Question

Which toxic gas is released when plasterboard is broken down in landfill condition?

Answer 1

Gypsum board is a layer of calcium sulfate dihydrate (gypsum), usually pressed between the top and bottom layers. It is used to make interior walls and ceilings. This "gypsum board" structure is popular as a quick alternative to traditional slats and plaster of paris. Gypsum board is used to help builders and designers comply with building codes for fire safety, sound insulation, and thermal efficiency. It can also help control condensation and possible damage in high humidity areas.

Complete answer:
During the process of manufacture and after the use of plasterboard, there is a lot of accumulated waste that goes into the landfills. The breakdown of the plasterboard generates a lot of pollutants.
When building rubble is processed, it can be dumped. Various microorganisms act on the waste beneath the surface or, under anaerobic conditions, various components of the waste are broken down. Certain components of construction rubble, such as plasterboard, are dangerous after landfill. When plasterboard decomposes in landfill conditions, hydrogen sulfide gas is released. This gas is very poisonous. If inhaled, ingested, or in contact with the skin, it can cause health problems and even death.

Note:
The use of plasterboard as a drywall coating indoors is a relatively new application. It has become a popular method of replacing gypsum plaster because it is cleaner than wet plaster, requires less labor, and reduces the drying time of building structures. By embedding accelerated semi-aqueous slurry between the paper linings and the subsequent oven-dried production, the strength of plasterboard lies in the heavy paper facing.
