Moving with the times: Tutt Bryant and Bomag

Queensland’s North West Services has been using Bomag compactors for more than 20 years, with a number of key factors contributing to the long-standing partnership.

With an ever-increasing emphasis on source separation, waste handling and landfill diversion, today’s waste facilities are well regarded.

This experience has led to a better understanding of machine performance and capacity, allowing waste operators to respond to all conditions.

In the Whitsunday towns of Proserpine and Bowen, North West Services (NWS) remains committed to best practice.

NWS began working with the Whitsunday Shire Council at Cannonvale Transfer Station and Kelsey Creek landfill sites in 1998. Since 2004, the company has remained the contractor for management and operation of the council landfills. Husband and wife team Ray and Noleen established the business together and Noleen has been a director for more than 20 years.

Luke Purvis, now a managing director, assumed the role after his father fell ill in 2014. Having worked very closely in all aspects of the business, including financial and customer management, Luke provides an honest, knowledgeable and proactive approach to his duties.

As part of its ongoing commitment to high standard landfill management, NWS has been operating Bomag compactors for more than 20 years. Available through Australian supplier Tutt Bryant Limited, Bomag has remained at the forefront of compaction technology for decades, continually refining its various models to suit the modern landfill.

He says that NWS participates in all aspects of management. This includes unlined and lined cells, storm water system installation, batter rehabilitation and maintenance, supervision of waste receival, and handling all contract environmental standards.

Luke says that NWS has investigated the comparable operating capabilities of other manufacturers’ landfill compactors in the same class. After rigorous testing and compaction analysis, he says NWS was assured that Bomag landfill compactors feature superior advantages on all levels, including both on-the-ground and operational.

“Low servicing costs, long machine life without major component failure and increased operator comfort are all important factors that make Bomag continue to stand out for us,” Luke says.

Luke adds that the machines also have reduced noise and emissions.

NWS own and operate landfill equipment for site management and fully serviced long and short-term dry hire, covering local government and commercial waste operations. The company maintain a fleet of around 30 pieces of plant with additional service and haulage vehicles.

Over the past two decades, NWS has gradually increased their fleet to meet stakeholder requests while replacing units to meet growing performance standards.

When it comes to the performance of Bomag compactors, Luke explains that compaction teeth are warranted standard at 10,000 hours – a key factor aiding long service life.

Reliability and efficiency in mechanical performance covers daily auto lubrication and service check points, self-cleaning wheels with adjustable wire cutters. Economical fuel consumption is supported by a load sensing engine fuel system and hydrostatic drive.

As operator comfort is a prominent consideration, Tutt Bryant landfill compactors feature a climate control cabin, heated seat, filtered air supply, joystick and malfunction warning system. The telematic system provides current machine diagnostics and location.

NWS has many contracts with customers in local government and commercial waste operations and Tutt Bryant Equipment forms an important part of that operation. Luke says NWS supplies fully serviced dry hire waste compaction and handling equipment packages in Queensland and Victoria.

“These are managed by NWS mobile servicing units, additionally also backed by Tutt Bryant Equipment servicing and spare parts departments,” Luke says.

Luke says the NWS mobile servicing units offer the proven ability to maintain their machinery to meet the usage required under landfill conditions. This usually requires an all year, seven day a week operation/service. NWS is an authorised agent for the servicing and maintenance of all their units.

In its workshop, NWS stocks major spare parts, including full power train componentry for the Bomag Landfill Compactor. This ensures 100 per cent availability of compaction machinery on-site at all times.

Refurbished exchange wheels and caps can be fitted to NWS’ 30 plus tonne compactors in a day to maintain compaction. They also position some on-site stock holdings of consumables and parts often required.

Luke says that NWS believes that extensive knowledge of the machines, backed by warranty through Tutt Bryant and Bomag, ensures NWS customers are provided with the high standard of service they’ve come to expect.

“NWS provides skill and expertise in our industry by keeping up to date with industry changes and assessing and using opportunities to build efficient, effective practices into their services which may benefit our customers,” Luke explains.

“Our experience with Bomag compactors and Tutt Bryant Equipment is that they both have proven to be extremely reliable and we have had no hesitation in purchasing further units when the need arises.”

The value of waste: CDE

Waste Management Review explores how CDE wet processing technology is supporting Melbourne-based recycling company Repurpose It to reduce a reliance on landfills.

Operating from its 150-acre rehabilitated quarry site in Epping, Repurpose It has an ambitious vision to achieve a 100 per cent recycling rate across its complete waste portfolio.

Likewise, it aims to ensure zero unnecessary waste is destined for landfill. This vision is perfectly aligned with CDE, an industry-leading manufacturer of wet processing technologies, whose ethos is unlock a “New World of Resource”.

