Progress in resources recovery from solid wastes for water treatment

This review explores the vast potential of resource recovery from various classes of solid wastes, including food, industrial, and plastic wastes, with a focus on their applications in corrosion inhibition, nanoparticle synthesis, and sustainable energy production. The study highlights the growing need for innovative and eco-friendly solutions to waste management challenges and the shift toward a circular economy. Conducted as a comprehensive review, the work synthesizes information from recent studies and technological advancements to address existing knowledge gaps, particularly concerning the industrial scalability and environmental benefits of resource recovery processes. The review emphasizes the transformative role of food waste-derived corrosion inhibitors, such as those from Carica papaya and orange peel extracts, in protecting metals and alloys. Similarly, plastic wastes have demonstrated promising applications as coating materials and solvent-free corrosion inhibitors. Moreover, the synthesis of nanoparticles from solid wastes, including periwinkle shells and rice husks, has shown significant potential in environmental remediation, catalysis, and water purification. Despite the progress made, knowledge gaps persist in optimizing production techniques and scaling up recovery processes for industrial applications. This review underscores the need for further research and development to harness the full potential of solid waste as a valuable resource. 

Recommendations include implementing effective waste management policies, increasing public awareness, and expanding research to enhance efficiency and scalability. This review contributes to the growing body of knowledge aimed at achieving sustainable development through innovative waste recovery strategies.
