Reïnkarneer: a common language for recycled content

The transition to a circular economy relies on trustworthy, practical information about materials. This week marks the official kick-off for project Reïnkarneer: an collaboration subsidised by the EU (JTF) that aims to develop a common language for recycled content. The project starts with plastics, but explicitly looks to translate the approach to other material groups. 

Reïnkarneer: op weg naar een gemeenschappelijke taal voor recycled content

Why we can’t do without a common language for recycled content

Recycled materials play an increasingly important role in European industry, but their application lags behind the ambitions. Not because of a lack of motivation, but because of a structural problem: not enough clear information. 

Companies face a variety of challenges:

  • geopolitical tension that put pressure on resources;
  • dumping of cheap virgin plastics on the European market;
  • blending requirements coming from legislation;
  • and a growing demand for reliable, verifiable data about recycled content. 

Without a common understanding about characterisation and naming for recycled content, reuse remains complex, risky and often economically unviable to scale.

What is project Reïnkarneer?

Reïnkarneer aims to make the application of recycled content easier, more reliable and competitive. We do so by developing:

  • a standardised characterisation of recycled materials;
  • a uniform nomenclature – or coding – that gives direct insight into application areas;
  • digital product passports in which we record this information.

Deze digital product passports acts as a dynamic information carrier in which properties, origins and application areas of materials are recorded transparently.

From plastics to other material groups

Even though the initial focus will be recycled plastics, the ambition reaches further. Reïnkarneer aims to raise the volumes of recycled content in:

  • plastics;
  • metals;
  • minerals;
  • and biogenics.

By creating one recognisable system, the conditions arise to scale recycled content across industries. This makes it much easier for producers, recyclers and designers to apply recycled materials more often and in larger volumes.

Practical, data-driven and supported by AI

Reïnkarneer runs from 2025 to 2027. During these two years, we combine various approaches

  • extensive literature review;
  • in-depth material analysis;
  • application of AI and data analysis;
  • and above al: practical use cases.

The practical approach is crucial. By working with recognisable examples from frontrunners, other companies and knowledge institutes can not only understand what the new language is, but also how they can leverage it themselves to improve their own processes.

Collaboration as key to success

Reïnkarneer is a collaborative project in which industry, knowledge institutes and authorities strengthen each other. The official kick-off this week took place at Brightlands Chemelot, together with Stimulus, marking the official start of the project.

De upcoming period we will be sharing updates on:

  • important milestones;
  • workshops and interactive sessions;
  • webinars in which knowledge and experiences are shared.

That is how we build a broadly accepted system that contributes to the transition to a circular economy.

The development of a common language for recycled content is not a theoretical exercise, but a crucial step towards large-scale reuse. Through transparency, standardisation and collaboration, recycled content can fulfil its potential.
