Situation

Wienerberger AG, whose head ofﬁ ce is in Vienna, has 221 plants

in 30 countries, making it the largest manufacturer of bricks in

the world. Its German subsidiary Wienerberger GmbH operates

a total of 20 plants. These include Wienerberger Ziegelindustrie

GmbH in Wefensleben in the State of Saxony-Anhalt which has

been run as a Poroton lining brick plant since 1991. A workforce

of 54 at this site produce high quality Poroton bricks made of

clay for use in the construction industry. Around 1,000 tons of

material are used every day.

Task

The clay which consists of two strata, the upper loam stratum

and the lower shale stratum is extracted from the company’s

own mine. After this it is stored temporarily on the site and then

mixed with external additives from a nearby paper factory and a

nearby power plant and placed in the so-called box feeder. From

the box feeding system the material is transported on conveyor

belts to the production area. There it is placed in mixers and

then formed into the required brick form before being ﬁ red at

very high temperatures to produce Poroton bricks. The brick

gets its striking red color during the ﬁ ring process as a result of

a chemical process. After cooling the bricks are packed on to

pallets, welded in foil and made ready for shipment.
