A sorbing granular material (20) is provided including a plurality of particles of granular material (5). The particles of granular material (5) are mixed at least partly with magnetizable particles (10), so that in case of magnetization of the magnetizable particles (10), the particles of granular material (5) form a compacted sorbing granular material (20) based on magnetic attracting forces between the magnetizable particles (10). The compaction is reversible. In addition, a process for producing a sorbing granular material (20) is provided.
