Environmental Risk Assessment and Management Group (ERAM)

The ERAM group is pioneering methods and applications in environmental risk assessment of novel materials 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
  • Technology Assessment
  • Life Cycle Assessment



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


Application fields
