More teeth, more traction and compaction: GCM Enviro

With sustainable landfills representing a critical competent of the waste management ecosystem, GCM Enviro details the importance of high-density compaction. 

Basic supply and demand economics, paired with resource recovery infrastructure shortages and still developing technologies, means sustainable landfill management remains a critical feature of any well-functioning waste management system.

To that end, GCM Enviro, a leading distributor of waste management equipment, is investing heavily in sustainable and efficient landfill compactors.

As the exclusive Australian supplier of Tana landfill compactors, Susie Solbrandt, GCM Marketing, says GCM are well placed to provide high compaction machinery that saves landfill airspace and reduces leachate generation.

This is highlighted by the company’s introduction of Tana’s specialised high-density drums to the Australian market in 2019.

“Tana’s high-density drums can be fitted to all Tana E Series Landfill Compactors, facilitating higher compaction rates via crushing force. The drums improve traction and efficiency, thereby increasing an operator’s ability to compact waste in shorter intervals,” Susie says.

With 14 teeth per 11 rows, compared to the standard Tana BigFoot drum’s 10 teeth per row, the high-density drums provide greater material engagement for each drum rotation.

This Susie says, shreds waste into more uniform sized particles, with 154 crushing feet per drum, compared to a standard drum’s 110 feet.

Susie adds that the new high-density drums produce a compaction capacity of 1150 metres cubed per hour, compared to the standard drum’s 950.

According to Susie, GCM sold a new Tana E520 Landfill Compactor to a major New Zealand waste operator in late 2019. Since running the updated high-density drum, have noticed significant compaction improvements.

Operating one of New Zealand’s largest landfills in North Waikato, Hampton Downs, the company have extensive experience in the design, construction and operation of modern landfills and cleanfills.

Susie says reports from the company show the new high-density drums are low maintenance, with superior climbing efficiency and fuel burn.

She adds that with fewer passes, simplified maintenance and good drivability, Tana E Series Compactors work to save expensive landfill airspace.

“GCM’s philosophy is to maintain constant dialogue between manufacturers and clients to ensure equipment design is governed by market requirements, particularly in the harsh climatic conditions we experience,” Susie says.

“Ultimately, our objective is to enable customers to increase revenue with cutting edge technology, allowing them to generate value from waste.”

Sifting rubble: GCM Enviro

As Queensland’s infrastructure pipeline accelerates, Jim Murphy, Lantrak Waste Division Manager, speaks with Waste Management Review about the efficiency effects of heavy-duty separation.

Workers on Queensland’s Gateway Upgrade laid tools down in March 2019, after 15 years and a $1.1 billion spend.

Designed to unlock economic growth through congestion busting, the project saw the motorway jump from four lanes to six.

To manage material movement, the Queensland Government engaged earthmoving and plant hire specialists Lantrak to move and process clean fill.

Annually moving over 10 million cubic metres of clean and structural fill, the Gateway Upgrade isn’t Lantrak’s only landmark construction project venture, having worked on the Snowy Mountains Scheme and the Wonthaggi Desalination Pipeline.

In addition to its earthmoving service, Lantrak operates a waste and recycling facility in Swanbank, Queensland. The facility is licenced to accept C&D, clean fill and low contaminated soil.

Jim Murphy, Lantrak Waste Division Manager, says the facility prioritises investment in high-quality and heavy-duty processing equipment. He adds that this was the key driver behind Lantrak’s recent Terra Select W 80 Windsifter acquisition.

“We needed a new piece of equipment to separate construction and demolition waste after it had been screened and crushed, so we engaged equipment distributor GCM Enviro,” he says.

“As Australia’s exclusive distributor of Terra Select equipment, GCM Enviro was the obvious the choice on the parameters required.”   

The Terra Select W 80 Windsifter is designed to separate heavy from light materials, such as stone from wood or concrete and bricks from timber. It also removes other light materials such as plastic or paper. Jim says the machine’s efficient ability to separate impurities from useable material flows has streamlined Swanbank’s operations.

The Windsifter is equipped with a high continuously adjustable cleaning level, at throughput rates up to 120 cubic metres an hour in certain streams.

“The machine has a unique hopper with dosing roller, which provides closed operations independent of the screening process. This ensures an even infeed of material into the machine,” Jim says.

Material is fed via an upstream feeding conveyor, with equalisation and distribution conducted via a proportioning drum and downstream acceleration belt. A compressed air nozzle then blows under the material, holding light impurities in the air.

“At the end of the acceleration belt the material is blown over the separation gap, before moving to the separation drum,” Jim says.

“The machine is also very flexible, with the ability to fine tune configurations via taps ducts and separate on heavy and light settings.”

According to Jim, the separator hasn’t disappointed, with minimal downtime or blockages. He adds that through constant dialogue between manufacturers and clients, GCM Enviro is able to ensure reliable customer-orientated servicing support.

“If our material intake grows like I think it will, I look forward to maintaining a long-term partnership with GCM Enviro.”

Screening for all occasions: GCM Enviro

Terra Select trommel screens aim to tackle often challenging materials with ease, including wet compost and hard waste such as plastics and foams.

Whether it’s the Terra Select T 30 for small composting sites or the T 60 for high throughput performance, Australian distributor GCM Enviro offers a machine for all occasions.

Popular among smaller composting sites, the T 30 offers flexibility, good accessibility and low operating costs. Service tasks and trommel changes can be performed easily and reliably.

