Biofuel production from starchy crops: advanced technology and current perspectives

Area of Science:

• Biotechnology
• Sustainable Energy
• Agricultural Science

Background:

• Growing demand for sustainable alternatives to fossil fuels.
• Starchy crops (wheat, barley, cassava, potato, maize) are key feedstocks for bioethanol.
• Need for efficient and environmentally friendly bioethanol production processes.

Purpose of the Study:

• To review current perspectives and advanced technologies in bioethanol production from starchy crops.
