In the US and in Europe plasterboard waste disposed of in landfills have allegedly created the dangerous Hydrogen Sulfide Gas (H2S). Hydrogen sulfide is a colourless, flammable, poisonous gas that smells like rotten eggs. Hydrogen Sulfide gas is very dangerous and in high concentrations is lethal and in low concentration gives a rotten egg smell.
Potentially lethal hydrogen sulfite gasses (H2S) will develop in the landfill - Consequently gypsum waste should not be landfilled in the same landfill cell as organic/biodegradable waste; mono-cells for gypsum are required for safe landfilling. In addition leachate from gypsum waste will contain sulfur that could contaminate the ground water - Consequently gypsum waste should
