On May 24, the annual award ceremony for the Heinzel-Mondi-Sappi Award 2023 was held at the Paper and Biorefinery 2023 conference in Graz. Dr. Claudia Esteves was awarded in the Pulping Process category, prize giver Kurt Maier, Heinzel Group. Heinzel Group stands for the Pulping Process category, Mondi Group stands for the Resource Efficiency category and Sappi gives the award in the Paper- and Board Making Process.
In the Resource Efficiency Martin Nigl was awarded and in the Paper- and Board Making Process Hamid Ahadian was awarded.
Dr Claudia Esteves works as a researcher at RISE and received her dissertation on December 16 and her thesis is entitled "Increased pulp strength through oxygen delignification". The opponent was Professor Christine Chirat, Grenoble INP – Pagora, UGA and the supervisors Elisabet Brännvall, Olena Sevastyanova and Sören Östlund.
From abstract: “Oxygen delignification is widely used in the pulp and paper industry as a part of delignification process between the kraft cook and bleaching. However, its potential has not been fully utilized. Rather than an intermediate process between cooking and bleaching, oxygen delignification is a strong oxidizing agent with powerful effects on the pulp properties, the hypothesis that oxygen delignification has the potential to improve the pulp mechanical properties was investigated.”
