State / form:
solid: particulate/powder
Reference substance:
Composition 1
Contributing activity / technique for the environment
Name of activity / technique:
ERC2 : For every transfer of the disodium fluosilicate there is an extraction slot nearby capturing the dust. The air of extraction circuit pass through filter before being rejected outside the facility.
Daily, the small amount of products fallen on the floor is collected in cans with cleaning machines. The cans are then destroyed by a dedicated company. So, there is almost no atmospheric or soil release.
