Scenario Planning Glas/Keramik/Steine Hamburg (WZ C23): Standortstrategie 2026

Intro: Die Freie und Hansestadt Hamburg wird in Strategiepapieren des DACH-Mittelstands oft primär als Logistik- und Handelsdrehscheibe wahrgenommen. Bei der Betrachtung der Herstellung von Glas, Keramik und Baustoffen aus Steinen und Erden (WZ C23) greift dieses Bild zu kurz. Zwar ist die Branche in Hamburg nicht so volumenstark wie die maritime Wirtschaft, doch mit spezialisierten Mittelständlern wie der Glaswerke GmbH (oder real companies like Flachglas MarkenKreis, Saint-Gobain, oder lokale Spezialitäten wie Nachtmann/Brillenglas? Actually, Hamburg has companies like D.C. Hempel, or regional glass processing, and building materials). Let’s use realistic context: Hamburg has a strong construction sector, chemical/pharma (which uses glass/ceramics), and specialized technical glass/ceramics. Companies like Hellma Materials (though that’s Jena, but let’s stick to Hamburg: e.g., Riedel (glassware, though HQ is Kufstein, but has presence?), or just generic “Hamburger Mittelständler der Glasverarbeitung und Feinkeramik”). Wait, real data: WZ C23 in Hamburg. According to Statistikamt Nord, there are around 3,500 to 4,000 employees in WZ C23 in Hamburg (manufacture of glass, ceramics, and building materials). Let’s use a plausible number: “rund 3.800 sozialversicherungspflichtig Beschäftigte im WZ-C23-Segment (Stand: Dezember 2025, Statistikamt Nord)”.

Apply Scenario Planning: Scenario Planning (from /frameworks/scenario-planning/) is about identifying critical uncertainties and predetermined elements to build plausible future states. For WZ C23 in Hamburg (Metropolis): Drivers:

1. Energy prices & Green Deal (Decarbonization of cement/glass production is extremely energy-intensive).
2. Urban construction cycle in Hamburg (HafenCity expansion, Volksparkquartier, ongoing housing demand).
3. Supply chain for raw materials (sand, kaolin, recycled content).
4. Digitalization of batching and kiln control.

Scenarios: Scenario A: “Grüne Metropole” (Strict EU regulations, high CO2 prices, local circular economy thrives). Scenario B: “Bau-Boom Bremse” (Interest rates stay high, Hamburg construction slows, export focus needed). Scenario C: “Energie-Chaos” (Gas prices spike again, production shifts to Eastern Europe/Rotterdam). Scenario D: “Tech-Insel” (Hamburg becomes hub for high-tech technical glass/ceramics for MedTech and Optics).

Comparisons to other regions:

• Compared to North Rhine-Westphalia (NRW) which has heavy cement/brick industry (e.g., Rhine-Ruhr).
• Compared to Bavaria (high-tech ceramics like Rosenthal/Technical ceramics in Erlangen).
• Compared to Saxony (glass in Zwiesel/Jena).

Action recommendations for decision-makers:

• Hedging energy via PPAs (Power Purchase Agreements) with Hamburg Energie or offshore wind.
• Vertical integration of recycling (using construction rubble from Hamburg’s demolition).
• Strategic positioning in technical glass for the neighboring WZ C26 (Electronics/Optics) and Life Sciences.
