Systems vary but basically waste is collected from holding tanks in buildings deposited in large ‘ponds’ or containment and various treatments and amendments are used and within 30-90 days typically is used as an amendment. Fishponds were traditionally used and this was common in germany until the 40’s.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Gastro intestinal risks are high viral and bacterial less so but still significant what is probably the biggest potential future concern may be chemicals that we consume and form part of our wastewater (pharmaceutical, metals , etc.) and our farmed soils concentrating those loads.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>So the question goes back to how do we best derive energy from our waste (basic recycling question) without further contamination. Does it matter what form the energy takes and how it is used within a community? If health is a criteria then it does matter as food is now global and bacterial and viral infections such as cholera, typhoid, Hep A are not limited to a hundred mile diet. If the health of the soil is a criteria then it also matters. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>The energy from our waste will at some point be utilized – questions of recycling are about utilizing it sooner which means taking advantage of it as an ‘economic’ benefit – I think the real concern is the amount of contamination we introduce and how that can be contained and the developed world is the major problem for this.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>A toilet for north America that turns feces and urine into hydrogen fuel cells and recycles the water for the next flush – better than a Toto pumping into a sewer system.
