GL 90

The GL 90 composting toilet is a sustainable choice for off-grid sanitation. This split system toilet features a stylish porcelain pedestal in the bathroom. It connects to a composting container located below floor level. When full, you simply swap the container with a spare one. This design is perfect for areas with limited space beneath the toilet.

Unlike traditional flush toilets, the GL 90 doesn't require flushing. All maintenance is done outdoors, keeping your indoor spaces clean. Using batch composting, servicing the GL 90 is straightforward and clean. When a container fills up, you seal it and leave it to compost. Then, replace it with a fresh one.

Once filled, the compost from the first container turns into humus or mulch. This can be reused in gardens or safely disposed of. You can expand the system's capacity by adding more containers as needed.

Key Benefits

Split System and Batch Composting

The GL 90 features a split system that keeps the composting unit separate from the toilet, ensuring clean indoor spaces. Users can easily swap full containers for empty ones, streamlining service and enhancing compost quality over time.

Adaptable Capacity for Diverse Needs

The GL 90 is ideal for a variety of settings, from holiday homes to AirBnB rentals. It operates just like a regular toilet but doesn’t require flushing. This simplicity prevents misuse and eliminates the need for detailed instructions. You can also expand its capacity by adding more containers as needed.

Advanced Odor Management and Ventilation

The GL series offers an odor-free experience, thanks to its efficient ventilation system. This system expels odors and enhances the composting process by ensuring proper airflow.

Efficient Moisture Control

The GL 90 features containers designed with a double base and a capillary tray. This setup separates excess liquid from solid waste, maintaining optimal moisture for composting and ensuring an odorless experience.

User-Friendly Service

Servicing the GL 90 is straightforward. It involves leveling the compost inside the container to prevent waste buildup. Once a container is full, it is replaced with a spare one. This simple swap is the foundation of batch composting.

Using the GL 90

The GL 90 composting toilet operates like a conventional toilet but without the need for flushing. All waste and toilet paper fall directly into the composting container below.

Inside the container, darkness conceals the waste, ensuring no visibility. Additionally, the built-in ventilation system in the composting container eliminates any odors, maintaining a fresh environment above.

GL 90 use

After each use, it’s advisable to sprinkle a cupful of covering material, like hemp, over the waste through the toilet seat. You can also opt to add a larger quantity of covering material less often, such as weekly. To enhance the composting process, occasionally stir and level the compost to facilitate a more efficient breakdown.

Please remember not to dispose of plastic items, like sanitary towels, in the composting container. These should be thrown into a separate bin as they are non-compostable.

Installation and Service

There are two main ways to install and service the GL 90 composting toilet. In general the GL 90 composting container has to be installed directly below the toilet pedestal installed inside. Depending on clearance height below the floor-level, the toilet can be installed and serviced either in such a way that the container is pulled out all together with the lid and the waste shaft (Option 1), or by leaving the waste shaft and the lid in place (Option 2). The option number 2 is generally more common.

excellent

We are pleased to hear of Greenloo’s expansion to Canada/US markets. We are very happy with our GL 90 maximizer composting toilet. Instructions followed make a comfortable and sophisticated toilet situation. The unit was well received (exception whirlybird fan option was slightly damaged - not Greenloo fault - aside from shipping damage we needed to remove and reinstall the fan’s interior veins as they were upside down? Just so you know).
We live in a rural area, off grid and the two of us provide the Greenloo continuous use as we live here full time. It is an excellent unit overall particularly when compared with competitor models of strange or potentially messy maintenance no one wants for sure. We dug a big hole and filled with compost from toilet for our lovely maple tree (not edible and ornamental) and it is doing great. Thank you for a great product.