To achieve its aspirational environmental aims, George Hatzimanolis, CEO of Repurpose It, turned to CDE to design and engineer a state-of-the-art solution to transform construction, demolition and excavation (CD&E) waste, along with contaminated railway ballast, into in-spec sand and aggregate products that meet the requirements of the local building industry.

George says Repurpose It is committed to recycling products at the end of their lifecycle to transform them into materials that will be used at the beginning of a new lifecycle. These include waste previously considered difficult to process, he adds.

“To achieve 100 per cent recycling of construction and demolition waste, we required a wet processing solution that could efficiently separate and wash every available fraction of material in the feed,” George says.

CDE’s solution, a first-of-its-kind in Australia, incorporates a selection of modular elements that work in synergy to produce best-in-class results, including an AggMax logwasher, the latest in the CDE patented Infinity screening range, a ProGrade H2-60 screen, an EvoWash sand classification and dewatering system, conveyors, a decanter centrifuge and AquaCycle thickener.

Every day, the plant processes up to 150 tonnes an hour of CD&E waste into high-value construction products, which would have otherwise been bound for landfill.

CDE’s customised solution processes CD&E waste and rinses and grades it to make six in-spec products, four aggregates (4-10, 10-20, 20-150, 50-100 oversize) and two sands (0-2 and 0-4).

Daniel Webber, CDE Australasia Regional Manager, says entrepreneurial companies such as Repurpose It have identified that the Sydney Basin and Melbourne are running out of sand.

“The depletion of local sand reserves means that construction and concrete companies now have to transport sand via road from further away or turn increasingly to the production of manufactured sands from hard rock deposits which are more expensive to mine and more hard-wearing on plant and equipment,” Daniel explains.

“This is where CD&E waste processing plants come into their own. They accept waste feed from metropolitan areas and clean it to repurpose it back into the local construction market.”

At the same time, Daniel says there is limited room available for tailing ponds.   

“CDE’s world-leading water recovery and tailings treatment technologies are used to make dry tailings that can be transformed into marketable products themselves,” he adds.

Hand-in-hand with protecting the planet’s finite natural resources is protecting the Earth itself and minimising the carbon emissions associated with the industry.

Vitally, the innovative wet processing plant commissioned for Repurpose It by CDE enables the waste-to-resource business to reduce its carbon dioxide output by more than 84,000 tonnes per year, based on processing 500,000 tonnes of feed material.

“Our investment demonstrates our commitment to reducing the construction industry’s reliance on extractive resources and underpins our company values of creating value from waste,” George says.

An all-in-one lubrication solution for recycling plants

All recycling plants, whether they deal with metal, glass or pulp and paper processing, have one thing in common: they all need quality lubricants to keep their systems running reliably and efficiently.

Understanding the importance of a comprehensive lubrication solution for recycling plants, CBC Australia has partnered with Viva Energy to offer a wide range of premium Shell lubricants to customers across Australia.

CBC’s National Product Manager for Lubricants, Steve Keown, says easy access to Shell’s comprehensive portfolio of oils and greases for hydraulic parts, gears, heavy duty diesel engines and turbines is an attractive offer for their customers, especially given their global strength.

“It is an attractive option for our customers to work with a single brand that offers such an extensive product portfolio than to work with multiple brands. It reduces the number of products they need on-site and makes managing their lubrication store so much easier,” says Keown.

One issue that Plant Managers and Original Equipment Manufacturers (OEMs) currently face is having to deal with multiple brands of lubricants that are specified for each piece of equipment.

This can lead to confusion on their part, particularly in a scenario where there’s been a change of staff or if the inventory is not managed properly.

“One site we surveyed had 14 brands of lubricants on-site. Some products had been there for more than a decade and most of the products were well past their shelf life,” Keown says.

As part of its offering, CBC appoints local teams to work closely with their customers to assess their current lubricant scenario and provides recommendations on how to rationalise the number of different products that they are using.

They can also complete the necessary testing to ensure that all lubricants in use meet the relevant industry standards. Shell’s LubeAnalyst service is a lubricant health check available to customers who want their oil samples tested to monitor equipment and lubricant health.

CBC’s services include cataloguing the current lubrication store to present a new, high quality lubrication program. The team can also assist with recommending solutions to better handle lubricant deliveries and provide the necessary recovery equipment and spill kits.

If commissioned by customers, CBC can further carry out a plant survey to identify all areas for improvement, such as the use of wrong or duplicate products.

In addition, the CBC engineering team can provide preventative maintenance programs. These may include scheduled lubricant sampling, oil and vibration analysis and mapping normal levels to identify red flags before any major failure occurs.

“This could save the customer from minor inconveniences as well as significant downtime with major component failures. Some of these plants use bespoke parts that aren’t sitting on a shelf somewhere. Should something unexpected occur, the team can conduct a root cause analysis,” he adds.

