Value added lignins as renewable raw materials dedicated to the end-users requirements out of black liquor of existing pulp mills

Objective

The objective of this project is to develop methods to prepare lignins of controlled grades from black liquors in order to provide the European chemical industry with a new renewable resource at a competing price level of 0.40-1.00 US$/kg which can be adapted to the requirements for different specific end-uses.

In this programme, three types of end-uses for lignin derivatives will be developed, i.e. (bio)polymers and polymer additives, wood adhesives and surfactants. The underlying project is aimed at the valorisation of a present waste stream. By developing of a cost effective method to separate lignin of controlled quality from black liquor and at the same time creating a market for the thus produced new grades of sulfur free lignin, one of the largest environmental problems of (small) pulp mills is solved. Moreover, the European chemical industry is provided by a `new' renewable raw material for a commercial price The integration of partners from the whole production and processing chain, from black liquor suppliers to the chemical industry, makes it possible that lignin grades of specified quality will be developed. The cooperation of two pulp mills from Spain, an engineering firm from Switzerland, German, Swiss and Dutch research institutions and three large chemical industries from Finland and Switzerland, respectively, emphasises the European interest in the project.

The development of several lignin grades for the chemical industry involves the following issues:
1. The improvement and scaling-up of the precipitation of lignin from black liquor;
2. The determination and qualification of the properties of the isolated lignin;
3. The development of end-uses for the lignin raw material.
