In Finland’s vast forest lives a monster with a voracious appetite. Once, it would have been called a pulp mill. But after a recent makeover costing €1.2bn ($1.3bn) it is now known as a bioproducts mill—and as such is one of the biggest in the world. This sprawling plant, near Äänekoski, a town in the centre of the country, consumes 6.5m cubic metres of wood a year. That translates into the delivery of a large lorryload of felled tree trunks every six minutes, day and night, together with yet further logs arriving on 70 railway wagons a day. Apart from a brief break for maintenance once a year, the mill never stops working. …Metsä Group, which operates the Äänekoski mill is ultimately controlled by a co-operative belonging to more than 100,000 families who have each owned large chunks of the forest for generations. For every tree harvested, four saplings are planted.
