Recycled Fertiliser Aurin

No shit? Aurin is the first urine fertiliser in the world with full approval from the swiss authorities. The best solution for your vegetables & flowers.

Aurin - The first urine fertiliser worldwide with full approval. Aurin is a universal fertiliser made from human urine. VunaNexus offers the process that converts urine into fertiliser. In the process, drug residues, hormones and germs are removed, but the nutrients remain in the urine.

Pure recycling

Aurin closes cycles. Do you recycle glass bottles, aluminum cans, newspaper? From now on also urine! Because you produce whopping 500 L of it per year. The nutrients in it are valuable and do not belong into the sewer.

Globally local

The ingredient for Aurin is very local – all over the world: human urine. Thanks to Aurin, there are no fertilizer imports with long transports and a lot of energy consumption.

Without heavy metals

Aurin is concentrated – lots of nutrients but no heavy metals, such as in conventional phosphorus fertilizers. You protect the environment and yourself.

Without medication

The Vuna process ensures that all pollutants are eliminated. Aurin concentrates what is naturally in the urine: nutrients for your plants.

Economical with water and waste water

For Aurin, urine is processed directly without dilution and no longer needs water to move down the sewer system. Thus, it is more efficient than any sewage treatment plant.

Officially approved by the Federal Office

Officially approved as a fertilizer by the Federal Office for Agriculture (→Product register). After an intensive test phase starting in 2015, Aurin received definitive approval in 2018.
