“…The first is batch or flow apparatus used extensively in phase equilibria, thermodynamic analysis, kinetics, and salt or catalysts effect for organic matter in H-P and -T water, which measures after reaction [18][19][20][21][22][23][24][25][26]. The disadvantage of the method is that we cannot obtain in situ transformation to understand phase change and reaction mechanism of high pressure and temperature.…”

“…Water acted not only as the reaction medium, but also as a reactant, causing the oxidation of methylene groups. Shibasaki et al [116] degraded aromatic ethers in sub-and supercritical water between 250 and 430°C. Na 2 CO 3 was present as a catalyst.…”

The first International Symposium on Feedstock Recycling of Polymeric Materials (ISFR) was hosted in 1999 in Sendai, Japan. Since then, the ISFR has been held five times in different places in Asia and Europe. Each of these conferences focused on special issues covered by the Journal of Material Cycles and Waste Management. The topics included thermal processes with and without catalysts, wet processes in various solvents, the dehydrochlorination of PVC, mechanical recycling and separation techniques, as well as the treatment of biomaterials. This review is a compilation of the most interesting and important developments discussed at the ISFR during the last decade.

“…The gasification of waste plastic in supercritical water also attracted much attention. Supercritical water gasification of waste plastics and the model compounds (such as polyethylene) were investigated by many researchers (Watanabe et al, 1998;Watanabe et al, 2001;Shibasaki et al, 2004;Su et al, 2004;Takeshita et al, 2004;Su et al, 2007). The anaerobic organic wastewater from wheat straw includes acids (acetic acid, butyric acid) and ethanol etc.…”
