(Dortmund) Once again, the three trade shows Solids, Recycling-Technik and Pumps & Valves showed during their two-day appearance in Dortmund how much potential there is in the industries. On 29 and 30 March, 5,251 visitors were convinced by the innovative strength of the companies from the fields of process and recycling technology. In addition to the exhibition, the audience was particularly enthusiastic about the top-class supporting programme and lectures. Topics such as plastics and building materials recycling or digitalisation were the focus of the presentations. On the new Impuls Center stage, key note speakers from outside the industry also allowed visitors to look beyond their own horizons.
