A photobioreactor for production of algae biomass from gaseous emissions of an animal house.

ABSTRACT: Sustainable approaches to circular economy in animal agriculture are still poorly developed. Here, we report an approach to reduce gaseous emissions of CO₂ and NH₃ from animal housing while simultaneously using them to produce value-added biomass. To this end, a cone-shaped, helical photobioreactor was developed that can be integrated into animal housing by being freely suspended, thereby combining a small footprint with a physically robust design. The photobioreactor was coupled with the exhaust air of a chicken house to allow continuous cultivation of a mixed culture of Arthrospira spec. (Spirulina). Continuous quantification of CO₂ and NH₃ concentration showed that the coupled algae reactor effectively purifies the exhaust air from the chicken
