attachments aren’t designed to handle waste conditions, they can decrease the effectiveness of wheel loaders and the lifecycle of buckets, which leads to premature wear and increased downtime.

“From green and general waste to plastic recyclables, Kerfab has designed multiple variants of our attachments to help maximise uptime and increase equipment life,” he says.

The new range consists of eight separate bucket and grapple attachments, with different models available depending on an operator’s specific material stream.   

“A bucket used to move large amounts of paper needs different functionality design to one working with abrasive material such as crushed glass, and Kerfab has designed the WastePro Range around that fact,”  Ryan says.

According to Ryan, Kerfab paid specific attention to durability during the WastePro design phase.

“More moving parts means there is a greater chance for breakdowns, which is why it’s so important for grapples and high dump buckets be built for purpose,” Ryan says.

“We have also developed heavier duty cylinders to cope with the immense pressure required to repeatedly operate a fully loaded high dump bucket.”

Unlike Kerfab’s standard line, the WastePro Range is manufactured using Hardox, a wear-and-abrasion resistant steel.

“These attachments are designed to increase efficiency, longevity and maximise return on investment,” Ryan says.

“We know how important it is for companies to have minimal downtime, so our attachments are designed to limit this, and subsequently drive productivity.”

Ryan says Kerfab’s after-sales service BackUp+ offers another line of defence for the range. He adds that Kerfab has a network of engineers and fabricators in every major city in Australia.

“They are in place and ready to assist in routine maintenance, such as replacing cutting edges and wear plates, complex fixes and warranty claims.

“This ensures that any attachment related issue will be dealt with quickly to minimise downtime. However, since Kerfab attachments have a less than one per cent failure rate, this scenario is unlikely,” Ryan says.

The WastePro range has recently undergone final testing, with buckets and grapples already in use at waste companies and councils across the country.

“Kerfab will officially launch the range at the Australasian Waste and Recycling Expo in October,” Ryan says.

Tracing every last drop: Cookers Bulk Oil

Cookers Bulk Oil is helping the food services sector transition to a circular economy through a business model centred on managing the entire life of oil and traceability.

Traceability is a prominent concept across the waste and resource recovery sector as multiple players in the supply chain are tasked with looking after the movement of waste.

The same concept is just as important in Australia’s food sector with certifications that ensure products and services gain a tick of approval for best practice. Minimising environmental risks is central to providing customers with such a service.

With tens of thousands of eating establishments throughout Australia – all of which use cooking oil of one form or another – it is an issue that bulk oil specialist Cookers Bulk knows all too well.

When it comes to sustainability, traceability and how vegetable oil can affect its surrounds, the company has processes in place aimed at keeping the environment free from any negative outcomes caused by vegetable oils.

National quality and safety manager for the company Hari Srinivas says product traceability is a universally applicable concept.

He says this is why Cookers has rigid standards when it comes to sourcing its vegetable oil supplies.

“To deal with Cookers you need to be an approved supplier, which means we look and see what sort of practices and standards you are following,” Hari explains.

“Suppliers need to meet minimum standards and it means we don’t go to any supplier who hasn’t got a certification/traceability system in place that is not internationally recognised.”

He cites the Global Food Safety Initiative (GFSI) a private organisation established and managed by the Consumer Goods Forum in Belgium. It maintains a scheme to benchmark food safety standards for manufacturers.

Certification can be achieved through a successful third-party audit by schemes recognised by the GFSI including the British Retail Consortium (BRC) Global Standard for Food Safety Issue 8, IFS Food Version 6 and SQF Safe Quality Food Code 8th Edition, to name a few.

“Without those types of certification we don’t even entertain any supplier,” Hari says.

“We are stringent with our suppliers. If you look into the way the industry is going now, the majority of the supply chains are going through some sort of certification system, including HACCP. These sorts of certifications are one of the core fundamentals of traceability.”

Hari says he is proud that the company has yet to have any of its products recalled. He puts it down to not only the standards it sets, but also compliant suppliers, and their own end-users as well.

Every year, Cookers performs an exercise where they have a mock recall, which involves checking its suppliers’ traceability to make sure they have the correct systems in place and that they are working. This is because he knows that if there ever is a recall, they need to know where every drop of oil they have distributed has ended up.

The good news for end-users is that if that does happen, Cookers will be able to trace the batch number and know where the offending product
is very quickly through its centralised system.

Traceability is also key when it comes to dealing with customers in case things go wrong once the oil has been distributed. Cookers make sure its customers also comply with standards and regulations, too as it’s important the company ensures its customers are getting the product they paid for, according to specifications.

