Krefeld

Krefeld still markets itself as Germany's city of silk, but one turn of the Rheinhafen swing bridge can stall freight traffic for up to 45 minutes. That tells you more about the modern city than the slogan does.

Krefeld has 236,997 residents, sits about 43 metres above sea level on the Lower Rhine, and belongs to the dense Rhine-Ruhr corridor rather than the tourist map of western Germany. The city itself stresses the geometry: barges from the Rheinhafen can reach Rotterdam, Antwerp, and Hamburg in a day. It also says the old silk economy left behind something more durable than civic branding. As textile production industrialised, demand for bleaching, washing, dyeing, and machinery helped create Krefeld's chemical and engineering base.

That inheritance still governs how money moves through the city. In January 2025 Krefeld Business launched a Smart Mobility project for the Rheinhafen and Chempark because companies kept flagging the swing bridge as a logistics choke point; when the bridge turns for ship traffic, the tailback often takes about 45 minutes to clear. By June 2025 the project had installed sensors on the bridge after measuring the full rotation cycle at about 15 minutes. At the chemical end of the same corridor, Covestro said in July 2025 that it was investing more than EUR 100 million in modernising chlorine production and air-cleaning systems at Krefeld-Uerdingen. The chlorine plant feeds Covestro's local MDI and Makrolon lines plus other Chempark partners, while the salt yard there handles well over 1,000 tonnes a day. Then in January 2026 the ThielemannGroup committed about EUR 35 million to a new 60,000-square-metre logistics campus beside the container terminal, with nearly 40,000 square metres of logistics space.

Krefeld behaves like an oyster reef. Reefs stay productive because old shells remain in place and give new organisms somewhere to settle. Krefeld's silk-era substrate still shapes where chemistry, freight, and warehousing can attach. That is path dependence reinforced by network effects and stabilized by negative-feedback-loops: once a city sells coordinated industrial handoffs, even its traffic data becomes part of the product.
