Together with Huber SE located in Berching, WTE has founded the sludge2energy GmbH for innovative sludge utilisation concepts. The process is defined by a combined drying and thermal utilisation of sewage sludge in a fluidised bed furnace.
- Combined drying and thermal utilisation of sewage sludge in a fluidised bed furnace
- Modular design for throughputs from 4,000 to 7,000 t DS/a as single-line system, applicable for 200,000 up to 300,000 PE sewage treatment plants
- Auto-thermal (self-sustaining) combustion and drying, no external thermal energy required
- Low invest and operational costs due to the optimised concept of thermal drying and utilisation in a compact design
- Optimal sewage sludge quantity and mass reduction
- Minimised sewage sludge transport costs
- Long-term cost and disposal reliability
- Production of recycling material that can be reused for the most part (e.g. by construction industry)
- Dry flue gas cleaning process without the need for water and without generation of wastewater
- Low pollutant emissions, significantly below legal limits (e.g. BImSchG, TA Luft)
- Minimum space requirement
- Availability: 8,000 h/a
- Fully automatic operation 24 h/d, 7 d/week
- High flexibility of sewage sludge utilisation
- Production of phosphorus-rich sewage sludge ash, therefore optional phosphorus recycling
