What are AMs?
• No formal definition
• A few in the literature
• Commonalities
– High value-added products
– Novel and unique functionalities
– Improved properties
– Superior compared to traditional
materails

Strength and weaknesses

Strength and weaknesses

Environmental estimation of the future Advanced Materials (AM) presence
Want:
• Current AM production and use
• Emerging AM production and use trends
• Environmental release of AM
Haves:
• Marked- value (gu)estimates for some AM
Seems to be pointing in two different directions
![Page 16: Kategorisierung von Neuartige Materialien · •Table 18: Categorisation of Advanced Materials based on DAMADEI (2013) •Table 19: Potential categorization and definitions of key](https://reader034.fdocuments.us/reader034/viewer/2022050607/5fae71ba8e889c106f4a045a/html5/thumbnails/16.jpg)
A few quotes from Expert interviews
• ”Providing supporting evidence for an emerging trends seems
in contradiction to one another”
• “Impossible to answer the question of whether there are key
gaps in the existing evidence with regard to fate of advanced
materials”
![Page 17: Kategorisierung von Neuartige Materialien · •Table 18: Categorisation of Advanced Materials based on DAMADEI (2013) •Table 19: Potential categorization and definitions of key](https://reader034.fdocuments.us/reader034/viewer/2022050607/5fae71ba8e889c106f4a045a/html5/thumbnails/17.jpg)
Regulatory review of AMs
Findings from the expert consultations
• ”No knowledge”’
• ”Do not know the terms and applications”
• ”No one knows how to do this for AMs”
![Page 18: Kategorisierung von Neuartige Materialien · •Table 18: Categorisation of Advanced Materials based on DAMADEI (2013) •Table 19: Potential categorization and definitions of key](https://reader034.fdocuments.us/reader034/viewer/2022050607/5fae71ba8e889c106f4a045a/html5/thumbnails/18.jpg)
Regulatory review
• For most categories of AM, we do not foresee any potential legal issues
![Page 19: Kategorisierung von Neuartige Materialien · •Table 18: Categorisation of Advanced Materials based on DAMADEI (2013) •Table 19: Potential categorization and definitions of key](https://reader034.fdocuments.us/reader034/viewer/2022050607/5fae71ba8e889c106f4a045a/html5/thumbnails/19.jpg)
Problem with definitions?
• Polymer according to REACH
“Substance consisting of molecules characterised by the
sequence of one or more types of monomer units”
• Polymer according to AM literature
“Polymers modified and reinforced with bio-fibers and/or
nanocharges that result in materials with very advanced
properties for innovative applications”
![Page 20: Kategorisierung von Neuartige Materialien · •Table 18: Categorisation of Advanced Materials based on DAMADEI (2013) •Table 19: Potential categorization and definitions of key](https://reader034.fdocuments.us/reader034/viewer/2022050607/5fae71ba8e889c106f4a045a/html5/thumbnails/20.jpg)
My ?s for U
Emerging Advanced Materials (AM)
• Do we need to AM definition?
• Preferred definition of AM?
• Preferred classification of AMs
• How to assess emerging trends?
• Any regulatory gaps that we have obviously missed?

risks associated with nanomaterials. It focuses
specifically on engineered nanoparticles, which for
example are used for coatings in the construction
and auto mobile industries, as well as on
developing policies and risk assessments to ensure
a safe and innovative development of
nanotechnology in Sweden and internationally.
