Cassette Toilet Vs Composting Toilet

A cassette toilet is emptied at a dump point after a tank of chemicals breaks down all waste. One tank is used for liquid waste, while the other is used for solid waste in composting toilets. Wood shavings or peat moss are used to compost solid waste.

Composting toilets and cassette toilets are two ways to manage waste that are eco-friendly, efficient and help the environment. The reasons why one might be better for you than another will also be explained. In addition to providing some tips on choosing which is best for you, we’ll discuss the advantages and disadvantages of both options;

Cassette Toilet Vs Composting Toilet

In a cassette toilet and composting toilet, the black tank contains all the waste, but the removable waste tank can be dumped when full. Portable toilets can be a great alternative to conventional toilets. There are many factors to consider and options to choose from. As opposed to composting toilets, cassette toilets mix all waste in one removable tank and compost it while composting toilets keep solid and liquid waste separate.

Difference Between Cassette And Composite Toilet

Similar to stationary toilets for vehicles, cassette toilets can be found in vehicles. You can flush them and even have them installed because they have an extra clean water tank inside. Unlike an RV toilet attached to the RV, the waste from an RV toilet goes into the black water tank.

There is no need to dump it until you reach a dump station. There is also a miniature, portable version of that waste tank on the cassette toilet where liquids, solids and chemicals must be mixed and disposed of by hand more frequently.

The bowl and lid are the most important parts of any toilet. In terms of flushing systems and storage, they will be different. The two are also easily distinguishable in appearance and design.  Cassette toilets are bench-style toilets designed for RVs.

Functionality Mechanism

In terms of functionality, the two toilets differ primarily. Solid and liquid waste are kept separate in composting toilets. There are two waste tanks, one for solids and one for liquids and both can be removed. Solids flow into one container while liquids flow into another.

Composting medium is provided at the bottom of the solid waste tank. Peat moss or sawdust can be used for composting. As an exhaust fan, a fan blows air on the waste and out the RV, causing it to dry out. This forces the odor to exit the RV as well. However, the liquid is collected and disposed of in dumping stations or comfort rooms.

As compared to cassette toilets which have one waste tank for solid and liquid waste, cassette toilets use no separation technique. Using water to flush the toilet eliminates waste is also a feature.

The waste tank can be removed once it’s full then dumped in designated dumping stations. Although there are dozens of dumping sites around the world, they are not readily accessible.  You may be charged a fee for certain of these or they may be exclusive to camping guests. Burying waste properly is an option, but double-check your local laws before you do so.

Water And Energy Consumptions

Composting and cassette toilets differ in certain aspects of cost-effectiveness and eco-friendliness. When it comes to being eco-friendly and saving water, composting toilets win. In big cities or in RVs that are too small, this composting toilet is a lifesaver.

It is generally not detrimental to the environment and aids in the natural composting of waste without chemical additives. While helping the planet conserve water, it does not require water. Despite this, cassette toilets might be at a disadvantage energy-wise since solid waste is blown out of the toilet using an exhaust fan.

Cassette toilets may not be as eco-friendly as composting toilets. Despite this, it can still conserve energy since it uses the traditional flushing system that needs no energy to operate. The volume you can hold in most cassette toilets is limited. Therefore, you must empty them periodically.

You would find a valve on the cassette toilet when you go to the bathroom. The waste or its contents can flow into the tank and be stored there until they are removed and disposed of. A light indicator will usually appear when the cassette is full.


As composite toilets last longer so it does not demand any kind of construction once you have successfully installed it. The price of a composite toilet is less than $1000. A few of them have $1000 but they are used for big companies.

Compared to composite toilets, cassette toilets price is low but at the same time it frequently demands maintenance but puts a burden on the pocket. Its price starts from $100 and can range up to $800. It does not last as long as composite toilets because you have to pay money from time to time for its maintenance.


Traditional flush toilets can be replaced by composting toilets or cassette toilets. In addition to being more efficient, eco-friendly, portable, and affordable, they are also more cost-effective than traditional toilets. You will need to consider your individual needs and preferences when choosing between a composting toilet and a cassette toilet.
