Review of evolution, technology and sustainability assessments of biofuel production

Biofuel is recognised as an important renewable and sustainable energy source to substitute fossil fuel. To date, biofuel has been evolved from first to fourth generation and they are mainly differed in feedstock and production technologies. Along with the evolution, various studies on different sustainability criteria have been conducted. In this review paper, the state of the art of technologies and assessment methods on economic performance, safety, health and environment (SHE) as well as social impact for biofuel production are reviewed. In addition, this review paper also evaluates the typical methodological framework used for systematic assessment during early process design phase. As conclusion, to establish the highest sustainability in biofuel production, continuous research and development on all sustainability-related aspects are very much needed.
