Abstract

The invention refers to a process for manufacturing paper or paperboard from a pulp containing fibres, and where the process includes a stage for eliminating or reducing micro-organisms such as bacteria and/or spores, and where said first part passes a process phase where it is treated with steam so that it reaches a temperature exceeding 900C, whereupon the treated first part is subsequently mixed with a second part of the pulp and the mixed pulp is drained on a wire to form a fibre web. The invention also refers to a paper or paperboard product that has been manufactured according to the process.
