Duckweeds are small, prolific plants abundant as weeds in freshwaters which can be a source of biomass for bioenergy production. It has approximately 40 species worldwide, classified into five genera: Spirodela, Lemna, Wolfiella, Wolffia and Landoltia. Due to its structural and chemical characteristics, duckweed is a promising feedstock for biomass-based energy production.
Duckweeds' high content of valuable fatty acids and starch could be useful in biorefineries. Recent laboratory studies have also shown remarkable results in terms of energy yield during anaerobic digestion, incineration, pyrolysis, gasification, and oxidation.
Duckweeds also possess hyperaccumulative properties for a variety of water pollutants and are therefore recommended in on-site phytoremediation systems for community wastewater treatment. Hence, adapting duckweed can help the environment through wastewater treatment as well as energy biomass production for sustainable development.
