National Cleantech Conference seeks EOIs

The National Cleantech Conference and Exhibition (NCTCE) is seeking expressions of interest from event sponsors and exhibitors looking to showcase clean technology innovations.

In its second year, NCTCE will take place at the Brisbane Conference and Exhibition Centre on the 3-4 August.

Cleantech’s 2020 theme is fast tracking sustainable growth, with a program covering all sectors including water, energy, waste, mobility, agriculture, manufacturing and built environment.

According NCTCE Event Director Peta Moore, developing clean technologies is key to mitigating the impact of climate change, while creating new economic opportunities.

“I, like so many, am filled with horror as I watch the fires destroy so much of our country. While I am one of the lucky people not personally affected by the flames and smoke, it has still been an emotional time, a time of despair and frustration,” she said.

Ms Moore said after years working in the cleantech sector, she knows of multiple organisations, businesses, start-ups and innovators developing sustainable solutions around the country.

“As a team of conference organisers, my business, Nectar Creative Communications, is doing what we know how to do best. We are putting on NCTCE and are determined to make a positive impact on this issue by supporting the sector’s growth and commercial implementation,” she said.

The two-day program will focus on cleantech as an instigator of innovation, economic development, creative collaborations and inclusive prosperity.

Program Director Tiffany Bower said the national platform will bring all the major players from the cleantech sector together.

“NCTCE is not focussed on just one solution – it’s a multi-sector event – because it will take a holistic approach, across technologies, behaviours and policies,” she said.

“The conversations at the event will encompass energy, water, waste, built environment, transport, agriculture and manufacturing, because these days, projects aren’t just an ‘energy’ project or a ‘water’ project – they are often across all of these sectors.”

Ms Bower said a key topic of the 2020 event will be investment opportunities and access to funding.

“Many people don’t realise there are government agencies at all levels already doing great work in this area. There is funding available and resources they can access to help build their cleantech innovation and business,” she said.

“Our speaker program aims to spotlight the best-practice case studies, the innovative partnerships and new business models to help delegates navigate their way through the implementation process.”

NCTCE is working in partnership with industry groups such as Climate-KIC, EnergyLab, Cities Power Partnership, Brisbane’s CitySmart and the Australian Electric Vehicle Association.

“It’s really important to us that this conference is accessible to the small businesses and start-ups that comprise the majority of the cleantech industry,” Ms Moore said.

“We have kept ticket prices as low as possible, while ensuring a world-class education and professional development program.”

Tickets go on sale mid-February. For more information click here.

Immersed in industry: VWMA Waste Expo site tours

The Victorian Waste Management Association’s recent industry site tours took delegates through a range of resource recovery and manufacturing facilities.

The partnership between the Victorian Waste Management Association (VWMA) and Waste Expo Australia was particularly significant in 2019, given current challenges facing the Victorian arm of the sector.

While the event had a national focus, Mark Smith, VWMA Executive Officer, says Victoria was lucky to have Waste Expo located in Melbourne.

“We support Waste Expo because of the relevance this national event brings to the Victorian landscape, with thought provoking discussions and presentations on everything important and impactful to the sector,” he says.

As a strategic Waste Expo partner, VWMA ran three concurrent industry tours on the Friday following the expo, a first for the leading waste and resource recovery event.

Hosting a wide range of delegates including representatives from the Metropolitan Waste and Resource Recovery Group, industry heavy weights such as TOMRA, local government agents and small business owners, VWMA’s tours were designed to educate and stimulate conversation.

The day’s events included a construction and demolition tour, an organics tour and a packaging process tour.

“Working with industry partners Alex Fraser, the Australian Packaging and Covenant Organisation (APCO) and the Australian Organic Recycling Association (AORA), VWMA ran the tours to bring the steps industry is taking to support Victoria’s recycling agenda into focus,” Mark says.

As attendees gathered at the Melbourne Convention Centre on Friday morning, many expressed difficulty over choosing which tour to attend.

After an opening address from Mark, delegates piled into three separate buses, each with an industry specific tour guide.

The construction and demolition tour, sponsored by Alex Fraser, included site visits to Bingo Industries West Melbourne Facility, Alex Fraser’s Sustainable Supply Hub, a Level Crossing Removal Project site and the Toll Shipping’s terminal at Webb Dock.

Bingo Industries West Melbourne Facility is established on a site acquired 18 months ago by the company, with Bingo pouring $23 million into the facility since then. The site allows Bingo to convert waste into seven different products and has capacity for around 300,000 tonnes per annum. The company aims to achieve a 75 per cent recovery rate on-site.

