Customer case:

Stora Enso Varkaus PM3 grade conversion rebuild

Growth in traditional retail and e-commerce is increasing global demand for sustainably produced packaging materials. In 2015, Stora Enso’s Varkaus mill in Finland converted their existing paper machine into a board machine to produce linerboard to better meet the market need for renewable packaging. They chose Valmet as their partner for this challenging rebuild.

Having one supplier for technology, automation and fabrics for the start-up makes our lives easier. Besides making start-up smoother, this set-up makes sure that
everything works together in an optimized way, including in the tune-up phase. Together with just one supplier, we can improve productivity and quality in a very efficient way.
