BUSSLIST Group Information

You know us as BUSS AG. From April 10, 2026, this is the home of BUSSLIST Group – and the place to follow everything we do next. BUSSLIST Group unites three specialized process technology companies under one name: LIST Technology AG, BUSS AG and BBA Innova AG. Together, we cover some of the most demanding steps in process engineering – from high-viscosity reactions to temperature-sensitive compounding to cooling and solidification. ◼️ LIST KneaderReactor Technology – since 1966, enabling continuous high-viscosity processing, reactions, devolatilization, drying, crystallization, desublimation and dissolving. Where other technologies reach their limits, the LIST KneaderReactor Technology delivers. ◼️ BUSS Co-Kneader Technology – the original since 1945, compounding continuous highly-filled, temperature- or shear-sensitive materials with a precision that twin-screw extruders cannot match. More than 3,500 systems installed worldwide. ◼️ BBA Cooling Technology – more than 40 years of experience in precise cooling, solidifying and flaking of viscous materials. The decisive last step in a continuous process chain. What unites us: decades of deep process knowledge, built through thousands of realized applications across the chemical, polymer, fiber, food, pharma and life science industries. BUSSLIST Group is part of the Process Solutions division of Jakob Müller Holding AG, a Swiss family-owned industrial group in its fifth generation. Headquartered in Arisdorf, Switzerland and with locations in the USA, Japan, South Korea and China, and installations on every continent. Excellence in Process Technologies.
