The spent coffee and tea grounds, which are typically disposed to landfills, will be used as raw materials for development of functional materials by using chemical processes, such as extraction and pyrolytic processes. The derived products will be characterized by the high performance liquid chromatography to see the distribution of the extracted products. After the extraction, the residues of both coffee and tea grounds will be undergone the "inert pyrolysis" and the expected carbonaceous materials will be further functionalized and can be used as selective adsorbents for the application of environmental control.
Applicants will be responsible for the experimental, characterization, and data interpretation.
(1) To understand the fundamentals of how to apply the appropriate chemical processes for converting the "real"solid waste into useful products.
(2) To earn the solid experience in doing experiments as well as the characterization
(3) To learn how to conduct the academic research and apply it for the society
