History
Years, routine, experience:Environmental protection is a tradition with us
1990
PORR Umwelttechnik GmbH is founded with the aim of pooling PORR's expertise in the field of technical environmental protection.
The first project is called ‘Demolition and soil remediation of the Alder site’. The soil and demolition material from the former Victor Alder chemical factory in Vienna's 10th district are contaminated with cyanide levels that are dangerous in some cases. A semi-mobile soil washing plant from PORR Umwelttechnik is cleaning up the contaminated site.
1991
Participation in the project ‘Contaminated site remediation and spoil tip Langes Feld GmbH’. The contaminated site will be secured using the ‘Vienna slurry wall chamber system’ and the area will henceforth be used as a landfill site.
1993
The investment company ABW Abbruch-, Boden- und Wasserreinigungsgesellschaft m.b.H. is constructing a soil washing plant that can clean highly contaminated, hazardous waste of mineral origin.
1998
THORN Abwassertechnik GmbH joins PORR as part of Radmer Kies.
1999
PORR Umwelttechnik is constructing a stabilisation plant. This will make it possible to permanently reduce the hazards posed by physical and chemical changes in the waste.
2003
Integration of PORR Earthworks into PORR Environmental Technology: Earthworks and demolition activities now expand the service portfolio.
2006
With the establishment of the PWW Group, PORR Umwelttechnik enters the Serbian market. Two modern landfills, each with a capacity of 1.7 million m3, and two recycling centres are being built, enabling the collection and treatment of household waste in the Jagodina and Leskovac regions.
2011
PORR Umwelttechnik is expanding its business areas to include renewable energy, water supply and wastewater disposal.
2012
Acquisition of TKDZ GmbH in Wellen, Germany, which extracts dolomite rock from underground mines and refines it in above-ground facilities.
2013
The acquisition of the Prajo Group strengthens PORR Umwelttechnik in the demolition, transport and building materials recycling sectors.
2016
The majority takeover of the former affiliated companies ABW, Langes Feld, Koller GmbH and PKM Muldenzentrale enables even closer cooperation between the individual business areas and thus even more flexible services for customers.
The establishment of PORR Umwelttechnik Deutschland GmbH also focuses on demolition and pollutant remediation work in Germany.
2018
The Pirka recycling plant goes into operation. PORR Umwelttechnik is thus further expanding its building materials recycling business segment.
