China needs more and more rubber resources to support its rapid development of economy since it became the world's second largest economy in 2010. Rubber materials could be obtained from two sources : one is natural rubber which comes from Hevea brasiliensis

but it is shortage in China; the other is synthetic rubber which is unsustainable because of its dependence on fossil resources. Therefore

using solar energy to develop biorubber is the future of sustainable development of China rubber industry. Biorubber can be divided into two categories : one is the bio-based engineering elastomer(BEE) which was synthesized from new bio-based monomers such as itaconic acid fermented from annually renewable agricultural and biomass feedstock

or synthesized from traditional bio-based monomers ( for example

isobutylene etc.) transformed from fermentative monomers (for example

isobutyl alcohol etc.) ; the other one is natural rubber including para rubber and the second natural rubber(SNR)

such as TKS rubber

guayule and Eu-gum. The review shows research progress in BEE and SNR

but the para rubber is not reviewed here any more because of its long research history and lots of literatures.
