Phosphogypsum (PG), a byproduct of phosphoric acid production, is termed as waste that can be utilized as an efficient alternative in various industrial applications. Although millions of tons of PG waste are generated yearly, only a small proportion of it is repurposed for industrial use in other applications. A huge amount is being dumped into the environment, which causes serious ecological problems in soil, air, and water. A significant and comprehensive evaluation of sustainable PG valorization approaches among various industrial applications is critical for developing novel strategies. Therefore, there is a need to establish or incorporate sustainable valorization strategies of PG for industrial implementations with enhanced chemical properties. This study aims to provide a sustainable approach to utilizing PG waste through subsequent washing, followed by integration with ammonium carbonate that yields ammonium sulfate and calcium carbonate. These products were efficiently evaluated by characterization methods and validated as efficient valorization of PG, where one is used as a fertilizer, while the other is used as a construction material. Therefore, this study provides valuable insights into utilizing Moroccan PG waste as an effective byproduct due to its significant recovery potential, providing a new way of valorizing PG in agriculture and construction materials.