At Webb Dock, Alex Fraser has worked with contractor Civilex to develop a heavy-duty pavement which incorporates reclaimed asphalt pavement (RAP) that meets VicRoads guidelines. The pavement base layers are comprised recycled glass sand and recycled concrete.

As part of the Level Crossing Removal Project, the Western Program Alliance used Alex Fraser’s recycled sand as bedding material for the combined services conduit housing the communications and power cables. The grade separation was undertaken at Kororoit Creek Road in Melbourne. The low embodied energy material replaces virgin sand with all 900 tonnes diverted from landfill at a lower cost.

Finally, Waste Management Review got to explore where Alex Fraser’s recycling happens, touring its Laverton North supply hub where more than one million tonnes of C&D waste, and one billion bottles of glass waste is reprocessed to make the quality construction materials needed to build greener roads.

A climb to the top of Alex Fraser’s high recycled technology asphalt plant topped off the excursion. The new $18 million faciliity is capable of producing over half a million tonnes of green asphalt per year, utilising the recycled glass sand and RAP produced in its collocated recycling facilities.

Shifting material focus, the Organics and Composting Tour’s first stop took attendees to the South Melbourne Market, where they were told about the market’s 32 tonne a year dehydrating compost initiative.

From there, VWMA and AORA directed the tour bus to Sacyr’s new indoor compositing facility. Michael Wood, Sacyr Environment Australia Consultant, guided the group through the 120,000 tonnes per annum facility, and explained the challenges associated with adapting a European model to an Australian environment.

The group was then guided through Cleanaway’s South East Organic Processing Facility and food depackaging unit.

Melinda Lizza, Cleanaway Development Manager, explained the depackaging unit’s 150,000 tonnes per annum capabilities, before handing the tour over to Michael Lawlor, Cleanaway Operations Supervisor.

After the tour, the group had lunch with the Cleanaway crew and discussed interactions with the EPA and growing levels of scrutiny on the compost industry.

From there, the group was driven to Bio Gro’s Dandenong South Facility, where Sage Hahn, Bio Gro General Manger, explained the company’s approach to organics diversion and composted mulch production.

After taking the group through the Bio Gro site, Sage fielded a range of technical questions and detailed the mineral additive process of mulch manufacturing.

Doug Wilson, AROA Victoria Admin Officer and compost group tour guide, says the day allowed delegates to closely inspect organics processing.

“At the very time when the state government is bringing the circular economy into focus, the organics tour took delegates on an interactive experience with some of Melbourne’s most exciting and innovative organics recovery technology,” he says.

The APCO packing tour, which was delivered in partnership with the Australian Food and Grocery Council and Australian Institute of Packaging, took attendees to Ego Pharmaceuticals, the South Melbourne Markets and recycled plastic manufacturer Replas’ Carrum Downs site.

Of the APCO tour, Mark says industry is at a critical time where collaboration is essential to address challenges in the packaging supply chain and achieve the 2025 National Packaging Targets.

“Great stuff happens all across Australia by the waste and recycling industry and many organisatsions that we partner with,” Mark says.

He added that these were areas of interest that were not spoken about enough.

“It was exciting to see demonstrations of the circular economy in action. Parts of our sector are leading on this front and there are scale interventions that only really need the appropriate government policy to delivery environmental, economic and social benefits to Australia.”

He says this was clearly demonstrated on the tours in the Victoria context.

“Industry is leading on parts of this and it’s important to acknowledge the good work being done locally.

“A big thanks to all our partners for coming on board and collaborating with us.”

Treading carefully on waste exports

It’s time we transformed into an economy that values all our resources and takes accountability onshore, writes Matt Genever, Director Resource Recovery, Sustainability Victoria.

The announcement by the Council of Australian Governments in August that Australia would ban the export of certain types of waste came as a surprise to most in the industry.

Global markets are already closing their doors to some degree, but Australia is still exporting around four million tonnes of material annually despite import restrictions set by China and other countries. Thus, the decision will certainly have implications for Australia’s domestic sector and the impacts will depend on how the ban is enacted and what materials are targeted.

Waste versus commodity

The intent of the ban is clear and easily justifiable. The images seen across media earlier in the year of mixed Australian waste, including soiled nappies, turning up at multiple Asian ports were not well received by the community. The social license of this great sector is already under siege and these images certainly didn’t help.

