In this regard, development of green catalytic processes are becoming attractive. Along this line, different chemical and enzymatic methods can be used for food waste valorization. Furthermore, cascade reactions such as chemo-enzymatic, multistep-chemocatalytic and multistep-enzymatic can also be tried for food waste valorization. These cascade reactions are particularly promising as the target products can be achived directly without isolation and purification of intermediates in a single solvent system
