Metsä launches next-gen bioproduct mill

In Finland, Metsä Group’s next-generation bioproduct mill in Äänekoski came into operation as planned August 15 with pulp deliveries from the new mill to customers set to begin in early September. The construction project was carried out as planned, in accordance with its schedule and its EUR1.2 billion budget.

Before the bioproduct mill started up, the old pulp mill in Äänekoski was shut down and its dismantling is currently in progress.

The bioproduct mill will achieve its nominal capacity approximately a year after start-up. The mill will produce 1.3 million tons of pulp per year, along with other bioproducts such as tall oil and turpentine. New bioproducts that already complement the product concept include product gas from bark, sulphuric acid from the mill’s odorous gases, and biogas and biofuel pellets from sludge.

With this new bioproduct mill Äänekoski’s industrial ecosystem is developing and growing, and the mill will be a platform for production of new bioproducts. Several processes and product paths are being actively studied. The most important new bioproduct development projects are lignin products, textile fibers, and biocomposites.
