Green Toilet Lux 120

The Green Toilet Lux is an innovative composting toilet designed for indoor use, featuring a stylish porcelain pedestal. This makes it an aesthetically pleasing and functional choice for seasonal-use holiday homes, cabins, tiny houses as well as for year-round residences. It offers a user-friendly experience, mirroring the familiar comfort and convenience of normal flush toilets, thereby eliminating the need for special how-to-use instructions.

The are two basic models of the Green Toilet Lux composting toilets. The smaller Green Toilet Lux 120 is called "the family model" due to it's intended 2-4 people user capacity. There is also a larger Green Toilet Lux 330 available for full-time, year-around residences, larger families and public use cases.

The great thing about the Green Toilet Lux 120 composting toilet is that it is a split-system, batch composting toilet. Find the video above and read description to learn more!

Split-system Design

The Green Toilet Lux composting toilets fall in to the category of split-system composting toilets, meaning there is an external composting container underneath the toilet floor level. In the case of the Green Toilet Lux 120 the minimum space requirement under the floor level is 28 inches.

The composting toilet container under floor is the Green Toilet composting toilet container designed and made in Finland, Scandinavia.

There are a number of advantages to split-system composting toilets:

• Generally, split-systems like the Green Toilet Lux have greater user capacity and therefore longer service intervals. In other words, the toilet needs to be serviced less often.
• For split-system composting toilets we offer a sleek and shiny porcelain-made dry toilet pedestal that looks and feels just like the conventional toilet.
• Split-systems also have the advantage that the bathroom usually stays intact during the service of the toilet

We offer several composting toilets with the split-system structure. To find out the clearance needed, please refer to this chart of split models.

Batch Composting

The GT Lux 120 comes with two 120-liter (approx. 31-gallon) special composting containers that separate liquid from the solid compost mass within the composting containers. Of the two composting containers, one is intended to be in use while the other is finishing composting outside.

When one Green Toilet composting container fills up, the second container can be put into use immediately to enable continuous use of the toilet. By the time the second container has also filled up, the first one should ready with composting process and can be emptied for example into a garden. This principle of switching composting containers is called batch composting and therefore the Green Toilet belongs to the category of batch composting toilets.

The great thing about batch composting and spare containers is that they enable extended capacity if needed. Quite often it is difficult to estimate precisely how much composting capacity (volume) is needed to manage waste of X number of persons before few years of use history. Batch composting toilets offer flexibility in this as more composting containers can be acquired when and if needed.

You can find extra Green Toilet 120 composting containers for your Green Toilet Lux 120 composting toilets separately from us. Please note that any new Green Toilet Lux 120 composting toilet packages come with two composting containers so you will at least have one spare container with the basic package.

Use of the GT Lux

The Green Toilet Lux is used just like a normal flush toilet, except that it is not flushed. You sit down on the toilet and do you thing just like you normally would do. Male users may also urinate standing if desired.

All waste, including urine and toilet papers, simply fall through a waste pipe connecting the toilet into the composting container below floor level.

How the Green Toilet Lux works

As the waste falls down into the composting container below floor level, all solids (poop and toilet paper) will land on a double base layer inside the Green Toilet container. Most of the urine will get absorbed into the solids and evaporate through the ventilation of the container by time.

However, if there is more urine (or other liquid) falling into the composting container, it passes through the solids and the double base onto the bottom of the Green Toilet container.

This double base design efficiently separates surplus liquid (urine) from solid waste, initiating the composting process right from the start. While majority of the urine gets absorbed into the compost mass, the excess will fall through the double base to the bottom of the container. From there, the excess urine can be lead to a canister or a special filter with a hose supplied in the package.

The double base design is essential for the odorless operation and effective composting process of the toilet. This way there is no need to separate the urine in the toilet seat (a.k.a. urine-diverting toilets), like in many other waterless toilets on the market.

During the use of the dry toilet, dry material like hemp or peat is added after every use 1-2 dl. Alternatively, dry material can be added separately 1-2 times a week a larger amount, about 5-10 liters.

Cleaning the toilet pedestal

The porcelain pedestal can be washed with little water, a toilet brush and biodegradable detergent, if needed for example once per week. Please note that usually the porcelain pedestal stays clean by itself after use. Rarely there are any marks of use after using the toilet.

Servicing the Green Toilet

The Green Toilet Lux operates on a batch composting principle, meaning there is a swap made to a spare container once the current one is full. The filled container is then sealed with a closed lid and set aside outside for further composting process. While idling, the compost will mature into rich, nutritious mulch over 6 to 12 months, depending on environmental factors.

For convenience, the Green Toilet containers are designed with wheels, making them simple to transport and manage.

When the Green Toilet composting container becomes full, the other empty container is taken into use.

Liquids management

Generally majority of urine will get absorbed into the compost mass inside the Green Toilet and evaporate from there through the ventilation.

However, if there is more urine (or other liquids e.g. after washing the toilet pedestal with water) it passes thought the double base onto the bottom of the Green Toilet container. From there the so-called excess liquids are usually collected into a 5-gallon canister.

We recommend to regularly check the canister to see the level of liquids in it. When the canister fills up, it can be emptied for example into the other spare composting container (assuming it is full of compost). Alternatively, assuming there are no nearby water areas right next to, the excess liquids can be spread around from non-edible plants that can reuse the nutrients as fertilizer.

Please note that any liquids should not be directly poured in ground if there are nearby water areas (lakes, ponds, rivers etc.) or high water levels that could damage from the excess liquids.
