Lignosize, a renewable hydrophobing agent

Important results from the project

The project Lignosize has demonstrated a completely new value chain from kraft lignin to a renewable chemical in paper production. The renewable chemical can replace a fossil chemical and thereby reduce the fossil carbon footprint of papermaking. The properties of the renewable chemical have very good properties and even outperform the fossil chemical in long-term studies.

Expected long term effects

Cooperation between different branches of industry is a way of working that brings new thinking and can contribute to creating new value chains and for transformation of the industry. Successful examples also contribute to more collaborations being initiated and potentially new products reaching the market. An important long-term effect is to strengthen and establish new cooperation between the chemical- and forest industry, which has a great potential for leading the transition of the industry.

Approach and implementation

The project has been carried out: From initial trials on a laboratory scale to demonstration of the manufacturing process as well as full-scale evaluation on a paper machine. In all parts as described in proposal. Increased costs that could not be foreseen have delayed the project. The project parties have lined up in a fantastic way with resources to solve problems that have arisen. The timetable has been adjusted in a valued and constructive agreement with Vinnova.
