According to Messe Düsseldorf GmbH, plastic products have become an integral part of almost every area of life. Plastic packaging extends the shelf life of food, plastic parts in cars reduce their weight and thus CO2 emissions. In medicine, plastics ensure maximum hygiene standards and make medical products safe. Despite its many advantages, this important raw material has come into disrepute for some time now – because of the plastic waste that pollutes entire regions and floats in huge carpets on the world’s oceans. But this problem can be solved. As the concept of “circular economy” plays a central role in this, it has become a hot topic at K 2019, which will take place from 16 – 23 October 2019 in Düsseldorf, Germany.
