If screws are used for mounting on the wall or in the ceiling the Panels and the Tiles can gently be removed and reused. If glued directly to the wall with recommended amount of glue used, the Small Tiles can possibly be removed and reused if removed with care. If the Panels & Tiles not can be reused for the project, they can be ground down and reused e.g. as ballast and filling material, moisture absorbent sprinkling, a substrate for running tracks etc.
