Why Is Plasterboard Banned From Landfill? As of April, 2009, plasterboard and a range of other items were banned from landfills.

Due to plasterboards gypsum content, it contains lots of sulphates, that when mixed with general waste and rubbish creates a chemical compound known as H2S, hydrogen sulphide. When this is allowed to happen and it gets wet, the plasterboard goes through the process of creating H2S which is called putrefaction.
How do you dispose of plasterboard waste?
