I'm part of the new world-skills water innovation challenge. I'm not going to the competition, I'm just in the pit team helping to design the system.
One of the things I did was have a meeting with an RMIT researcher (Aidyn Mouradov) on phytoremediation, which is an interesting topic.
Anyway, heres two open access papers on the topic, specifically Duckweed and Azolla. Both are incredibly fast growing and versatile plants (compost, high protein livestock feed, fuel source, water purifiers, feed for bioplastic, etc)
Application of Aquatic Plants for the Treatment of Selenium-Rich Mining Wastewater and Production of Renewable Fuels and Petrochemicals
Dual application of duckweed and azolla plants for wastewater treatment and renewable fuels and petrochemicals production
