Williams, Paul (1999, November 22). University Of Leeds. Retrieved January 30, 2007, from High Value Products from Scrap Tyres Web site: http://www.leeds.ac.uk/reporter/443/tyres.htm
This website discusses the tyre pyrolysis technologies being developed at the University of Leeds in the UK. The technologies and research lead to some interesting finds, such as the composition of tyre pyrolysis oil contains valuable chemicals such as “limonene”.
Williams, P.T., & Brindle, A.J. (2002). Catalytic pyrolysis of tyres: influence of catalyst temperature. Fuel. 81, 2425-2434.
This journal article describes research into the effect of the temperature of a zeolite catalyst on gas composition from tyre pyrolysis. The paper shows what gases are produced as a result of modifying the temperature. By using a catalyst they show a degree of control over the output gas, which has important commercial implications.
Yang, G. (1993). Recycling of discarded tires in Taiwan . Conservation And Recycling , 9(3), 191-199.
This looks at the 30 year old tire recycling program in Taiwan, with an emphasis on the 80s. It also discuses the government regulations and recycling methods (only found the abstract for this article).
