The sky farm, or vertical farming, will not only provide the town’s residents with fresh vegetables, the scientists are also developing greenhouses for astronauts in space. As part of their research to build the greenhouses, engineers from DLR have already grown dozens of lettuces under a pink light in a sterilized laboratory. The greenhouses contain combined life-support systems and do not require soil, but hang in the air whilst their roots are constantly sprayed with a solution containing nutrients.

And now, researchers from a wastewater treatment plant in Rotenburg an der Fulda have shown that algae can also clean waste water. The cleaning abilities of algae were demonstrated during the Hessian pilot project “phosphorus removal by microalgae”. The research project has been funded by the Hessian Ministry for the Environment, Climate Change, Agriculture and Consumer Protection together with the public utilities of Rotenburg since 2015 over a two-year period with a total of €620,000.
