For the best long-term results, look for toilets that meet or exceed current standards from the American National Standards Institute or a similar international organization.
Composting Toilet Cons
People with conditions that restrict their mobility may find composting toilets uncomfortable to use, as the toilet requires them to squat too low. Some model, especially the self-contained composting toilets, may not contain odor so well.
How to Choose a Composting Toilet
Do you need a composting toilet for use at home or one that you can use on the go If you don’t have a water supply at the location of use, you should get a model that doesn’t require any water to operate. There are several other considerations that you need to make while shopping for the best compost toilet.
Composting Toilet Type
You have to ascertain the type of compost toilet that will be ideal for your intended use.
While choosing the right toilet, these are the 5 main compost toilet types you should consider:
These are the composting toilets that do not require any water to function. The dry composting toilets that have a flushing system use a negligible amount of water.
These toilets are odorless, so they are considered to be ideal for indoor application, such as household interior.
These feature a compact and more portable design. Self-decomposing toilets have a compost system just below the bowl.
Such a product is best suited for hiking or camping applications. Self-composting toilets are generally designed for use on the go.
Electric Composting Toilets
With such toilets, the composting system features components that need electricity to run.
Most of these models have an electric fan to continuously circulate air in the composting unit. Some electric composting toilets require a connection to a mains outlet, while others can run on a battery.
Electric composting toilets are known to be more efficient and faster at the decomposing human waste. However, such toilets are comparatively more expensive.
You should consider getting a battery-operated unit if you are not connected to the grid, or you could opt for a non-electric model.
Non-Electric Composting Toilets
Compared to electric composting toilets, non-electric models are generally low priced.
For the composting process to function, most non-electric toilets require you to manually mix the waste using a built-in crank.
Compared to electric models, composting toilets are slower and less efficient at composting human waste, . Still, they are a great choice in some applications.
Remote/Central Composting Toilets
Rather than encompassing the composting unit below the bowl, these toilets channel the waste to a composter separate from the toilet.
Remote composting toilets are a great choice if you would like to use several toilets in the same location. In such a case, you can connect several central composting toilets to one composter.
Composting Toilet Capacity
How much waste a composter can hold depends on the toilet you buy.
The right composting toilet capacity mainly depends on the intended application. For example, toilets meant for use on the go don’t need to have a large capacity.
Though lightweight and more portable, toilets with less capacity need to be emptied more frequently. Consider the number of people that will be using the toilet, and how often they will be using it.
There are no federal or national laws governing the suitability and application of composting toilets. Different state, county, and municipalities have varying zoning requirements.
Before you buy a composting toilet, ensure that it meets the zoning requirements in your area. Contact your town or county to inquire about the building laws that may affect the use of composting toilets.
In order to maintain the composting process, some toilets require you to add bulking material. Bulking material is essential for breaking the waste down to allow for free air circulation. Some composting toilet models do not require the use of bulking material. Using bulking material in such a toilet could damage it.
Bowl Closure & Toilet Trap Mechanism
Regardless of where you will be using your compost toilet, sanitation and odor is something consider. To maintain the best sanitation and prevent odor, you should get a toilet with a good compost trap design.
Different toilets have different mechanisms for locking the composting receptacle or waste line from the bottom of the basin. If you do not want to operate the closure mechanism, you should choose a model that has an automatic trap closing mechanism.
Other models feature a manual valve that needs to be operated manually. Ensure that the closing mechanism on your preferred toilet is durable, effective, and reliable.
