Bioethanol production from batch and continuous phytoremediation systems

The effectiveness of water hyacinth (Eichhornia crassipes) in remediating municipal wastewater and producing bioethanol in batch and continuous systems was compared with water lettuce (Pistia stratiotes) and water spinach (Ipomoea aquatica). Batch experiment was conducted using stagnant wastewater s...