Viva Energy Lubrication Expert, Paul Smallacombe, explains why it’s particularly important for recycling plants to use premium lubrication products.

“Waste recycling systems often place excessive load and temperature stress on the lubricants used. Using quality lubricants that are designed for the specific applications helps reduce the operating temperatures and extend the machine’s life.

“A prime example of this is Shell Tellus S2 MX 68 hydraulic oil that resists breakdown under heat or mechanical stress and helps in preventing damaging deposit formation, therefore extending the operating life of machinery,” he explains.

Another objective in planning the best lubrication program for a recycling plant, Smallacombe says, is to extend oil drain intervals.

“Operating costs are always at the top of a plant manager’s mind. Using lubricants with longer service life ensures less downtime and therefore more efficient operation. For example, one of our customers was able to double their oil drain interval after we introduced them to the correct Shell product.”

To help customers identify the most suitable lubricants, Smallacombe and the Viva energy technical Team work closely with CBC and their customers to share their expertise.

“There are a number of less reputable lubricants in the market that do not meet the industry standards and have not received the necessary approvals. But their advertisements use terminologies that can be misleading for customers. This creates the additional risk for a customer to lose their warranty on certain machinery if they use an unapproved product,” he said.

“Through our oil testing services, we can establish how equipment is operating with a certain lubricant. If necessary, we can trial a higher tier product for the customer and report the results after a second analysis.”

TSA and ARRB trial crumb rubber asphalt on busy Melbourne road

Crumb rubber asphalt is being laid on a busy Melbourne road as part of a new trial funded by Tyre Stewardship Australia (TSA), the Australian Road Research Board (ARRB) and the Victorian Department of Transport.

While already a proven technology on country roads, the project aims to increase opportunities to use crumb rubber asphalt on highly trafficked roads.

The asphalt will be laid on a 1.4 kilometre section of East Boundary Rd in Bentleigh East, with four seperate crumb rubber mixes and two asphalt control sections. The equivalent of 1600 car tyres will be used.

The trial is in line with the Victorian Government’s Recycled First policy, which aims to increase the use of recycled materials in construction projects, TSA CEO Lina Goodman explained.

“Australia generates the equivalent of 56 million used car tyres every year. Around 30 per cent of those end up in landfill or are stockpiled,” she said.

“Finding innovative and sustainable ways of using old tyres is vital, and crumb rubber asphalt roads are the perfect solution to a waste problem.”

According to ARRB CEO Michael Caltabiano, when added to an asphalt mix, crumb tyre rubber not only assists with the reuse of waste, but adds value to the road structure.

“ARRB’s applied research findings show that crumb rubber asphalt lasts longer, performs better and delivers a better economic outcome for the community,” he said.

Lab and field testing will be conducted at regular intervals, with a final report due by mid 2022.

Cleanaway awarded largest municipal contract in SA history

Cleanaway will provide essential waste services to over 160,000 South Australian residents after it was awarded the largest municipal contract in the state’s history.

The collaborative council contact includes end-to-end waste management services for the City of Port Adelaide Enfield, City of Marion, City of Adelaide and City of Charles Sturt.

According to Cleanaway General Manager Solid Waste Services Conan Hookings, Cleanaway will invest in 30 new staff and over 40 fleet assets to support the contract.

“Our brand-new collection fleet will be equipped with the Cleanaview fleet management system, which provides real-time data on collection services, enabling an online portal for residents to make requests and queries,” he said.

Under the waste services contract, Cleanaway will provide kerbside waste, recycling and organics collections out of its Port Adelaide and Lonsdale depots, while residual waste will be processed at Wingfield Resource Recovery Facility and Inkerman Landfill.

The seven plus three years contract also includes bulk bin, hard waste and street litter collection and processing.

“Our service will be supported by additional education resources to help residents put the right materials in the right bin to reduce contamination and improve recycling outcomes,” Mr Hookings said.

Electric collections vehicles are also set to be trialed in select council areas.

“These zero emissions trucks were rolled out in VIC and WA as early as last year, reducing carbon footprint and noise levels on the road without impacting service levels,” Mr Hookings added.

In welcoming the contact, Marion Mayor Kris Hanna said it demonstrates what can be achieved when councils work together.

“About 43,000 households will benefit in Marion from a greener, more efficient kerbside collection service that increases the focus on our community,” she said.

The new kerbside collection service will begin in Marion and Port Adelaide Enfield 1 May, followed by Adelaide City Council 1 July. Services in Charles Sturt will be rolled out 1 May 2021.

High frequency resources: Astec

Adam Gordon, Astec Australia National Account Manager, talks high-frequency screening efficiencies and a growing waste sector presence. 

