appliances that have reached the end of their life must be collected separately and
returned to an environmentally compatible recycling facility.
▶
Disposal of electric tools or appliances together with household waste is not
permissible.
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.
