Natural rubber is a plant-derived material that continues to be widely used today, and it is one of the crucial materials to achieve the sustainable society. Nevertheless, it should be noted that not all natural rubber is produced through sustainable practices. There are several global issues that need to be resolved to achieve the sustainability of natural rubber. These issues include the risk of pathogen spread in para rubber tree (Hevea brasiliensis), the balance between rubber production and biodiversity, and the long-term sustainability of rubber farmers, for example.
This review paper introduces these issues with academic research finding. Furthermore, it presents current research on alternative rubber-producing plants such as russian dandelion (Taraxacum kok-saghyz) and guayule (Parthenium argentatum), as well as research on the biosynthesis of natural rubber.
