Microalgae production

Operation of an “indoor facility” for the sustainable production of microalgae at the S-chanf site in Engadin / Switzerland.

Project basics

The majority of microalgae are bred in open "outdoor systems". However, these have the disadvantage that entries from the air and water, such as bee pollen, dust, insects, bacteria contaminate the final product.
In contrast to these open investments there are "Indoor plants"which are based on photobioreactors or fermenter systems.
This type of production has only been under construction for 15 years and has the advantage of being able to specifically control all production parameters and the entry of unwanted emissions excluded.

Attempts to obtain artificial fuels and basic animal feed from algae have so far failed due to the high production costs and will therefore presumably not be the basis for commercially meaningful production in the near future.

Thus, an economically sensible production of microalgae is usually about niche products with high added value.

Project idea

Establishment of a "Indoor plant" for the permanent production of microalgae at the Location S-chanf in the Engadine / Switzerland.

The chosen location offers optimal conditions, such as pure water, low energy costs and an authentic environment for a high-quality product.

Impact on the environment / emissions

In production will be no polluting emissions generated. For example, dust, odor or noise from production can be excluded. The complex is located in a closed, windowless building, so no light emissions penetrate to the outside. bigger transport volumes are not connected with this production.


This project lays the foundation for an increasing number of highly-paid and promising jobs in the Engadine and makes a valuable contribution to the local economic structure.
