Dual application of duckweed and Azolla plants for wastewater treatment and renewable fuels and petrochemicals production

"In this paper, the feasibility of the dual application of duckweed and azolla aquatic plants for wastewater treatment and production of renewable fuels and petrochemicals is explored. The differences in absorption rates of the key wastewater nutrients, ammonium and phosphorus by these aquatic macrophytes were used as the basis for optimization of the composition of wastewater effluents. Analysis of pyrolysis products showed that azolla and algae produce a similar range of bio-oils that contain a large spectrum of petrochemicals including straight-chain C10-C21 alkanes, which can be directly used as diesel fuel supplement, or a glycerin-free component of biodiesel. Pyrolysis of duckweed produces a different range of bio-oil components that can potentially be used for the production of “green” gasoline and diesel fuel using existing techniques, such as catalytic hydrodeoxygenation."

Azolla Genome's insight:

Cleanup wastewater and produce biofuels at the same time? Yes, Azolla can do it!

The Arctic Azolla event

"This flexibility is the key to Azolla’s global potential. The complex biotechnology has already been developed by Azolla and A. azollae’s co-evolution, so all we need to do is work with nature instead of destroying it. And because Azolla’s biosystem addresses the problems of energy and food as well as climate change, it is not necessary to prioritise them. This resolves the main problem that plagued the 2009 and 2013 Copenhagen and Doha Summits on Climate Change when many developing countries argued that their priority was to feed their people, rather than dealing with problems of climate change. The billions of pledged ‘climate change dollars’ can therefore help developing countries using Azolla’s synergy, thus turning Perfect Storm into Perfect Opportunity. Geologists are fortunate in having a unique perspective grounded in deep-time. We have traditionally used the present as a key to the past, but we can also use the past to understand the present and shape the future in a positive way. Perhaps the remarkable events that occurred 49 million years ago in the Arctic can help us do that."

Phytodegradation potential of BPA from aqueous solution by Azolla filiculoides

"The results indicated that Azolla has high ability to remove BPA from aqueous solutions. The BPA removal was 60-90%. The removal efficiency is increasing with decreasing of BPA concentration and increasing of biomass amount and vice versa. The removal efficiency was more than 90% when BPA concentration was 5 ppm and amount of biomass was 0.9gr. It is concluded that Azolla able remove BPA by Phytodegradation from the aqueous solutions. Since conventional methods of BPA removal need to high cost and energy, phytoremediation by Azolla as a natural treatment system can decrease those issues and it can be a useful and beneficial method to removal of BPA."

Guest commentary: Offering an ancient solution to a modern problem

"Fifty million years ago, the Earth was so warm that turtles and alligators thrived in lush forests at the poles. Much of the North Pole was covered in a rather less charismatic life form: the floating, duckweed-like fern Azolla..."
