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 drywall biodegrade?
Sheetrock, also called drywall, is in the walls of almost any building constructed over the last few decades. It is made of gypsum, a soft rock, with thick paper on each side. Gypsum is natural, and will absorb water and break apart. The paper is biodegradable.

What happens to gypsum waste?
Gypsum waste disposal Gypsum was banned from normal landfill in 2009. If gypsum is mixed with other biodegradable waste in the normal landfill then hydrogen sulphide gas can be released. Hydrogen sulphide is a toxic colourless, flammable gas with a very distinct foul odour – rotten eggs.
Can gypsum board be used as fertilizer?
Gypsum wallboard is used to cover interior walls of homes, offices and other structures. Gypsum is used in agriculture as a fertilizer and as a soil amendment. Both calcium and sulfur are essential plant nutrients. Gypsum is not a liming material and will not increase soil pH.

What is a gypsum waste stream?
Gypsum waste primarily consists of waste from gypsum boards, which are wall or ceiling panels made of a gypsum core between paper lining. Such boards are also referred to as sheetrock, plasterboards, drywall, wallboards and gyprock. Gypsum waste from the manufacturing of gypsum products.

Most of the world’s gypsum is produced by surface-mining operations. In the United States, gypsum is mined in about 19 states. The states producing the most gypsum are Oklahoma, Iowa, Nevada, Texas, and California. Together, these states account for about two-thirds of the United States’ annual production of gypsum.
Why is plasterboard dangerous?
While it’s usually a harmless material, when placed with biodegradable waste it is known to create a toxic gas – hydrogen sulphide (H2S). It’s this gas which has made it tricky for people to dispose of the material safely since it is not only extremely odorous but it can be poisonous and flammable, too.
Is Gypsum bad for the environment?
Drywall production has a noticeable environmental impact. Processing the gypsum releases particulates from the gypsum powder in addition to sulfur dioxide, nitrous oxide, and carbon monoxide. An estimated 75% of drywall ends up in landfills, but efforts are increasing to promote recycling.
