2. History and Workforce Status

Founded in 1966, the company has focused exclusively on KneaderReactor technology for processing high-viscosity materials. In 2023, it expanded its portfolio by acquiring BBA Innova AG, which holds belt/roll cooling technology. On April 10, 2026, the company announced it had formally united with BUSS AG (Pratteln) and BBA Innova AG (Strengelbach) to form the BUSSLIST Group. The three companies described this as a strategic integration — not a restructuring — combining complementary reaction, compounding, and solidification technologies to strengthen upstream process coverage.

Customer relationships continue under the existing entity names for now, with legal integration expected to be completed over the following months (Source: busslist.com official press release, 2026-04-10). Founder Heinz List is credited with developing the Co-Kneader through his research into continuous mixing. The company launched the DISCOTHERM B single-shaft unit in 1974 and, in 2007, supplied the first industrial-scale KneaderReactor for continuous bulk polymerization. Global sites were established in Charlotte, North Carolina, USA in 1990 and in Seoul, Korea in 2017, with a Korea Technology Center opened in 2021. The Jakob Müller Group founded LIST Technology AG in 2016 and the company acquired BBA Innova AG in 2023 (Source: busslist.com official history page).

As a small specialized company of about 39 employees, it is led by CEO Karsten Güdemann. Detailed organizational structure is (undisclosed).
