Environmental Risk Assessment and Management Group (ERAM)

The ERAM group is pioneering methods and applications in environmental risk assessment of advanced materials (including engineered nanomaterials), bio-based materials, plastics and chemicals and is developing approaches to implement the Safe and Sustainable by Design concept, enabling a comprehensive and early view of opportunities and risks of new materials and technologies.

Development and Application of Methods

  • Environmental risk assessment
  • Safe and Sustainable by Design (SSbD)
  • Experimental work on release of materials
  • Material and Substance Flow Analysis 
  • Risk/benefit assessment
  • Probabilistic Assessment and Meta-Analysis 
  • Guidelines and Tools to support informed decision making
  • Technology Assessment
  • Early-Stage Screening  and prospective LCA 



  • Advanced materials, inlcuding engineered nanomaterials and nanobiomaterials
  • Microplastics and nanoplastics, including tire wear particles
  • Plastics
  • Bio-based materials and polymers
  • Woody biomass
  • Protein-based polymers
  • Side-chain fluorinated polymers, fluoropolymers and perfluoropolyethers
  • Smart materials/products


Application fields

  • Textiles
  • Medicine
  • Electronics
  • Consumer products
  • Biosensors
  • Construction
  • Carbon capture and usage
