resistance; this can equal up to one tank of fuel for every five tanks that cars use and one tank for every three tanks for trucks (Michelin Tires, n.d). First Stop: Almost every tire begins with natural rubber; rubber is obtained from the Para rubber tree (Hevea brasiliensis) trees grown in the ASEAN region of Thailand, Indonesia, Malaysia (Shuhaimi, Othman, Ismail, & Sasidharan, 2013). Mostly all rubber comes from these areas because the tropic Rainforest climate is conducive for growing rubber trees. The
The Rubber Tree (Hevea brasiliensis) Rubber is a valuable commodity in today's economy. A vast number of products are made from it, including washers, gloves, gaskets, tubing, waterproof clothing, toys, erasers, belts, elastics, bottle stoppers, and insulation for electrical wiring. The largest single use of rubber is in the manufacture of pneumatic tires which consumes 60% to 70% of the total world production each year. Demand for rubber has grown remarkably since the beginning of the industrial
the South American continent and it is shared by eight countries viz. Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname and Venezuela. Out of these, Brazil, Bolivia, Venezuela and Peru were the ONLY exporters of natural rubber before the Hevea plants were cultivated anywhere else in the world. For at least thirty years (1879–1912) Natural Rubber is known to have underpinned one of the most important development booms in these countries particularly Brazil. This so called Amazon Rubber boom
Synthetic and Natural Rubber Abstract Rubber is an important resource with a wide variety of applications. It can be obtained naturally from the rubber tree, Hevea brasiliensis. It can also be synthesized from petroleum and natural gas. Both natural and synthetic rubbers have their own advantages and disadvantages. Natural rubber is made up the linear chain polymer, cis-l,4-polyisoprene. Styrene-butadiene rubber (SBR) is the most common synthetic rubber. It is a random copolymer of styrene

the farmers. Hence an economic treatment method needs to be adopted to ensure pollution control at the farms along with benefits of their investment. 1.2. RUBBER INDUSTRY: Natural Rubber latex is a milky white liquid obtained from the rubber tree (Hevea brasiliensis) The rubber tree grows in tropical climates with moderate rainfall and has an economic lifespan of about 25 years [1]. It starts yielding latex after it is around 7 years old and each tree produces about 600ml of latex per tapping. Tapping
