Sorting Plants for Refuse Derived Fuel

Refuse derived fuels for cement production must be of consistently high quality. Our plants therefore preferably use mechanical separation processes.

STADLER experience

“From the first plant in 2005 to date, we have commissioned ten refuse derived fuel plants. According to our customers, each of the plants has more than satisfied expectations.”

Material properties

Our refuse derived fuel plants professionally process commercial waste as well as pre-sorted waste containing plastics, which serve to produce high-quality refuse derived fuels for cement production.

Example process description

In order to deliver high-quality refuse derived fuel for cement production, the material undergoes a complex treatment process. Pre-shredding, screening technology, ballistic separation, NIR and X-ray technology, ferrous and non-ferrous metal separators all serve to separate valuable materials and impurities. The high-quality refuse derived fuel is then re-shredded to the final size required by the cement manufacturer. This is subsequently transferred directly to the feeding system of the cement kiln. In order to supply the requisite quantities of refuse derived fuel for cement production at all times, we have integrated a spacious intermediate hopper with a powerful automatic crane into the system.
