How do they work?
Composting toilets function similarly to your household toilet, except they do not flush valuable water resources into overburdened and outdated water treatment plants.
Instead they create a safely contained and odourless catchment area, facilitating the natural process of microorganisms to decompose human waste into compost. They effectively separate urine and solid waste and use a covering material like wood shavings or coconut coir to absorb moisture, eliminate smells and add essential carbon into the compost mix to begin the process immediately.. Once the composting process is complete, the result is a safe to handle, nutrient-rich compost that can be utilized for on hedgerows, trees, plants or for soil enrichment, providing an eco-friendly waste management solution for off-grid areas and environmentally conscious individuals, without the unnecessary flushing away of thousands of litres of fresh (and expensive) drinking water!
Over the past 3-4 years, we have been building compost toilets for customers all over the UK, developing two different designs that function exceptionally well for your campsite or dwelling, catering to your specific capacity needs. Our installations require no plumbing or electricity, making them an easy, hassle free and sustainable addition to your outdoor space.

The Wheelie Green
A user-friendly, low-maintenance system, that requires no electricity or water to install and manage.
These designs incorporate a wheelie bin for solids waste containers because they work perfectly as a robust and easily transportable vessel for compost.
To enhance the composting process, we utilize a liquid separator, redirecting urine into a gravel-filled soakaway. We supply each toilet with its first bucket of saw shavings to use to cover after each use, the result is a dry, odourless compost end product.
A clear insulated roof and standing height window allows natural light to flood into buildings and we can also install solar lighting upon request.
All our buildings are designed and built to be spacious, comfortable, warm and welcoming. Unlike over composting toilets available we like to maximise the internal space not minimise it, making using a Nature’s Calling Composting Toilet, made from natural sustainable materials, as different as experience to a using a plastic portaloo as possible.

Our ever improving designs now include sealed and vented bins which remove any potential smells and allow for the composting process to totally happen within the bin once its full.
This also stops and traps any flies that might be sniffing about!
Not an essential addition to a compost toilet but give any user peace of mind that even if the previous user has misused the toilet, by adding too much paper and not enough cover material for example. Bad smells are sealed away from the cubicle and extracted high above the building and away from your noses, just remember to shut the lid.
Extra Wheelie Bins
Increase your capacity of any toilet. The aim is to have enough wheelie bins to last you a yearly cycle of producing free compost. You may need just 2 or you may need 6 or 7.
You can of course always just empty the bins as soon as they become full, but if you have enough bins to wait till the following year the compost process should have begun making it much less daunting task. Or if you choose to add our vented extraction chimney to your toilet and bins the compost process should already be complete!
Talk to us to us about your site and we can roughly calculate how many bins you will need.
Extra wheelie bin unvented - £60
Extra wheelie bin with vents - £80
