Polymer Recycling Innovation
Polymer Recycling Innovation
iPRACS is positioned to encompass all aspects regarding depolymerization of hard-to-recycle plastics via an integrated circular process. We are uniquely equipped to analyze and evaluate polymer structures, monomers and additives (molecules), process chemistry and modelling (smartly) and applying early-stage decision tools throughout the (circular) value chain (managed). Embedded within the University of Antwerp and closely connected to industry, iPRACS delivers both applied and fundamental research that accelerates innovation and enables more effective circular solutions.
From large to small Molecules (and back) trough chemical insights
A deep understanding of molecular systems and their physicochemical interactions is essential for optimizing chemical polymer recycling. iPRACS specializes in analyzing polymers, monomers and additives throughout the entire depolymerization process. Using state-of-the-art analytical techniques, we identify and characterize molecular structures, compositions and key material properties.
Our expertise includes:
- Chromatographic analysis
- Spectroscopic characterization
- Thermal analysis
- Diffraction techniques
These insights enable a better understanding of both feedstock materials and recycling products, providing the foundation for efficient and high-quality circular processes.

Interlinking multi scale polymer design Smartly
Developing next-generation polymeric materials requires the integration of chemistry, processing and performance requirements across multiple scales. Understanding how monomers—whether derived from established or emerging (renewable) platform molecules, or from polymeric waste—can react to form materials that meet specific performance requirements, is key.
iPRACS supports this process through:
- Reaction modelling
- Process optimization
- Machine learning and data analytics
- Integration of experimental and computational data
By combining insights from both polymerization and depolymerization processes, we help design materials with improved circularity and intrinsic recyclability, meeting the desired application properties.

Managing complexity
Every step in the polymer value chain adds complexity. Polymer formulations contain multiple monomers and additives, while end-of-life products often consist of different materials that require separation, sorting and recycling before they can re-enter the circular economy.
iPRACS applies entropy management principles to quantify and understand this complexity throughout the value chain.
Our approach enables:
- Assessment of material complexity
- Evaluation of recycling efficiency
- Estimation of energy requirements
- Analysis of environmental impact, including global warming potential
- Support for informed decision-making
By linking complexity, energy use, and sustainability metrics, we help identify the most effective circular pathways and guide the design of processes that maximize resource efficiency.
