The presence of an increasing number organic pollutants in water now poses serious risks to both human health and ecological systems. Many these are persistent non-biodegradable. contamination fresh by harmful substances has compelled researchers develop innovative, efficient, cost-effective remediation techniques materials. Thus, photocatalysis long been recognized as a promising approach tackle environmental the energy crisis. However, semiconductor photocatalysts frequently suffer from defects such photo-generated charge carrier recombination, poor visible light response, slow surface reaction kinetics, which can be remedied modifications with appropriate co-catalysts. Therefore, graphene its derivatives have widely used supports for semiconductors due their distinctive optical, physicochemical, electrical features. This critical review addresses current progress design synthesis graphene/semiconductor photocatalysts, well use photocatalytic degradation hydrogen production. Several influencing parameters addressed, including pH, photocatalyst loading, initial pollutant concentration, wavelength, oxidizing species, all could significant impact on rate pollutant's degradation. Furthermore, recyclability catalyst activity mechanisms thoroughly discussed. Numerous case studies systematically presented. Moreover, future prospects major challenges highlighted.

It is urgent that we increase global food production to support population growth. Food requires significant resources, amongst them water and energy. Therefore, any losses of or other agricultural products also means a waste energy resources. A amount these occurs during the postharvest stage, primarily processing storage. This considered avoidable waste. The water-energy-waste nexus (WEW), its relationship production, needs be investigated from circular bioeconomy lens. Furthermore, alternative uses wastes should investigated. review focuses on agro-wastes their management as sources for bioactive compounds, biofertilizers, biomaterials, nanomaterials, pharmaceuticals medicinal agents, growth media, e.g., plant tissue culture. We potential contribution bioenergy (bioethanol, biogas, biofuel).
