The view from the factory floor Beyond the data, the project delivered profound qualitative benefits. The MIXIT system provided a level of operational intelligence that was previously unattainable. "We can now control our heating system down to the smallest detail," stated Daniel Bagger, Facility Supervisor at Envases. This granular control empowers the management team to move from reactive maintenance to proactive, continuous optimization, fine-tuning the system in real-time to maximize both economic returns and environmental benefits. Scaling the model: From Odense to Europe. The Envases project is a proven pilot for a much larger European strategy, demonstrating a practical method for tapping into the 151 PJ of high-grade surplus heat near existing DH networks. The total annual energy contribution from this single factory is 37 GWh (approx. 0.133 PJ). A simple calculation reveals the power of replication: a portfolio of roughly 1,100 similarly sized projects could theoretically capture the entire 151 PJ of "low- hanging fruit." This reframes the solution not as a single mega- project, but as the mass replication of smaller, proven, local successes. Future-Proofing with 4th Generation DH This model is also aligned with the future of district heating, which is moving towards lower operating temperatures (4th Generation District Heating, or 4GDH). These advanced
product without requiring a team of specialist engineers. As noted by Envases Facility Supervisor Daniel Bagger, it makes sophisticated energy management accessible. Each MIXIT unit communicates wirelessly with a high-efficiency MAGNA3 / TPE3 circulator pump and can integrate with the factory's Building Management System (BMS) for centralized monitoring and control.
A trifecta of savings: Energy, emissions, and cost The project yielded remarkable, quantifiable results:
Energy recycled: The system captures and recycles 23 GWh of thermal energy annually, equivalent to the heat consumption of approximately 1,300 Danish households. This energy is now a valuable commodity sold to the DH grid. Energy saved: The system provides a further 14 GWh in direct energy savings for the factory's own operations, as captured heat displaces the need to purchase heat from the grid. CO2 abated: The combined energy savings of 37 GWh annually result in a direct reduction of 3,000 tonnes of CO2 emissions every year. This is roughly equivalent to the annual emissions from 670 gasoline-powered passenger vehicles.
