Make plastic green – Highly ef fi cient extrusion technology for recycling tasks Extrusion lines from KraussMaffei are particularly ef fi - cient for recycling tasks. They score with excellent melt homogeneity, a reduction of obtrusive odors and the tar- geted upcycling. EdelweissCompounding systems are an economic solu- tion for recycling and compounding segregated post- consumer plastics. The ZE BluePower are distinguished by their increased volume and a high speci fi c torque, which allows them to pick up and process the large-volume waste fl awlessly. The result is maximum throughput with high quality. ZE BluePower twin-screw extruders also provide the op- tion for sustainable solvent-based plastics recycling. The objective of this is solvent-free recycled material that can be enhanced like virgin material. Through openings in the housing and a vacuum applied to them, the extrud- ers safely extract the solvents from the melt. Depending on the requirements for the polymer being created, the process involves varying degrees of re fi nement. For in- stance, if you want to reduce the residual solvent content in the material from the original 30 down to 2 percent, a twin-screw extruder is suf fi cient. If degrees of purity in the ppm range must be reached, a twin-stage cascade is recommended.
