Japanese Patent JP5677566
Kind Code:
B2
Abstract:
Provided is a method of recycling waste scagliola, which includes a pre-treating step, a pyrolysing step, a resin recycling step, and a filler recycling step. The pre-treating step includes storing the waste scagliola of a dry dust type, drying and storing the waste scagliola of a wet dust type, or pulverizing and storing the waste scagliola of a scrap type. The pyrolysing step includes receiving and heating a recycling raw material stored in the dust or granular type in the pre-treating step, and decomposing the raw material into a resin mixed gas and a filler mixed solid material. The resin recycling step includes receiving the resin mixed gas decomposed in the pyrolysing step, and recycling a resin from which impurities are removed by a purifying process. The filler recycling step includes receiving the filler mixed solid material decomposed in the pyrolysing step, and recycling a filler from which impurities are removed by a firing process. Thereby, the resin and filler are more effectively recycled from the waste scagliola, so that it is possible to prevent environmental pollution caused by disposing the waste scagliola, and to enhance an effect of reducing resource waste according to resource recycling.
