Not an easy thing if you are trying to make everything work. It is difficult to make a vented, liquid tight system – which is why commercial composting toilets are basically useless. If they deal with liquid they use heat – baked poop. I did design a very nice toilet for a client that circulated liquid as a spray that both denitrifies and allows for some evaporation (it was a handpump – similar to a flush handle and children especially enjoyed that feature). This was a permanent installation that is still in use 20 years later but was expensive. The venting was complex but was essentially a well designed chimney. It was a flip system (2 containers – each lasted one year allowing the previous years collection to be emptied after a year – a dry compost at that point).</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:black'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:black'>Ironically I think the bucket system is the best.
