Owing to various advantages of artificial marble compared to natural marble, its application has been rising exponentially, which has resulted in the generation of a significant amount of waste artificial marble through various processes. This study focuses on the recovery of methyl methacrylate from the waste artificial marble powder through pyrolysis reaction. The pyrolysis experiment was conducted in a horizontal tubular furnace at various pyrolysis temperatures (300–500 °C) at an interval of 50 °C. The liquid product was obtained through condensation. Liquid and solid product characteristics were studied. Significant cracking of the liquid product was obtained for 450 and 500 °C. From the solid phase analysis, it was observed that aluminum oxide (Al₂O₃) was obtained through the calcination of waste artificial marble powder at 800 °C.

由于人造大理石与天然大理石相比具有多种优势，其应用呈指数增长，这导致通过各种工艺产生了大量的废人造大理石。这项研究的重点是通过热解反应从废弃的人造大理石粉末中回收甲基丙烯酸甲酯。热解实验是在卧式管式炉中以50°C的间隔在各种热解温度（300–500°C）下进行的。通过冷凝获得液体产物。研究了液体和固体产品的特性。在450和500°C下获得了明显的液体产物开裂。从固相分析中观察到氧化铝（Al ₂ O ₃）是通过在800°C下煅烧人造大理石废粉而获得的。
