Abstract:

The tests presented describe a method of pressureless agglomeration of waste shavings derived from chrome tanning processes with the addition of gypsum obtained from the Bełchatów Power Plant, from the filtering of sulphur compounds from exhaust gas and widely available dolomite. The aim of the granulation process is to minimise the environmental impact of the storage and transport of tanning shavings. The method proposed of rendering this waste harmless through its granulation on a disk apparatus using a soluble glass solutionto moisten the deposit is simple and its cost remains economically reasonable. As a result of the completed tests, a loose, agglomerated particulate deposit was produced containing both mineral and organic components, and which can also be easily stored, transported and dosed in other process operations. Agglomerates produced using the method devised in theinvention may be used in place of the loose, wet, dusty shavings for manufacturing composite materials based on fragmented collagen fibres.
