| Abstract | Duckweed (Lemnaceae) is a hardy plant with prolific growth that is being investigated not only as a water purifying agent, but also as a source of protein. It needs rich sources of potassium, phosphorus and nitrogen to grow--all elements found in human and animal waste. In Bangladesh, it is used as a cheap and high quality animal feed, and Israelis are selling it to European health stores as a gourmet salad. The effluent of 100 people is sufficient to fertilize a quarter-hectare plot, which is a manageable size for a single farmer. The duckweed must be harvested before decomposing or it loses its economic value. A duckweed-based wastewater treatment plant is planned in Bangladesh by Lemna Corporation. Duckweed has also been shown to increase fish production, especially carp, a Bangladeshi staple. |