However, the situation is much more complex than this. It is unlikely that anyone could successfully argue that soiled nappies represent a tradeable commodity, but it does beg the question of where, and how, we draw the line between a waste and a commodity.

The recyclables being targeted as part of the ban include plastics, paper, glass and tyres.

Over the years, we’ve become more opportunistic in moving large volumes of plastics and paper offshore, which has led to less work being done locally to fully separate or “add value” to these resources.

In the case of tyres, there are valid questions being raised about where whole tyres, in particular, end up and how they are treated.

It’s this idea of “value adding” that offers the greatest opportunity for Australia, and equally where the most work needs to be done from the perspective of defining the boundaries of the ban.

How far does one need to go to add value? Is it simply separating material into different material types or is it fully commoditising it into a manufacturing-ready feedstock?

This is a conversation that Australia, and other nations, has been having for years.

In fact, there is a whole document dedicated to this called: Australian Waste Definitions: Defining waste related terms by jurisdictions in Australia. It is certainly not bedtime reading, but it is worth looking at the many and varied definitions we have for waste across each state and territory.

Words like “rejected”, “abandoned”, “surplus” and “discarded” commonly appear, as does the phrase “where not intended for recycling”.

In a world where one person’s trash is another person’s treasure, there is a fine line that must be walked here in developing these definitions.

Balance is everything

The complexity in defining a waste and how and when it becomes a commodity should not be the driving force that diverts us from this course of action. Like so many things in this system, it’s really all about balance.

We have an obligation to protect human health and as global citizens this needs to extend far beyond our own ocean-locked borders. Having said that, we also have an obligation to ensure that we are positioning our sector to develop its own domestic capacity and have the ability to participate in a thriving global commodity.

The sweet spot in here offers pause for some very optimistic reflection. There are already strong signs that industry is in a state of growth.

New investments are coming online and many businesses have already taken the leap toward commoditising the materials they collect. From hot-washed PET going into new bottles to government procurement of glass sand, the tide is most certainly turning.

So, Australia’s collective decision to ban exports needs to support and accelerate the change underway but at the same time consider our place in a global marketplace – one where we already have high operating costs (energy, in particular) and high
labour costs.

When one door closes, a window opens

Regardless of definitions, the idea of value-adding or commoditising our resources is one that is appealing. The opportunities for economic growth, new skills, new infrastructure and new jobs in the recycling sector are significant, but are only the tip of iceberg.

When we start commoditising our resources domestically, a whole range of opportunities for local manufacturing emerge. I was immensely pleased with the level of interest in Sustainability Victoria’s recent Buy Recycled Conference 2019.

I spoke with a number of manufacturing businesses that have the capacity right now to absorb more recycled content but are unable to source it from the local market. With the door to exports closing, its heartening to see the window into our domestic manufacturing is well and truly open.   

While there are probably more questions than answers in the commentary above (in the spirit of walking a fine line, I too must traverse my own path of balance), there is no doubt in my mind that the rewards here far outweigh the risks.

We’ve got to get the definitions right. We’ve got to get the balance right. But it’s high time we transformed into an economy that values all our resources, takes accountability for their management onshore and is focused on adding value and commoditising material when it reaches end of life.

MAC 111/2 baler

The MAC 111/2 baler is characterised by its long-lasting, robust and easy maintenance capabilities.

Following the success of the MAC 2 range, the MAC 111 is now available with updated features and extended channel sections for higher compaction.

Available through Australian distributor CEMAC technologies, the baler has been designed to treat large quantities of material in a short space of time, including paper, PET, metals and refuse-derived fuel.

Using 15-millimetre Hardox 450 steel, bolted as opposed to welded for easy changeover, total protection of the internal parts of the baler is achieved, increasing the lifetime of the machine.

Using REXROTH variable flow pumps and high efficient IE3 electrical drives, Macpresse also further improved the hydraulic block for better wear resistance and counter pressure control.

The trolley runs on eight high strength bearing side rollers with enlarged diameters. The ram features hinged front guards to stop wire blockages.

In terms of compacting ability, the compacting cylinder provides a thrust of 170 tonnes at 320 bar, completing a full forward/baling/return cycle in 12 seconds with material.

Additionally, a movable tying unit connected to a hydraulic cylinder can be used during the cutting and twisting phase of the wires, proving to be particularly useful for difficult-to-bale materials. The machine can be optionally equipped with a POLY-TIE wire tying system.

