Most of the materials from which Hilti products are manufactured can be recycled. The materials must be

Drilling and sawing slurry
Disposing of drilling and sawing slurry directly into rivers, lakes or the sewerage system without suitable
pretreatment is problematic from an environmental point of view.
▶ Ask the local public authorities for information about current regulations.
We recommend the following pretreatment:
▶ Collect the drilling or sawing slurry (for example, using a wet-type vacuum cleaner).
▶ Allow the drilling or sawing slurry to stand for some time or add a flocculation agent to help the fine
particles in the slurry settle and separate from the water.
▶ Dispose of this solid portion of the drilling or sawing slurry at a construction waste disposal location.
▶ Neutralize the remaining water from the drilling or sawing slurry (alkaline, pH-value > 7) by adding an
acidic neutralizing agent or dilute it by adding a large quantity of water before allowing it to enter the
sewerage system.
