废弃烟草资源化利用研究进展

我国是烟草生产大国,每年相应产生大量废弃烟草。通过萃取法可从废弃烟叶中提取烟碱,提取的烟碱具有杀虫及治疗疾病的功效;烟梗、烟末废料经粉碎加工之后可制成烟草薄片;废弃烟杆经炭化活化后能制成活性炭,还可制成纤维板等;废弃烟草经生物技术处理后可制得乙醇和有机肥等。本文结合国内外相关研究资料,对废弃烟草的利用进行了综述及展望。

Research Prongress on Resource Utilization of Tobacco Waste

China is a major country of tobacco planting, however, there are large quantities of tobacco waste which are produced annually. Nicotine can be obtained from tobacco leaves with the process of extraction, and the nicotine can kill insects and acts as curative powers. Tobacco caulis and smalls can be made into tobacco slice by milling and reprocessing. Tobacco stems can be made into not only activated carbon by the process of carbonization and activation, but also fiberboards. They can also be used for making ethanol and fertilizer by the fermentation process. The paper reviews the utilization of tobacco waste based on the information at home and abroad, and looks ahead to the prospect of its utilization.
