10 Disposal
Most of the materials from which Hilti products are manufactured can be recycled. The materials must be
correctly separated before they can be recycled. In many countries, your old tools, machines or appliances

Drilling slurry
Disposal of drilling slurry directly into rivers, lakes or the sewerage system without suitable pretreatment
presents environmental problems.
▶ Ask the local public authorities for information about current regulations.
We recommend the following pretreatment:
▶ Collect the drilling slurry (for example, using a wet-type vacuum cleaner).
▶ Allow the drilling slurry to settle and dispose of the solid material at a construction waste disposal site
(addition of a flocculent may accelerate the settling process).
▶ The remaining water (alkaline, pH value greater than 7) must be neutralized by the addition of an acidic
neutralizing agent or diluted with a large volume of water before it is allowed to flow into the sewerage
system.
