Environmentally sound recycling technologies can revolutionise production processes and can also save rare as well as expensive resources and improve product quality: The company Süß Oberflächen GmbH saves 20,000 € per year and additionally increases product quality by recovering acid from the anodising bath. In addition, the engineers save a quarter of the energy and 90% of the water by applying smart process technology.
Three companies – three examples of resource efficiency: In foundry business quality and material savings do not exclude each other. Wine jelly spread is heated and cooled down with more efficient technology in a family business. A surface finishing company combines product quality and resource conservation.
teamtechnik — a mechanical engineering company active in the fields of automotive, medical devices and solar technology — not only utilizes compressed air to manufacture their systems. The company’s customers also use this volatile form of energy to operate the teamtechnik systems and to produce the suction air required for operation. Thus the Swabian machine manufacturer not only implements several measures in the own enterprise. The application of an innovative ejector, which produces suction air, enables the system operators to efficiently provide the system’s vacuum gripper with the required energy and to precisely control the work processes up to a fraction of a second.
The Blechwarenfabrik Limburg produces more than 80 million metal packaging units each year – cans, round and square-cut, small and large, mainly for the coating industry. For this purpose, the company needs more than 21 thousand tons of tinplate each year – this corresponds to the weight of three Eiffel towers. A new gantry press makes better use of the tinplate surface to be cut out and therefore helps the company save 800 tons of the raw material each year. Furthermore, the company uses special film lamination plants; thus for a part of the cans coating is no longer required. This saves energy and lacquer as a raw material. The technology is also transferable to other fields of application that require coating.
Paints were already used 7500 years ago. Even then, the Chinese used the bark of a special tree as a binding agent for a paint coat. Today, paints serve, among others, to protect steel and plastic surfaces, to design them in different colors and to provide them with defined physical properties. Often, painting is the last step in a complex production process. And this is precisely where the potential for big savings in energy and raw materials, i.e. paint, is often ignored – a not insignificant potential companies could easily tap by means of simple organizational and/or technical measures.
