David Kabutey Akuaku Advances Waste-to-Resource Research for Clean Energy and Healthier Soils

David Kabutey Akuaku is a graduating PhD candidate in Bioengineering from the Agricultural and Biosystems Engineering Department at Kwame Nkrumah University of Science and Technology (KNUST) and a KNUST Engineering Education Project (KEEP) scholar. His research interests include biomass valorization, biochar production, renewable energy, sustainable waste management, and soil improvement.

His PhD research focuses on valorizing cocoa husk by converting it into biochar and bio-oil, producing enriched organic fertilizer through composting, and evaluating its effects on soil amendment and crop productivity. His work promotes agricultural waste utilization, improves soil fertility, supports clean energy production, and reduces reliance on inorganic fertilizers. By transforming agricultural waste into valuable resources, his research advances the concept of “waste as wealth” and highlights the importance of recycling and resource recovery in promoting environmental sustainability, a circular economy, and a healthier society.

The KNUST Engineering Education Project (KEEP) has played a significant role in his academic achievements by providing essential financial support. David is deeply grateful to the management and staff of KEEP for their invaluable assistance, encouragement, and continued support throughout his academic journey.

He also gratefully acknowledges his PhD supervisors, Prof. Francis Kemausuor, Dr. Kodwo Miezah, and Dr. Shadrack Kwadwo Amponsah, for their guidance, encouragement, and invaluable academic support throughout his research.

David aspires to advance research in biomass valorization, renewable energy, sustainable agriculture, and innovative waste-to-resource technologies