SSE Europa also offers a Siemens TP1200 operating panel and software for real-time diagnostics.

Palfinger finds its niche at AWRE

Palfinger’s new NSW Key Account Manager Seth Ozbas found the company’s DINO T22A unit was in high demand at the Australasian Waste and Recycling Expo.

When Palfinger began exploring which of its hookloader units to showcase at the Australasian Waste and Recycling Expo (AWRE), the team identified its DINO T22A hookloaders as the ideal fit.

The conference’s NSW-centric location meant that a hookloader with the capacity for various rail widths and hydraulically adjustable hook heights was highly sought after, inspiring the team to display the unit on the show floor.

Supplied with either a hydraulically adjustable arm or an articulating arm, the DINO T22A is ideal for various waste streams, from construction and demolition waste to organics.

Palfinger clients are handling a range of challenging waste streams and the company recognises that containers vary in design, with multiple rail widths and assorted hook heights creating logistical challenges.

Having a single hookloader that can collect most containers is a strong value proposition for Palfinger’s diverse range of customers in NSW.

Holding AWRE in October timed well with new NSW Key Account Manager Seth Ozbas having just come on board.

Joining Palfinger in August, Seth was keen to meet and greet Palfinger’s new and existing customers.

His main responsibilities are to ensure Palfinger maintains its strong connections with its existing NSW customer base, while also working to forge new relationships with waste operations and fleet managers.

With more than 10 years’ experience in mining and construction, Seth is an expert in hydraulic equipment.

Seth explains he first moved to Australia last year where he worked for Wam Australia – a company based in Italy manufacturing bulk handling equipment.

From there, he stumbled upon Palfinger after discovering their products online and was immediately impressed with their quality of build.

He says he is determined to ensure Palfinger’s strong reputation in the cranes sector is equally as well-known in waste management, an area Seth considers a personal passion.

“Waste management is an established industry, experiencing rapid growth as consumer sentiment shifts towards reducing our impact on the planet,” Seth says.

“NSW is an interesting state and I look forward to learning more about our various customers and applications.”

Seth says that the majority of Palfinger’s diverse range of NSW customers are in the Sydney CBD or western suburbs, with a number also spread across regional areas, an area he hopes to continue to grow.

While he is new to the waste industry, he says AWRE has helped him forge connections with new and prospective customers.

Seth says the DINO T22A has been an easy unit to sell in NSW, given the demand to carry a variety of containers.

“Waste managers are knowledgeable and they know what they want most of the time, so it’s about combining our technical capabilities to suit their needs,” Seth explains.

Glen Woodrow, Hookloader and Skip Loader Account Manager at Palfinger, says the DINO T22A hookloaders are unique to Australia.

“We manufacture products that are bespoke – it’s as simple as that. This hookloader is not sold anywhere else in the world because of our unique customers needs, particularly in NSW,” Glen says.

He says that historical designs have had limited clearance on the front of the bin due to a large hook, an issue the DINO eliminates.

Glen explains the DINO’s hydraulically adjustable hook will pick up any bin at any rail width or height from 1360 to 1650 millimetres. As an added benefit, the unit comprises front bin locks for seven points of contact ensuring NSW customers can secure their loads safely.

The colour scheme of black and yellow is a design that stands out on the AWRE floor, complementing Palfinger’s red backdrop and brand promise of lifetime excellence.

Glen explains that the units all originate from France and can be customised to suit customer’s colour needs.

Augmenting the unit is Palfinger’s PAD controls – an intelligent system that aims to provide users better information and improve safety. The controls include features such as automatic cycle for increased safety and additional information, including real-time record data and information displayed on the truck dash.

“Through our digitisation process, Palfinger is looking to make its units easier, smarter and faster. The new process removes all relays out of the control circuitry, so it’s quite a maintenance-free system,” Glen explains.

He says the PAD control box is an intelligent system and will inform users if the unit is not set up correctly.

“If you’re trying to tip and have the front bin locks in instead of out, it won’t go into tip mode,” Glen says.

“If the vehicle is not ready to travel and you have a bin unlocked, the audible warning will tell you it’s not safe to travel, even if you disconnect the PTO.”

He says that PAD controls are offered in both the T22A articulated DINO unit for low loading and T22T – a telescopic unit able to pick up every bin on the market.

Next generation AORA

AORA’s new Executive Officer Peter Olah speaks with Waste Management Review about the association’s plans to support and strengthen the Australian organics industry. 

