We really have to start talking about this vital subject. I am sure if others from outer space were looking at us wasting our most precious resource of water to flush away other important nutrients they would really think we were totally crazy.

So too the children 100 years in the future will not believe what we thought was normal today.

Every day
5 Billion gallons of expensively treated (potable) water are flushed away, so what can we a water saver and dont flush after a pee (until you can get your very own compost toilet)

Really in nature there is no such thing as waste so to call our toilet matter 'waste' is really using the wrong word. Instead it is a vital compost which also has the potential of creating gas and therefore energy.

The most simple system is a dry compost toilet and there are numerous kinds. More advanced is to look to anaerobic digestion. Both systems when looked after are free from odour, simple to use, protect our precious water supply and leave us with agricultural fertilizer.

Currently large scale agricultural systems depend on petroleum based fertilizers instead of what we all produce for free. This not only contaminates the land and water but continues the demand for petroleum products.

For an even simpler system....

The Tree-bog compost toilet takes its name from the fact that human compost, or 'humanure',  is a great fertiliser for trees and therefore not surprisingly trees growing close to composting toilets are particularly vigorous.

Unlike a conventional compost toilet, a tree bog should never need emptying. Effectively, it is a system for converting human fæces to biomass. The tree bog combines resource production and waste disposal and functions by transforming fæces and urine into growing trees and organic soil. 

A beautiful, waterless compost loo, that helps trees to grow too!


London just held a toilet festival
where the following questions were asked regarding city sized systems... How would you collect the waste? It used to be the nightsoil man, but what would the alternative be in a contemporary city? Where would the collection points be? How would you effectively harvest the nutrients? Where would the fertilizer be distributed to? How would you stop it from smelling? How would you keep it hygienic? Who would manage it? How many people would need to change their toilet system to make this a viable option? Would other people also see it as a better option? What would make people change their toilet system when most people don’t even think about where the water comes from and where the waste goes?