“We are audited every year, and our auditor reviews how long it takes to check something and what is the level of accuracy of our traceability,” Hari says.

“If we have an issue, we can compare it with the same batch delivered nationally to different customers. We can get a sample and test it with the same batches from other customers.”

Cookers’ circular economy solution ensures that the customers who procure its fresh oil are also its used oil collection customers.

Within this setup, Cookers also run a fleet of vehicles, including stainless steel trucks delivering fresh cooking oil and blue vehicles picking up the used product.

Not only do they pick it up, but the company provides storage equipment used on-site by the customer and facilitates the management of the entire life of the oil.   

“Once they use the oil, we provide the equipment to transfer the used oil product into our blue tankers, which collect it at regular intervals,” Hari says.

“We get the oil back and we have got mechanisms to handle the oil in such a way it can go into biodiesel production.

“It means that with every drop of oil we sell, we make sure not a single drop goes into the drain.”

Taking this a step further, Cookers can measure the amount of oil collected and ensure it is the same as that delivered.

“We do all the calculations, so if there are any big variations we will go and speak to the customer to see if there is anything wrong and find out whether we can help with oil management.”

He says another reason to use a company like Cookers Bulk Oil is that due to its tanker delivery method, no empty oil tins head to local landfill. If a customer needed 100 litres of oil per week, that would usually consist of five 20-litre drums which may end up in landfill. With Cookers’ tankers, the drums are redundant.

Importantly, Hari says most of the oil is Australian sourced and more than 90 per cent refined locally.

“For example, the canola oil we sell is 100 per cent Australian.

“Other oils, depending on the cropping situation, are imported in crude form from reputable suppliers who have proper certifications in place – usually from Argentina and European countries.”

Landfill loading: Caterpillar

Caterpillar Asia Pacific explains how differential locks and Cat Connect technology can increase landfill operation efficiency.

Not all landfill sites are the same, with many posing unique and harsh environmental challenges for operators. Land is often unlevel, with small space for movement and barriers to reach cells.

In these environments, managing multiple seemingly competing requirements such as maximising operational efficiency, economic viability and worker safety, can be a challenge.

Ayden Piri, Caterpillar (Cat) Asia Pacific Industry Specialist Account Manager, says landfill operators require reliable and efficient machinery to facilitate safe site management and consistent operations.

He says Cat is uniquely positioned to understand machinery requirements relevant to the waste industry, with over 40 years experience providing for the sector in multiple application modes.

According to Ayden, Cat M Series waste handling wheel loaders are popular with landfill operators due to their heavy-duty handling capacity.

“Cat’s waste handling wheel loaders deliver sustainable productivity, fuel efficiency, ease of serviceability, ergonomics and operator comfort,” Ayden says.

“These environmentally-friendly front end loader machines apply proven technology systematically and strategically, to meet our customer’s high expectations.”

With a global network of 172 dealers, factories in 30 countries and more than 10,000 Cat and dealer employees in Australia and New Zealand, the extensive reach ensures CAT is able to draw on a network of experts to solve its customers’ challenges.

Ayden says M series 950- and 972-metre models have a standard front axle differential lock, which is manually activated by a switch on the cab floor.

The fully automatic front and rear axle differential locks work by measuring differences in axle speeds and require no operator intervention to activate.

“These disc-type differential locks will reduce tyre scuffing compared to other traction aids, further reducing operating costs for customers,” Ayden says.

“The proven Z-bar linkage combines efficiency with great visibility to the tool, resulting in excellent penetration into the pile, high breakout forces and superior production capabilities.”

M Series’ next generation ride control works as a shock absorber, which Ayden says improves ride quality and smoothness over the rough surfaces often found in transfer stations.

“When paired with the Fusion coupler, from a loaded high-dump bucket to a fork to move material, the ride control system provides reduced cycle times, better productivity and a smoother, more comfortable ride for the operator,” he adds.

M Series wheel loaders are equipped with Cat Connect technology, which allows operators to monitor, manage and enhance job site operations.

“Cat Connect facilitates easier service access, with the legacy one-piece hood, centralised service centre’s, windshield cleaning platform and harness tie-off,” Ayden explains.

“Optional purpose-built guarding is also available to help protect your machine from the harsh environments common in waste applications.”

The wheel loader’s machine guarding protects the unit’s major components and systems, facilitating reliable durability.

“Wear in waste handling applications is severe and can drastically cut down a machine’s life,” Ayden says.

