General information
- Short Summary
- An institute at a German university has developed a process for separating plastic composites and is thus making them accessible for recycling. For this purpose, an intermediate layer is injection molded or co-extruded between the plastic components so that only this layer can be melted. The related technology concept has been formulated (TRL2) and industrial partners are sought to refine the technology.
- Full Description
- Plastic composite recycling is greatly valued in today’s world. It is becoming increasingly important to recycle not only packaging, but also technical components. The current trend is to manufacture components from multi-material composites, but this is contrary to the single material requirement for recycling. Many components, such as vehicle dashboards, are manufactured by spraying a thin thermoplastic elastomer layer over a thermoplastic substrate. The combination of materials is selected to optimize bonding. It is then impossible to separate the layers out again for recycling. The only remaining recycling solution is often either thermal recovery (incineration) or non-pure recycling for use in applications with lower material requirements. Or such components can be disposed of or separated by means of solvents, but the latter solution is expensive and environmentally harmful.
To address these challenges a plastics technologyy institute at a German university developed a method for separating such composites. It uses an intermediate layer injected or co-extruded between the plastic components. This layer is selected to provide sufficient bonding in the operating temperature range, and a defined stimulation (thermal conduction or induction) can cause that only this layer melts. This allows plastics to be separated for single material recycling.
There are market opportunities as legislators are increasingly moving towards quotas for product material recycling. The automotive industry in particular is expecting measures to be introduced. However regardless of legal requirements, recyclability enhances product attractiveness to consumers. The method can be used with any application in which two types of plastic are firmly joined together. This includes multi-layer pipes, technical components, plastic panels, pressed parts, and much more.
The invention is technology readiness level TRL 2 The technology concept has been formulated. The university is offering interested companies the opportunity for joint technology refinement.
