Summary
Polluted water treatment and reuse has recently become a worldwide issue. Wastewater produced by residential units, companies, and industries contains human waste carrying a large number of bacteria and viruses as well as toxic and non-biodegradable complex organic compounds. The untreated wastewater may cause serious harm to natural water bodies, such as lakes, rivers, and seas. Harmful microorganisms and toxic compounds can cause outbreaks of epidemics and diseases such as: cholera, dysentery, or typhoid if they end up in drinking water. Therefore, developing an efficient technique to handle water and wastewater is essential. There are several effective approaches available to provide excellent results in terms of treated water quality, treatment time, energy usage, and sustainability requirements. Coagulation, flocculation, adsorption, photocatalysis, filtration, and membranes are examples of processes that can be used with operative materials. Numerous micro and nano-scale materials offer outstanding qualities, such as enhanced stability and large surface area for quick decontamination, as well as selectivity to remove diverse contaminants in an economical manner. This special issue outlines the main trends of organic/inorganic material development. In addition, it suggests hybrid materials as facile recycling materials. This special issue also includes original experimental and theoretical research on sustainable/renewable materials connected to key renewable and recyclable applications. Moreover, the recent applications of hybrid nanomaterials, polymers, composites, catalysts and biopolymers in various fields, such as water treatment, energy and hydrogen generation and semiconductors applications.
Potential topics include, but are not limited to:
· Advanced wastewater technologies.
· Sustainable water treatment.
· Nano polymers/materials.
· Renewable materials.
· Semiconductors.
· Solid waste management.
Keywords
Biodegradability, nanomaterials, polymers, hybrid composites, waste-based materials, inorganic materials.