“All Cat waste handling machines are protected in key impact areas, including undercarriages, radiators, axles and cabs.”

According to Ayden, the M Series medium wheel loader is 10 per cent more fuel efficient than the industry-leading K Series, and up to 25 per cent more fuel efficient than the H Series.

The updated Caterpillar powershift transmission, with a lock-up clutch torque converter, is standard on all M Series wheel loaders.

“The new torque converters have been matched with engine power and hydraulics to improve performance and fuel efficiency, while also managing the pile or loading trucks,” he says.

“The rugged transmission also has a new split-flow oil system, which uses multi-viscosity oil to reduce parasitics and improve fuel economy.”

Ayden says the M Series hydraulic system has recently undergone significant design changes.

“The main hydraulic valve is now a mono-block with an integrated ride control section,” Ayden says.

“The mono-block design also reduces weight, has forty per cent fewer leak points and is common across all M Series models.”

On 950- and 972-metre models, auxiliary hydraulic functions can be added at the factory or in the field, with the addition of a second remote valve.

“A new thermal bypass valve has also been added to improve hydraulic system warm-up,” Ayden says.

Paddles and packaging: Wastech Engineering

Wastech Engineering’s Jeff Goodwin explains how the ATRITOR Turbo Separator can help businesses achieve a food waste recovery rate of 99 per cent.

Growing populations and an associated increase in food consumption is accelerating the organic waste problem in Australia and around the world.

As reported by Waste Management Review in June, many Australian businesses are hesitant to engage in the source separation of food waste.

This is due to a limited number of recycling facilities able to process the recovered organics, together with concerns around the ability to recycle packaging.

With the National Packaging Targets are squarely on the waste industry’s agenda, the ability to effectively separate recyclable packaging from its contents is therefore equally important.

Jeff Goodwin, Wastech Engineering’s National Product Manager Projects, says growing issues around food waste generation, paired with rising landfill restrictions and capacity levels, was the driving factor behind a recent addition to Wastech’s product portfolio.

“Working with UK manufacturer ATRITOR, Wastech has added a range of turbo separators for food de-packaging to our product roster,” Jeff says.

“As the exclusive Australian representative for ATRITOR, Wastech can provide customers with a solution offering a typical food waste recovery rate of 99 per cent for both dry and liquid products.”

Jeff says the high recovery rate makes the Turbo Separator ideally suited for use in product destruction units.

The Turbo Separator range comprises four models designed and engineered to efficiently remove a wide range of products from their packaging.

“Wastech’s distribution range includes the TS1260, TS2096, TS3096 and TS42120 models, with a material dependant separation rate ranging from 600 kilograms an hour to 20,000 kilograms an hour,” Jeff says.

According to Jeff, the equipment ideal for separating out-of-date, out-of-specification or mislabelled products.

“Historically, expired and mislabelled food products were consigned to landfill due to the difficulty of extracting organics from packaging,” Jeff says.

“With the ATRITOR Turbo Separator we can begin shifting that practice.”

Jeff says the Turbo Separator is sufficiently flexible and can de-package a range of products and packaging materials including supermarket waste, tin cans, polymer bottles and soft packaging.

“Additionally, the Turbo Separator is equally at home separating gypsum from the backing paper in plasterboard,” Jeff says.

“The recovered gypsum can be used in agriculture or re-used in plasterboard manufacturing, while the recovered paper can be further recycled.”

Jeff says the Turbo Separator also works for blister packs, sachets, pouches, paper bags, aluminium cans, plastic bottles, plastic drums and TetraPak.

“The only unsuitable application is glass containers or bottles, as the glass shatters and the shards will contaminate the organics,” he explains.

The Turbo Separator combines centrifugal forces, self-generated airflow and mechanical processes to remove organic material from packaging.

Jeff says this allows the recovered materials to be recycled or disposed of correctly.

Packaged materials are fed by an infeed conveyor into the separation chamber, where a number of rotating paddles open up the packaging.

The force of the paddles then creates a squeezing effect, which separates packaging from its contents without destroying the packaging.

Depending on the material, the recovered organics can then be used for animal feed, nutrient-rich compost or anaerobic digestion.

Wastech can supply the Turbo Separator as a complete package, with an infeed hopper and conveyor, separation chamber and outfeed conveyors.

The separator is also delivered with a maintenance access platform and control cabinet.

“The Turbo Separator’s rugged and durable construction, coupled with high product separation rates and economy of operation, is an ideal proposition for all de-packaging applications.”
