Abstract
【解決手段】 ケーシング2内部にアスベスト含有建材破砕用の破砕手段3を備えると共に、前記ケーシング2内部には少なくとも破砕手段3が浸かるように助燃性の液体であるグリセリンGを貯留しておく。そして、このケーシング2内部にアスベスト含有建材Aを供給し、グリセリンG中に浸漬させながら破砕手段3にてアスベスト含有建材Aを破砕処理した後、グリセリンG中に沈降したアスベスト含有建材の破砕片A´をキルン等で加熱溶融処理することにより、破砕処理時におけるアスベストの大気中への飛散を確実に防止できると共に、溶融処理時においては破砕片A´に付着、或いは浸み込んでいるグリセリンGが助燃効果を発揮して、効率よく良好に処理することが可能となる。
