Hello, I’m Jonathon from Rochester, Michigan. I am currently a Plant Biology major, and am planning on switching to biosystems engineering soon. I was very interested in this study abroad because I have been very interested in the way other countries utilize their natural resources and how those strategies can be applied in the U.S. After graduation I plan on working with renewable energies, more specifically algal biofuels.
In the morning of May 15th, we will begin by traveling to the Energy Technology Centre(ETC) in Piteå, Sweden. Piteå is located 100 km south of the Arctic in the Norbotten region of Sweden. The industrial focus of Piteå is energy and sustainable development. Apart from its industrial focus, Piteå is also home to a strong nature-driven tourism industry.

At the ETC, we will be listening to a lecture by Olov Öhrman about the research being done at the centre and Smurfit Kappa. After the lecture we will be taken on a guided tour of the facility. Later in the day we will take another guided tour, this time of Smurfit Kappa, by Peder Fahlman. Smurfit Kapa is a leading producer of paper-based packaging in the world. Smurfit Kappa employs over 41,000 people and has production sites in 32 countries.
In the morning we traveled about 45 minutes south of Luleå to Piteå, Sweden. At our first stop in Piteå, we visited the ETC. At ETC we attended a presentation by Olov Öhrman of the ongoing projects that the nonprofit is working on. The main focus of the presentation was biomass and the Pressurized Entrained flow Biomass Gasification (PEBG). During this process, biomass is heated to temperatures exceeding 1000 ˚C at high pressure and low oxygen levels. As a result of the low oxygen heating, syngas (H2+CO) is produced, which can be used directly as an energy source, or converted to methanol to be more energy dense. At this time, ETC is currently working on optimizing their process for the gasification of black liquor with hopes of using it for lower quality biomass like bark and other tree matter.

After visiting the ETC building, the group had lunch and proceeded to start a tour of the Smurfit Kappa paper mill, led by Pedar Fahlman. The paper plant, which produces large sheet paper for the outside of cardboard boxes, is the largest of its kind in Europe. The tour led us through many of the machine-filled and awe inspiring portions of the facility. Unlike many other paper mills, this plant uses sustainable fuels and cogeneration to aid in supplying its energy needs. The mill can currently produce about half of the energy needed to produce its paper, drastically lowering the amount of energy they need to purchase. With waste heat from the plant’s energy production, the mill is able to dry wood chips to aid in efficiency, heat liquor for chemical recovery, heat water for fiber washing, and provide district heating for the town of Piteå . By providing heat for the town, the mill is able to increase its overall profit.

After the tour in the Smurfit Kappa mill, we traveled back to LTU for a presentation on the economics of woody biomass by Robert Lundmark. Sweden has over 4 billion hectares of forest land, with the production of woody biomass increasing at an average of 3% per year. The growth of biomass exceeds the rate of harvesting, allowing for an increase of biomass production without an adverse effect on the environment. The biomass throughout Sweden consists mainly of private owners (50%), public companies (14%), and private companies (26%) . To complement the large volume of biomass available in Sweden, the country utilizes policy to persuade companies to spend resources on improving technology.
