SETRENLO® separator insert for composting toilets – sustainable, functional

📦 Delivery time: Delivery from March 2026


 The SETRENLO® separator insert is the central component for high-quality composting toilets – ideal for DIY projects, upgrades, or as a replacement part. Designed for daily use, it enables reliable and comfortable separation of urine and solids, without any need for adjustment.


 Made from DUROLEN®, an impact-resistant and durable thermoformable plastic with excellent recyclability (monomaterial), the separating insert is dimensionally stable, hygienic, and easy to clean. The smooth, light-colored surface is visually unobtrusive and blends harmoniously into modern composting toilet designs. The ergonomic shape ensures clean and practical everyday use – handling feels just like a conventional toilet.


 Thanks to its well-designed geometry, everything stays where it belongs. Combined with ventilation and a urine tank, unpleasant odors are a thing of the past.


 The separator insert can be flexibly connected: for an integrated urine tank as well as for external tanks. Suitable connectors are available separately – so your system adapts to your installation space and your requirements.


 A functional, durable component without compromise – for all those who want to build their composting toilet in a high-quality and well-thought-out manner.
