My toilet makes compost. It's a dry compost toilet. It simply and effectively turns our waste into usable compost that can be buried in the (non-vegetable) garden.
Here is a little introductory video to show you what it looks like and how it works.
Here's some of the reasons I love my composting toilet:
We save over 50,000 litres of water a year because it has no flush (that's comparing to an ultra-low-flow toilet flush. We'd save 100,000 in comparison to full flush toilets).
It uses almost no electricity - just a tiny fan inserted into the air vent which uses 5watts/hour (in our house this is solar powered).
It does not smell - because of the small fan in the vent pipe which ensures that any smell goes up the vent, not into the toilet room. It really does work!
It is a sealed system so insects and rodents cannot get in.
Because it does not smell and it is sealed, we have in our house - not as an outdoor toilet, like many compost toilets are.
It has no moving parts - very low-tech and easy to maintain.
It does not export our waste to be dealt with elsewhere.
It reduces the organic material by 90% - massively diminishing the volume of waste to deal with.
It requires no chemicals to process the waste.
It is a continuous composting system, as opposed to a batch system where you need to physically swap chambers. This reduces handling and heavy lifting.
It is approved by our local government plumbing department.
This is a super simple and effective waterless toilet. The toilet room and the finished compost do not smell.
Every few weeks we add a little extra high carbon material, like sawdust, to maintain the carbon-nitrogen balance.
We have thrown a few handfuls of composting worms into the system to add extra composting power.
