Abstract

The invention relates to a method for recycling sulpur in a process for producing paper or paperboard. In the method of the invention, (a) the bisulphite formed from the sulphur recovered in the process cycle is converted to bisulphate by means of an oxidant, the bisulphate being further used as a recycled acid in different process steps, and/or (b) the bisulphite formed from sulphur recovered from the process cycle is converted into sulphur dioxide by means of an acidic substance, the sulphur dioxide being further used in different process steps.
