Want to install a composting toilet upstairs or in a basement? You can! The best solution for installation below/above the ground floor is a self-contained zero leachate system.
If you have a urine-collecting system in which urine is gathered in a container separate to the composting chamber, you will need to dispose of the urine manually once your container is full.
Additives help you maintain microbial activity within the pile, speed up decomposition, balance out pH levels, prevent fly strike, negate damaging effects of pharmaceuticals on the compost, and generally prevent problems from arising.
Composting toilets are designed to keep flies away, and with proper maintenance flies shouldn't be a problem. If, however, you've found flies buzzing around your toilet, you need to deal with them sooner rather than later.
A well-designed and properly maintained toilet shouldn't have any unpleasant odours. If it does, something is wrong. Here are a few reasons as to why a composting toilet may start to generate odour, and ways to fix it.
