The Frozen Frontier: How Florida Eis is Engineering the World’s First CO2-Free Ice Cream Factory

SCHÖNEBECK, GERMANY – In the landscape of global manufacturing, the transition to "green" energy is often discussed in terms of decades and incremental percentages. However, for Olaf Höhn, the 76-year-old visionary behind the Berlin-based artisanal brand Florida Eis, the future of carbon-free industry is not a distant goal—it is a construction project scheduled for groundbreaking on August 20, 2026.

With an investment of approximately €25 million, Höhn is set to build the world’s first entirely CO2-free ice cream factory in Schönebeck, near Magdeburg. This project represents the culmination of a life’s work that has blended traditional craftsmanship with radical mechanical engineering, aiming to prove that even the most energy-intensive industries can operate in total harmony with the environment.

I. Main Facts: A New Benchmark for Sustainable Industry

The project in Schönebeck is not merely a factory expansion; it is a technological manifesto. While many companies purchase "carbon offsets" to claim neutrality, Florida Eis green is pursuing true carbon-free operation through architectural innovation and energy autarky.

Key Project Specifications:

• Location: Wilhelm-Dümling-Straße, Schönebeck (Salzlandkreis), Saxony-Anhalt.
• Investment: Approximately €25 million, supported by state "Cleantech" subsidies.
• Energy Goal: 98% to 100% energy autarky.
• Infrastructure: Three massive halls constructed primarily from sustainable timber.
• Employment: Initially 100 jobs, with a long-term goal of 250 employees.
• Core Innovation: Integration of on-site wind turbines, extensive photovoltaic arrays, and hydrogen production for logistics.

The Schönebeck facility will build upon the successes of Höhn’s existing "green" factory in Berlin-Spandau, which has operated CO2-neutrally since 2013. However, the new site aims to close the final gaps in the carbon cycle, including the localized production of raw materials and the elimination of fossil fuels from the supply chain.

II. Chronology: From Silent Cinema to Carbon Neutrality

To understand the scale of the Schönebeck ambition, one must look back at the century-long evolution of the brand.

1927–1984: The Artisanal Roots

The story began in the foyer of the Concordia silent film cinema in Spandau. There, the Blotko family served vanilla and strawberry ice cream from one of Berlin’s first drum ice cream machines. For decades, the business remained a local staple, surviving the destruction of World War II and the subsequent reconstruction of Berlin.

1984: The Engineering Pivot

Olaf Höhn, a mechanical engineer by trade, took over the business in 1984 following a professional dispute with his family’s bakery business. Alongside master confectioner Simone Gürgen—who had previously crafted desserts for legendary conductor Herbert von Karajan at the Hotel Kempinski—Höhn rebranded the business as "Florida Eis."

The early years were fraught with financial instability. Höhn recalls years where the deficit was so high he couldn’t afford a family vacation. However, by focusing on quality and expanding from a single café to a multi-site operation, the brand eventually gained a foothold in the competitive German dessert market.

2013: The Spandau "Green" Revolution

The turning point for the company’s environmental mission occurred in 2013 with the construction of a new manufacturing plant in Berlin-Spandau. Höhn’s initial goal was modest: installing solar panels on the roof. However, his engineering instincts took over. He began redesigning the entire thermodynamic cycle of ice cream production. This facility eventually grew to 4,000 square meters, yet, remarkably, maintained the same energy costs as the company’s previous 600-square-meter workshop.

2026–2027: The Schönebeck Vision

The upcoming Schönebeck plant is designed to be the "final masterpiece" for Höhn. Scheduled for a 2027 opening, it represents the first time Florida Eis has expanded its production footprint outside of Berlin, choosing Saxony-Anhalt for its favorable "Cleantech" support and available space for renewable infrastructure.

III. Supporting Data: The Engineering of a CO2-Free Factory

Ice cream production is notoriously energy-heavy. It requires immense heat for pasteurization and extreme cold for shock-freezing and storage. Traditionally, this is achieved through massive electricity consumption and fossil-fuel-powered boilers. Höhn’s Schönebeck project disrupts this model through a "systemic" approach to thermodynamics.

The Energy Mix

The factory will be powered by a combination of:

1. Photovoltaics: Every available roof surface on the three timber halls will be covered in high-efficiency solar modules.
2. Wind Energy: At least two dedicated wind turbines will be erected on-site to provide power during non-sunny hours.
3. Hydrogen Electrolysis: Surplus energy from the wind and solar arrays will be used to produce green hydrogen on-site. This hydrogen will fuel the heavy-duty trucks responsible for transporting ice cream between Schönebeck and Berlin.

