Plasterboard is made from an inner layer of gypsum sandwiched between two outer layers of lining paper. This is because when gypsum is disposed of alongside biodegradable wastes it can lead to the production of odorous and toxic hydrogen sulphide gas.
Is gypsum a hazardous waste?
Gypsum, the main raw material for plasterboard, is a sulphate but is classified as non-hazardous. Under the new regulations, waste containing gypsum can no longer be mixed with biodegradable waste at a standard landfill site.
Why is gypsum banned from landfill?
The landfilling of gypsum and other wastes with a high sulphate content together with biodegradable waste has been banned in England and Wales since July 2005. This is to prevent the build up of hydrogen sulphide gas which is both toxic and odorous.

Does gypsum biodegrade?
Under oxygen-depleted conditions, such as in a landfill or several feet underground in a covered hole, the gypsum (calcium sulfate) in drywall can decompose to release the noxious gas hydrogen sulfide.
Why is plasterboard banned from landfill?
Why Is Plasterboard Banned From Landfill? As of April, 2009, plasterboard and a range of other items were banned from landfills. The principal reason behind this move was that, when land-filled with other mixed waste residues, putrefaction occurs. The end result of this is that Hydrogen Sulphide is produced.
Where would you go for advice on disposal of gypsum waste?
Therefore, regulations state that “non-hazardous gypsum-based and other high sulphate bearing materials should be disposed of only in landfills for non-hazardous waste in cells where no biodegradable waste is accepted.” However, it is not necessary for any such materials to go to landfill at all.
What is the biggest problem in waste management?
Indiscriminate burning of waste can cause major air pollution and increases greenhouse emissions. As well as the immediate affect on the local air quality, often accompanied by an increase in respiratory diseases, it also contributes to global warming.

What is gypsum waste NHS?
Gypsum-rich wastes include plaster dental study moulds which, when landfilled with other waste (including residues from clinical waste disposal), can produce hydrogen sulphide gas from microbial action. Gypsum is generally inert, but it is also highly absorbent.
