Years, practice and experience. Environmental protection has a long tradition at PORR.

PORR Umwelttechnik GmbH is founded with the aim of pooling the PORR Group’s environmental engineering expertise.
The first project is called “Demolition and soil remediation at the Alder-Gründe”. The soil and demolition rubble of the former Victor Alder chemical factory in the 10th district of Vienna were contaminated with cyanide, in some places at dangerously high levels. The contaminated site was cleaned by PORR Umwelttechnik using a semi-mobile soil washing plant.

Participation in the project “Remediation of contaminated site and landfill 
Langes Feld GmbH”. The contaminated site is secured using the “Viennese sealed wall chamber system” and the area is henceforth used as a landfill.

The associated company ABW Abbruch-, Boden- und Wasserreinigungsgesellschaft m.b.H. sets up a soil washing plant capable of cleaning highly contaminated hazardous waste of mineral origin.

THORN Abwassertechnik GmbH joins PORR as part of Radmer Kies.

PORR Umwelttechnik builds a stabilisation plant. This makes it possible to permanently reduce the risks caused by physical and chemical changes in the waste materials.

Integration of PORR Erdbau into PORR Umwelttechnik: E
arthworks and demolition activities are added to the service portfolio.

PORR Umwelttechnik enters the Serbian market with the founding of the PWW Group. Two modern landfills, each with a capacity of 1.7 million m3, and two recycling centres are built to collect and process household waste in the Jagodina and Leskovac regions. 2011 PORR Umwelttechnik expands its business segments to include renewable energy, water provision, and wastewater disposal.

Acquisition of TKDZ GmbH in Wellen, Germany, which mines dolomite rock in underground mines and refines it in aboveground facilities.

With the acquisition of the Prajo Group, PORR Umwelttechnik strengthens its position in the demolition, transportation and building materials recycling sectors.

The majority takeover of the former associated companies ABW, Langes Feld, Koller GmbH und PKM Muldenzentrale facilitates even closer cooperation between the individual business segments and thus even more flexible services for our customers.
The foundation of PORR Umwelttechnik Deutschland GmbH also places a strong focus on demolition and site remediation in Germany.

The Pirka recycling plant begins operations. This represents a further expansion of PORR Umwelttechnik’s building material recycling business segment.
