Integrated Systems for Industrial Waste Heat Recovery
Reusing industrial waste heat can significantly improve process profitability. We reduce your purchased energy demand – and simultaneously cut CO₂ emissions from energy production.
By harnessing industrial waste heat, your company can significantly enhance both cost-efficiency and energy performance. Calefa provides customized solutions that transform excess heat from production processes into a valuable resource and usable energy.
Waste Heat Recovery Brings Multiple Benefits
Waste heat is a valuable resource with a wide range of applications. By utilizing excess heat in internal industrial processes, for heating buildings, or by selling energy to district or local heating networks, industries have tremendous potential to boost their energy self-sufficiency.
Reducing emissions. Energy produced with non-combustion technology generates no CO₂ emissions. By recycling waste heat, the need to purchase new energy decreases. As a result, our customers experience a significant reduction in carbon dioxide emissions.
Maintained performance at lower cost. When waste heat is utilized, the same amount of energy is used – but less needs to be purchased. Recovering industrial waste heat increases energy autonomy and is highly cost-effective.
Enhanced Processes, Improved Working Conditions. We deliver faster throughput times, draft-free production spaces, better indoor air quality, and reduced waste in industrial operations. Integrated systems based on waste heat recovery often also improve the overall production environment.
Tailored Solutions for Diverse Waste Heat Sources
At the chemical industry company Kiilto’s facility in Lempäälä, Finland, waste heat generated during adhesive manufacturing processes is utilized to heat buildings within the factory area. During summer months, the industrial waste heat is delivered to the local energy company Lempäälän Lämpö’s district heating network.
The Finnish energy company Lahti Energia operates a 5 MW AmbiHeat heat pump facility that recovers waste heat from treated wastewater at 10 °C and upgrades it to 90 °C district heating using advanced heat pump technology.

Our Solution for Industrial Waste Heat Recovery
The AmbiHeat heat pump facility is a modular, customizable, turnkey energy system designed to utilize sources such as industrial waste heat.
Waste heat collected from industrial processes or wastewater treatment can be upgraded for reuse with Calefa’s heat pump solutions. The AmbiHeat facility can simultaneously harness multiple heat sources in addition to industrial waste heat.
5 Reasons to Reuse Waste Heat
1
You will save on energy costs as the need for purchased energy decreases.
2
CO₂ emissions are reduced because additional energy no longer needs to be produced through combustion.
3
Our systems typically pay for themselves within 1 to 5 years, with a return on investment ranging from 20% to 100%.
4
Operating expenses decrease which improves overall profitability.
5
By joining the energy ecosystem, you may even have surplus thermal energy available for resale.
“Calefa’s systems have significantly increased cooling capacity in our processes. Process consistency has also improved as cooling is now much more controlled. During the summer, we’re able to channel waste heat into the district heating network and even gain some financial benefit from it – whereas before, it all just escaped into the air and was lost.”

Industrial Waste Heat Recovery Without Risk
We deliver complete turnkey solutions and take full responsibility for every stage of the project. This includes the initial site assessment, savings calculations, system design, full implementation, and post-installation support.
No risk involved — we take full responsibility
Calefa’s model for waste heat recovery is secure. There are no gray areas in the energy utility’s scope of delivery where liability issues might be unclear. Calefa provides a turnkey solution — it’s remarkably straightforward.
How a project with Calefa progresses
1. Waste heat potential assessment
We assess the potential for utilizing waste heat directly on site. We identify the sources of surplus energy and evaluate how it can be recovered. We calculate the economic feasibility of the solution, including projected energy savings and payback period.
2. Identifying added value
Can production efficiency be improved or working conditions enhanced at the same time? In most cases, yes. Industrial processes are part of our core expertise, which enables us to support these aspects as well.
3. Recommended actions
We only recommend implementation if our calculations show the solution to be economically viable. In practice, this means a total system payback period of 1 to 5 years.
Industrial waste heat recovery system with financing options
An energy reuse system can be acquired with a cash flow–positive installment plan, meaning no budget allocation is needed for the energy investment. Alternatively, the system can be procured through a leasing agreement. Calefa will handle the financing application on your behalf.
A waste heat recovery system tailored to your needs
A carbon-neutral future is built through concrete actions.
Delivered as a complete solution, the energy recycling system is reliable and worry-free. You will receive clear and expert answers to all plant-related questions from a single point of contact.
