Expanded Styrene is an inexpensive, readily available polymer used in packaging foams. With this, foams created on polystyrene cause environmental problems because they are non-degradable and have little recycling. Therefore, foams with energy sources are necessary for degradable production packaging and to deal with plastic issues. This review emphasizes different strategies of starch-based manufacturing, modification of starch-based foams to improve mechanical  properties and durability concerning humidity, biodegradable foams based on cellulose in anno to improve mechanical and thermal properties and related challenges in the development of bioplastic aimed at using them as alternatives to polystyrene in packaging. Starch source, process conditions, type of fiber and addition of other polymers, compatibility between composite components affect foam porosity, mechanical properties and morphology. In addition, these materials have positive environmental benefits and are desirable to be recycled. If these materials are to be increasingly sustainable and the challenges in their production and application due to the reduction of the effects of auxiliary plastic materials, performance characteristics such as durability, strength and low price can be considered for the use of these products. Therefore, study and investigation in the field of foams based on degradable biological materials with suitable properties.