Those after a powerful machine with compact dimensions can look no further than the T 40, with all the technological advantages of the “big machines” transferred into the compact class.

With a screening performance of up to 200 square metres per hour, the Terra Select T 60 is equipped with a 2200 millimetre trommel drum. The high-performance 81-kilowatt motor allows sufficient reserves for star screening decks or windsifter attachments.

The most powerful mobile machine in the Terra Select product range is the T 70, with an ability to handle hard-to-screen materials such as wet compost. The long trommel and its correspondingly wide screening deck is suited to screening all kinds of waste.

Screening two fine screenings in one step is a standout feature of the DT 60. The double trommel screening machines perform a “coarse fine separation” to separate course fractions in the initial screening stages.

GCM Enviro is the sole distributor of Terra Select machinery in Australia.

GCM Enviro: brooklyn bound

Sunshine Groupe Operations Manager Colin Riley tells Waste Management Review how the rise in construction and demolition waste prompted their latest purchase.

With capital injections at a state and federal level, the Australian construction industry is booming.

Capital influx, paired with growing public consciousness around the impacts of waste and the reality of finite resources, has led to an increased number of construction companies seeking sustainable solutions for their construction and demolition waste (C&D).

Located within a 10-kilometre proximity of the Melbourne CBD, Sunshine Groupe’s Brooklyn recycling site has become a hub for the city’s C&D waste.

Operations Manager Colin Riley says C&D is now one of the company’s most commonly received waste streams.

“We are heavily invested in safeguarding the community and the environment through recycling, and as such need effective and accurate equipment to separate heavy impurities from the material we want to process,” Colin says.

“I’ve been working at Sunshine Groupe for over 20 years and the rise in C&D is substantial. A number of challenges come with that given the materials high variability and substantial weight.”

Colin says the scale of the Brooklyn site is what inspired the need for a new for a new piece of mobile sifting equipment.

“We already have lot of fixed processing equipment on site but are dealing with significant space and multiple stockpiles. Transporting waste around the site to access that fixed equipment was becoming unsustainable,” Colin says.

“After consulting with GCM Enviro, we decided to purchase a moveable Terra Select W80 Windsifter four months ago and its really solved that issue for us.”

The Terra Select W80 mobile windsifter separates stones from wood materials, wood from building rubble and impurities from aggregate.

“We depend on cleanly separated feedstock so recycled components can be further processed. Our situation is therefore ideally suited to separation via windsifting,” Colin says.

According to Colin, Sunshine Groupe use the Terra Select windsifter to process roughly 50,000 tonnes of material each day.

“The Terra Select outperforms all other windsifters I’ve used and has far exceeded my expectations,” Colin says.

The sifter can achieve a throughput of up to 120 cubic metres per hour and has an adjustable level of cleaning of up to 95 per cent, with an optimum feed grain size of one to four.

In addition to its own feed hopper, the mobile windsifter also has an integrated metering roller that Colin says enables fast turnaround times.

“The machine has flexible options for feeding material, which we can adjust depending on the specifics of what we are working with at the time,” Colin says.

“It can be adjusted to work either at an angle with a wheeled loader, or at an angle from an upstream screening plant. The dosing roller then evenly feeds the material from the hopper to the windsifter.”

If required, the discharge conveyor of the separator can be fitted with a magnet to remove metals from building rubble, further highlighting its application use for varied waste streams like C&D.

The machine is controlled centrally via a modern display, with all machine components readily accessible due to large maintenance hatches. Additionally, it is driven by its own high-output diesel engine, which supports total mobile function.

“It’s a mobile machine in every sense of the word and can be completely set up and functional within a short space of time for new locations or feedstock changeover. It also has road approval for off-site operations,” Colin says.

In addition to separation, the windsifting process protects other machines and plants by removing heavy debris before later processing stages.

When dealing with stone or concrete for example, sifting removes potentially harmful objects, purifies the material before crushing and leads to a longer shelf life for all machinery involved.

“GCM Enviro really pulled through for us, we told them what we needed, and they delivered on all fronts,” Colin says.

“The servicing and parts department is really on the ball – if we make a spare or extra parts order it arrives the following day.”

Colin says while he hasn’t needed to take them up on the offer yet, GCM Enviro has committed to sending service and maintenance teams downs to Melbourne if any issues arise.

“I’ve been in the industry for over two decades and have seen a lot of equipment, some that works well, some that doesn’t,” Colin says.

“The Terra Select W80 works so well because it takes a lot of different technology types and combines them, really expanding the capabilities of a relatively small machine.”

TANA E Series Landfill Compactors

The TANA E Series compactor was designed to maximise uptime and provide landfill operators with efficiencies to invest in other critical areas of the business.

The TANA design uses a twin drum, rigid frame and crushing teeth to compact materials with fewer passes. The rigid frame provides up to 100 per cent greater crushing force on a single drum when compacted to an oscillating four-wheeler of a similar weight.

The wide and level blade allows for an even level swing and traction is supported by no slipping or sinking wheels. The crushing teeth are made of solid steel and 200 millimetres in height, while providing up to 28 footprints per square metre and maximum kneading effect of waste.

Its TANA Control system improves driveability with a user-friendly interface with a simple operating menu and four-colour display. The monitoring system of the system helps the operator determine any faults and prevent damage from occurring.

The combination of fewer passes and better compaction allows operators to manage their waste in a more efficient way.
