We have former biomass gasifier sites that have been legally “superfund sites” or toxic waste sites and were cleaned up. There are also many studies of former gasifiers and brick kilns in developed and developing countries where the toxic soup still exists. In Myanmar last year the president announced that water toxicity from biomass gasifier scrubbers had become a significant health problem in Myanmar an so he decreed that the countries engineers would have to deal with it. These are very low cost knockoffs of the Chinese and Indian gasifiers. Running the scrubber water into a pond is not a solution. <o:p></o:p></span></p><p class=MsoNormal style='background:white'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal style='background:white'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Tom <o:p></o:p></span></p><p class=MsoNormal style='background:white'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal style='background:white'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p></div></div></div></div></body></html>
