| dc.description.abstract | The purpose of this research has been to design a lignin sensor fornon-destructive, real-time identification of waste paper grades, toaid in automating a waste paper sorting process. The sensor iscapable of identifying about 500 papers in one second. It is based onthe principle that fluorescence light emitted from paper followingabsorption of visible light has a wavelength distribution determinedby the chemical composition of the paper. The sensor is the most critical part in waste paper sorting, whichhas hitherto not been automated due to the inability to design asensor that distinguishes paper grades. This sensor is vastlysuperior to all other sensors previously designed for this purposebecause, it does not use the conventional reflective type opticalproperties of paper, and this is the only sensor that can identify all grades unlike the previous sensors that could identify only whiteledger papers. | en_US |
