The ICCM23 is one of the famous international conferences in the plastic industry. I learned by joining the conference and speaking to other scientists and doctoral students. There were people from all over the world who presented their current research work. The experiences I got at the conference helped me to improve my skills and expand my knowledge. I can recommend everyone to take the opportunity and have such an experience themselves. It was enough time to do e.g. sightseeing or to get together with other participants of the conference e.g. in restaurants, at the conference itself or in leisure time. In Belfast you should visit the Titanic Museum and the ship docks where the Titanic was built. I can also recommend a city sightseeing tour and going to an Irish pub.
