Recycled fertiliser from dry toilets - can it work?

Isn't something like that unhealthy or unhygienic? No, it's not!

And yes, it works!

A lot of good can be achieved with recycled fertilisers from dry toilets - we can save water, recycle nitrogen and phosphorus.

In short, it's the most natural cycle in the world!

After all, it is not the fertiliser that is eaten, but the vegetables that are supplied with important nutrients and grow magnificently as a result.

Under the following link, our colleagues in the "Sendung mit der Maus" explain exactly what is behind it, why it makes sense to use dry toilets and how they work.
