20 years of Science Night captivated both young and adult visitors alike.

On November 8, 2024, RWTH Aachen celebrated the 20th edition of the Science Night “5 vor 12”. The IKV exhibition gave visitors the opportunity to immerse themselves in the world of plastic processing in a vivid and engaging way.

Every year, the RWTH Science Night offers a special platform to make science and research accessible to a wide audience in an entertaining and vivid way. In its anniversary year, the Science Night offered over 80 individual events at ten different locations and attracted visitors of all ages.

The central venue was the C.A.R.L. lecture hall center in Claßenstraße, where IKV devoted itself intensively to the topic of plastics technology and plastics recycling. The IKV exhibition enabled visitors to immerse themselves in the world of plastics processing in a vivid way and experience modern solutions for a more sustainable use of plastics.

For the youngest visitors, the IKV offered an interactive waste separation game that conveyed the importance of correct waste separation in a fun way. Another highlight was the live demonstration of the injection moulding process in miniature format – the production of clamping components provided a practical explanation of the plastic moulding process.

Adults and those interested in the subject were able to familiarize themselves with various plastic recyclates in a special demonstration and follow the process from plastic waste to recycled material. The practical demonstrations were supplemented by comprehensible explanations from IKV employees, who emphasised the added value of a functioning circular economy.

The presentation by Prof. Dr. rer. nat. Dahlmann on the topic “It’s complex – plastic recycling!” perfectly. Despite the late hour, his presentation aroused great interest and prompted many visitors to ask questions. Here it became clear how complex the challenges and opportunities in plastics recycling are.