The organics industry is in interesting times. While awareness over the importance of sustainable organics management has never been higher, compliance costs, regulatory changes and disrupted end markets are causing problems for small and medium enterprises.

How to effectively manage and process food waste is gaining traction though, with Infrastructure Victoria’s Recycling and Resource Recovery Infrastructure Evidence Base Report suggesting consistent approaches to FOGO are critical to achieving greater overall resource recovery rates.

Though this is likely welcome news to the Victorian arm of the organics sector, across the border in NSW, the situation is murkier.

In October, the NSW EPA reaffirmed its 2018 Mixed Waste Organics Output decision, stating the authority had no intention of amending its revocation of the material’s resource recovery exemption order.

For Peter Olah, the Australian Organics Recycling Association’s (AORA) new Executive Officer, the organics industry’s current challenges present an opportunity for growth.

“While I’m entering my new role at AORA in a challenging time for not just the organics industry, but the recycling industry at large, I’m excited to face those challenges head on and support the organics industry as it advances,” Peter says.

Peter, who currently serves as the Surveying and Spatial Sciences Institute’s Chief Executive Officer, has an extensive background in politics and public administration.

He previously worked on the private staff of a NSW Premier, and served as a Policy Advisor to Ministers for Justice and Police.

Furthermore, Peter served as a Hurstville City Council Councillor in Sydney for 12 years, including three terms as Hurstville Mayor and three as Deputy Mayor.

“I also worked with NSW State Transit for seven years, fulfilling a number of management functions for the organisation’s board and CEO, including projects in government and customer relations, public affairs, industrial advocacy, internal communications and cost efficiency,” he says.

Drawing on this leadership experience, Peter intends to help AORA deliver the objectives laid out in its 2019-2022 National Strategy.

“The strategy’s mission statement is to work with stakeholders to facilitate the conditions through which surplus organic material can be sustainably and cost-effectively recycled.” Peter says.

“Furthermore, we intent to promote the beneficial use of compost  and mulches in primary industries.”

In addition to the overall mission, Peter says AORA have three key objectives, including strengthening AORA as the peak body for the organics recycling industry and championing a pathway to optimise closed loop organics recycling.

Additionally, he says, AORA intends to establish and participate in knowledge hubs for recycled organics research, development, extension and communication.

“I will use my experience in stakeholder management and knowledge of political processes to ensure our member’s voices are heard and continue the advocacy and industry support role of AORA,” he says.

“As the central body for organics in Australia, I also intend to ensure the sustainable growth of the association.”

To achieve this, Peter says he will take time to speak with members about their concerns and ensure those concerns are further discussed with the AORA board.

One of AORA’s next steps, he says, is collaborating with members to establish standards and best practice certifications programs.

“AORA’s members are leaders in the organics space, and drawing on their expertise, I hope to use my position to identify, communicate and celebrate best practice strategies, technologies, performance and products,” he says.

“By working together, AORA can help create an environment where the work of individuals and organisations in the organics industry leads the way to a more sustainable Australian future.”

Packaging belt life to capitalise on industry growth

As the 2025 National Packaging Targets deadline approaches, resource recovery facility operators are presented with an opportunity to capitalise on expected throughput growth.

Between 2017-18, Australia generated 4.4 million tonnes of packaging waste, with only 68 per cent collected. Of that 68 per cent, 56 per cent was recovered via recycling.

In contrast, the national packaging targets aim to ensure 70 per cent of all plastic packaging is recycled by 2025. In addition to delivering significant environmental outcomes, the targets are set to grow economic opportunity in the sector through increased material availability.

To capture this potential, Mark O’Brien, BSC Product Manager, says recycling plant operators need to invest in streamlined equipment processes to ensure consistent throughput levels and quality recyclate. He adds that this includes the installation of durable and high efficiency belt drives.

While belt drives might not represent the most high-tech or glamourous component of an average recycling plant, Mark says superior strength and high grip belts are critical to maintain operations and minimise downtime.

“Sorters, conveyors and crushers are all central to the recycling process and are typically belt driven by an electric motor,” he says.

“BSC provides a wide range of belt drives to facilitate recycling applications, from our economy range right up to high performance V and Timing Belts.”

To provide a complete power transmission package, Mark says BSC works closely with American manufacturer of Carlisle drive belts by Timken.

Carlisle belts have been manufactured in the USA since 1905. The billionth Carlisle belt was sold in 2015. Recently acquired by The Timken Company, Carlisle belts are backed by a long history, yet continue to innovate and introduce new belt lines and products to market.

