The Night Soil Man

“Night Soil”, which is untreated, uncomposted human waste (aka poo) was commonly used as a fertiliser in the United Kingdom until around 60 years ago.

It’s still used in China and some other countries, but comes with risks as faeces can be a vector of human disease transmission.

Today, science has shown us that composting human manure will render it safe in addition to compost being generally better for the soil than manure (better structure, less nutrient run-off etc).

Using a compost toilet is not taking us backwards a hundred years, because we apply modern scientific rigour and know that composting is an essential and desirable aspect to dealing with human ‘waste’ and turning it into a safe and valuable resource.


  1. Up to sixty years ago they may have been removing raw sewage from toilets for agriculture but now have up to date analysis for our processing of human waste through our HH-2 units. No harmfull organisms or pathogens have ever been found in our end product, HH-4.

    • With all due respect, your HH2 system is incredibly expensive at £6k. For domestic-scale users, a ‘hot-bin’ compost bin would achieve the same results or am I missing something? There’s no real indication on your site of how your HH2 works, but it appears to be a pair of large, stainless steel insulated compost bins. A domestic user would have trouble filling that at a suitable rate for it to work, but I can see that where you have a number of compost toilets, a communal system like this would be useful, although currently in the UK, I do not know of any.
