Waste heat recovery
Turn your heat losses into competitive low-carbon heat. Newheat identifies and develops your waste heat resource, from feasibility study to supply.
solution
What is waste heat recovery ?
Every industrial process generates heat that it does not consume: hot flue gases, cooling water, unrecovered steam. This residual heat, known as waste heat, is released into the environment without being used. Yet it represents a thermal resource that you can harness directly on site.
Recovering it means capturing it before it is dissipated and reusing it where it is needed: supplying a district heating network, preheating process water, or heating industrial buildings.
How can waste heat from industrial processes be recovered?
Heat is captured at source via heat exchangers installed on industrial flue gases, cooling circuits or process effluents. It is then transported by hot water, hot air, steam or thermal oil, to the point of use.
Depending on the available temperature and the end customer’s requirements, the system may incorporate:
- a heat pump, to raise the temperature of the waste heat to the required level,
- a thermal storage tank, to balance out fluctuations between production and consumption,
- a direct connection to a district heating network or another process on site, without any further conversion.
Who can make the most of their waste heat?
The sites most likely to benefit are those whose processes operate continuously and generate waste heat at temperatures ranging from 20°C to 300°C: food processing, malting, paper manufacturing, cement production, glass manufacturing, chemicals, metallurgy, data centres, wastewater treatment, etc.
The recovered heat can be used on-site by the industrial operator itself, or supplied to a nearby district heating network.
Our customer benefits
How you benefit from utilising your waste heat
Reduce your energy bill
Waste heat costs nothing to produce. Every MWh of waste heat reintroduced into your process replaces one MWh of gas that you no longer need to purchase.
Decarbonise without changing your process
Your CO₂ emissions (Scope 1 or 2) are reduced directly, without altering your production lines or slowing down your operations. It is one of the quickest decarbonisation measures to put into action.
Securing your energy supply
Recovering your waste heat reduces your dependence on fossil fuel markets and their volatility.
Accessing public funding
Waste heat recovery projects can benefit from national and European public support schemes (CEE, ADEME’s Heat Fund, Innovation Fund, RRF), which significantly improve the project’s cost-effectiveness.
Does your industrial site consume heat?
We can help you manage your heating costs and implement low-carbon waste heat recovery solutions to replace fossil fuels.
NEWHEAT’S SUPPORT
How Newheat operates, from source to supply
Newheat develops, finances, builds and operates waste heat recovery installations. We are involved throughout the entire project; whether you are at the feasibility stage or your project is already defined, we step in where you need us, from design to operation, whilst ensuring the long-term competitiveness and performance of the solutions.
Audit and assessment of potential
You have identified a heat source on your site but are not yet sure of its value. We map your heat flows, identify collection points on your flue gases or cooling circuits, and assess the technical and economic feasibility of your project.
Design and implementation
Your project has been defined and you are looking for a partner to build it. Newheat designs and implements the installation, with performance commitments set out in the contract from the moment it is signed. Depending on your needs, we can also arrange the financing.
Operation and maintenance
We manage, maintain and optimise your heat recovery system throughout the contract period, with guaranteed availability rates and annual thermal performance. You receive low-carbon heat without having to manage the system.
Let’s assess the decarbonisation potential of your site or heating network
Newheat provides you with renewable heat that is cheaper than your current solution, with a price indexed to the market of your choice: electricity, biomass or a sector-specific index. This allows you to maintain control over your costs and competitiveness.
Whether your project is at the planning stage or already underway, we can assist at whatever stage you need us, from development through to the operation of the facility.
