At my home department – Adam

Hello! My name is Adam and I’m located in Gruvön in the R&D department. The R&D department is divided into two groups; the Research group, or Tech center, and the Development group – where I’m in the latter. I’m one of six trainees located at Gruvön.

Now, after a couple of months of acclimatization to the workplace and introductions of different processes and products I have finally begun feeling that I’ve got the hung of it. At first, the flow of information could almost be experienced as too much but now things are starting to make sense. It’s kind of like the in the university when you sit there at the first lectures and doesn’t get anything of what the teachers is trying to say – but after a month you finally get it.

The distribution of trainee activities and work assignments during the trainee year are distributed as the following: 60% trainee activities and 40% work assignments. It’s a good mix of learning and doing actual work – and we are allowed to hastening slowly. Apart from the learning process of the trainee activities my actual work includes a large proportion of learning. Due to the startup of KM7 there’s a need for knowledge in certain areas, and my focus area has so far been LPB (Liquid Packaging Board). This contains a ton of both skype and actual meetings with experts in different areas – everything from the process of making paper/board to the coating. Further, a lot has been about learning about the customers and their final products.

The trainee-activities includes a mix between educational meetings and theme visits. About a month ago we visited the forestry department and got the opportunity to see how the first process in making a paper is done. We got to see how the trees was chopped down, which was an incredible process, and how the trees are replanted.

The trainee-team exploring the small treeplants that’s in about 60 years will be full grown trees.

Wednesday the 7th of November I was at the mill in Frövi. We had an education in barriers and a visit to the laboratory. The R&D department had arranged this in order to increase the level of knowledge within the department. After that I visited my trainee-colleagues at Frövi, Linus and Karin. Linus had some spare time so he took me on a tour of the entire mill which was a great experience.

In the beginning of 2019 I will start a parallel project. That project will include doing tests in our Box Lab, for instance different tensile and compression tests. The project will also include a literature study, trying to find analogies from different materials. 

Last week I asked Björn, trainee here at Gruvön, to take me on a tour of PM1-5. He gladly accepted and Marcus, also a trainee here at Gruvön, asked if he could join us. It was really interesting to see the machines irl and hear about Björn’s experience about them.

Lastly, I would like to teach you all some random facts about paper and Billerudkorsnäs. Some may be totally irrelevant, but the goal is for you all to get some perspective of what is happening at Billerudkorsnäs. 

Random facts

Did you know that…
…BillerudKorsnäs has the world’s strongest fluting (the wavy paper in well pap)
…the word well pap originates from the German word “welle”, which translates to wave
…in the start of the paper machine, the grist have a dry matter of pulp under 1%
…KM7 extends to a total of ca 350m long, 8m broad and weight 17,000 ton making it one of the largest board machines in the world
…KM7 has a capacity of 550,000 tons per year which corresponds to 100 million one-liter-milk-packages per day
…98% of Gruvön’s energy demand is covered by bio fuels and over 52% of the electric power is generated at the mill
…1 ton wood results in 500 kg paper
…the production of paper was first developed in China around year 100 A.D. by Cai Lun
...the excess heat energy produced by Gruvön offers district heating to almost 10,000 households
…the excess heat energy produced by Billerudkosrnäs offers district heating to almost 50,000 households
…before the merge 2012, Billerud have had both the name Billeruds and Billerud
