Acoustic Panels Made of Paper Sludge and Clay Composites

Studies on recycled materials emerged during recent years. This paper investigates samples’ sound absorption properties for panels fabricated of a mixture of paper sludge (PS) and clay mixture. PS was the core material. The sound absorption was measured. We also consider the influence of an air gap between panels and rigid backing. Different air gaps (50, 100, 150, 200 mm) simulate ...

Deinking - Wikipedia

The sludge is buried in a landfill, burned to create energy at the paper mill or used as a fertilizer by local farmers. Problems [ edit ] Water based flexographic printing inks with particle sizes below 5 µm and poor solubility in alkaline conditions may cause problems in deinking, especially in the flotation stage.
