Research Focus

Assoc. Prof. Dr. Pawinee Chaiprasert, with an expertise of biotechnology along with food technology, has been leading the multi-disciplinary team of researchers/lecturers working on biogas technology research and development since 1996.  Dr. Pawinee and her research group, called “Biogas Laboratory” then, changed the name to “Excellent Center of Waste Utilization and Management (ECoWaste) in 2006, passionately focus their research theme on the R&D of a high-rate biogas technology named “Anaerobic Fixed Film Reactor: AFFR”.  The AFFR technology, the Center’s first generation technology, is suitable for various agro-industrial wastes and wastewaters, such as tapioca starch, rice starch, palm oil, food processing wastewaters, with its advantages of high system stability and excellent treatment efficiency. Dr. Pawinee directs ECoWaste to excel in four key research areas: (i) microbiological and biochemical aspect, (ii) reactor and process development,   (iii) computational aids and process optimization, and (iv) environmental research and management.  Research has been conducted in lab-scale, pilot-scale, and industrial-scale levels. The AFFR-technology-transferred factories benefit directly from their generated biogas for heat and electricity generation. Dr. Pawinee is currently a senior advisor to the ECoWaste with her role to guide and mentor this multi-disciplinary team as well as to develop the group’s second generation biogas technology, the Anaerobic Hybrid Reactor (AHR) to answer the country’s agro-industrial environmental and energy needs.
