1st: the dandelions used to be useless. But one variety species called TKS, which produces molecules of rubber in its sap. The fruition of us and Germany could supplement the traditional rubber tree HB.
2nd: despite the invention of synthetic rubbers, it can't compensate the resilience and strength of natural rubber. Around 1/5 car tyre and 4/5 aero plane tyre made of natural rubble. Furthermore, the price of synthetic rubber tied to that of oil, and oil price will increase. Hence natural one looks like an attractive alternative.
3rd: in prevent of leaf blight, rubber tree planting needs wide space. Even in Asia, harvesting rubber plant means cutting down rainforests. Therefore, small plant that could be harvested for its rubber has advantages.
4th: Guayule, a shrub that is free from allergenic proteins, making it useful for items such as surgical gloves. Guayule takes two years to grow, while Hevea takes longer. H can yield **** , that's the place D can get in, because D is robust, can yield twice per year, so they could outstrip H.
5th: scientist in charge of producing usable rubber in TKS.
6th: coagulation is good things from the point of plant. But as human users, we do not want it to coagulate too soon, and DR SG used RNA interferece to make rubber extracting more easily
7th: meanwhile, MK uses traditional way to increase the yield of rubber from TKS.
8th: the combination of two methods may produce a rarity in the modern world. |