With the Victorian Government’s recent $100 million investment in recycling and Infrastructure Australia’s call for a harmonised national waste plan, sector growth is imminent. Add increasing market interest in the use of waste for infrastructure applications and, according to many stakeholders, the future looks bright for domestic reprocessing markets.

While equipment supplier Astec Australia has traditionally focused on the quarrying and mining sectors, Adam Gordon, National Account Manager Aggregate and Mining, says developments in the resource recovery sphere have entrenched the company’s growing interest in “waste as resource.”

“In recent years, our interest in, and equipment offerings for, the waste and recycling industry has increased significantly. And we now have multiple screening options on offer to help operators separate deleterious material from valuable resources,” Adam says.

“Plus, with demand for fine material growing for applications such as glass in roads and crushed rock, and the growing acceptance of reclaimed asphalt pavement, operators need access to the best possible tools for separating fines. That’s a progressive development we want to support.”

One such offering, Adam says, is Astec’s new GT2612V track high-frequency screen. He adds that as the screen is high, rather than multi- frequency, the GT2612V is capable of screening finer and more difficult to manage material.

“Our high-frequency screens offer ideal gradation control for reclaiming fines in dry applications, with all high-frequency screen decks driven by variable-speed hydraulic vibrators for optimal screen efficiency and production,” Adam says.

“Producers save time and money with easy hydraulic screen angle adjustments and our unique rotary tensioning system, which ensures some of the quickest screen media changes in the market.”

The screen works via stratification, with larger size particles rising to the top of the vibrating material bed, while smaller particles sift through voids to the bottom.

“It also works on the probability of separation, as particles that reach apertures are rejected if they’re larger than the opening or passed through if smaller,” Adam says.

“As fines screening is most efficient when machines are configured with a short stroke, high revolutions per minute and steep angle, the GTV2612V can operate at angles up to 43 degrees to operate through the natural angle of material repose.”

Astec’s track-mounted screens, Adam says, are engineered to provide higher production capacities and more efficient sizing when compared to conventional screens.

“Our track-mounted screens combine heavy-duty screens with industry-leading conveyor heights.With easy-to-reach engine controls and grease points for routine service, they facilitate operator ease and process efficiency,” he says.

Adam adds that due to the high-frequency screen inducing vibrations directly into the screen media, operators have reduced maintenance issues and increased production and uptime.

Astec’s new screening addition has a hopper size of 7.2 metres cubed, which Adam says facilitates consistent and high-level processing.

He adds that the GT2612V separates at up to 4200 revolutions per minute.

“Our unique rotary tensioning system also provides quick screen media changes, up to 50 per cent faster than competitive models,” Adam says.

“Easy replacement of each screen section also translates to less downtime for screen changes and increased operational time.”

In addition to selling high-quality equipment, Adam says Astec is committed to providing ongoing support and assistance to all its clients.

“We have a dedicated team of customer service staff who are always ready to provide clients with information about what machinery is best suited to their application,” he says.

Adam says Astec also has a number of business processes, including sound commercial and project management, based on industry standard principles and best practices.

He says that this means that all customer projects are carried out through known project phasing. This comprises appropriate project software to ensure equipment is delivered, installed and commissioned on time and on budget.

Adam adds that Astec stamps all of its equipment with an “Astec Response Promise”. This means equipment purchases are supported by quality maintenance, repairs and spare parts nationwide.

“We believe in our responsibility to ensure our equipment operates effectively and efficiently throughout its life, which fits in nicely with our growing waste industry presence,” he says.

WA defers CDS launch in wake of COVID-19

The Western Australian Government has deferred the launch of its container deposit scheme Containers for Change due to COVID-19 concerns.

Originally planned to launch June 2, Environment Minister Stephen Dawson said the decision to delay the scheme reflects the unprecedented impact of COVID-19 and its expected disruption to refund points.

According to Mr Dawson, the postponement is in accordance with advice from the scheme co-ordinator, WA Return Recycle Renew.

“COVID-19 has resulted in significant global, national and state impacts and there has been disruption across the board for government initiatives and services,” he said.

“The state government, in close consultation with WA Return Recycle Renew and the Department of Water and Environmental Regulation, determined that under the COVID-19 environment we are all faced with, there are too many potential health risks and logistical difficulties to start the scheme on June 2, 2020.”

The state government will review the situation in August 2020 to determine whether the scheme’s new start date will be November 2020 or June 2021.

“Delaying the scheme until after the major impacts of COVID-19 are felt will eliminate the public health concerns such as potential risk of infection from handling containers, as well as over-the-counter refund points contravening social distancing,” Mr Dawson said.

“While it is disappointing to be deferring the scheme, we remain committed to delivering the most diverse and accessible scheme in Australia. We will continue to work together and update the community, operators and suppliers throughout this period of uncertainty.”
