I invite you to go through my article "Role of Gypsum Wastes in Polluting Groundwater and Enhancing Eutrophication in Coasts of Aqaba" on my site on researchgate and suggest uses for gypsum wastes, produced as by-product by fertilizers manufacturing.
In Bolivia (my country) gypsum wastes are used to manufacture pre-fabricated walls of plaster for the construction of low-budget houses.
We have a lot of gypsum waste from the process of removing sulfuric acid smoke from coal power plants in Denmark. Much of it is used for pre-fabricated walls plates. They are very popular and gives good fire prevention.
Gypsum is used as a component in cement mixtures as an agent to control the setting rate of the cement.
In Brazil we use it as a soil profile conditioner. Due to its formula (CaSO4), specifically due to its anion, gypsum is not able to increase soil pH. However, SO4-- can form neutral ionic pairs with Ca, Mg and K, carrying them down the soil profile. It improves soil fertility in deeper soil layers and also decreases Al+++ toxicity. It helps increasing the soil zone explored by roots, which increases plants productivity and tolerance to droughts. It is also a source of Ca when soils have low Ca content but high pH.
We can use it in JORDAN as a treatment for sodic soil reclamation
It can be used for manufacture of pre-fabricated walls of plaster for construction of low-budget houses.
