UTILIZATION OF A WOOD HYDROLYSATE |
摘要 |
The present invention relates to a method for utilizing a wood hydrolysate obtained from a hydrothermal treatment of a wood material method comprises the steps of providing a wood material, treating the wood material by means of an aqueous hydrothermal treatment so that a wood hydrolysate and a wood residue is formed. The wood hydrolysate comprises oligo- and polysaccharides as the main component of dry matter. The method further comprises the steps of; separating the wood hydrolysate into at least a first and a second fraction and using at least one of the at least first and second fractions for production of an intermediate or end product. Such end product may be e.g. a film, coating, package or a gel. The present invention also relates to a polymer product such as a film, a coating or a gel and its applications. The present invention provides for biodegradable and renewable polymer products and a method which utilizes and extracts a very high product value from a process.
