When you are land-based you have more choice than if your toilet is on a moving ‘platform’ such as vans or boats. Whilst you can use an internal bottle to capture the urine (for use as a fertilisers, for example), you can also divert the urine too outside the room to either an external, larger, tank or to a soak pit.
Urine is a very good garden fertiliser if watered down 8-1 or more but can easily and safely be disposed of anywhere in the garden if there isn’t a water-course within ten meters.
Another option you will have is to dig, what is know as, as ‘soak-pit’ – a gravel-filled hole in the ground into which you divert the urine. In the scale microbes grow on the surface off the gravel that are effective at digesting the nutrients and minerals leaving cleaner water to leach into the surrounding soil.
If you have a garden then you can have your own ‘humanure’ compost bin. ‘Poo’ when mixed with a carbon material such as straw or sawdust will compost down very well and can then be used around the base of many garden and woodland plants/trees. The recommended compost period is two years but this can be much faster if you ‘hot’ compost using insulated containers. To have a humane compost system it’s recommended that you have two compost bins – each of which with the capacity to last two years (more on this later). To operate this system you follow this routine:
- Year 1 & 2 fill compost bin A.
- Year 3 & 4 start filling compost bin B and then monitor bin A to make sure it isn’t too dry or wet (add more moisture or carbon accordingly)
- Year 5: Empty bin A and use the contents
How much composting space do I need?
Not a lot! A family of four will only need around 300L for a year – and thats if they don’t ‘go’ anywhere else. A double chamber compost bin will easily last the two years you need.
