Scylla Sp. Shell: a potential green adsorbent for wastewater treatment

Abstract

Crab (Scylla sp.) has long been recognized as an important commodity of coastal fisheries. Due to the high demand for fresh flesh in the food industry, an enormous amount of crab shell is generated as waste. Scylla sp. shell is a promising natural resource of green adsorbent for water pollutants. This commentary highlights the properties of Scylla sp. shell and the possible interactions with water pollutants. The superiority of crab shell adsorbents as compared to other novel adsorbents in previous findings was generalized and compared. The present challenges and future directions revolving around techno-economic perspectives were discussed to provide useful insight into practical applications in wastewater treatment.
