Background

The profitability of biogas plants can often be improved significantly by utilising existing waste heat. However, remote heating concepts often fail because distances are too great, or because the heat received is insufficient or not continuous.

The available waste heat can be utilised much better to dry fermentation residue. This involves complete utilisation on site all the year round. Drying reduces the removal and storage costs, concentrates the nutrients, and increases the worth of the end product for transportation. Dried fermentation residue can also be sold as high-quality organic fertiliser. If the fermentation is from NAWARO plants, it can even be used in organic agriculture (as defined in the  EU Eco Standard).

Thanks to our experience in the construction of over 100 substrate drying plants, we can offer practical and particularly fault-resistant solutions for drying fermentation residue and sewage sludge. With its robust, low-maintenance, automated equipment, our technology is ideally suited for agricultural companies.
