208 Life Cycle Assessment of Wastewater Treatment

capture phosphorus from waste water with the aim of waste minimization and eco-
nomic value. Batch adsorption studies were performed in comparison with other sor-
bents, which proved that land snail shell was a promising adsorbent for phosphorus
removal and recovery as fertilizer (Oladoja et al., 2017). With similar perspectives,
many more plant materials, weeds, and agricultural wastes have been exploited for
their removal capacity for the elimination of phosphorus. Table 10.2 lists different
biosorbents used for the removal of phosphorus.
