Application

• The project has applications in enhancing bioethanol production from water hyacinth, improving cost-effectiveness, and providing a sustainable biomass source for biofuel, while also addressing environmental issues.

Description

Indian researchers from the Indian Institute of Technology Kharagpur (IITK) have developed a novel method to extract bioethanol from water hyacinth, an invasive plant rich in hemicellulose. By focusing on pore-scale phenomena, the team discovered that increasing the porosity and swelling of hemicellulose can significantly enhance the release of fermentable sugars, boosting bioethanol production. This breakthrough suggests that combining cellulosic and hemicellulosic ethanol from the same biomass could increase biofuel yield and energy efficiency by over 50%, making it a promising and cost-effective approach for biofuel production.

Pathway Description:

The process used in the project involves increasing the porosity and swelling of hemicellulose in water hyacinth to enhance the release of fermentable sugars. By focusing on pore-scale phenomena, the researchers improved the efficiency of converting both cellulose and hemicellulose into bioethanol. This approach boosts the yield of biofuel by utilizing both components of the plant, making the process more cost-effective and productive.
