To ensure that chemicals are used safely, Stora Enso’s mills work continuously to improve chemical management systems. Chemical contact persons or chemical working groups at the mills screen and approve new chemical products to ensure that all products used in mills are environmentally acceptable and safe to use.

At Stora Enso’s Swedish mills, products already in use are evaluated on an annual basis to determine if they can be replaced with safer, non-hazardous alternatives. At Norrsundet Pulp Mill, for instance, sodium hydrogen sulphite is now used instead of sulphur dioxide in the bleaching process. Other mills have replaced insulation materials, sealants and oil products.

Whenever necessary, chemical risk assessments are performed and the results are used to improve safety.
