gypsum production from coal plant

FGD Gypsum Introduction

This website pertains only to FGD gypsum, produced by coal-fueled power plants. There are many uses for FGD gypsum, including agriculture, gypsum panel products, highway construction, mining applications, cement production, water treatment and glass making. This website describes how FGD gypsum is produced, handled and used in a variety of ways.

Gypsum as an agricultural product Soil Science Society

Gypsum that comes from coal plants is called flue-gas desulfurization gypsum, as it comes from the process that ‘scrubs’ sulfur out of the smoke stacks to reduce air pollution. “The gypsum that is recovered has good quality,” says Dick. “The gypsum particles are small and uniform in size making them quite reactive.

Synthetic Gypsum BuildingGreen

Jul 30, 2010· Synthetic gypsum, which is now used in about 30% of drywall, is a byproduct of coal-fired power plants. It is sometimes confused with fly ash—another coal combustion product that’s been in the news recently—but the two have very little in common. Synthetic gypsum is also called flue-gas-desulfurization (FGD) gypsum.
