Abstract
Since recently recycling of particle- and fibreboards is gaining momentum in Germany due to stringent regulations. Recycling methods based on steam hydrolysis of particle- and fibreboards seem to evoke industrial interest. Therefore, in this work the influence of steam hydrolysis of UF-bonded particle- and medium density fibreboards (MDF) on the degradation of UF-resins therein and on the pH-value of extractives obtained by hydrolysis of boards have been investegated. Moreover, the influence of steam hydrolysis on yield and pentosan content of the lignocellulosic material was also assessed.
