Life Cycle Assessment of Waste Source‐Derived Chemicals as Adsorbents

Life cycle assessment (LCA) of the current environmental scenario can be evaluated in terms of cradle‐cradle. The basic understanding of cradle‐cradle refers to the different phases of analysis, recovery, reusability, sustainability, and circular economy of any prospective work. Currently, wastewater treatment is one of the most widely researched topics across the globe due to its adverse environmental impacts. A detailed study on the environmental impacts of adequate utilization of waste‐derived adsorbents in the wastewater treatment processes is also analyzed through LCA studies that are defined by ISO‐14000, which is a comprehensive set of standards for environmental management. The selection of a proper adsorbent for wastewater treatment studies is one of the major aspects to be concentrated on. Hence, the adsorbents derived from various waste materials will aid in the development of low‐cost pilot scales of wastewater treatment and also lead to the enhancement of a circular economy that maintains a proper life cycle assessment of these novel chemicals. It is also mentioned that the replacement of these conventional adsorbents with various other non‐conventional adsorbents will aid in maintaining a clean and green sustainable environment in terms of circular economy concepts, reduce, recycle, and reuse. From these studies, it is concluded that a gradual reduction in the continuous rise of energy demand and the development of a clean and sustainable environment can be maintained.
