How Does It best composting toilets work?
The principle behind composting toilets are very simple, the waste matter are allowed to decompose in a similar way to the garden waste in your garden composter. The main difference is in the material being composted.
For a composting toilet to work efficiently, three things are needed. Firstly, as the waste is 90% water a vent system is needed to allow the water to evaporate and any odors to dissipate.
The environment in which the waste is decomposing must be suitable so that the decomposition can take place quickly.
Finally, the finished compost must be safe and easy to handle. Modern, self-contained composting toilets are designed to deal with all these elements with the minimum of effort and input from the owner.
What Makes For a Good and best Composting Toilet?
There are two critical components of a good composting toilet. The first is that it must be able to properly seal the basin so that fumes are vented in an appropriate manner.
If you don’t have a good seal, then odors will escape and that’s a smell you’ll remember for a long time! You’ll also need to have a good stirring mechanism so the composting process can work right.
This can either be automatic or manual. If you’re looking to save a few bucks, go with the manual option.

How to install the best composting toilets
The three examples of composting toilets that we have reviewed are very simple to install. All that is needed is two brackets attached to the floor to secure the toilet in place. An electric supply, either 12v or 110v, is then needed to operate the extraction fan (and heater if fitted).
Many toilets have a pipe to vent the gasses and odors, so a hole may need to be drilled to route the pipe to the open air, and that is it. Before first use, the toilet needs to be filled with the appropriate amount of peat moss or sawdust and the toilet is then ready to use.
By the time that the toilet needs emptying, much of the unpleasant odors have dissipated and emptied the tray is not an unpleasant task.
Types of Composting Toilets
There are two basic types of composting toilets, self-contained units where the composting unit is part of the toilet and toilets where the composting unit is set away from the toilet.
To operate at it’s most efficient a composting toilet needs a power supply to operate a fan to remove excess gasses and odors. Some units have a heating attachment to speed up the composting action. Although this is not completely necessary it does make the toilet a lot more efficient.
Power can be supplied through a vehicle 12v system or through a standard 110v mains supply. Some toilets can have electric supplied via solar cells, making them truly independent of any external electricity or water.
There are other alternative composting toilets but these rely on natural decomposition and for many people are impractical due to the availability of sufficient land.

Best Composting Toilets | An Alternative Solution?
Turning body wastes into composts is not an unusual concept. Many centuries have passed and composting is still valuable especially for those who are environmentally conscious. Composting toilets or the CT carries out the same idea from the original pit latrine. This technology uses minimal or often times no water at all to flush your waste.
It is most often classified as a dry toilet system or a waterless toilet due to its efficiency in reducing water consumption. There are two variations for this toilet, the slow composting or otherwise called moldering toilets, and the active composters.
Composting Toilet Types
The first type, the slow composting, is the most common among the two since it does not require a lot of monitoring and maintenance.
These toilets literally take a long period to finish composting the waste since it lacks the normally warmer temperature in garden pits, hence the name.
It takes a few months on average for dangerous microorganisms to become destroyed with this type of composting except for the very notorious roundworm, which could take up to a decade.
For this reason, it is advisable to use the end product on ornamental flowers instead of food plants. Despite this, it is truly convenient for those who do not want to constantly deal with the waste because it would usually take two years before the chamber needs emptying.
The next variation of composting toilets, the active composters, has two classifications. The self-contained version means the process of composting your waste will take place in the toilet itself and is optionally added with exhaust fans and heaters to help speed up the biological processes.
Owners normally include materials such as sawdust to help reduce the unpleasant odor and increase absorption of moisture after usage.
The second type of active composters is the remote system where the composting bin is not inside the toilet but is rather in a specially dug hole in the ground underneath or near the garden. The waste is constantly being transferred to that pit where it decomposes.
They could either use little to no water to flush or be equipped with a vacuum. It is suitable for households with more than three persons because of the bigger space allocation for the wastes, although this requires a bit more monitoring to make sure that everything is smooth.
