#0183;#32;The impacts of quarrying of the gypsum deposits on the environment at Maqna, Tabuk, were evaluated by intensive field studies including in situ testing, mapping and sampling of gypsum and well water. Field and laboratory tests were made to determine the engineering properties including tensile and compressive strengths, unit weight, fracture spacing and the rock quality designation (RQD) values.
Made from the simple materials of gypsum and paper it is used in most building types in a wide range of applications including wall lining, partitions, sound control and fire protection. The main environmental impacts associated with plasterboard result from the production process, transportation and disposal.
#0183;#32;Results show that there are no harmful impacts on the environment of the studied area associated with the extraction and quarrying of the gypsum deposits at the Maqna area. They also revealed that the gypsum can be quarried using a ripping technique, which does not create noise and/or vibration in the surrounding areas.
Chile: Germanys Knauf plans to invest US11m towards increasing the rate of gypsum extraction at a quarry its subsidiary Yesos Andinos operates at the Rub#237; deposit, in in San Jos#233; del Maipo, Cordillera Province. The company said in an Environmental Impact Study (EIA) that it wants to raise extraction to /yr, according to ValorFuturo. At present it is restricted to 35,000t/yr at the site.

Gypsum is considered to be one of the oldest construction material whose usage dates back to several thousand years ago. The growing negative environmental impacts of cement industry and high cost associated with the manufacture and transport of Portland cements have made gypsum an effective alternative to the hazardous cementitious products.

Gypsum is a soft sulphate mineral composed of calcium sulphate dihydrate. Gypsum has excellent fire resistance properties and it is cheaply available in the market. It is an excellent binder. Gypsum can be effectively utilised in the production of environmental friendly concrete.
Environmental. Recycled gypsum combined with raw gypsum produces a more desirable consistency for the manufacture of new gypsumbased products. NWGR has developed a number of innovations to ensure that the environmental impact of their recycling plants is minimal. Most notably, NWGR has developed an onsite wheel wash system that removes materials

#0183;#32;Finally, it is essential to point out that if the calcination phase were suppressed in the generation of recycled gypsum (powder), which is viable according to the tests carried out by Pedre#241;oRojas et al. (2019), the environmental impacts of this material would be substantially reduced, standing, on average, between 25 and 30% of those reached for natural gypsum.
Gypsum is a naturally occurring mineral composed of calcium sulphate and water (2CaSO 2 O). Gypsum can also be recovered as a biproduct of reducing the emission levels of coalfired power stations. Currently categorised as waste in the UK, FlueGas Desulpherisation (FGD), can be used as a construction material in its pure state.(*)
