- Safety of bio-based nanomaterials
- Additive manufacturing of bio-based (nano)materials
Environmental health and exposure Cellulose nanomaterials (CNM) may encounter the environment during production, with the waste streams or as accidental release. Another potential release point is at the end of their life, due to disposal or recycling. Release can take place also during product use, especially from products’ potential for wash-off during or after product
