Energy recovery environmentally degradable

Releases of aniline in industrialized countries is considerable. According to the US Toxic Release Inventory, during 1998, eighty-two factories in the US released 1,449,754 lbs. of aniline, 217,223 to the atmosphere, 19,549 to surface waters, 1,161,911 by underground injection, 252 to land and 50,819 to disposal sites. While aniline waste is nowadays subjected to recovery, management, energy recovery and waste treatment, this was not so in the past, when anilines caused environmental injuries. The toxic impact of many dyes, e.g. in waste streams and releases to surface waters, arises from the fact that they are degraded, cleaved or reduced to aromatic amines. 

Pyrolysis in supercritical water [67, 68] owing to the many special characteristics of supercritical water, waste plastics can be degraded efficiently in supercritical water, which has recently received great attention has been studied comprehensively. This technology can not only realize the recovery of valuable products from waste plastics, but also provide a solution to the ever-growing energy crisis and environmental pollution. No catalysts or reaction agents are needed here, so the cost is very low.
