As the exclusive Australian distributor of Flexus Balasystem’s, Wastech Engineering is working to optimise sustainable landfill management.
With the problem of bulky waste processing on council agendas across the country, Neil Bone of Wastech Engineering outlines a 50-tonne packing force solution.
With the installation of optical sorting equipment, a recent MRF upgrade from Wastech Engineering saw capture rates increase by 30 per cent.
Manufactured in Denmark and highly regarded for their design and quality, Bramidan Balers are globally recognised for delivering efficient waste management solutions.
Available in Australia exclusively through Wastech Engineering, Bramidan Balers are capable of compacting a wide range of materials including cardboard, plastic, e-waste and metals.
With a broad choice of Bramidan Baler models available, the crushers are ideal for businesses with a wide range of waste volumes, from small retail outlets to high capacity waste transfer stations.
For larger demands, Wastech offer the X25, which is equipped with cross cylinders to give operators stable compression and superior press force. Combined with a long stroke, a high bale weight can be achieved.
The cardboard and plastic baler is designed with easy servicing in mind, with the hydraulic unit mounted below the control panel on the side of the machine.
For service users with smaller amounts of waste, but who still need a machine to handle bulky materials, Wastech suggests the B5 W baler.
The machine is characterised by a wide filling opening of one metre, which is an advantage when handling larger cardboard boxes. The chamber is equipped with rows of efficient barbs, which keep the material back and ensure optimum filling.
An efficient and silent ejecting system ensures easy handling of the compressed bale, while the strap rolls are simple to replace in front of the machine.

Wastech Engineering’s Neil Bone details the companies multi-pronged approach to innovation in the waste transport space.
With over 27 years’ experience providing transport solutions to the waste and resource recovery sector, Wastech Engineering is committed to solving customer’s problems now more than ever.
Neil Bone, Wastech Engineering Managing Director, says while the current global climate poses a number of challenges, it’s imperative for the waste industry to remain strong and forward focused.
Highlighting the United Nation’s recent call for global governments to recognise waste as an essential service, Neil says Wastech are poised to support sector growth with high-quality and efficient waste transport solutions.
According to Neil, Wastech’s Flexus Balasystem is a streamlined, next-generation approach to waste transport. This is, he adds, despite its lack of wheels or “vehicle” capabilities.
The Flexus Balasystem, which functions like a satellite hub or transfer station, is a complete heavy-duty system for bailing, storing and transporting compressed waste in round bales.
With a processing capacity of up to 30 tonnes per hour, the Flexus unit has a helicopter-style wrapping component, with bale ejection at either side of the machine.
“Finished bales are ejected onto a bale conveyor that holds up to three finished bales at once. These can then be loaded onto standard road and rail trailers for transfer,” Neil says.
“By compressing material before it’s transported, operators stand to save significant time, reduced emissions and increased payloads, with the level of material transported in a single trip multiplied significantly.”
As an all in one system, Neil says the Flexus is cost effective, with a single machine fulfilling all required tasked along the chain. Flexus has a small footprint and low civil costs, with compacted and wrapped bales sealed in modular cells that can be stored on site.
This, Neil says, provides operator flexibility by allowing transport out of peak traffic times.
“Standard road and rail trailers can be used to keep logistics cost down, which eliminates the risk of trailer downtime and provides a competitive logistics environment with low operating expenses. Furthermore, as bales can be transported using any kind of trailer, back freight can be easily sourced.
“Since the waste is baled, the trailer remains clean and freight can be brought back to the hub,” Neil says.
The system is available in three different models and is suitable for a variety of waste types including municipal solid waste, solid recovered fuel and recyclables.
“All of our Flexus bailing systems are tough and high-powered, providing clients many years of reliable service,” Neil says.
Wastech Engineering has released its newest screening technology from its partner, the CP Group – the CP Auger Screen.
The anti-wrapping, non-blinding screen was developed specifically for materials recovery facilities.
The trademark CP Auger Screen sizes material by using a series of cantilevered augers that do not wrap or jam due to their corkscrewing motion.
Any material that could wrap, such as strapping, hoses or plastic film, are released off the end of the auger.
Its low-wear augers are made from abrasion-resistant steel, making them durable while requiring little to no maintenance.
The CP Auger Screen can be used in various recycling applications, including commingled, municipal solid waste, construction and demolition and commercial and industrial wastes.
The largest model can handle 30 tonnes per hour of inbound single stream material, 55 tonnes per hour of commercial and 70 tonnes per hour for construction and demolition material.
The machine is unique compared to traditional disc screens as the auger rotors act like a corkscrew, conveying any stringy materials over the side. The cantilevered augers convey large flat materials over, while fines and flexible fibre go through the augers or out the side of the screen.

The Atritor Turbo Separator was developed to separate products from their packaging, releasing them for recycling or disposal.
Available through Australian distributor Wastech Engineering, the Turbo Separator enables up to 99 per cent of dry or liquid products to be separated from their packaging with minimal contamination. This allows the contents to be used for compost, anaerobic digestion or animal feedstock.
