Abstract
Lorenz GmbH & Co. KG is a multi-award-winning medium-sized company that specialises in water meters, including wireless water meters. The residential water meters essentially consist of a plastic meter and a hydraulic system made of brass through which the water flows. Although the availability of brass as the main raw material is not at risk for the foreseeable future, the price has been subject to strong fluctuations over the last ten years with a tendency toward exceptionally high price increases. As a result of this cost factor, the industry has seen a trend towards replacing brass with apparently cheaper, but less durable plastic that is also more energy-intensive to manufacture.
