Recycling of Waste MDF by Steam Refining: Evaluation of Fiber and Paper Strength Properties

Abstract Currently, most of the collected waste medium-density fiberboards (MDF) is incinerated or landfilled, as economically viable recycling methods are yet to be developed. By steam refining (MDF), it possible hydrolyze incorporated resins and isolate a high yield fiber fraction. Further treated fibers might enable utilized in applications such paper packaging, facilitating cascading use material stream. To this end, intimate knowledge needed. In study, refined two MDF samples containing differing amounts softwood hardwood underwent beating. The resulting were characterized regarding their morphology test sheets produced evaluate strength (compression-, tensile- tear-strength). Distinct differences response between apparent. For sample with higher share an increase properties increasing treatment severities could observed was produce comparable compression recycled pulp for industrial corrugated paperboard. softwood, severity did not show any influence on properties, low comparison other sample.
