TECHNOLOGY | RECYCLING AND RECOMPOUNDING
Right: Umac’s new ReadyMac 1109 TVE is a standardised machine based on Erema’s TVE technology, which is suitable for many standard applications and can be supplied at short notice
PP, PS, PC and PA 6 materials. Film, regrind and other types of material can be processed at rates up to 450 kg/hr depending on material. The Ready- Mac series is based on Erema’s Intarema TVE recycling technology, which is designed to manage difficult-to-recycle materials such as heavily printed films and/or very moist materials. The TVE line offers ultrafine filtration, thorough melt homogenisation and high- performance degassing in a single-step approach. “The TVE technology with degas- sing and the SW RTF filtration system with its backflushing mechanism ensure a very high pellet quality that meets the criteria of a very wide range of standard applications,” says Stölnberger. Umac says the prefabricated ReadyMac machine

is offered without options or variants, although the system is otherwise complete and ready to produce. The ReadyMac 1109 TVE is the initial model. The Powerfil business unit of Erema, responsible for development of high-performance melt filters for plastics applications, has introduced a rede- signed continuous filter featuring 50% more screen surface area compared to the previous model, which ensures lower pressure and temperature at the same throughput rate. The Erema 2/406 laserfilter is ideal for heavy contamination applications and can handle impurity levels up to 5% with filtration as fine as 70 micron while continuously cleaning the screen with a scraper, says Robert Obermayr, head of the Powerfil business unit. The Quattro version of the new LF 406 laserfilter can filter up to 9,000 kg/hr of melt. The larger screen surface area allows the throughput capacity of the recycling plant to be increased while maintaining the other parameters because a significantly higher rate of plastic melt can be filtered. Erema is launching its Intarema TVEplus line in a new double filtration machine configuration. The DuaFil Compact configuration produc- es double-filtered,
ultra-fine recycled pellets and is suited for particularly
challenging post-consumer materials such as supermarket packaging films. It is also launching several other technolo-
gies, including a new EcoGentle plasticising technology for its Vacunite and Vacurema PET recycling systems that significantly reduces energy consumption and features

gentle treatment of the melt. The company will also introduce a solution for turning PET fibre produc- tion waste into rPET fibres for higher-value end applications. The new solution combines a recycling technol-
ogy featuring ultrafine filtration with an additional intrinsic viscosity (IV) optimiser. The resulting rPET fibre can be used 100% in the production of ultrafine fibres up to 2 dtex, the company says. The develop- ment is the result of work at the company’s newly established Fibre Recycling Centre, where customers can also evaluate their own fibre materials. Erema has also developed a machine concept it calls PCU TwinScrew, which combines its patented material PreConditioning Unit with a twin-screw extruder. A demo unit will be installed at its new R&D test centre at its headquarters in Ansfelden, Austria. Erema is addressing chemical recycling with the development of a new machine series for mechani- cal material processing, a step that it says is often at the beginning of the process chain for chemical recycling to prepare input streams and ensure a reliable, continuous and energy-efficient flow of feed material. Its new Chemarema series features extrusion technology that can be adapted to the application requirements and is designed for downstream chemical processes. Erema also began construction this year on a new 1,550 m2
R&D centre at its Austrian headquar-
ters to develop plastics recycling technologies for waste materials for which there is currently no satisfactory circular economy solution. “While some plastics processing loops such as
PET bottles have already been closed, many other plastic waste streams still require a great deal of R&D in cooperation,” says Erema Managing Director Markus Huber-Lindinger. The centre will consist of two halls and a new
office building with 50 workplaces. To increase its plastics competence in these areas Erema will offer cross-developmental and cross-company test machines and a laboratory. Employees from
