Tree Trip Day 2: Gruvön & Säffle


On the morning of our second day in Sweden our group traveled by car to visit the BillerudKorsnäs mill in Gruvön. In 2016 this mill rebuilt their existing pulp mill including the addition of an ImpBin and pressure diffuser designed by Valmet. Work has also already begun on the installation of a new board machine that will be 400 m long and will increase mill production from 710,000 to 850,000 tonnes per year. Pulp mill production manager, Jonas Lindqvist, provided us with a presentation about the mill and a tour of the pulp mill that included a trip up to the top of the new ImpBin.

By mid-morning our group was on the road again to Nordic Paper in Säffle. This mill produces 30,000 tonnes per year of greaseproof paper. This mill uses a mechanical treatment instead of fluorochemicals to achieve a dense, natural barrier. Nordic Paper utilizes a sulfite and sulphate pulping process as well as a chip steaming process that occurs within a silo to remove fatty acids in an average of two days compared to the two week process that occurs with outside storage. These chips are produced on site using a single log de-barker system. Angelica Uttersäv and Henrik Kjellgren provided our group with a presentation about the mill and the applications of greaseproof paper in food packaging and baking such as the packaging for a stick of butter and cupcake liners. Pulp mill manager, Linda Östberg, gave our group a tour of the mill including the paper machine that was producing green paper to be used as cupcake liners.

In the afternoon our group travelled up the road to BTG Instruments in Säffle. Sven-Arne Damlin organized presentations for our group about the products and services offered by BTG as well as how research is conducted to remain competitive in the market and meet customer specific objectives for process improvement. Our group was given a tour of the on-site facility where many of the instruments are manufactured and shipped directly to the customer. One operator constructs an entire instrument from start to finish in an average of eight hours with a range from four hours to a few days depending on the complexity. Each instrument is then tested at the facility before shipment.