The Turbo Separator can be manufactured in a range of throughputs up to 20 tonnes per hour.
Additionally, the process is so efficient that it leaves packaging relatively intact and clean to facilitate downstream recycling. According to Wastech, when compared to other methods of packaging separation, the Turbo Separator achieves higher separation efficiencies with lower power consumption, resulting in reduced operating costs.
The Turbo Separator is ideal for separating out of specification, out-of-date and mislabelled products from a variety of packaging, including cans, plastic bottles and boxes. The diverse range of applications includes the separation of paper from gypsum in plasterboard, general foodstuffs from their packaging and liquids from their containers.
It is available complete with in-feed and out-feed conveyors and liquid transfer pumps. The Turbo Separator, with its durable construction and adjustable paddles, enables the separation of a wide variety of products.
Each Turbo Separator installation can be configured to suit multiple applications and a variable shaft speed enables enhanced separation efficiency. The machine is available in mild steel and stainless steel to suit the application.
Wastech Engineering’s Scott Foulds highlights the latest technologies to support a variety of materials recovery facilities.
When Freshkills Landfill in Staten Island, New York, one of the largest landfills in the world, closed at the end of 2001, it forced the City of New York to explore alternative waste management options.
One option mooted in the early 2000s to fill the gap was a materials recovery facility (MRF). According to a research paper published by the Department of Earth and Environmental Engineering, a 150-ton-per-hour facility could handle all of New York City’s recyclables. The operations within the MRF were proposed to be as automated as possible, increasing speed of operation, reducing costs and improving material recovery.
More than a decade on, New York City and other cities across the globe have embraced best practice, with the next generation of screens, optical sorters and air separation technology providing an end-to-end solution.
In leveraging more than 25 years’ experience supplying waste and recycling equipment, Wastech Engineering has been offering technologies to allow MRFs to sort and separate a wide range of waste streams.
Wastech’s commingled recycling screen range features the latest in design and engineering from their US partner The CP Group. From the proprietary cam-disc style CP Screen (polishing screen) to the OCC Screen and Auger Screens, the CP Group continues to set the pace for screening technology in kerbside recycling.
Scott Foulds, Operations Manager at Wastech, says the company’s range of screens provide full flexibility in MRF design for sorting and separating of various commodities.
“The flexibility of the MRF design, including which streams are captured, is ultimately designed around the outputs the customer wants for the markets they will sell into,” Scott explains.
“The CP Group in the US has implemented an extensive research and development program over the past 10 years to develop their screens to minimise wrapping and increase efficiency in seperation.”
Scott says the OCC Screen is an essential machine for any MRF. The screen effectively separates old corrugated cardboard (OCC) from other mixed fibre, containers and debris. Characterised by its low maintenance and wrapping design, the screen drops all material under 300 millimetres through the screen for further sorting.
“99 per cent of what goes over the OCC Screen will be clean cardboard with a very high purity rate so you don’t need quality control,” Scott says.
He says the steel discs and shafts have been designed for reduced wrapping, with a lifespan of around 15-plus years due to their robust construction and quality design.
The glass breaker screen is the next step in the process which breaks and separates glass and fines down to a 50-millimetre-minus product. The glass is removed early in the sorting process to protect the longevity of the equipment upstream.
Air separation technology can then remove light materials from glass such as small fibre, organics and plastics, with Wastech offering a host of systems through The CP Group or Impact Air.
The NewScreen is ideal for MRFs processing higher volumes that want to capture old newsprint. It is designed to automatically separate large fibre from mixed paper, containers and debris.
“If you’re operating a smaller MRF, then the CP Screen could recover all the fibre. But it does come down to what markets the customer has to sell their products into. If they’ve got a market for mixed paper, newsprint and cardboard, it’s better to separate those items, especially if the end user is getting good value for money,” Scott explains.
The CP Screen ensures a clean stream of paper by eliminating residues such as small fibres and organic material by dropping this out through the screen. The paper (2D material) goes over the top of the screen and the containers (3D material) go off the back of the screen. The CP rubber disc screens can be adjusted for speed and inclination, allowing it to be varied from 30 to 40 degrees, which help improve the efficiency and quality of the screen’s functionality.
Scott says the CP Screen has numerous advantages over other separators, namely the quantity of throughput and quality of separation.
In continuing to expand its offering to Australian MRF operators, Wastech launched the CP Auger Screen in 2018 – which enables accurate separation of newsprint and large fibres from the material stream early in the separation process. This is particularly useful in higher volume MRFs.
While robotics is largely an emerging technology, Scott says a variety of optical sorters can be used instead to sort fibre and containers and achieve high throughput, capture rates and quality outputs.
“As an alternative to robotics, we’ve come up with a different design in our optical sorting range where we use a single line optical sorter on the container line.
“All the containers pass through an optical sorting head which determines the container type, whether it be aluminium, PET, HDPE or liquid paperboard.”
The container is then ejected into the designated hopper as it passes down the conveyor line. Scott says all of Wastech’s products are backed up by its 24-hour Service Centre, with 15 service vehicles on the road nationally.
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.”
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.”
