Why you should separate liquids and solids in a composting toilet

One question that often comes up when researching composting toilets and DIY solutions: do I really need to separate liquids and solids? 

Let us start out by saying: We don’t force you to do anything. But, we’ve been there, our olfactory sensory neurons aren’t the same they used to be and we highly recommend separating liquids and solids in a composting toilet. 

Keeping liquids out of the composting part of the toilet makes for an odor-free composting experience, easy maintenance and simple cleaning. Dry solids (as in poop and compostable toilet paper) don’t smell, and a covering material helps with keeping the solids dry and odor-free. 

By separating the solids and the liquids you can also stretch the time between having to empty the toilet significantly. 

One common issue with off-the-shelf composting toilet is an inadequate separation between solids and liquids. The pee enters the solids bucket, introducing excess moisture and causing that dump-station-burp smell. Nobody likes that smell. It’s one of the reasons we said goodbye to black tanks in the first place. Plus, it adds all kinds of additional issues, from trouble cleaning the toilet, where to dispose of the slush, and moisture-loving flies and other pests. 

Getting a good separation isn’t as easy as it sounds, and we’ve put years of R&D into perfecting our THRONE urine diverter to achieve exactly that: a reliable separation of liquids and solids taking into account well-hydrated users, anatomical differences and the next generation of composting toilet users. You can also teach your cat how to use it, but we do not vouch for perfect separation in this case.
