Algaecultural
Short answer: Microalgae are grown in open ponds or in closed photobioreactors (glass or plastic tubes and panels) that supply light, CO2 and nutrients. The footage is credited to Jongerius ecoduna of Bruck an der Leitha, Austria.
The company says its patented system uses vertical glass modules, moves the culture hydrostatically rather than with pumps, and runs continuously year-round in a 1-hectare plant that opened in 2018. The company's founders originally aimed at biodiesel but concluded algae were too valuable to burn, and the plant targets food, supplements and cosmetics. Algae biofuel is still not commercially competitive: ExxonMobil ended its algae program in 2022-23 after about $350 million.

Video transcript: Algaecultural: Growing Microalgae in Walls of Glass Tubes
DID YOU KNOW? Algae farms can function as large-scale photobioreactors, using sunlight, carbon dioxide, water, and nutrients to cultivate microscopic algae inside transparent tubes, flat panels, or open ponds. Through photosynthesis, the algae rapidly converts carbon dioxide into biomass that can be processed into biofuels, animal feed, nutritional supplements, pharmaceuticals, or industrial chemicals. NOW YOU KNOW!

The write-up
Growing microalgae in walls of glass tubes. Footage from Jongerius ecoduna's photobioreactor plant in Austria.
- Exhibit A
Ponds vs. reactors
Open ponds are the cheapest way to grow algae but are exposed to contamination. Closed photobioreactors, which are tube, panel or bag systems, cost more but give tighter control.
- Exhibit B
The plant in the footage
Jongerius ecoduna says its patented photobioreactor uses vertical glass modules to increase the lit surface, like the leaves of a tree. It moves the algae hydrostatically instead of with pumps and runs 24 hours a day, 365 days a year.
- Exhibit C
From biodiesel to food
Founders Franz Emminger and Martin Mohr started out aiming to make biodiesel but decided algae ingredients were too valuable to burn. The company's 1-hectare industrial plant in Bruck an der Leitha opened in 2018 and produces microalgae for food and supplements.
- Exhibit D
Biofuel reality check
Algae can be processed into fuel, but costs remain high. ExxonMobil ended its algae biofuel program after investing about $350 million, and other oil majors have also pulled funding.
- Exhibit E
What algae are used for
Microalgae are used today for food and supplements, animal and fish feed, pigments and cosmetics. Fuels remain largely in the research stage.
