1977: Construction of main production facility in Velbert

Extending product range to include drum screening machines, shredders, and verge mowers

“When I joined the company in 1980, there were only two of us in the factory – now there are hundreds working here!” recalls Peter Müller, who personally experienced the company’s growth.

By 1977, the farm in Homberg had definitely become too small: The Doppstadts then bought the property in Velbert in order to build their main production facility there. In addition, the company extensively extended its product range to include: verge mowers, high-speed shredders and drum screening machines to supplement its cleaning machines and gravel processors. In other words, machines that could shred and separate or sort building rubble, debris, wood and cut grass for recycling purposes.

Thus, the company’s focus had become clear. Doppstadt has become an environmental technology specialist. And begins to grow. “When I joined the company in 1980, there were only a handful of people working at Doppstadt,” recalls Peter Müller, a long-time employee at the company. “There were only two of us in the factory.” Nowadays there are about 700 people working for the company. “Of course, a lot has changed in the meantime,” says Müller. “When I worked at Doppstadt, the boss himself would come in the factory and discuss his plans with us.” While reminiscing, he also added: “One day, he wanted, for instance, to completely redesign the filter basin cleaning machine. But we were not able to envision his idea. That is when he grabbed a piece of chalk and started to sketch his ideas out on the floor of the factory. He then ordered us: ‘No one is to sweep here until I say so.’” The machine that was built on the basis of this sketch has been continuously adapted to the current state of technology – and is still in use to this day.
