Plasterboard
Plasterboard is defined as a "material consisting of two sheets of heavy paper with a layer of plaster between them, used to make walls and ceilings before putting on a top layer of plaster"[1].
The disposal of gypsum-based waste (i.e.plasterboard) to a landfill that accepts biodegradable waste is not permitted due to its potential to produce hydrogen sulphide gas during degradation[2].
