  • Wear a mask (everyone should now have several of these thanks to COVID!)
  • Wash your hands after handling
  • Wash your clothes after handling

What to do with the waste from a composting toilet

Once you’ve used your composting toilet for some time, you’re going to have a byproduct that’s very much like topsoil. This can be used in a variety of different ways:-

  • Add it to an existing compost pile
  • Spread it around fruit or nut trees
  • Spread it over lawns
  • Spread it around non-edible gardens

It’s essential to note there are some plant types you should not use humanure on. These include:- 

  • Do not use on edible plants
  • Do not use on Herbs
  • Do not use on Vegetables
  • Do not use on edible flowers or plants used for seeds (sunflower, pumpkins, sesame, chia, etc.)

As you can see, there are a few things to think about when installing a composting toilet in your tiny home, but at the end of the day, it’s like anything in life. Once you’ve done it a few times, you get used to different ways of doing things. 

One of the most significant changes in many of our customers’ experience is the mindset of being responsible for your own waste and the impact on the environment around you. When you start living a little closer to nature, you realise just how important it is to be kind to our planet, and one of the easiest ways to do this is to install a composting toilet!!
