About us

DHZ is running the supersort®technology plants which are located in the environs of Zurich Airport.

DHZ was created in December 2009 in order to build and run the Häuli landfill near Lufingen. The headquarter is also located near Lufingen.

Clean processed

We regaine raw material and resources for the community and the environment. Resource mining® stands for the integral consideration of the material cycle. supersort®technology plants recover valuable resources out of wastes and returns high quality raw materials back into production and so into the ressource cycle.

Safely disposed

Through advanced technology we guarantee a clean and safe separation of the residue fraction from the groundwater and from the environment. We only dispose what is according to the law and what can’t be recycled.

Sustainable active

We stay dedicated on a long term basis to our customers. We are commited to our resource mining® strategy from the construction of the landfill to the recultivation and from the treatment of the wastes to the recoverd metals.
