Title:
METHOD FOR PROCESSING WASTE SCAGLIOLA
Document Type and Number:
WIPO Patent Application WO/2011/145774
Kind Code:
A1
Abstract:
According to the present invention, a method for processing waste scagliola comprises: a preprocessing step; a thermal decomposition processing step; a resin recovery step; and a filler recovery step. In the preprocessing step, waste scagliola in a dried particle state is stored, waste scagliola in a wet particle state is dried and stored, or waste scagliola in scrap form is crushed into particles and stored. In the thermal decomposition processing step, the recycling material stored in particle or granulate form in the preprocessing step is fed to be thermally treated and is decomposed into a resin-containing gas and a filler-containing solid. In the resin recovery step, the resin-containing gas decomposed in the thermal decomposition processing step is fed to be removed of impurities in a purification step in order to recover resin. In the filler recovery step, the filler-containing solid decomposed in the thermal decomposition processing step is fed to be removed of impurities in a calcination step in order to recover filler.
