Urban Algae Farm Gobbles Up Highway Air Pollution


A French and Dutch design firm has come up with an elegantly simple way to harness the wonderful power of nature in order to clean up the environment: an algae farm suspended over a small stretch of highway in Geneva, Switzerland.

Algae are a diverse group of organisms that, like plants, generate energy from photosynthesis using sunlight and carbon dioxide, churning out oxygen along the way. Since CO2 is a pollutant that’s produced by car engines, a busy highway riddled with environmentally damaging emissions is the perfect place to set up an urban algae farm.

The bioreactor consists of a closed system of transparent, algae-filled tubes that are hooked up to secondary equipment such as filters, pumps and solar panels. Thriving on the abundance of CO2 and sunlight, the algae will bloom and mature inside the tubes, filtering the air before being extracted and used for a variety of applications. According to the company that came up with the idea, Cloud Collective, the material could be used to create biodiesel, green electricity, medication, cosmetic products or even foods. That’s quite an impressive list.

The functioning and the placement of this bioreactor signal practices of the future: food production in an urban environment, the conservation of green space and the reinterpretation of existing infrastructures,” the Cloud Collective writes on their website.

At the moment, the bioreactor is a proof of concept system that was built as part of a garden festival in Geneva, which “focuses on the co-habitation of the urban and the natural within the context of the urban expansion of Geneva.” However, it demonstrates how easy it could be to scale-up and install over larger areas.

  1. Vanessa Restrepo Schild jóven investigadora paisa en el area de biotecnología comparte este interesante uso de las algas para purificar el aire
    en zonas urbanas. De las algas también se puede producir Espirulina, que es un alimento lleno de nutrientes importante para el desarrollo infantil. Se podría utilizar en areas donde hay alto indice de desnutrición como Chocó y Guajira, Colombia.
