How composting toilets work

As much as you may have already chosen a compost toilet, it is also good to know how it works. As mentioned earlier, composting toilets convert waste into compost manure that can be used for other purposes.

For a compost toilet to work effectively, it will need a ventilator, urine diver, and a bulking material such as sawdust. The ventilation is to get rid of any additional moisture that may interfere with the decomposition process. The urine diverter is to divert the urine since it has high water content, which, when mixed with solid waste, will lead to a pungent smell. Bulking material is for creating an air gap that will help in the decomposition process.

Types of composting toilets

Since you already know how composting toilets work, it is vital to know the different types of composting toilets on the market. Composting toilets can either be slow composting or commercial active composting.

Slow composting toilets are also known as homemade composting toilets. They are the basic types, and they simply consist of a bucket and toilet seat rim. Since they are basic, they do not have any additional ventilation or a system to process the waste’s breakdown. Most of the time, they are cheaper, though you will have to deal with the waste more often. They are also likely to have odors unless they are adequately sealed or cleaned.

Commercial active composting toilets are an advanced version of the other basic ones. They both have a traditional toilet seat and a composting chamber for the waste. Most have a urine diverter for the urine so that it separates the matter successfully. They are pricier since they are advanced and look like other regular flush toilets.

How to choose a composting toilet

Since you already know a bit about composting toilets, it is good to know how to choose one so that you end up with the best one for your needs. Some of the factors to consider when you are looking for a composting toilet include:

Where will it be used?

It is good to consider the size of the space you have, and where you plan to use the toilet. It needs to be just the right size for your space such that it is not too big or too small.

Frequency of using it

Do you plan to use the toilet part-time or full time? That can help you choose the best one. It is also good to consider the number of people that will be using it. More people mean that you need a big capacity toilet so that you don’t have to change it so often.

Mode of operation

Composting toilets can either be manual, semi-automatic, or fully automatic. It all depends on what you prefer. Some units will also require more attention as compared to others. Small units, for example, need more frequent emptying.

Operational requirements

Different units have different operational requirements. Some are electric, non-electric, or solar operated. If they are electrical, you need to consider the voltage used. The standard options are 120V, 12V, solar, or none.

When it comes to cleanliness and maintenance of the toilet, it depends on the unit. The frequency of cleaning, emptying the compost, and operating the compost mixing feature, etc. depends on the design, frequency of use, toilet capacity, etc.

When it comes to bulking material, different toilets have their requirements. The common materials used are sawdust, moss, peat, and wood chips. It is good to know before the compost material that can be used.

Features of the toilet

Different systems have different features. It all depends on your requirements for your house. There are even those that have an inbuilt ventilating fan. Some types have continuous processing while those that do batch processing. Different toilets have different toilet bowl closure techniques. The bowl and the composter have different separation techniques, and that influences a lot of other things such as the odor.

Regulations

It is good to know if there is any legislation regarding compost toilets in your area so that you are not found on the wrong side of the law.

Price

Compost Toilets come at different prices depending on the features that come with it. The more advanced and more features, the more expensive it will be. Many advanced types usually are more expensive.

Reviews

When you go through user reviews, you will get a glimpse of what experience the unit gives, and that can help you know if it will suit your requirements. If many customers had a good experience with the toilet, you are also likely to have a good experience.

Electric Vs. Non-electric Toilets

Most electric compost toilets have an inbuilt heater that aids in the composting process. They also have a ventilation system and a system that can mix air and compost to aid in the aerobic breakdown of the waste. Some non-electric toilets have a ventilation system, but for sure, they will not have a heater and automated mixing.

Part-time vs. Full-time toilets

Part-time or full time does not depend on one’s definition but instead, how long one plans to use the toilet. A full-time toilet works as the main toilet for the house as it is used throughout the day. On the other hand, a part-time toilet is used only a few hours of the day or as an emergency toilet.

Water and electricity for toilets

Contrary to expectations, not all composting toilets are waterless. As much as there is the waterless type, there are also low water or foam flush types. If you go for a water model, you will need a water source. For those that are electrical type, they will need electricity or a 12V battery. There are also those that use solar power and the basic type that uses nothing. If you want the advanced kind with fans, automatic mixing, and aeration, you are obliged to go for the electric type.

Composting toilet process

Composting toilet processing is in different stages, mainly worm processing, micro-organism processing, and dehydration through evaporation. The composting process can either be in a batch process or a continuous system. The batch system is where when the composting department is full; it is emptied. Continuous composting is whereby waste is continuously taken to a single container. The composting process will reduce the waste volume, and the compost container can be emptied after a long time.

Maintenance of a composting toilet.

When it comes to maintaining a unit, it depends on the type that you settled for. The basic manual types that do not use any heater or aerator will need more maintenance as they are likely to have more liquid accumulation, insects, odors, etc. The advanced units are much better as they have automated mixers, have fans, heaters, etc.; thus, you don’t have to do much. Of course, you will be obliged to do a maintenance check from time to time to ensure that everything works well.

Conclusion

A composting toilet will serve you well only if you settle down on the right one. When you do a research and comparison and have the above information, then you are likely to find what you need.
