Dust-Free Pellets Through Innovative Pelletizing Technology
Our custom-built, slow-speed forced-draft pelletizer reliably transforms dried sewage sludge into dust-free, durable pellets — significantly reducing the risks of dust explosions and health hazards.
From wet sludge handling to drying and logistics, our entire system is designed for emission-free operation. The dryer operates under vacuum to prevent emissions, and the dried sludge is transferred into a sealed container, where a fully automated pelletizing process takes place.
The result: high-quality, abrasion-resistant pellets that eliminate the need for complex silo storage or logistics — safe, clean, and efficient.
Less Volume, Fewer Truckloads – Maximum Efficiency with the STR System
Our STR drying system drastically reduces the volume of dewatered sewage sludge:
From an original 5,000 metric tons per year — requiring around 210 truck trips — the volume is reduced to just 1,389 metric tons annually after drying. That means only 58 truck trips are needed — with the same amount of material.
A clear win for the environment, logistics, and overall cost efficiency.
Versatile Use of Our Hygienized Sewage Sludge Pellets
Our hygienized sludge pellets are not only safe for open storage but also remarkably versatile in their applications. Thanks to a specially developed drying process, we produce a high-quality material ideal for both energy recovery and material recycling:
Incineration – used as an efficient, carbon-reducing alternative fuel with high calorific value
Gasification – for the production of syngas in industrial processes
Phosphorus Recovery – a valuable resource for the production of sustainable fertilizers
Fertilizer Use – direct application in agriculture, in compliance with applicable regulations
The hygienizing drying technology allows for open storage and flexible use of the pellets—contributing to a resource-efficient circular economy.
