Development of a tiered duckweed cultivation system

9 Jan 2024

A new paper has been published on the development of a stacked duckweed cultivation system:

Coughlan, N. E., et al. (2023). On the rise: Development of a multi-tiered, indoor duckweed cultivation system. Water Environment Research, 95(12), e10964.


The paper describes the development and operation of a multi-tiered duckweed bioreactor.


Duckweed species (Lemnaceae) are suitable for remediation and valorization of agri-feed industry wastewaters and therefore can contribute to a more sustainable, circular economy where waste is a resource. Industrial applications will, however, require space efficient cultivation methods that are not affected by prevailing weather conditions.

It is envisaged that multi-tiered, indoor bioreactors can be employed in the agri-feed industry where wastewaters are, in many cases, continuously generated throughout the year and need remediating immediately to avoid costly storage.
