matterr secures non‑refundable ERDF and Lower Saxony grant for ReNaTe

Key highlights
  • Non‑refundable funding approved by the European Regional Development Fund and the State of Lower Saxony for the ReNaTe project.
  • ReNaTe continues matterr’s collaboration with ICTV at TU Braunschweig; ICTV has been the central scientific partner since 2017.
  • The project will investigate valorisation of additional process streams from PET recycling to establish a marketable value component.
  • matterr’s core chemical recycling process recovers original monomers from PET waste; ReNaTe broadens focus to side streams to improve circularity and resource efficiency.

matterr ReNaTe PET side-stream valorisation project, Lower Saxony

Funding and partners

ReNaTe received funding approval from the European Regional Development Fund (ERDF) and the State of Lower Saxony. The project continues matterr’s collaboration with the Institute of Chemical and Thermal Process Engineering (ICTV) at TU Braunschweig, which has been the central scientific partner in developing matterr’s polyester recycling technology since 2017.

Project focus

ReNaTe will explore how additional process streams from PET recycling can be further valorised, aiming to establish a marketable value component and to improve the overall resource efficiency of the recycling process. The project will investigate potential uses for materials currently arising as additional process outputs.

Technical context

matterr’s core chemical recycling process recovers the original monomers from PET‑containing waste so they can re‑enter existing PET supply chains. ReNaTe expands that work by addressing side streams to move toward a more circular process.
