I did think it would be worth tracking the progress of our composting toilet though, if only for my own record. At the moment we are running one toilet which is used by two people everyday and visitors as and when they feel the need; I know they use it as I have found myself explaining the mechanics of it to interested people, normally because they can’t believe that there is no smell even though we are collecting on mass the previous days food!
We are currently on our second composting pile if only because the first one I made, out of old car tyres, was a little small; however it is full and is now in a state of rest and turning turds into top soil. Our second pile was built in May 2012 and has provided storage for the summers offerings and is still less than three quarters full and that includes all non human processed waste items such as veg trimmings, weeds from the garden, uneaten food (not very often), paper, cardboard and even dead mice. With space to spare and the on-going composting process then I’m more than sure that this pile will last for the rest of the year.
The real beauty of the system is its simplicity, the only added requirement over a standard toilet is a ready supply of a cover material (we use sawdust) and about 5 minutes of time once a week to empty the poo onto the pile.
Remember every time you use a composting toilet you are not only saving the water you don’t flush, about 10 litres on average; you are also saving the additional resources used to clean that water before it can be sent off to sea or sent back into the system for us to use again.
