BB Engineering (BBE) and its parent company Barmag will present the latest developments in technology for the processing and recycling of plastics and synthetic fibres at the K 2025 exhibition which is taking place in Düsseldorf, Germany, from October 8-15.

BBE’s single-screw extruders are suitable for a wide range of polymers such as PP, PET, rPET, PA and PE, and are particularly well suited for demanding applications in film production, synthetic fibre spinning and high-quality PET recycling. With screw diameters ranging from 30 to 360mm, they cover a broad processing spectrum for throughputs of 3-6,000 kg/h, depending on the material and process requirements. In addition, BBE also manufactures extrusion cascades for high output rates.

BBE’s latest Cobra melt filter meanwhile sets new standards in continuous polymer filtration and features automatic valve switching and integrated inline intermediate cleaning. This enables continuous operation with consistently high filtration quality, with a maximum filter area of 24 square metres and a throughput of up to 4,000 kg per hour.

Recycling

For many years BBE has been dedicated to developing high- performance technologies for plastics recycling and its VacuFil is a fully integrated system for PET recycling via liquid-state polycondensation.

VacuFil combines large-area, gentle melt filtration with precise  control, ensuring consistently high quality of the rPET melt. The modular system enables flexible adaptation to different material qualities and areas of application in the recycling process with capacites of between 150-4,000 kg/h. The central component of the system is the Visco+, a liquid-state polycondensation unit for targeted viscosity adjustment. Continuous adjustment of the viscosity  results in a homogeneous melt with optimal processing properties for high-quality end products for the fibres, film or packaging industries.

In parallel to K 2025, BBE is hosting open house demonstrations of PET waste being recycled and spun directly into high-quality recycled POY yarns at its technical centre in nearby Remscheid. The yarn is further processed using BBE’s JeTex air-texturising system with a new auto-doffing unit.
