What is plasterboard used for?
Plasterboard is used primarily in the construction industry to build interior walls and ceilings. It is estimated that 15% of all plasterboard on new build sites is offcut wastage.
Is Plasterboard hazardous?
Plasterboard is non-hazardous in normal use and whilst it decomposes in landfill, in doing so it releases hydrogen sulfide, a chalcogen hydride gas, which is highly flammable, poisonous, and corrosive.
Bacteria is also formed, which converts the paper in the board to methane gas, which is non-toxic, but very flammable and can be explosive when mixed with air.
How is it safely recycled?
Plasterboard is recycled at a specialist plant which processes the gypsum so that contaminants are stripped out and the paper content mechanically removed. Virtually all impurities are removed during the process.
What are the benefits of recycling plasterboard?
Recycling plasterboard reduces the need for the quarrying and production of gypsum. Which saves energy and depletion of natural resources. 94% of the waste can be used to make new plasterboard. Alternatively, it can be used as a component in cement, or in agriculture. The recovered paper content is also recycled for reuse.
