    If gypsum waste must be landfilled, it is controlled by specific Environment Agency rules. As a non-hazardous high-sulfate waste, there is a risk that large volumes of gypsum waste mixing with rainwater and organic waste materials could produce hydrogen sulphide, therefore it is not permitted in mixed waste but must be landfilled in dedicated, non-hazardous ‘high sulfate’ landfill cells
