gypsum and post-consumer gypsum material) and gypsum paper for facing. When combined the noted inputs produce a main product. The rules applied to determine the allocation of environmental impacts are: Quarry production system – On mass basis, quarry production produces 97% of quarried gypsum (main product) and 3% of solid rock (co-product).

Gypsum is a soft, abundant mineral mined around the world. It is typically mined by blasting mineral deposits in a quarry. 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. Heating the gypsum also has

Reuse and recycling can also reduce the environmental effects of coal production and use. Land that was previously used for coal mining can be reclaimed and used for airports, landfills, and golf courses. Waste products captured by scrubbers can be used to produce products such as cement and synthetic gypsum for wallboard.
Calcium Sulphate Dihydrate (Gypsum) is commonly hydrated by groundwater. The UK is largely self-sufficient in gypsum. The material can be found in seams in the Pennines and the Midlands, but the biggest source of extraction is in East Sussex where mining extracts some 100,000 tonnes of gypsum a year from 100 m below the High Weald.
The greater the use of FGD gypsum, the smaller the need for mined gypsum and the lower the environmental impact – meaning a maintained profit for gypsum factories. Recycling. Gypsum is often referred to as 'eternally recyclable', and due to pressure in the industry there has been a drastic increase in the recycling of gypsum.
Especially against the background of a circular economy, the recycling of waste gypsum is of growing importance. However, the use of recycled gypsum only makes sense if it is environmentally friendly. Therefore, an evaluation of the environmental impacts of industrial-scale processing for the recycling of post-consumer gypsum waste was conducted.
