Abstract
Residual sludge coming from dimension stones working plants represents a problem for European Stone Industries. The difficulties to opportunely exploit such waste are related to their chemical and physical characteristics. Moreover the management of sludge is subject to periodic updating regulatory developments (DLgs 152/06, DLgs 13/09 and DLgs 61/2012 in Italian legislation) which can complicate their correct management. The topic of the research, financed by Camera di Commercio VCO (Verbano Cusio Ossola—Piedmont Region—NW Italy), is the evaluation of the best methodologies for residual sludge treatment and exploitation. A chemical and physical characterisation on the sludge as such, and on several mixes produced to individuate the more suitable recycled products, was foreseen. Laboratory and in situ tests are in progress (2012–2014). The paper aims to demonstrate that, on the basis of a strict characterisation, appropriate treatment and correct management it is possible to turn residual sludge (waste) into resources (potentially alternative to the natural ones).
