Waste treatment plants

Construction waste recycling plants in Himberg and Pirka.

As resource-efficient construction becomes ever more prevalent, the use of recycled building materials is becoming increasingly important in the construction industry. The Austrian Recycling Building Materials Regulation (Recycling Baustoffverordnung or RBV) has created the framework conditions for this.

The Himberg building material recycling plant operated by our affiliate RCH Recycling Center Himberg has been processing between 350,000 and 400,000 tonnes of construction waste of various origins every year for some time now.

To meet the growing demand, PORR Umwelttechnik has now set up a stationary construction waste recycling plant in Styria as well. The new plant in Graz-Pirka is designed for an output of 150t/h. High-quality recycled products are produced from mineral construction waste by crushing, sorting, classifying and wet processing. The plant in Pirka processes a total of 180,000 tonnes of construction waste per year. The recycled products are then reused. With the construction of this recycling plant, PORR Umwelttechnik has taken a step towards sustainability and environmental protection in Styria – and a step towards the future.

Waste stabilisation.

PORR Umwelttechnik’s stabilisation plant makes an important contribution to protecting our environment. Its function is the efficient treatment of hazardous and non-hazardous waste. Problematic substances must be landfilled or incinerated sustainably and safely.

After the previously loose or powdered waste has been mixed with aggregates and water, the materials are homogenised in the batch mixer. In this form the waste can be landfilled without any problems. Another field of application lies in the possibility of subjecting the corresponding waste fractions to thermal waste treatment after treatment.

For more information on waste stabilisation, please see the ABW Abbruch, Boden- und Wasserreinigungsges.m.b.H.

Soil washing plant.

The ABW Abbruch, Boden- und Wasserreinigungsges.m.b.H. soil washing plant is a physiochemical waste treatment plant. It is used to treat liquids and disperse solids such as excavated soil, demolition material or industrial waste.

The main function of the soil washing plant is to treat materials contaminated by inorganic or organic pollutants and to recycle individual components. Inorganic pollutants include cyanides, heavy metal salts and chromates. Mineral oils, PAHs, PCBs and phenols are organic pollutants.
