Dispose of urine – safely, hygienically and environmentally friendly

Urine is not waste, but a valuable resource. It consists of 90–95% water and contains many nutrients such as nitrogen, phosphorus, and potassium.
But what happens after using the toilet – what do you do with the urine from the composting toilet?
Here we show four safe and sensible ways to dispose of waste in an environmentally friendly way.

1. Disposal via the sewer or toilet

The easiest way: pour urine down the toilet or drain.
The sewage system is designed to handle urine, and treatment plants can easily process it.
This method is particularly suitable for everyday use, travel or in urban areas.

2. Disposal at camping disposal stations

Almost every campsite with infrastructure has special disposal stations for grey water.
Urine from composting toilets may also be disposed of there.
Pay attention to the signs or ask the site staff if in doubt.
Tip: Using a small pouring sieve or funnel, the canister can be emptied cleanly and without splashing.

3. Diluted as liquid fertilizer in the garden

Urine contains valuable plant nutrients and, when used correctly, is suitable as a natural liquid fertilizer.
To do this, dilute it with water in a ratio of 1:10 and pour it directly into the root area, preferably in the morning or evening.
Ideal for fruit trees, vegetable patches, flowers and hedges.
Important: Use only if you are not taking any medication.

4. Add undiluted to the compost heap (varies regionally)

In some regions, urine may be added directly to the compost.
It acts as a nitrogen booster and promotes rotting.
However, it should only be used in moderation, as too much urine can lead to odor and imbalance.
Whether this is permitted depends on local regulations – it is best to check with your local council or the waste collection calendar.

When urine should not be released into the environment

If you take medication regularly, urine should generally not be allowed to enter the garden or compost.
Residues can harm plants and soil.
In this case, disposal via the sewer or a disposal station is the best choice.

Conclusion

Urine from the composting toilet can be disposed of safely and effectively in a variety of ways.
Whether via the sewer, at the disposal station or in the garden – the key is correct use and consideration for the environment and health.
