In-house recycling at KraussMaffei

Transport crates made of plastic waste
The days when KraussMaffei stored and transported screw elements in wooden crates are a thing of the past. Instead, crates made from recycled plastic are now used.
The plastic crates are not only lighter and less expensive, but a good deal more durable. If, contrary to expectations, a crate does break, it is 100% recyclable. Currently, recycled materials from the market are being used.
As soon as next year, these are to be replaced by waste generated in-house. In addition to waste from production or test experiments, this also includes used or damaged crates that are taken back. KraussMaffei provides a genuinely closed loop of recycling.
The idea came from our in-house production in Hanover. After all, KraussMaffei unites extrusion and injection molding, which offers the ideal condition for this project.Franz-Xaver Keilbach

Thus, KraussMaffei is capable of processing and regrinding its own waste so that it can then be further processed on injection molding machines. The challenge in the injection molding application lies in injecting the material into the mold provided for this purpose. APCplus helps with this: the shot weight tolerance is held at the correct level the entire time, even though the recycled material has high viscosity fluctuations.
In the extrusion process itself, the materials are purified to remove odorous substances and mechanically reinforced to completely correspond to the properties of a crate. The two-stage purity compoundingLine from the Technical Center in Hanover is ideal for this purpose.
This project is a real win for KraussMaffei in many respects. First and foremost, the economical and ecological added value with which we take another step towards sustainability.Alexandra Coffey
