energy optimization
Energy-efficient operation and reduced heat emission
Glass manufacturing is one of the most heat-intensive industries. Melting furnaces, forming lines, tempering zones and cooling tunnels operate at extremely high temperatures – often continuously – and release substantial amounts of waste heat. The unused heat typically escapes via exhaust systems or flue gas.
With Exodraft’s heat recovery solutions, this energy can be captured and returned to the production process – for example, to heat process water, buildings, or domestic water. This enables more energy-efficient operations and reduces thermal emissions.
Whether you produce window glass, packaging glass, technical glass, or insulation materials, heat recovery can be integrated into your setup – without compromising product quality.

Why heat recovery is relevant for glass manufacturing
In glass production, raw materials are melted at temperatures exceeding 1,400°C, after which the glass is shaped, tempered and cooled under controlled conditions. These processes generate vast amounts of heat – especially from melting furnaces, hot forming tools, and cooling ducts – much of which is typically lost through flue gas or extraction.
At the same time, glassworks require significant energy for heating elsewhere in the production process – such as for process water, cleaning systems, and comfort heating in large production halls. Heat recovery offers a clear opportunity to balance thermal surpluses and heating demands internally within the business.
For glass manufacturers aiming to reduce their energy consumption and carbon footprint without compromising operational reliability or product quality, heat recovery presents both a practical and strategic solution.

Let us help you! – We custom solutions for recovering your waste heat, so you can optimize your energy efficiency for the benefit of both the environment and your business.
Can I recover my waste heat?
You can recover up to 95% of waste heat from process air, steam, and flue gases. The surplus energy can be stored or used directly to optimize production processes.
Why heat recovery is important
There are increasing demands for us to take responsibility in the green transition. With the right system, you can reduce your carbon footprint and costs.
Will the investment benefit my business
Our solutions not only enhance your green profile but also improve your financial bottom line. Typically, the investment pays off in 2-3 years.

How glass manufacturers utilise waste heat
Glass manufacturing generates waste heat at several stages: from melting furnaces and forming zones to cooling tunnels and post-processing areas. With Exodraft’s heat recovery systems, this energy can be efficiently captured – without disrupting sensitive parts of the process.
Typical applications include:
- Heating of production halls and technical rooms
- Heating of domestic water for cleaning, washing and sanitation
- Preheating of process water, e.g. for raw material preparation
- Absorption cooling – converting heat into cold for control rooms, warehouses and offices
- Export to district heating networks, where local infrastructure allows
- Strengthened ESG profile and CO₂ documentation
With proper system design, we ensure that the recovered energy is used where it creates the most value – without affecting glass quality or production stability.
