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.
