While a camping toilet is still, in essence, the same as a regular toilet in your house, there are one or two significant differences that you should know about. As we've established, camping toilets do not dispose of your waste.  Instead, once you've finished doing your doing, the contents are deposited in the holding tank at the bottom for you to get rid of later.  Camping toilets use additives as human waste is not only a pollutant but also a health hazard. It is crucial that when nature calls, you can safely and hygienically do your business, and this is why you need additives in your camping toilet.  This is usually in the form of Aqua Kem Blue, which you pour a little bit into the tank every time you are ready to use it for the first time and will last for up to 5 days. The purpose of this additive is to break down the waste in your holding tank for easier emptying whilst also reducing odours and gas build-up.  In addition to Aqua Kem Blue, for number twos, you will also need some Aqua Rinse Plus (The Pink One), and this is basically your flush system (if you have a flushable toilet.) It also helps prevent limescale build-up and keeps your flush-water tank clean. Once you've finished on the toilet, you simply dispose of the bag (again, depending on the toilet type) or give it a flush, and it's on to the next adventure.
