Phosphogypsum Management Perspectives. Massive Valorization or Massive Storage?

Phosphogypsum (PG) management is a challenge to the authorities worldwide especially because of environmental concerns. PG valorization has been essential as its storage has reached critical quantities. Several studies were carried out in this context to focus on the possibilities of PG valorization especially in agriculture and civil engineering fields as massive valorization axis. However, PG valorization is still quite limited which makes of its storage into embankments a temporary alternative to manage it. Although, PG deposit into embankments is ground intensive and limited by the critical areas and height they can reach. The study of new alternatives is progressing to help optimizing storage areas till putting PG valorization in action.
