Abstract
Wastes recovery efficiency bave been slightly improved by Decree n.248 of 29/7/2004 on" Rules on determination and disciplines of recovery activities of products and goods of asbestos and containing asbestos" by defining processes and treatment able to bring to a complete transformation of crystallochemical features of asbestos.Such treatments if properly applied allows to avoid thè disposai of wastes in dumps. They also allow thè reutilizalion of processed wastes. No adequate power plants suitable for thè mentioned treatment presently exist in Italy.Intense research activity is devoted to thè start up of pyrolitic processes applied to wastes deriving from concrete/asbestos to be reutilized in environmental recovery. Decree n.248 reports characteristics of processed material whìch must be asbestos free and accompanied by mineralogical composition of final produci.Present paper propose an analytical protocol suitable for law need and able to guarantee safety conditions of wastes after crystallochemical transformation.In order to verìfy such trans formations analytical procedures adopted in qualifìed laboratories on asbestos analysis nave been utilized. Pure chrysotile and concrete/asbestos samples have been analyzed by MOCF, DRX, SEM and FTIR after 2 hours heating at 600-700-800-900-1000 °C in muffle fornace. Some samples processed by pilot power plani by Aspireco have also been analyzed.
