Tetra Pak launches Integrated Heat Pump system to electrify pasteurization and cut energy use by up to 77%
· New Tetra Pak® Integrated Heat Pump system delivers combined heating and cooling to pasteurization, enabling up to 77% energy savings while reducing CO₂ emissions and operating costs1
Lausanne, Switzerland, 26 November 2025 – Tetra Pak today announces the expansion of its Factory Sustainable Solutions portfolio with its new Tetra Pak® Integrated Heat Pump system for pasteurizers, designed to help food and beverage (F&B) producers reduce energy use and cut costs.
Pasteurization is a critical process for food safety and quality, but traditional systems are energy-intensive, typically relying on fossil fuels for heating and electrical chillers for cooling. As F&B producers seek to improve efficiency and sustainability, optimising energy use in this process offers a clear path to reducing both costs and emissions through smarter heat recovery and reuse.
The new Tetra Pak® Integrated Heat Pump system builds on the company’s existing pasteurization technology by introducing a high-efficiency electric heat pump that recovers and reuses heat from the pasteurization process. For every 1 kWh of otherwise wasted heat – making it up to three times more efficient than a traditional boiler1.
By combining heating and cooling in one integrated solution, the system also optimises energy use across the pasteurization process. It upgrades low-temperature waste heat to higher temperatures and generates ice water for cooling. This dual function helps lower total energy consumption and operating costs1, while supporting producers in reducing reliance on fossil fuels and exposure to volatile energy prices2.
F&B producers operating large scale pasteurization processes, such as fruit juice, chilled milk, cheese and ambient milk pre-treatment pasteurization, stand to achieve substantial savings. A typical dairy production line, for example, could reduce energy consumption for pasteurization by up to 77%, making operating expense (OPEX) savings of up to €230,000/year and reducing CO2 emissions by up to 650 tonnes/year.3
Nicole Uvenbeck, Director Factory Sustainable Solutions and OEM Components at Tetra Pak, comments: “Food and beverage producers need smarter ways to reduce energy use without compromising performance. The new heat pump system delivers up to three times the efficiency of conventional boilers, recovering 2 kWh of heat for every 1 kWh of electricity4. By combining deep processing expertise with a global network, we work closely with customers to select the right solution and ensure seamless integration into their operations, supporting their shift toward more resilient, energy-efficient production.”
Fiona Liebehenz, Vice President Key Components, Plant Solutions and Channel Management at Tetra Pak, comments: “We’re proud that our long-standing experience in developing processing solutions for the food and beverage industry, together with a strong focus on innovation, has led to another important step forward. By blending advanced technology with a deep understanding of the daily challenges F&B producers face, we’ve developed a solution designed to make one of the most energy-intensive stages of food production more efficient.”
