The possibility of aquatic weeds serving as a source of feedstock for bioethanol production: a review

Anaerobic digestion is recognized as an attractive option for the effective management and treatment of lignocellulosic biomass as well as waste recovery of resources for bioethanol production. Long enough testing has been done on bioethanol production using lignocellulosic biomass. This helps to reduce stress and global energy problems. Global wide has a variety of environmental impacts due to its use of fossil fuels. Bioethanol might be produced in Asian locations from many types of biomasses, including agricultural waste, forest waste, and wood biomass. This would be an environmentally friendly process. Unfortunately, there is very little research into the production of ethanol from rice field weeds. This makes it difficult to develop bioethanol production. This review is aimed at developing bioethanol production and the trend towards organic products that began nowadays. Unwanted weed growth is a major problem in rice cultivation. This review demonstrated the waste-to-energy aspect of the bioethanol production process using two weeds, gooseweed (Sphenoclea Zeylanica), and small-flowered nutsedge (Cyperus difformis).
