Germany’s Growing Demand for Energy-Efficient Continuous Drying
Germany represents a technically advanced market for industrial drying equipment, particularly where energy efficiency, waste utilization, emissions control and process reliability are important.
For industries processing biomass, wood products, sewage sludge, food ingredients and specialty chemicals, conventional high-temperature drying can result in significant thermal losses. This has increased interest in low-temperature belt dryers and continuous band drying systems, particularly when waste heat or other low-grade thermal energy is available.
The German market is especially relevant for two applications:
Biomass Drying → Pelletizing / Briquetting / Energy Recovery
and
Sewage Sludge Drying → Thermal Treatment / Resource Recovery / Phosphorus Recovery
Germany’s sewage-sludge regulations are also pushing the industry toward thermal treatment and phosphorus recovery. The German Environment Ministry states that phosphorus-recovery requirements apply from 2029 at the latest for relevant sludge streams.
This creates a strong technical case for efficient industrial belt dryers in Germany.
Why Belt Dryers Fit the German Industrial Environment
A Band Dryer, also called a belt dryer, mesh belt dryer or conveyor dryer, continuously transports material through a controlled drying chamber.
Unlike a simple batch dryer, the system can be divided into multiple drying zones.
Typical process
Wet Material
↓
Controlled Feeding
↓
Pre-Drying
↓
Main Drying
↓
Final Moisture Adjustment
↓
Cooling / Discharge
The drying profile can be adjusted through:
- Air temperature
- Air velocity
- Belt speed
- Residence time
- Recirculation
- Exhaust-air control
- Product layer thickness
This makes belt drying particularly attractive for materials that benefit from gentle, controlled and continuous moisture removal.
Germany’s Two Major Band Dryer Opportunities
1. Biomass, Wood Chips & Pellet Production
Germany’s biomass industry provides an important application for industrial belt drying.
Materials such as:
- Wood chips
- Sawdust
- Bark
- Wood residues
- Energy wood
- Biomass blends
often require moisture reduction before downstream processing.
Drying can prepare biomass for:
Drying → Pelletizing → Briquetting → Combustion → Gasification → Other Thermal Processes
Industrial belt dryers can be particularly useful when the process can utilize low-temperature heat or recovered energy.
A current German example illustrates the direction of the market: a pellet plant in Kerkingen commissioned a new low-temperature belt dryer in April 2026, with the manufacturer reporting an 18 t/h drying output and specific heat consumption of 450 kWh per tonne of pellets.
This demonstrates why energy efficiency is becoming a key purchasing factor rather than simply dryer capacity.
2. Municipal Sewage Sludge Drying
Germany is also an important market for sewage sludge belt dryers.
The country’s wastewater sector produces substantial quantities of sludge, and the regulatory framework is increasingly focused on thermal treatment and phosphorus recovery.
According to Germany’s Federal Environment Agency, approximately 1.8 million tonnes of municipal sewage sludge have historically been generated annually, with the majority already undergoing thermal treatment rather than agricultural use.
The transition is becoming even more significant as phosphorus recovery requirements approach.
Typical process
STP / Wastewater Treatment
↓
Mechanical Dewatering
↓
Wet Sewage Sludge
↓
Belt Dryer
↓
Dried Sludge
↓
Mono-Incineration / Thermal Utilization / Resource Recovery
Germany’s official environmental data also shows that sewage sludge is generally dried before subsequent disposal or thermal utilization when required.
Why Low-Temperature Belt Drying Is Attractive for German Plants
One of the strongest advantages of a belt dryer is its ability to work with relatively low-temperature heat sources, depending on the application.
Potential heat sources include:
- Waste heat
- Hot water
- Steam
- Thermal oil
- Hot gas
- Heat recovery systems
This is particularly relevant to German plants where an existing process may already generate recoverable thermal energy.
For example, industrial belt-dryer systems are commercially used for biomass, sludge and alternative fuels with options for partial or full air recirculation and waste-heat utilization.
Energy optimization can involve:
Waste Heat Recovery
→ Reuse available thermal energy instead of generating all heat from a new fuel source.
Air Recirculation
→ Recycle suitable portions of heated process air.
Multi-Zone Drying
→ Adjust temperature and airflow according to the product’s drying stage.
Thermal Insulation
→ Reduce unnecessary heat losses.
Variable-Speed Drives
→ Adjust fans, conveyors and feed systems according to actual production conditions.
The actual energy performance should always be established from material-specific drying calculations, rather than assuming a fixed percentage of savings.
Band Dryer Applications Across Germany
The opportunity extends beyond biomass and sludge.
Potential applications include:
- Vegetables
- Herbs
- Fruits
- Potato products
- Food ingredients
- Plant-based materials
Specialty Chemicals
Belt dryers can be evaluated for suitable:
- Granules
- Crystals
- Chemical intermediates
- Industrial salts
- Specialty materials
Applications include:
- Wood chips
- Sawdust
- Biomass pellets
- Agro-residues
- Alternative fuels
Wastewater & Environmental Technology
Potential applications include:
- Municipal sewage sludge
- Industrial sludge
- Dewatered sludge
- Organic residues
- Waste-derived materials
German Sewage Sludge Regulations Make Drying More Strategic
Germany’s sewage-sludge policy is an important differentiator from many other markets.
The German Sewage Sludge Ordinance restricts soil application of sludge from larger treatment plants after transitional periods, while phosphorus recovery becomes mandatory for relevant sludge streams from 2029.
This means drying is increasingly connected to a larger process objective:
Sludge Dewatering
→ Thermal Drying
→ Incineration
→ Ash Processing
→ Phosphorus Recovery
The German Environment Agency’s recent work specifically evaluates available thermal treatment and phosphorus-recovery capacity ahead of the 2029 transition.
Therefore, a sludge belt dryer in Germany should not be evaluated as an isolated machine. It should be considered as part of the plant’s complete sludge-management and resource-recovery strategy.
Belt Dryer vs Rotary Dryer in Germany
The right dryer depends on the material.
| Requirement | Band / Belt Dryer | Rotary Dryer |
| Low-temperature drying | Excellent | Moderate–High depending on design |
| Waste-heat utilization | Excellent potential | Possible |
| Biomass | Excellent for suitable feedstocks | Excellent |
| Sewage sludge | Strong application | Also possible |
| Minerals & sand | Limited depending on feed | Excellent |
| Gentle drying | Excellent | Moderate |
| Multi-zone control | Excellent | Possible |
| Fine moisture control | Excellent | Good |
| Very coarse bulk solids | Good depending on design | Excellent |
| Continuous operation | Yes | Yes |
There is no universally “best” dryer.
For German projects, the choice should be based on feed moisture, particle size, thermal sensitivity, available heat source, final moisture and downstream process.

Frequently Asked Questions
What is a band dryer used for in Germany?
Band dryers can be used for suitable biomass, wood products, sewage sludge, food products, chemicals and other continuous drying applications. The exact suitability depends on feed characteristics and required final moisture.
What is a low-temperature belt dryer?
A low-temperature belt dryer uses controlled warm air and extended residence time to remove moisture while limiting product temperature. It can be particularly attractive when waste heat or low-grade thermal energy is available.
Are belt dryers suitable for sewage sludge?
Yes. Belt drying is an established approach for suitable dewatered sewage sludge. Germany’s environmental documentation includes numerous sludge-drying installations using belt-dryer technology.
