AEROBIC DEGRADATION OF MEDIUM DENSITY FIBERBOARD (MDF) AS A WOODMANUFACTURING INDUSTRY WASTE WITH COMPOST ADDITION
Published: 2 Jun 2014
Abstract: The fiberboard waste constitutes in our days an important part of urban waste stream, because they are used in increasing amounts, for the production of interior wood constructions. The management of such waste already troubles the modern societies. However, via biodegradation it is possible this waste material to constitute a valuable resource for the production of new wood based panels, thus helping on one part in the partial satisfaction of increased needs for wood and on the other part in the restriction of problems caused by these materials when they are disposed. The aim of this researchwas to study the influence of compost in degrading formaldehyde adhesives so that a large percentage could be reused as wood waste panels or further environmental disposal. Particularly we managed to determine whether the contact of these two materials favors the degradation of formaldehyde adhesives. It was used small chamber test in stable conditions (temperature, moisture, weight) for 21 days period, using wood waste from the same fiberboard in order to reduce heterogeneity problems. Further removal of formaldehyde, confirms that compost could be a favorable factor in wood waste degradation. Nevertheless, it is particularly important the way that compost participates in process.
