MeWa Recycling (above)

Glass-fibre-reinforced plastics (GRPs) are found everywhere - in vehicle bumpers and bodies, in aeroplane tails, in wind turbines, canoes, and waste water pipes and potable water tanks. The material is corrosion-resistant, durable and very stable. However, for these same reasons, it also poses a greater challenge to recycle. This is where a QZ 1600 Querstromzerspaner from the German company MeWa Recycling Maschinen und Anla-genbau comes in.

Fibreglass is resistant to chemicals, is highly resistant to corrosion and extremely robust. With GRP pipes it is now possible to transport water to and from households, irrigate dry areas, drain water from roads, tunnels and bridges, and use them to hold potable water. One trailblazer in this area is Hobas, which has its headquarters in Carinthia, Austria. In 1957, it developed the spinning manufacturing method to produce pipes made of glass-fibre-reinforced plastics for the first time. During this production process, the individual material components (glass fibres, polyester resin and filler materials) are injected into a rotating cylinder. The centrifugal forces compact the materials so they are ideal for building up the pipe from the outside in. This creates a cavity-free, gas-tight pipe wall. The inner layer is finished with resin. It is shaped so that it is completely smooth, giving it the best flow conditions for liquids. At the end of the production process, the end pieces of the pipes are cut off, ground and fitted with a coupling.

The only waste materials from this process are the off cuts and end pieces but these are not easy to recycle. In the past the pieces were shredded and fed into the cement industry as fuel. “Since then, technology has progressed so far that we can produce pipes with walls up to 100 millimetres thick,” explains Karl Marktl, who works in technical maintenance at Hobas”. The shredder technology couldn’t cope with walls this thick.

Hobas brought together a selection of GRP waste and sent the “most difficult pieces” to the German MeWa Recycling Maschinen und Anlagenbau test centre for testing. This is where, instead of a cutting system, the engineers used the patented QZ 1600 Querstromzerspaner to crush the waste. After a few tests, adjustments were made to find the right parameters, and the machine was soon producing the required fine material and was installed at the Carinthia HQ. This has allowed Hobas to quadruple the throughput of the high-speed shredders and reduce wear costs.

Herbold Meckesheim

Herbold Meckesheim plastcompactor

German firm Herbold Meckesheim produces machines and systems for the recycling of soft and semi-rigid materials. At IFAT the company will be showcasing its plastcompactor recycling system. Herbold says the equipment is particularly useful for waste requiring special conserving treatment such as foils, filaments and fibres of PET and PA.

Herbold says due to the low purchasing cost of the plastcompactor, its automatic operation and the low operating costs, the system has become an attractive alternative to a re-granulating extruder.

Herbold also offers a PET washing process, which it says, results in high levels of cleanliness with lower energy consumption. The company also has extended its range of products with a series of low-speed granulators available as two types – HGM 60/100 and HGM 60/145.

The HGM granulator is a single rotor size reduction machine that combines the benefits of a cutting mill with that of a shredder. It is used for the size reduction of difficult, particularly tough materials or those containing a lot of foreign bodies and can be used for both wet and dry process. It can be used with pre-crushed used tyres, bottles from domestic waste, metal-reinforced rubber or plastic parts, shredded waste from car recycling. The granulator has a thick-walled grinding compartment lined inside with exchangeable wear plates.

Herbold representatives will also be able to talk about the company’s range of components for pre-existing washing plants: wet-grinding granulators, friction washers, hydrocyclones, mechanical and thermal dryers and more.

Eriez Magnetics Europe

Eriez shredder

Eriez Magnetics Europe has doubled its stand size so it can showcase its Shred1 Separator launched last summer that uses ballistics to separate iron-rich ferrous from mixed metals and waste material in the post magnetic drum flow in scrap processing lines.

This separator delivers three distinct fractions with the first being a high value, low-copper content ferrous product. This valuable shred represents more than 70% of the flow and contains less than 0.2%of copper. 

The second fraction represents less than 20% of the flow and contains mostly mixed metals, copper and aluminium with steel housings or cores. Hand sorting of this fraction can be accomplished with relatively few pickers. The final low volume fraction representing less than 7% of the flow consists of heavy steel objects and light material such as fluff, rubber and some wire. This fraction can also be easily picked or sorted. 

With worldwide demand for steel on the rise, scrap processors that are able to supply steel mills with a high grade ferrous product are positioned well for the future.  However, with decline in availability of pure, high quality industrial scrap, processors are shredding more consumer waste than ever before.  Post consumer waste items like vehicles and appliances contain lots of motors, condensers and wire harnesses as well as cast aluminium pieces, all of which have steel housing, shafts of cores. This presents a big problem for most yards using current processing technology.  The Shred1 changes this dynamic and allows processors to differentiate themselves with a premium ferrous shred and demand a higher value per unit weight.

“The Shred1 is a welcome addition to the Eriez Recycling product portfolio and complements a lot of our already successful recycling equipment, says sales manager – recycling Carlton Hicks.


Pühler-HSM PET crusher

Baling press manufacturer HSM is sharing its stand this year with Pühler-HSM – launched at the end of last year – that manufactures stainless steel recycling presses. Pühler will demonstrate a drainage press will be presented which compresses full, disposable packaging such as Tetrapack, yogurt pots, PET bottles, and separates the packaging from the contents. Pühler’s range includes label presses and ice unpackaging machines.

HSM plans to unveil a number of products at the show such as the HSM PET CP 4988 crusher press combination for PET recycling. The system reduces the volume of empty PET bottles by up to 90% in one cycle and produces compact raw material bales. A dosing shaft ensures that the bottles are drawn in securely and achieves a throughput capacity of up to 4000 1 litre bottles every hour. Loading can be done manually or automatically. The drainage system discharges all the residual fluid before pressing. In the downstream baling press, featuring a pressing power of 11 tonnes, the crushed bottles are compressed into raw material bales and strapped three times, with a weight of up to 100kg. A scraper system reliably removes the compressed bottles from the crusher rollers which are made of specially hardened and ground steel.

The vertical baling press HSM V-Press 504 boasts a robust design with low space requirements and easy installation. It is an entry level modal for the disposal of packaging waste such as cardboard and foil.  With a pressing force of 40kN, up to six bales an hour can be compressed with a maximum weight of 50kg, depending on the material. The press has a HSM TSC (Torsion Control System) that monitors the angle of the press ram to prevent one-sided loads.


Pallmann Group will be showcasing its all-rounder “Tiger” PSRT 1000 x 1250 robust single-shaft shredder. Pallman says it is ideal for separating tyre rubber from steel inlays, cleaning tyre wire, shredding safety flooring, carpets, electric cables, electronic waste, and rubber seals with steel inlays. The company adds that its versatility means it can be retrofitted to existing systems or used as a stand-alone machine. It has a patented construction design so the rotation direction can be changed at regular intervals. This helps keeps the knives sharp and contribute to consistent product quality as well as reduce the maintenance required.

Also on display will be the Leopard PSRE Rotor, which can also operate in both rotation directions. Large screens, which open wide in the downward direction, together with large doors, make it easy to access the rotor and grinding chamber. The narrowing grinding gap makes it possible to dispense with a pusher and the rotor pulls the material into the cutting chamber.
