    The TROBOLO Separator: The heart of your separating toilet

    A separating insert is the heart of every composting toilet, because it ensures separation of solid and liquid waste. Years of experience and testing have enabled us to develop a separator that is designed not only to achieve complete separation of urine and faeces (excrement), but also to offer the highest level of comfort, flexibility and hygiene beyond its separation mechanism.

    Using a composting toilet with the TROBOLO separator works just like a conventional toilet. Inside the toilet, however, urine and faeces are separated. The urine is collected in the front area and is discharged into a separate liquids container, an external container outside the toilet or separately into the sewerage system via a pipe. Faeces, on the other hand, go into a solids container in the rear part of the separator. The separator is designed to meet the different anatomical requirements of all toilet users, while always ensuring clean and reliable separation of faeces.

    The TROBOLO Insert for Urine-Diverting Toilets is particularly suitable for building your own composting toilet and allows you to implement your individual wishes and needs. Especially practical is the fact that the separator can be used with any standard toilet seat, which greatly simplifies the planning of your self-built separating toilet and the associated procurement of materials. In addition, the innovative TROBOLO adapter system offers you the possibility of attaching a hose which can drain urine externally and can be connected to the grey water tank of your motorhome, for example. The hose can easily be attached to the new adapter system with integrated filter screen, which makes installation particularly easy and also allows you to remove the hose if necessary to clean or replace the filter screen. All TROBOLO composting toilets, which you can purchase as a complete solution in our online shop, also use this separating insert. This means that it can also be purchased as a spare part if you already own a TROBOLO composting toilet.

    Faeces pass completely contact-free through the rear part of the TROBOLO separator into the solids container equipped with inlays, making subsequent emptying very easy. The inlays can be removed and disposed of or composted in no time at all. The deep-drawn collar of the rear opening of the separator also reliably protects the interior of the toilet from contamination. In addition to the smooth and closed surfaces, a high-quality surface seal guarantees a long service life as well as practical and hygienic cleaning. Ideally, we recommend an environmentally friendly cleaner for this purpose.

    Your advantages of using a separating toilet insert

    Conventional water closets, but also chemical toilets or classic composting toilets all do without the separation of urine and faeces. However, this proves to be problematic when it comes to disposal of waste. Emptying containers that mix solids and liquids is a considerable challenge for you as a user and by no means as uncomplicated and clean as emptying separate solids and liquid containers.

    The separation of urine and faeces also consistently avoids unpleasant odours and water can be dispensed with completely when using the toilet. Due to the simple and uncomplicated disposal via household waste or through composting of the faeces, the use of a separating toilet is completely self-sufficient.

    Do it yourself – with the new TROBOLO Separator

    Our newly developed separating toilet insert is ideal for building your own composting toilet solution. This part allows for perfect separation of solid and liquid materials and is made of responsibly selected, recyclable polypropylene. The selection of this material enables the separator to have a very long service life, which was an important consideration for us in the development of the separator from the point of view of sustainability. Only the filter screen can wear significantly over time due to deposits.Compared to products from other manufacturers, individual parts can be replaced in seconds thanks to the TROBOLO adapter system, while the rest of the insert remains unaffected by wear and can continue to be used.

    The adapter system also allows flexible connection options, so that in addition to collecting the urine in a liquid container, it can also be discharged via a DN 32 hose. Regardless of which connection option you choose, the integrated seal always ensures an absolutely secure connection to the separator.

    Ready to use toilet solutions with the TROBOLO Insert for Urine-Diverting Toilets

    In all our TROBOLO composting toilets the TROBOLO separator is already installed and the individual components are perfectly matched. You will receive our TROBOLO toilets either fully assembled or as prefabricated kits including all accessories and easy-to-understand assembly instructions delivered directly to your home.

    Our TROBOLO composting toilets are all handmade and consist of solid wood and highly durable alder multi-ply wood. Different versions of our composting toilets are available to you:

    If you are looking for a composting toilet for outdoor use, our TROBOLO KersaBœm is the ideal solution. For indoor use, there are various toilet solutions available to suit your personal requirements and needs.

    Our standard models for indoor use are the TROBOLO LuweBlœm and the TROBOLO LeliBlœm. While the TROBOLO LuweBlœm is completely connection-free and can therefore be used independently, the TROBOLO LeliBlœm has an electrical exhaust air system, which makes the use of litter superfluous and yet effectively prevents the formation of odours.

    Of course you can also build a separating toilet for indoor use yourself. The TROBOLO TeraBlœm, which is sent to you as a complete kit with all accessories and the corresponding assembly instructions, is ideal for this purpose. But even if you would like to build a composting toilet yourself without any kit, you can still use the TROBOLO separating insert. You can find out how it works here.
