Dust extraction during the transport of Refused Derived Fuels (RDF)

Refused Derived Fuels (RDF) are a type of secondary fuel produced mainly from energy-rich waste—such as plastics, textiles, wood, paper, and other combustible materials. They are primarily used in cement plants, incineration facilities, and other industrial operations as a substitute for fossil fuels.

Handling RDF generates significant dust, which can pose a threat to operator health, contaminate technology and the surrounding environment, and in some cases present an explosion hazard. The main sources of dust include:

• Material intake – e.g., during unloading from trucks, containers, or silos.

• Storage – loose storage of materials in warehouses or silos with the potential for dust dispersal.

• Transport – belt, screw, or pneumatic conveying systems generate dusty areas, especially at transfer points or route junctions.

Our solution: Filter units for RDF

Our company manufactures highly efficient filter units designed for dust extraction in Refused Derived Fuel transport systems. We cooperate with general contractors of industrial facilities, delivering filtration equipment tailored to specific projects.

Our units are designed for continuous operation in demanding industrial environments and feature:

• Wide spacing between filter elements – This ensures better airflow, lower pressure loss, and more effective filter regeneration.

• Use of antistatic (electrostatically conductive) filter media – These media are suitable for dusty environments with explosion risk, such as handling fine RDF dust.

• Filter regeneration with compressed air (so-called pulse regeneration) – An automated system ensures long filter life and minimal maintenance requirements.

• Design for explosive dust extraction (ATEX) – Filters can be equipped with passive or active explosion protection elements, such as pressure relief flaps, membranes, or extinguishing systems.

Our filter units help customers comply with emission limits, reduce workplace dust levels, and protect both operator health and technology. We provide full technical support—from design and production to commissioning.
