Quality urine diverters out of conviction

So that you can use your composting toilet with a clear conscience, we use environmentally friendly and durable materials in the manufacture of our products. We only use responsibly cultivated wood for our wooden products.

Our composting toilet inserts are made of durable plastic that is 100% recyclable. Separating the excreta eliminates the need for chemicals and water, thus protecting the environment. Electricity is only needed to a small extent, if at all, namely when an electric exhaust system is used.

Those who decide to compost the solid excreta and use the liquid excreta as natural fertiliser are acting in a particularly sustainable manner. Alternatively, the solid waste, like used diapers, can be disposed of in the household waste and the liquid container emptied in a regular toilet.

Don’t feel like building your own? Here you can find our prefabricated composting toilets as an alternative.