Adsorption Cooling and Waste Heat

A centerpiece of the technical design is the adsorption cooling system. Unlike traditional compression chillers that use electricity to create cold, adsorption chillers use thermal energy (heat). By capturing waste heat from production processes and solar thermal energy, the factory can generate the cooling required for the storage of ice cream with minimal electrical input.

Passive Insulation and Permafrost

The factory will utilize glass foam gravel—a material made from recycled glass—as insulation beneath the deep-freeze cells. This creates a "passive permafrost" floor, eliminating the need for the electric floor heating systems typically used in industrial freezers to prevent the ground from cracking due to frost heave.

The Circular Vanilla Greenhouse

In perhaps the most innovative use of waste heat, Höhn plans to build an on-site greenhouse to cultivate Vanilla planifolia. Vanilla requires a constant temperature of 26°C and 96% humidity. By utilizing the secondary heat generated by the adsorption cooling system, Florida Eis will produce its own vanilla in Germany, significantly reducing the carbon footprint associated with importing beans from Madagascar or Reunion.

IV. Official Responses: Political and Regional Support

The Schönebeck project has become a focal point for regional economic development in Saxony-Anhalt.

Bert Knoblauch (CDU), Mayor of Schönebeck, has championed the project since its announcement in late 2025. "This settlement is highly sought after in our region," Knoblauch stated, noting that the combination of high-tech jobs and a public-facing café and playground makes the factory a community asset rather than just an industrial site.

Dennis Helmich, State Chairman of the Green Party (Bündnis 90/Die Grünen) in Saxony-Anhalt, emphasized the role of state policy in making such projects viable. He noted that the state’s energy agency (LENA) and specific Cleantech funding programs were essential in reducing the investment risks for Höhn. "For companies like Florida Eis, these instruments are indispensable for bringing new technologies to market," Helmich said.

However, the project also sits at a political crossroads. Helmich warned that proposed policy shifts from the AfD—which include cutting subsidies for renewables and abolishing the LENA agency—could jeopardize the "standort" (location) conditions that make such innovative factories possible.

Olaf Höhn himself remains focused on the democratic and social implications of his business. He describes himself as a "democrat and world citizen with a pacifist outlook." His business model includes social considerations, such as addressing the housing needs of his employees, many of whom are refugees or commuters from Berlin’s outskirts.

V. Implications: A Blueprint for the Global Food Industry

The success of Florida Eis green in Schönebeck could have profound implications for the global food manufacturing sector, which is currently under pressure to meet stringent ESG (Environmental, Social, and Governance) targets.

1. Breaking the "Premium" Price Barrier

A common criticism of green technology is that it inflates consumer prices. Florida Eis argues the opposite. By achieving nearly 100% energy autarky, the company insulates itself from the volatility of global energy markets. As Höhn demonstrated in Spandau, expanding production six-fold while keeping energy bills static is the ultimate competitive advantage.

2. Scalability of Adsorption and Hydrogen

The Schönebeck facility serves as a "living lab" for technologies like adsorption cooling and on-site hydrogen logistics. If these systems can be integrated successfully in a medium-sized enterprise, they can be scaled to larger industrial players in the dairy, frozen food, and pharmaceutical industries.

3. Sustainable Logistics

The move toward eutectic plate cooling in delivery trucks—which act like giant "cold batteries" charged at the factory—demonstrates a viable path for urban logistics. Combined with on-site hydrogen production for long-haul routes, Florida Eis is providing a comprehensive roadmap for a fossil-free supply chain.

4. Regional Revitalization

By choosing Schönebeck over more established industrial hubs, Höhn is proving that the "Green Revolution" can be a driver for economic renewal in East German regions. The planned addition of a children’s playground, a public café, and a greenhouse transforms the factory from a closed industrial block into a transparent, educational landmark.

Conclusion

When the first stone is laid in Schönebeck on August 20, 2026, it will mark more than just the start of a new factory. It will be a test of whether the "positive thinking" of an engineer-entrepreneur can overcome the systemic inertia of the fossil fuel era. Olaf Höhn’s vision suggests that the path to a CO2-free future is not paved with sacrifices, but with smarter engineering and a commitment to circularity. As the first scoops of Schönebeck-produced vanilla ice cream are served in 2027, the world may well be looking at the new standard for industrial production.
