Compost Toilet

{but were too afraid to ask}

What is a Urine Diverting Compost Toilet?

urine diverting dry toilet, or UDDT, is a dry toilet where the excrement and urine are collected separately without flush water. This has many advantages, such as lower water consumption, odour-free operation and pathogen reduction by drying. Dried feces and collected urine mixed with water can be used directly in the garden and in agriculture, mainly as a soil amendment and nutrient rich fertilizer. A UDDT is an example of a technology that can be used to realize a sustainable sanitary system so that wastewater treatment plants are less burdened with harmful cleaning agents such as chlorine, bleach and toilet blocks.

How does it work?

▶ you only use the toilet paper we provide!
▶ you sit a little further to the back than you are normally used to
▶ urine is collected in the front compartment and is separately disposed of
▶ after urinating flush one cup of water through the front compartment
▶ feces goes into the rear bucket
▶ to prevent bad odour and to activate the compost process, use one or two cups of the wooden sawdust to evenly cover the feces
▶ close the lid
▶ wash your hands

What goes where?

▶ take care to keep fluid waste in the front compartment only
▶ solid waste goes in the rear bucket
▶ toilet paper can also go into the rear bucket
▶ when finished evenly sprinkle one or two cups of sawdust over the solid waste
▶ hygienic wipes, sanitary pads and tampons are not naturally degradable,
do not dispose them in the toilet but in the waste bin

Sold Waste!
{feces, wooden sawdust, toilet paper, vomit}

fluid waste!
{urine, water, biodegradable/non-toxic soap}

Gentlemen, your attention please!

Always pee while sitting.
Make sure you sit a little further to the back, this make aiming a lot easier

Why all this trouble?

▶ flushing a toilet uses 6 to 9 liter of water each time
▶ on average a human visits the toilet 6 to 8 times a day
▶ that is 14.000 liter water per person per year
▶ meaning that over 25% of domestic waste water is flushed through the toilet
▶ toilets are mostly cleaned with environmentally unfriendly bleach or chlorine
▶ composting and gray water recycling produces no fluids that need treatment or require chemicals to stripped from it
▶ composting and gray water recycling produces nutrients and nitrates which can be used directly as food for trees and flowers

Doesn’t it smell?​

▶ as you follow the rules, no more than a flush toilet
▶ the secret lies in separating the poo from the pee. It’s the combination of these two that produces bad odours
▶ sawdust over faeces reduces odours
▶ the lemon acid and ethereal oils used in our urine flush water, disinfects and removes remaining smells
