1 Vol with 256 communicatons to PYR08 in 330 pages.-- 18th International Symposium on Analytical and Applied Pyrolysis held in Lanzarote - Canary Islands, Spain.-- May 18-23, 2008.Every other year, a group of scientists organizes this International Meeting that is among the most prestigious conference in the field. We are expecting that PYR08 in Lanzarote will continue the tradition as the premier forum for the presentation and discussion of cutting-edge scientific advances in basic and applied pyrolysis, setting the trend for the development of this discipline. This edition of the Symposium has exceptional exposure in fields like novel applications of pyrolysis in the environment and forensic sciences, the search for new materials, polymers, alternative energy source and in the structural elucidation of complex organic materials that may help in a better comprehension of the carbon cycle and Global Climatic Change. More than 200 top scientists and industry professionals from more that 30 countries from all over the world will attend PYR08. This edition has a very intense programme that include 10 Invited Key Lectures, 66 Oral and 180 Poster presentations.Ministerio de Ciencia e Innovación (MICINN) Consejo Superior de Investigaciones Científicas (CSIC) Gobierno de Canarias Cabildo Insular de Lanzarote Universidad de las Palmas de Gran Canaria (ULPGC) Universidad de la Laguna (ULL) Ayuntamiento de Teguise Centros de Arte, Cultura y Turismo de Lanzarote CDS Analytical Inc.
