WHY?

Polymers are essential in modern life, forming the basis of countless products. However, most are synthetic—polyesters (e.g., PET), polyamides (e.g., nylon), and polyurethanes (PU)—and pose environmental challenges due to slow biodegradability, fossil resource dependence, and recycling difficulties. Incineration, the dominant disposal method, also drives CO₂ emissions.

Bio-based polymers offer a sustainable alternative but currently makeup only 2% of the global market. A circular polymer economy requires shifting from fossil-based materials to renewable feedstocks and implementing efficient recycling and degradation strategies.

Biocatalysis is a key green technology in polymer science.
Enzymatic functionalization enables controlled polymer degradation via:

  • Monomer functionalization before polymerization.
  • Post-polymerization modifications of polymer chains.

Challenges include enzyme cost, stability, solvent compatibility, and activity on non-natural substrates. Optimizing enzyme-polymer interactions requires innovative approaches in enzyme engineering, bio-based substrate selection, and reaction condition optimization.

Computational tools have transformed enzyme engineering for small molecules but remain inadequate for enzyme-polymer interactions. Directed evolution, while effective for natural substrates, cannot fully capture complex polymer interactions. The lack of experimental data further complicates modeling.

COMENZE integrates computational and experimental approaches to develop a robust enzyme design pipeline. High-throughput virtual screening software will accelerate enzyme optimization for polymer applications. Combine computational and experimental methods for designing sustainable polymers by functionalizing monomers before polymerization and/or post-polymerization modifications

At the core of COMENZE is the training of ten Doctoral Candidates (DCs), equipping them with the skills to drive future breakthroughs in sustainable materials science. By fostering collaboration between academia and industry, COMENZE supports the goals of the European Green Deal and the Circular Economy Action Plan.

Research & Innovation

COMENZE explores new ways to design, modify, and recycle bio-based polymers using enzyme engineering. The project integrates computational enzyme discovery with experimental validation, enabling tailored enzyme design for enhancing polymer chemical recyclability and biodegradation.

The research is structured into three interconnected work packages (WPs):

  • WP1: Developing and optimizing new computational strategies to identify new enzymes for monomer functionalization and enzyme-polymer interactions.

  • WP2: Discovering and engineering enzymes to functionalize lignin-derived aromatics for biodegradable polymer synthesis.

  • WP3: Designing, screening and characterizing enzymes to anchor novel peptides to polymeric materials (e.g., polyamide).

These work packages support ten Individual Research Projects (IRPs), each addressing specific challenges in enzyme-driven polymer transformation.

David Pina - Commenze project manager

David Pina holds a PhD in Structural Stability of Proteins (2004). He conducted postdoctoral research at the Curie Institute in Paris and the University of Cambridge, UK.
In 2007, he joined the Directorate-General for Research and Innovation of the EC, and in 2009, he moved to REA, where he has taken on increasingly senior roles across various Framework Programmes. Most recently, he served as Head of Sector for Administration and Finance. Currently on sabbatical leave, David will be working part-time as the COMENZE Project Manager.

The Project Support Management Team will be supported by Marco Fraaije (RUG) as Training Manager, Silvia Osuna (UdG) as Communication Manager, and Nikola Loncar (GECCO) as Innovation Manager (IM).

The project Supervisory Board (SB) comprises one representative per beneficiary and associated partner and will also include representatives from the recruited Doctoral Candidates (DCs). The SB will coordinate the supervised training activities.

An external Scientific Advisory Board (SAB) will be involved in commenting critically on the research and training activities of COMENZE and suggesting new directions where appropriate.
