ABSTRACT
A huge amount of waste is daily produced from kitchens worldwide which could be utilized to contribute to sustainable development. Kitchen waste mainly includes bioproducts of vegetables and fruits. This waste offers an opportunity to introduce innovative recycling systems for its management. The generation of nanoparticles from food waste is a reliable and economical solution to minimize food waste materials. The use of kitchen waste leftovers reduces the cost of nanoparticle fabrication and has many advantages over other synthetic resources which further emphasize the recycling of waste bioproducts. Nanoparticles generated from waste can be used for various applications such as antimicrobial, water purification, larvicidal and biomedical processes. The generation of nanoparticles through this waste is a sustainable green process that is environmentally friendly and relatively quick compared to other processes. The hazardous chemicals and reagents often used for the preparation of different kinds of nanoparticles are not environmentally friendly. That’s why the exploration of alternative sustainable approaches is needed. This chapter provides information on the utility of kitchen waste for the generation of silver and gold nanoparticles and their use in different applications. A note on the challenges and future prospects is also provided.
