Stolberg is a city with over 800 years of history. Economically, the city near Aachen focuses on metal processing, glass and pharmaceuticals. In recent decades, the city of 60,000 inhabitants has also developed from a typical industrial city into a modern and environmentally friendly city with a distinctive profile as a tourism and service location. In order to offer the residents of Stolberg a good service, the responsible department of the city issued a call for tenders and commissioned Roland Prehm from ERA Group to optimise cleaning costs.
