Waste is an unwanted byproduct of human actions that physically contains the same substance as the valuable product. Waste is produced as a result of inefficient manufacturing processes, and its constant creation results in a waste of critical resources. Recycling is the conversion of waste materials into new materials and things, and a material's recyclability is determined by its ability to regain the attributes it had in its virgin or original state. Waste is divided into broad categories depending on its environmental impact (hazardous and non-hazardous waste), physical state (solid, liquid, and gaseous waste), and source. Biological reprocessing, energy recovery, and physical reprocessing are some of the waste recycling processes available. The purpose of waste management is to create sanitary living circumstances in order to limit the quantity of garbage that enters and leaves society while also encouraging the reuse of waste. Fermentation of organic waste, anaerobic digestion, bioleaching, biosorption, and bioreduction are examples of biochemical waste recycling technologies. We review to provide adequate and concise information on the biochemistry of waste management.
