Humanure

According to the humanure ‘philosophy’, urine is an essential ingredient in the compost process. Human urine contains nitrogen roughly equivalent to the amount used in agriculture to grow our food. The humanure approach says put it in the heap with everything else, it is the vital ingredient to the hot compost needed to render human manure safe, it being a great ‘activator’.

There is another school of thought which argues that urine is such wonderful stuff on its own that you should separate it and use it on plants. This then would mean that you can only cold compost the poo, which means it will not be safe on food plants.

There’s no reason why you couldn’t do both. Keep a bit of pee on one side by peeing into a plastic bottle which you can mix 1-10 with water when you are watering your plants, and the rest of your doings go into the compost heap. Urine usually contains 90% of the nitrogen in your excreta.
