Since obtaining her PhD in ‘Valorisation of Lignocellulosics by oxidation’ from Université de Poitiers, and following a Postdoc position working on ‘Wood chemistry and analyses’ at Abo Akademi in Finland, Dr Frédérique BERTAUD has been a scientist at CTP (Centre Technique du Papier in Grenoble) for over 18 years. She specialises in the field of wood and pulp chemistry, particularly the ‘Development of Biorefinery applied to pulp mills’. More specifically, she is responsible for the valorisation of pulp mill by-products, such as wood extractives and lignin, covering their extraction from lab to semi-pilot scale, and their analyses. In connection with pulp mills, she has developed modelling tools to simulate extraction units in an existing pulp line, and establish the technical and economic impacts of such valorisation.
Integration of a lignin production unit in an existing pulp mill: technical and economic conditions for an efficient biorefinery
Lignins are aromatic natural polymers which, along with cellulose and hemicelluloses, compose the cell walls of wood. During chemical pulping, lignins are partially degraded and solubilised in cooking liquor. Currently, lignins in black liquor are generally burned in order to contribute to a mill’s self-sufficiency in energy. At present, only 1 million tonnes of lignin are available in the world per year, the main source coming from the acid sulphite process that leads to lignosulfonates. The pulp and paper industry, with 183.8 million tonnes of pulp produced worldwide, is a good potential source of 50 to 70 million tonnes of lignins. Within the framework of the development of bio-sourced products made from renewable raw materials, lignins are interesting ‘green’ alternatives for the production of aromatic and carbon products. The global lignin market is expected to significantly expand with the recent and forthcoming creation of new production lines combined with new valorisation routes. This study aims to establish the technical and economic impacts of lignin extraction in existing pulp mills through the development of modelling tools based on industrial and experimental data.
