Abstract (en)
[origin: WO2013139959A1] The invention relates to a method for treating sludge in order to improve storage and/or transportation properties, characterised in that the sludge is converted into granules by adding a water-absorbent organic polymer material, with water-absorbent organic polymer materials, particularly super-absorbers and/or hydrogels, being used as additives. The invention also relates to granules that contain sludge as well as water-absorbent organic polymer materials, preferably super-absorbers and/or hydrogels.
