Nanomil

How a "dry powder" nanoworkshop works?

Various milling workshops produce nano-objects in the form of micronic powders on the NANOMIL platform. If only a fraction of the powders handled is nanoscale, the operations require confinement. All equipment (glove box, sorbonne, mills) must have external extractions with HEPA H14 filters ensuring control of environmental emissions. Apart from the risk of dispersion, the risk of explosive atmospheres linked to the flammability of certain powders is to be considered. Strict maintenance and waste management procedures must be applied.

How to optimize waste management?

Four categories of contaminated waste:

  • liquids (solvents) used for the actual grinding or for maintenance are treated by a specific treatment system,
  • solids, excluding heavy metals (incinerable) stored in a plastic drum with inner polyethylene jacket,
  • glassware stored in a plastic drum with inner polyethylene jacket,
  • heavy-metal solids (non-incinerable) stored in a metal drum with inner polyethylene jacket.
