Recycling can be carried out on various raw materials. Recycling is an important part of creating more sustainable economies , reducing the cost and environmental impact of raw materials. Not all materials are easily recycled, and processing recyclable into the correct waste stream requires considerable energy.
It is mainly composed of gypsum (CaSO 4 ·2H 2 O). Although gypsum is a widely used material in the construction industry , phosphogypsum is usually not used, but is stored indefinitely because of its weak radioactivity caused by the presence of naturally occurring uranium (U) and thorium (Th), and their daughter isotopes radium (Ra), radon (Rn ...
