What’s the source of nitrogen in Solein?

The source of nitrogen for Solein is ammonia (NH3) as an ammonium (NH4+) water solution in the growth medium. Solein factories have been planned to include their own green ammonia production through the Haber-Bosch synthesis. If ammonia production is not done locally, green ammonia is sourced from the market.

For the time being, the figures reported for Solein’s environmental impact assume the use of ammonia produced with natural gas. About 20% of the remaining climate impact reported for Solein production is due to the use of ammonia.
