1890 is a proud year for the Goričane paper mill: a digester is constructed with a volume of 30 cubis metres intended for in-house pulp production. It is the only of its kind on the territory of today’s Slovenia and comes only a few years after the Ritter-Kellner patent for sulfite pulp production. At the time, the paper mill employs 163 workers, who manufacture around 4 tons of printing paper and envelopes, 2 tons of wood pulp and cardboard, and 7 tons of pulp per day.
