Our history

At Sonnenerde, we don't build cars, we don't construct roof trusses, and we don't serve cocktails. We work with something completely different: the breeding ground for a life that lies in the present, but also in the near and distant future.

With evolution and with the Earth, where it continues to take place. And with the resources of this Earth, which are not unlimited. So we have begun to create our own resource: Sonnenerde. Humanity now knows that it can intervene in nature and that each of us has a say in what the world around us will look like tomorrow. We at Sonnenerde

think this is great and have accepted the responsibility to treat the environment with respect. Ultimately, every gram of Sonnenerde is the result of dedicated employees who want to live in harmony with a healthy natural environment. With our attitude to our work and our products, we make a contribution that everyone who thinks similarly to us at Sonnenerde should be able to afford.

We produce 
healthy soils



Simply disposing of biomass is not enough for us! After 13 years of consulting, I have come to realise that most composting plants are not interested in producing high-quality compost (or even finished soil), but only in disposing of waste. The separate collection of organic waste triggered a composting boom that greatly damaged the image of compost. Composts were offered on the market that really did not deserve the name ‘compost’ – black, charred, foul-smelling, but finely sieved masses were not only sold, but also used to the detriment of plants.

Frustrated by these facts, I decided to leave consulting and set up my own compost and soil plant. The aim of this plant is to produce the best possible compost quality and, as a result, the best possible finished soil.

Today, we claim that our products are not only visually appealing, pleasant-smelling, easy to use and ecologically valuable, but also that our products optimise the plant location for many years, thus ensuring optimal plant growth. Professional users such as garden designers expect not only professional quality, but also that this material is available and deliverable at a consistently high quality. We are now able to meet this requirement too! Compliance with all standards and guidelines is a matter of course for us! In particular, the following regulations are observed:

  • Composting Ordinance
  • ÖNORM B 2606-1: Sports field receipts, lawn receipts
  • ÖNORM S 2203: Requirements for cultivated soil from compost
  • ONRegel 121131: Quality assurance in green roofs – roof substrates
  • FLL-Richtlinie: green roof guideline

CO2 is only produced during combustion

Composting binds carbon in the form of humus instead of releasing it. In this way, Sonnenerde reduces the burden on our planet's atmosphere.

Sonnenerde makes frogs happier

The careful production of high-quality ready-made soil largely replaces most peat products. This preserves many valuable wetland biotopes for our ecosystem.

Nature as fuel

In 2013, a 150 kWp photovoltaic system was installed on the roofs of our halls. Step by step, the technology and vehicle fleet are being converted to electricity as far as possible.
