Renewably powered aeroponic farms beat imports

The life cycle analysis was published in the journal Science of The Total Environment by researchers from Brunel University London and LettUs Grow. 

The paper explores the environmental credentials of aeroponic container farms and their potential role in sustainable food systems. Aeroponic container farms are a new method of farming that use a soilless technique to grow crops in a controlled environment. This method involves suspending the plant roots in a nutrient-rich mist, which helps to optimise crop growth and reduce water usage.

The study examines the environmental impacts of an aeroponic farm container system in the UK, across a full set of 19 sustainability indicators. It found that aeroponic container farms show competitive performance against conventional methods. The results of the study are significant, as they demonstrate that aeroponic container farms could offer lower impact food when compared with imports. This could also improve food security in terms of availability, stability, and access to food.  

“This is one of the first studies of its kind. It evaluates aeroponic vertical farming’s environmental credentials under real world scenarios. As with any agricultural technology innovation, container farms are best placed to benefit the environment in specific use cases, locations or for specific crops. This research is integral for allowing us to make educated decisions about where and how an aeroponic container farm should be used to create a positive impact.” said Jack Farmer, study co-author and Chief Scientific Officer at LettUs Grow.
