Last week, the "Intarema 906TE" regranulation system from Erema Engineering Recycling Maschinen und Anlagen GmbH at the IKK - Institute for Plastics and Circulation Technology at Leibniz University in Hanover was put into operation. The IKK is thus starting practical cooperation with the manufacturer of plastic recycling plants and system components. Extensive research on the subject of closed loop technology can now begin.

As a permanent loan, the IKK has a fully equipped, compact recycling system based on single-screw extrusion technology at its disposal. It has extensive online analytics to determine, for example, the mass flow rate or the color of the material and, shortly, the chemical composition in the process.

"The future goal is to use this technology to develop sophisticated products from recyclates, taking into account quality requirements and quality management," says Prof. Endres, director of the institute. "Of course, the correlation between the composition of the input streams and the output quality depending on the parameters of the recycling process also play a role." In principle, the "Intarema" is able to process any thermoplastic material with a low bulk density. This includes contaminated and non-soiled thermoplastic (bio) plastics, mainly in the form of synthetic fibers and foils, but also granulates, powders, regrind and composite materials. In the central unit, the so-called preconditioning unit (PCU), the thermoplastic starting material is first prepared in the best possible way for the extruder, and then filtered in the extruder through the continuously working partial surface backwash filter with two carrier pistons.

“Of course we also want to take a close look at the system itself and see how the wear on the granulating knives and / or the perforated plate can be detected? Or perform flow simulation in the PCU, look at the wear layers of the screws used and measure the viscosity of the materials. In doing so, we build on corresponding research projects but also on the creativity and thirst for knowledge of our engineers of tomorrow by supporting and promoting student theses in this area together with Erema ”, concludes Endres.
