Latest Market Trends

Plasterboard Recycling to Recover Calcium Sulfate

Plasterboards are manufactured from calcium sulfate dihydrate. These plasterboards are widely utilized in the construction industry for interior walls, ceilings. After usage, the waste plasterboards adversely impact the environment. Companies such as Gyprock and Regyp from Australia recycle all types of plasterboards into products beneficial for key industries such as agriculture. This recycling of products offers resource conservation, landfill reduction, and economic benefits. The increasing demand for plasterboards and associated waste propels the need for recycling to recover calcium sulfate and utilize it in the manufacturing of other products.

Introduction of Solution Grade Calcium Sulfate

Calcium sulfate is not a highly water-soluble chemical. The low solubility of calcium sulfate imposes challenges in the agriculture industry, where the nutrients that reach plants can be delayed. Hence, to transform the delivery of nutrients, manufacturing companies developed solution-grade calcium sulfate that delivers plant nutrients in a faster manner. Custom Hydro developed Valu-Fil 650, a high-purity, finely ground calcium sulfate dihydrate, mainly utilized to improve soils in turfgrass and agricultural applications. Valu-Fil 650, through an irrigation system, quickly and efficiently supplies the calcium needed to maintain the soil’s salinity. Development of such products propels the demand for calcium sulfate in the agricultural industry.
