Liebherr 550 wheeled loader

From excavators to wheeled loaders, shredders and balers, manufacturers such as JCB, Liebherr-GB, CASE, Doosan Bobcat, UNTHA and Riverside Waste Machinery are meeting the ever-changing needs of waste material handlers. RWW catches up with them and their clients

With the current uncertainty in the waste handling sector, Chris Cox, JCB’s general manager for the waste and recycling sector, takes a pragmatic view of the future of resource management.

“Although oil values have now recovered somewhat, the recent price plunge had a knock-on effect on the industry, and plastic recycling in particular. Ongoing insecurity about oil production levels and prices will undoubtedly affect investment in the industry in the short to medium term.”

However, it is not all doom and gloom, according to Cox: “Worldwide there is a growing acceptance of the importance of better management of resources. We are confident that the sector will ride the current economic and political storms to play an increasingly important part in the world economy.”

The proof is in the pudding when it comes to customers’ choice of kit.

Economic Skips, a London-based professional waste management solutions company, chose JCB’s JS220 Wastemaster – a 22-tonne tracked excavator – to take on the large volume of waste the company handles every day.

According to JCB, the machine’s stable base means it can work on top of the waste rather than having to operate at ground level. This position, along with the JS220’s hydraulically raised cab, means the operator can easily see into the hopper being loaded, making the process safer and more efficient.

The intelligent reversible fan and wide-core radiator are also said to ensure the machine keeps cool even when it is working hard in the dusty environment.

The JS220 operates without a diesel particulate filter (DPF), which is claimed to reduce the danger of overheating and sparks, which is crucial when working with waste materials in such an enclosed space.

Meeting industry needs

As everyone in the waste sector knows, there is huge diversity within the material handling industry.

Mike Hanlon, material handling product specialist at Liebherr-GB, tells RWW: “The change in the Landfill Directive from the EU has forced companies to find alternative methods of dealing with waste. This has opened up various treatment options – for example, transfer stations, processing to end user products such as RDF, composting and even anaerobic digestion.”

Once a piece of kit has proved its reliability, some clients are happy to stick with the brand.

Willshee’s of Burton on Trent, an independent waste management company, has taken delivery of its fifth Liebherr machine to further increase capacity at its material handling facility (MRF).

A family-owned and operated company with more than 30 years’ experience of waste management, recycling and skip hire, Willshee’s is reported to have the capacity to recycle almost all waste, including wood, cardboard, paper, metal, glass, plastic, plasterboard and aggregates.

Ensuring reliability and efficiency

Managing director Dean Willshee stresses the importance of buying the right kit: “With 65 personnel and an annual turnover of £10 million it’s a growing business, and with the company handling over 150,000 tonnes of incoming domestic and commercial waste, it’s essential that our machines are efficient and reliable.”

The first Liebherr machine the company invested in was a Liebherr 550 wheeled loader and, over the past six years, the fleet has grown to five machines, with the latest acquisitions being a Liebherr LH22 material handler and a second 550 wheeled loader that has replaced the original machine.

This was followed by a second purchase of an R924 and then, in January 2014, an R904 material handler. An LH26 followed in January 2015 that is currently employed on wood sorting.

The MD says: “There has been very little downtime, and when we have had a breakdown the response has been swift and efficient.”

Scott Freeman, CASE business director UK and Eire, concurs with JCB’s Cox that the future of resource management looks bright. “Over the past few years, as other sectors have found themselves in troubled times, waste and recycling has continued to grow as the demand and pressure have increased on all sectors to recycle more.”

The GDC Group, part of global heating products manufacturer Glendimplex, purchased a CASE 521F XT waste configuration wheeled loader for its brickworks manufacturing plant in Brierley Hill, West Midlands.

The main task of the 521F XT, which is working in the recycling process at the Brierley Hill factory, is to load the bricks into the crushers and move the iron ore from the storage area into the plant.

Part of CASE’s F Series range, the 521F XT wheeled loader is said to be ideally suited for material handling duties in this type of challenging environment.

Using a 4.5-litre Stage IIIb engine, it is said to deliver maximum power for different work modes. It also benefits from selective catalytic reduction. According to CASE, this allows the engine to run at peak performance, which provides faster throttle response while also maintaining lower temperatures and delivering up to 20% better fuel efficiency over other solutions.

Although GDC Group had previously leased machines for this task at Brierley Hill, when its current lease was up it decided to purchase the 521F XT.

Moving materials

With the emphasis on high performance and fuel efficiency, Doosan Bobcat EMEA puts the spotlight on its DL200-5 and DL250TC-5 wheeled loaders. With bucket capacities of 2 and 2.5 m3 respectively, the DL200-5 and DL250TC-5 are designed to meet a wide range of material handling and loading applications.

According to Doosan, the DL200-5 and DL250TC-5 are powered by new engines meeting Stage IV emission regulations without the need of a diesel particulate filter and incorporate an electronic high-pressure common-rail fuel delivery system along with a turbocharger with a wastegate valve to improve power and fuel efficiency.

The after-treatment technologies being used in the engines are cooled exhaust gas recirculation combined with a diesel oxidation catalyst to reduce particulate matter, and selective catalytic reduction with diesel exhaust fluid injection to minimise nitrogen oxides.

The compactness and robustness of the DL200-5 and DL250TC-5 models are said to provide excellent manoeuvrability in narrow and confined spaces.

Giving waste a second life

Avanti Environmental Group is one of the latest resource specialists to open an alternative fuel production plant in the UK.

It opted for shredding specialist UNTHA’s bespoke in-feed conveyor which – once loaded by either a grab or wheeled loader – transports pre-shredded, high-calorific material into the XR3000C waste shredder.

The shredder’s indexable cutters and interchangeable screens are claimed to achieve a precise yet flexible shred, with a particle size as small as 30mm, in a single pass. The machine is also fitted with intuitive, ultra-responsive fire suppression technology, and a touchscreen control panel facilitates remote diagnostics from UNTHA’s Austrian HQ.

The shredded material then continues up a discharge conveyor fitted with over-band magnets to extract both ferrous and non-ferrous recyclates.

An eddy current separator – which draws out any aluminium – completes the UNTHA package. The homogenous confetti-like material is then baled and wrapped for onward shipment to end-users.

Avanti’s group recycling director Steve Kinley says: “UNTHA challenged us to think carefully about the input material, output speeds and the final product we wished to achieve, and I believe this has ensured we build a more efficient, intelligent and profitable plant.”

Waste baling technology

In the agricultural sector, the term ‘baler’ usually conjures up images of farming machinery used to compress crops, but for Allpress Farms an investment in waste baling technology has also proved fruitful.

The family-run firm grows leeks, onions, sugar beet, wheat and maize on more than 2,000 acres of land.

Advice from a fellow vegetable supplier brought Allpress to Riverside Waste Machinery, and a subsequent waste audit highlighted the role that a RWM 250 vertical waste baler could play.

With a large feed aperture, automatic bale ejection and retaining claws to prevent material from springing back, this medium-sized baler soon began to handle Allpress’s varied wastes with ease.

The improvements to Allpress’s waste storage, handling and disposal costs have led to the investment in a second RWM250 for Greenshoots, a producer organisation of which Allpress is a member. With twice the capabilities, the team can now handle two waste streams at once.

Currently baling approximately 3.5 tonnes of polypropylene film from flow-wrapped vegetables, 2.5 tonnes of polythene stretch wrap, and 4.5 tonnes of paper and cardboard per year, Allpress said it has saved £2,000 per annum on landfill and skip charges.
