FAQs

 

The preconditioning unit can vaporise moisture contents of up to 8 % prior to feeding the extruder. This is the exclusive result of heat due to friction when the feed material is mixed, cut, shredded and compacted in the preconditioning unit. Special versions of EREMA plastics recycling machines can even process feed materials with a residual moisture content of up to 15% in a single step to produce completely degassed pellets.

EREMA machines in the series TVEplus® and VACUREMA® (for PET) are especially suitable for these materials.

We would be pleased for you to run a test with your own material to check out the performance of EREMA plastics recycling systems.

Thanks to its patented system featuring the melt filter before the degassing openings, the TVEplus® machine is particularly suitable for processing heavily printed and contaminated materials.

There are suitable melt filtration systems available too:

  • The EREMA partial surface backflush screen changer in the RTF series for medium to heavily contaminated material
  • The EREMA laser filter for heavily to very heavily contaminated feed material

Extruder barrel and screw are also available in an extremely wear-resistant hard metal design.

Double filtration in one extrusion step is also possible: coarse filtration/fine filtration with the TVEplus® system.

The preconditioning unit heats and softens the material very uniformly and carefully. This means that friction and thermal stress in the intake area of the extruder is very low. This "hot feed" method enables very short extruders to be implemented where the polymer spends only a short time in the extruder. As a result, MFI decomposition is reduced to a minimum.

Even lower MFI decomposition values are achieved using the INTAREMA® K edge trim recycling system. In this recycling system the material is melted (but not fully) in an extremely short extruder (L/D:7) and transformed into free-flowing pellets. Minimum energy requirements (0.12 to 0.18 kW/kg) and scarcely measurable MFI degradation are ensured.

During PET recycling, lowest possible IV decomposition, or even an increase in IV level of the material, is extremely important. That is why VACUREMA® PET recycling systems use vacuum reactors and are extremely effective and cost efficient for the crystallisation, decontamination and pre-drying of the feed material. An increase in the intrinsic viscosity (IV) of up to 8% is achieved by high vacuum and high temperatures.

Generally there is no need for elaborate and costly external pre-drying and external crystallisation of the processed material, or the use of chemical additives and/or solid state condensation used on other, conventional systems.

Spinning oil residues can present a problem, especially when recycling fibre waste. If the spinning oil level of the recyclate is too high then it cannot be used for fibre production because it will cause gas to form in the extruder and spinning will become impossible.

Spinning oils are largely eliminated in the preconditioning unit. High vacuum and appropriately high temperatures bring about a sharp increase in the vaporising intensity of most spinning oils. These are extracted from the cutter compactor in a gaseous state so that they do not enter the recyclate.

EREMA filter systems remove mechanical contamination extremely efficiently and have a long service life.

Thanks to the fully-automatic self cleaning system, a long service life is ensured even for very fine screens before the screen package has to be replaced.

Moreover, the laser filter produces the purest recyclate, even with heavily contaminated materials.

It is normally very difficult - impossible even - to process metallised film waste. The pellets produced on conventional plants are either overgassed or inadequately degassed.

With the TVEplus® system EREMA offers the right solution. This produces completely degassed recyclate - even from metallised film waste - for trouble-free further processing to high-quality end products.

Using the typical EREMA combination of preconditioning unit and extruder, even light, foamed materials can be perfectly recycled with a high output. There are no problems with oxidation or other disadvantages such as partially full extruders. The waste material can be processed without previous shredding, it just needs to be fed in as portions. In the cutter/compactor the material is cut and the heat generated by friction is used for precompaction.

That is how foamed polystyrene waste (EPS), for example, can be reliably pre-compacted by a factor of ten to twenty times that of its original density, heated and softened in the process and, as such, fed directly into the extruder. The result is stable, high extruder throughput, regardless of the bulk weight of the feedstock. This EREMA system is equally suitable for the processing of all types of foamed, thermoplastic materials, such as EPS, EPE, EPE, foamed PET etc.

When recycling plastic wastes with organic contaminants such as paper, wood, etc. there is a risk of gas forming in the extruder as they decompose. Foamed, non-usable pellets are the result, even if degassing extruders are used.

The problem with conventional degassing extruders is that the impurities still tend to form gases beyond the degassing zone of the extruder. This applies particularly in the area of the melt filter at the end of the extruder, where the impurities are filtered out and spend a lot of time on the filter screen. In practice, such contaminated materials are often extruded twice as a result. In the first extrusion step the gas-inducing impurities are filtered out, the second extrusion step degasses the clean material. The procedure as a whole entails high costs as a result.

These problems can be avoided by using the patented TVEplus® system. The melt filter is located in front of the degassing openings. That is why the problematic contaminants are filtered out mechanically first before the melt is double degassed. With TVEplus® you get completely bubble-free, melt-filtered recyclate in a single extrusion pass, even using materials with organic contaminants.

As standard equipment, EREMA extruders are supplied with highly wear-resistant bi-metal screws and barrels from 3S - an EREMA subsidiary. The properties relating to hardness, coating thickness and wear layer are guaranteed. The use of first-class, highly wear-resistant materials, has been standard at EREMA for many years, ensuring maximum plant service life.

In special cases (e.g. processing materials filled with fibre glass), extremely wear-resistant hardened armour screws and barrels are used. www.3s-gmbh.at

When pelletising abrasive, highly filled materials (polymer melts), tungsten carbide reinforced die faces are used.

"Every supplier tells me a different story ..."
It's not exactly easy to have an overview of the wide range of systems on offer for plastic recycling, let alone judge them.

EREMA recommends you do the following:
Visit potential suppliers of plastics recycling systems and try them out for yourself during a test run or demo.

Ask for references and talk to reference customers, visit them and then you can form your opinion.

We would be pleased to configure one of our test plants (free of charge) in our large Technical Centre especially for your plastic waste. We look forward to you visiting our company so we can demonstrate our technologies and their performance.

Let us organise or provide the information for your visit to one or several of our reference customers near to you. --> sales@erema.at

Thanks to our special process control, EREMA plastics recycling technology is ideal for manufacturing high-quality recyclate from sensitive materials.

EREMA technology is ideal for transforming the above materials or similar, sensitive materials, into pellets using a low-impact process.

Post Consumer plastics recycling normally requires a washing phase before pelletising. The preconditioning unit in EREMA machinery delivers excellent pre-drying properties. Feeding the system with washed plastic fractions with residual moisture contents of up to approx. 10 % is possible.

As a result, the drying process at the end of the washing system can be designed in a much simpler and more compact way.

The high-performance EREMA laser filter designed especially for post consumer applications combines ideally with EREMA cutter compactor technology to produce first-class pellet quality. In many cases, using EREMA laser filters means that smaller washing systems are required.
