Prasad Kaparaju
Griffith University, Australia

 

Biography: Professor Prasad Kaparaju is an internationally recognised leader in environmental engineering, waste management, waste-to-energy technologies, and the circular bioeconomy, with over 24 years of research, innovation, and industry engagement in sustainable bioenergy systems. His research focuses on biomass-to-biofuel conversion technologies, renewable energy systems, anaerobic digestion, and integrated biorefineries, with the goal of transforming organic wastes and biomass resources into renewable fuels, chemicals, and value-added bioproducts.
Professor Kaparaju has successfully led 26 competitive research projects as Chief Investigator, supported by major national and international funding agencies including the CRC for Renewable Energy and Low Carbon Technologies (RACE for 2030), Australian Renewable Energy Agency (ARENA), Department of Industry, Innovation and Science, Australia’s Economic Accelerator Launch Program, Sustainability Victoria, Business, Research, Industry and Innovation Grants, the Ian Potter Foundation, KONEKSI grants, and the Department of Foreign Affairs and Trade (DFAT), Government of Australia. Since 2014, he has secured approximately AUD $6.99 million in research funding from federal and state governments, industry partners, and consultancy projects.
Professor Kaparaju is widely recognised for pioneering work in biogas and biomethane technologies in Europe and Australia. He was the first researcher to demonstrate the production of biogas and its upgrading to Bio-CNG for use as a vehicle fuel in Australia, establishing an important pathway for renewable transport fuels. He was also among the early researchers globally to develop integrated biorefinery concepts based on lignocellulosic biomass such as wheat straw, which later influenced the development of waste biorefineries and other lignocellulosic biomass conversion platforms.
His research spans anaerobic digestion for waste and wastewater treatment, biohydrogen, biogas and bioethanol production from organic wastes, biomass pre-treatment technologies, nutrient and energy recovery from industrial and agricultural wastes, biomethanation, Bio-CO₂ utilisation, and the production of biofertilisers and platform chemicals within circular bioeconomy systems. He also has extensive experience in process design, techno-economic assessment, and feasibility studies for waste-to-energy infrastructure, particularly industrial biogas plants.
Professor Kaparaju is also an experienced educator and international trainer, delivering specialised workshops and capacity-building programs in renewable energy systems, sustainable energy technologies, and biogas engineering. He has trained waste management professionals and government officials from Indonesia, Singapore, Vietnam, and Mongolia, contributing to international knowledge transfer in sustainable waste management and bioenergy systems.
His research output includes more than 170 peer-reviewed journal publications, 15 book chapters, and over 20 conference publications. His work has received 8,147 citations, with an average of approximately 237 citations per year and 48 citations per publication (2026). His h-index is 38 (Web of Science) and 41 (Google Scholar).
Professor Kaparaju has also been recognised as a Top 2% Scientist globally in the Stanford University ranking (2021–2022) in the fields of Energy, Biotechnology, and Enabling & Strategic Technologies, reflecting the international impact and influence of his research.
