Three of the four researchers who will share the 2003 Marcus Wallenberg Prize are women.

Selected for their development of a method that provides a better environment and lower costs for the production of pulp, the winners are doctors of technology Johanna Buchert and Anita Teleman, and professors Maija Tenkanen and Tapani Vuorinen.

They were chosen for their discovery that hexenuronic acid is present in unbleached kraft pulp and for their subsequent development of a method to remove the acid before the pulp is bleached.
