Practical Workshop: Use of Recyclates in Industrial Production - Opportunities and Risks / Introduction and Practical Experiences

Mon, 06/14/2021, 2:00-5:30 p.m.

InnoZent OWL e.V., Zukunftsmeile 2, 33102 Paderborn, Room ZM2.A.00.07 (first floor)

Recycled materials, especially post consumer recycled (PCR) materials, are excellent in terms of mechanical properties, but inferior to virgin materials in terms of the decorative quality of the surface. Here, many customers are not willing to compromise on quality. Even if post-industrial goods have clear advantages over PCR in terms of cleanliness and grade purity, there are also limitations here if, for example, rejects show significant material degradation or coating.

Our workshop addresses the following blocks of topics:

  1. Introduction: political background and legal requirements for the use of recyclates.
  2. Overview: Techniques for processing pure recyclate, blends of recyclate and virgin material, and recyclate and virgin material as a composite, e.g., by coextrusion or two-component injection molding
  3. Insight: Quality, quantity, delivery capability - What is possible?- Challenges of a recyclate producer.
  4. Exchange of experience: Along the value chain - Markets and customers

The aim is to find technical possibilities and arguments to increase the acceptance especially of post consumer recyclate.
