As market leader and technology pioneer, we design and build sewage sludge drying plants with population equivalents ranging from 1 000 to several million.
Our customers - public and private, municipalities and industrial companies - rely on our decades of experience and pioneering role in the field of sustainable drying.
The concept is simple: The sewage sludge is placed in transparent drying halls, where the freely available solar energy extracts the water from the sludge in a simple and cost-effective way. Sophisticated ventilation technology and fully automated turning units additionally increase the drying performance.
Thanks to its high organic content, sewage sludge is ideally suited for use as an energy resource. Did you know that dried sewage sludge has a calorific value comparable to lignite? The drying process also reduces the volume of the sludge, which not only leads to considerable savings in transport costs and CO2 emissions, but also significantly reduces disposal costs.

Tailored solar drying concepts
We offer three different solar drying concepts to meet various operational requirements:
- SolarBatch: A batch process ideal for plants with high flexibility requirements.
- SolarFlow: A continuous process suitable for plants with a steady flow of material, with the option of full automation.
- StorageDryer: A semi-continuous process designed for smaller plants
Each concept uses the same basic principle: the use of solar energy to extract moisture from substrates, resulting in a significant reduction in volume and weight.
This not only reduces disposal and transportation costs, but also opens up opportunities for material reuse and recycling.
