Roberto M. Malaluan

Outstanding Young Science (2000)

Expertise: Extraction and Refining of Bioactive Substances from Marine Sponges Using Supercritical CO2, Extraction and Refining of High Value Chemicals from Plants Using Supercritical CO2, Extraction of Pollutants from Soil and Wastewater Using Supercritical CO2, Hazardous Waste Detoxification Using Supercritical Water Oxidation, Enzymatic Reactions in Supercritical CO2, Recycling of Industrial Wastes and Plastics, Wastewater Treatment, Watershed Planning and Protection

Dr. Roberto Malaluan is recognized for his pioneering work on rapid hydrolysis of cellulose in supercritical water to recover high value of chemicals. His method of converting glucose by reaction with supercritical water to erythrose in as high as 50 wt% has an advantage over other conventional methods and results in comparatively high yield of erythrose. His work on alternative process for extraction of oil by superficial CO2 is considered to overcome negative aspects of the traditional techniques and have a great potential to be commercialized.
