Biorefining of bark in biochemical conversion and in forest-industrial processes
Bark is an underutilized residual stream from pulp and saw mills and its utilization in biochemical conversion is not well investigated.
In this project, the technical and economic potential of separate biorefining of fresh bark through innovative pre-processing technology and green extraction has been examined. The project covers the predominant bark varieties in Sweden, i.e., bark from spruce, pine and birch.
Better use of bark has potential to provide more liquid biofuel without increased withdrawal of forest resources, new products, and improved biochemical conversion.
