Paper Sludge Drying with Belt Dryers from Hans Binder
Drying paper sludge is a challenge for many companies – high volume, high costs, and limited disposal options. With a belt dryer from Hans Binder Engineering, a costly waste material is transformed into a valuable energy source or raw material.
1. Why Paper Sludge Drying is So Important
Paper sludge typically contains between 50 and 70% water. This high weight drives up transport and disposal costs. Targeted drying can significantly reduce mass and volume – making disposal easier and substantially more cost-effective.
2. Efficient Use of Waste Heat
A decisive advantage of Hans Binder belt dryers is their energy efficiency. The systems operate with low-temperature heat in the range of 60–90 °C, which originates, for example, from power plants, biogas plants, or wood boilers. This allows existing energy sources to be optimally utilized – without the additional use of fossil fuels.
3. Uniform & Gentle Drying
Our belt drying systems ensure homogeneous residual moisture throughout the entire material flow. The gentle process prevents overheating – a crucial factor in preserving the fiber structure of the paper sludge. This makes it suitable for both material and energetic utilization.
4. From Waste to Valuable Material
Instead of costly disposal, paper sludge drying opens up new value creation potentials. Dried sludge can be used as fuel in cement plants or combined heat and power plants. The calorific value increases from 2–4 MJ/kg in the wet state to 10–14 MJ/kg after drying – an enormous gain in energy efficiency.
5. Reduced Emissions and Odors
Another advantage: Drying reduces microbiological activity. This means less odor nuisance during storage and transport. Emissions during subsequent combustion are also significantly lower due to the reduced water content.
6. Economical & Sustainable
With a Hans Binder belt drying system, disposal and transport costs can be reduced by up to 50%. At the same time, companies contribute to the circular economy and CO₂ reduction by utilizing the paper sludge energetically or materially.
Conclusion: Paper Sludge Drying Pays Off
Drying paper sludge is not only a technical necessity but also an economic advantage. Thanks to modern belt dryers from Hans Binder Engineering, cost factors are transformed into valuable materials – efficiently, sustainably, and future-proof.