New lines include the Panther XT synchronous belt which acts as a powerful alternative to chain and polyurethane belts. Timken also launched its Drive Engineer mobile web app to assist in the design and maintenance of Carlisle belt drives in 2017.

“We have been working with Carlisle since the early 90s and have developed a very strong working relationship, which will continue to grow under The Timken Company for the marketplace,” Mark says.

BSC is the sole distributor of Carlisle belts in Australia and offers a range of Carlisle belts including Raw Edge Cog Belts. Super II, Blue Label, Power-Wedge, Wedge-Band belts, Super Vee-Band belts, Double Angle v-belts, Poly-Rib belts and Panther timing belts.

With over 15,000 different industrial belt combinations available, Mark says BSC are able to handle most power transmission applications; notably packaging recycling facility conveyor belts. He adds that different application requirements insist on varied and specific belt drives.

“In applications that require some level of slippage, a V belt is the best solution and you have variety of options within the Carlisle range” Mark explains.

“For applications with no slip requirements and synchronised drives however, I’d recommend a timing belt such as the Panther synchronous belt.”

According to Mark, correct installation and tensioning is necessary to ensure the proper operation of the entire belt drive and will guarantee long service life.

“When a drive is set up correctly and still failing, it likely points to something else incorrect in the system, belts act as a safety fuse in the system” he says.

“In that case, our engineering service can work on the machine to identify incorrect maintenance practices and drives or detect issues with other components that are affecting the belt life.”

Mark adds that by upgrading their belt drives, facility operators can reduce energy consumption, pulley sizes and hub loads through a lower quantity of belts required.

Additionally, he explains that belt drive construction and design can influence overall lifespan, power transmission and efficiency.

“The longevity of belt drives equates to less downtime, greater motor efficiency and reduced maintenance costs. Carlisle belt efficiency can be as high as 98 per cent,” he says.

“BSC recognises the positive impact its specialised products and services can, and do, have on helping customers become more sustainable across economic and environmental objectives.”

With the functionality of Carlisle belts specifically designed for the harsh environments of resource recovery, Mark says BSC is perfectly situated to assist capacity upgrades in the growing packaging recycling sector.

“BSC has extensive experience working with numerous companies in the packaging industry across Australia,” Mark says.

“That experience enables us to understand the special needs of those businesses and product processes, including energy conservation, high sustained speeds, continuous production, heavy leads and wet and dusty environments.”

Similarly, the company’s compactor bin range can also be manufactured to suit end user requirements, while delivering even greater refuse collection power thanks to the bins’ in-built compactor function.

Wastech’s auger bin range provides a versatile solution suitable for commingled recycling, screened grit, powders and similar waste products. With an in-built levelling screw, the waste is evenly distributed to the rear of the bin ensuring full use of space to maximise payload.

Its complementary range of bin lifters are capable of lifting and tipping bins from 80 litres through to 3000 litres. The capabilities allow Wastech to make it easier, safer and more efficient to dispose of waste and recyclables.

An array of processing capacity: Komptech and ELB Equipment

Reduced maintenance, time and expenses remain high priorities for leading international technology supplier Komptech, which is providing a point of market differentiation through its Nemus drum screen.

Contrary to competitor products, the Nemus leverages an open engine compartment accessible from all sides – adding an extra layer of safety for on-site material management. The engine unit is also hydraulically extendable allowing for streamlined oil checks.

With maintenance made easy, the side wall can be folded separately or together with the drum for further changes and cleaning.

The Nemus Maxx Primus drum screens by Komptech were designed for a variety of applications, including compost, wood/biomass, soil/gravel and shredded bulk, household, residual and refuse-derived fuels.

Controllable hopper and drum rotation speeds support precise material alignment. Drum overfilling is prevented by a load-dependent hopper control to support compost processing.

Komptech drum screens effectively process high-bulk materials such as wood/biomass through a feed hopper tailored to the drum size.

When it comes to processing excavated material such as sand, gravel and lightweight building rubble, Komptech has a solution for heavy materials. Solid contraries are kept back by a hinged hopper pre-screen and a hopper belt controller that prevents skewing on the belt.

In processing shredded, household, residual waste and RDF, the machine creates ample space between screen drums and side walls for a smooth operation.

Komptech also has a cellular application called “Connect!” which reports events and diagnosis codes, in addition to data on operating hours, fuel consumption and idle time by mobile radio to a central data sever.

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.
