Abstract: An elongated planar or profiled component for a manufacturing machine of a fibrous cellulosic web, such as paper, board or tissue web, is at least partially formed from a composite material having a continuous polymer matrix, and reinforcing inorganic fibers embedded in the continuous polymer matrix. The continuous polymer matrix is biodegradable and the reinforcing inorganic fibers are biodegradable glass fibers. A method is disclosed for recycling elongated planar and/or profiled components used for manufacture of a fibrous web.
