The rapid depletion of fossil resources and rising environmental concerns are recent challenges facing the polymer industry which relies on petroleum. Therefore, seeking an unconventional solution to these problems is crucial. The synthesis of polymers from renewable resources has become a serious solicitude of researchers. The utilization of green polymers provides a suitable solution for fossil fuel consumption and the consequent rising environmental menace.

Polyesters, one of the foremost versatile polymers, have been widely used in fibers, plasticizers, plastics, and coatings. The majority of these materials are produced from petrochemical resources. However, many researchers are specializing in developing and industrializing polyesters derived from bio-based monomers. Moreover, bio-based polyesters are closely related to monomers from renewable resources. However, these monomers are favorable for synthesizing polyesters with new structures and characteristics. This review deals with different synthetic approaches for bio-based monomers to polyester and its application in environmentally friendly packaging materials.
