    Human waste is a fantastic product. As they say “Where there is muck there is brass” Fermenting human waste produces between 120 to 135 gallons of Ethanol per ton. The resulting solids can be dried and burnt. It has a higher calorific value than mined coal. Anyone interested in funding a pilot plant email:

    0.2 liters of water shall not always keep the toilet CLEAN ENOUGH for the use by other person I think.

    So, basically like an airplane toilet, how self contained is it, or is it like others are saying and a city retrofit is needed

    I reckon you have to connect all the toilets in the city to the vacuum system, so a complete retro fit to a city is required. I think the investment on that will suck unfortunately.

    In my personal experience working in plumbing is that 0.2 L could not be enough, I am doubtful there, but great concept idea and i like what they’re trying to accomplish.

    Does this mean that the sewer system has to have separate pipes to transport the solid and liquid wastes? Can existing buildings be retrofitted with these kinds of toilets?

    Um, pretty sure that grey water stops being grey water if it is used to flush a toilet. Thus the need for treatment. That said, excellent progress.
