The Nordic Polymer Days 2019 took place for the 56th time. This time in Norway (Trondheim), where the sun never sets (almost). Young speakers made this polymer conference a very family but scientific event. The TCKT was present with the topic "Melt filtration of polymers", which was an important contribution in the category "Environmental Aspects of polymers". In addition to the award-winning posters and presentations, there were also some social program, such as an organ concert in the Nidaros Cathedral and a conference dinner at the Banksalen Restaurant. The 57th Nordic Polymer Days 2020 will take place in Finland and we hope to be back with a contribution.
