Present situation and development trend of eco-utilization of residue production in plant extraction

In this paper,the eco-utilization of residue from plant extraction is discussed,the current situation and development trend of residue treatment are introduced with emphasis on it.The technology of biomass briquetting and pyrolysis without oxygen for the treatment of residue production in plant extraction is proposed,by which the residue is transformed into the product such as bio-char,bio-oil,biomass vinegar,biomass gas and so on.And the economic value and practical significance of this method is also expounded.
