| Research Abstract |
We investigated decomposition of composites containing asbestos by melting using laser irradiation. Many laser sources were compared and continuous and pulsed irradiation were tested, and we discovered that pulsed irradiation from a low-cost CO_2 laser can be used for processing. Various processing conditions were investigated with a small laser system with 50W output. We found a condition that allows a small laser system to process 5mm-thick asbestos, which is close to 6mm, the thickness of a slate. Observation by SEM of the processed region confirmed removal of asbestos.
