The incineration control method heats a smoke and soot removing filler layer to a smoke and soot removing temperature not lower than 350°C by actuating a filler heating heater in response to input of a treatment start signal, carries out an incineration treatment by actuating an incinerating heater and an exhaust blower when a temperature of the smoke and soot removing filler layer has risen to a smoke and soot removing temperature, stops the incinerating heater and the filler heating heater when a temperature of an incineration chamber rises to a preset incineration treatment end temperature, and stops the exhaust blower when a temperature in the elec- tric incinerating toilet bowl has dropped to a preset ex- haust end temperature after the stop of the incinerating heater.

Although there are many ways of treating human excreta, composting is often regarded as the best solution because the final result of this treatment is valuable humus. However, human urine contains the most of the nutrients, so it may be more reasonable to apply human urine alone as a fertilizer. Direct utilization of urine emerges a lot of problems, but there are several existing technologies which are able to recover the nutrients from urine. These technologies (stripping, absorption, struvite precipitation and membrane technologies) also capable to recover nutrients from wastewater. Our paper are focusing on the comparison of composting toilet and urine-diversion toilet by analysing the advantages and disadvantages of the two methods.

  • Incinerating Toilets (From Issue 10)
    Incinerating Toilets (From Issue 10) What do you do when there is no way to repair an onsite system because of restricted space or other severe limitations? Many Boards of Health have recently inquired about alternative toilets that have no discharge. As you recall, in the past we devoted an entire issue to composting toilets. But these toilets, which must be designed to store compost for at least 2 years (310 CMR 15.289(3)(a)) are often larger than can be accommodated in tight situations. In this issue, we feature incinerating toilets (which gives new meaning to the expression "hot stuff"). Incinerating toilets should be considered in situations where all other standard options have been exhausted, and in which there is very limited area available for a leaching facility. Examples of such situations are barrier beaches, tiny lots near the shore, dune shacks, and living units on piers or docks. Approximately 600 electric and a fewer number of gas incinerating toilets have been installed in New England. But, before we get started, let's start with the basics. WHAT IS AN INCINERATING TOILET? Figure 1. Typical electric toilet installation by Incinolet® Incinerating toilets are self contained waterless systems that do not require being hooked-up to a sewer system or inground septic system (except to dispose of graywater). They rely on electric power or natural or propane gas to incinerate human waste to sterile clean ash. When properly installed these systems are simple to use, safe, clean and relatively easy to maintain. Figure 1 shows a typical configuration of an electric toilet, and Figure 2 shows a schemata of a typical gas toilet installation.
