Natural rubber is produced from plants and is classified as a polymerA chemical compound with large molecules made of many smaller molecules of the same kind. Most natural rubber comes from rubber trees in Southeast Asia, but this source is now under threat from a fungus. Inulin is an interesting by-product of Tks (Van Beilen and Poirier, 2007a). Nearly all this rubber currently has its origins in rubber tree plantations in Asia. Rubber Root, alternately known as Russian or Kazakh Dandelion (Taraxacum kok-saghyz) is a perennial dandelion with origins in the Kazakhstan / Uzbekistan regions.The plants are smaller than Taraxacum officinale and Taraxacum albidum (two other varieties we offer in our catalog), with thicker and a paler greens. In the course of a systematic investigation instituted in Russia in 1929 to determine the possibilities of producing natural rubber in that country, the kok-saghyz was found near Tien Shan, Kazakstan, near the border of China. Natural rubber is an indispensible ingredient in tens of thousands of applications, from car and aircraft tyres to medical equipment. Russian dandelion rubber is chemically suited for use in tires and as latex for gloves, making it an ideal replacement for rubber tree products, says Wolyn. A previous project, EU-PEARLS, showed that the Russian dandelion, or Taraxacum koksaghyz, is a viable option. Rising oil-prices limit the economic viability of synthetic rubbers, and synthetic equivalents often cannot pragmatically replace natural rubber. DRIVE4EU is now focused on the development of a successful production chain in Europe. Inulin is an interesting by-product of Tks (Van Beilen and Poirier, 2007a). Now, environmental and economic factors are reviving interest in this alternative raw material. Nearly all this rubber currently has its origins in rubber tree plantations in Asia.

This is the Russian dandelion, or Taraxacum kok-saghyz. Attention on T. kok-saghyz has revived due to allergic reactions to Hevea rubber used in medical devices, and to shortcomings in the supply of rubber from Hevea brasiliensis. Natural rubber is a valuable commodity because it has useful properties that synthetic rubber lacks. OSU's research on making rubber from the Russian dandelion was a continuation of work done by a Russian university, Milewski said. In the course of a systematic investigation instituted in Russia in 1929 to determine the possibilities of producing natural rubber in that country, the kok-saghyz was found near Tien Shan, Kazakstan, near the border of China. To date several European tire manufacturers produced durable tires from dandelion rubber as proof of this concept (e.g. Also known as Kazakh dandelion or rubber root, Russian dandelion resembles the familiar dandelion, but the leaves are thicker and have a grayish tint. In the 1930’s, Russia produced ~30% of their domestic rubber from 67,000 hectares of this plant. TKS can be [W Gordon Whaley; John Stevenson Bowen] -- This publication is a summary of the investigations conducted between early summer 1942 and June 1944, when the attempt at large scale experimental production of kok-saghyz was terminated. Russian dandelion is a close relative of our native dandelion. Continental isn’t using just any old dandelion but a specific Russian species. Another rare dandelion that we’ve taken under our wing. [3] T. kok-saghyz was discovered in Kazakhstan in 1932 by the Soviet Union in an effort to find a domestic source of rubber. With the conclusion of World War II and the return of affordable Hevea brasiliensis rubber (which has 8 to 10 times the yield[8]), the majority of T. kok-saghyz programs ceased. Brandon S. Gaut Department of Ecology and Evolutionary Biology,University of California, USA Reviewer of NSR ... One such plant is the Russian dandelion, Taraxacum kok-saghyz (or TKS). Currently, NovaBioRubber grows Russian dandelion in British Columbia, Canada. Get this from a library! Unlike other rubber-bearing plants, this dandelion species also contains inulin, a food additive … The roots of this dandelion species contain the natural rubber latex (the source for natural rubber used in tires), meaning supply will be steadier and easier to control leading to greater price stability. The Russian dandelion (Taraxacum kok-saghyz, TKS), which has lately been called the rubber dandelion, has been studied as a major alternative crop since World War II, because it can produce natural rubber of good quality [1,4].

The dandelion rubber used is cultivated, extracted and processed in Germany. A previous project, EU-PEARLS, showed that the Russian dandelion, or Taraxacum koksaghyz, is a viable option. Trees on rubber plantations in south east Asia take years to grow to maturity. Since dandelions are only of limited use as a wild plant for agricultural production, plant breeders clarify the physiology of rubber synthesis and develop suitable varieties for successful industrialization. Michel said, “The pilot plant has been used to process nearly a ton of Russian dandelion roots to produce kilogram quantities of rubber … The draft TKS genome assembly has a length of 1.29 Gb, containing 46 731 … [5], Taraxacum kok-saghyz is a perennial plant with a yellow composite flower characteristic of the genus Taraxacum. Russian Dandelion and Guayule have almost identical qualities compared to natural rubber harvested from the Hevea tree, which is currently the primary source for the natural rubber used in tires. Aside from the rubber extraction from the root, the isolation and commercial exploitation of inulin can also be taken into account. [4][2] In May 2019 German tire-maker Continental AG announced it was about to begin production of the "first bicycle tyre made with sustainable rubber from dandelions", which it intended to grow on the grounds of its own manufacturing plants, avoiding several of the traditional issues with H. brasiliensis latex—from the long lead-time between planting and cultivating (only six months for the dandelion, rather than seven years for the rubber tree) and volatile prices of the product due to the long transport-distances between places where the rubber can be grown and the company's factories. kok-saghyz. Since dandelions are only of limited use as a wild plant for agricultural production, plant breeders clarify the physiology of rubber synthesis and develop suitable varieties for successful industrialization. [2][4], Kok-saghyz is derived from the Kazakh kök-sağız (көк-сағыз), with kök meaning green and saghyz meaning rubber or gum. 217-231. The Russian dandelion, Taraxacum kok-saghyz (TKS), is a perennial species native to Central Asia that produces high quality, natural rubber. Advanced embedding details, examples, and help! Because of the invention of synthetic rubber and the higher yields of rubber per hectare from the rubber tree, the dandelion was mostly forgotten. In the 1930s, Russia experimented with making rubber from dandelion roots but abandoned the project after the war. [9], Researchers have started to develop Taraxacum kok-saghyz cultivars which are easier to cultivate and which produce more and better rubber as part of a large research project at many institutions. It enriches in its roots a whitish, sticky, rubbery milky sap, the so-called latex. It also grows in temperate climates and is thus able to expand natural rubber production to our regions. The Urban Taraxagum bicycle tire, available on the market since 2019, is the first serial product made of dandelion rubber that combines local production with minimal transport distances in … Here we present the draft genome of TKS, the first assembled NR-producing weed plant. These should be characterized by high root yields, latex content and resistance to plant diseases, pests and drought. Flowers are hermaphroditic. Abstract. Although natural rubber is found in at least 2,500 plant varieties, most of these are unsuitable for the large-scale production of good quality rubber. The Russian dandelion Taraxacum kok-saghyz Rodin (TKS), a member of the Composite family and a potential alternative source of natural rubber (NR) and inulin, is an ideal model system for studying rubber biosynthesis. Now, dandelion rubber proponents say long-term concerns about prices , sustainability and labor availability are strong enough to develop dandelion rubber seriously. “We are making […] crosses between the Russian dandelion and the common dandelion using those modern DNA profiling technologies,” says KeyGene CEO Arjen Van Tunen. This is the only dandelion that can be used as an alternative source for natural rubber production. It enriches in its roots a whitish, sticky, rubbery milky sap, the so-called latex.
