Duckweed Aquaculture - Potentials, Possibilities and Limitations for Combined Wastewater Treatment and Animal Feed Production in Developing Countries

This literature review provides a first overview of the possibilities, potentials and limits of duckweed aquaculture and its combined use in wastewater treatment and animal feed production in low and middle-income countries. It is somewhat limited as critical literature on duckweed field use is scarce and difficult to obtain (e.g. unpublished internal documents). According to NGOs and commercial suppliers, the duckweed projects seem very positive and promising, and the practical problems encountered with their application rarely mentioned.
