Plastics expertise and PET recycling

BB Engineering, Hall 1– Booth D10

As a sub-exhibitor of Oerlikon, BB Engineering presents itself as an expert in extrusion, mixing and filtration as well as an innovator for PET recycling with the VacuFil and VarioFil R+ systems.

Extruders, mixers, filters

As a joint venture of Brückner Maschinenbau and Oerlikon Barmag, BB Engineering took over the extruder division of Oerlikon Barmag in 2002. BB Engineering can thus draw on more than 60 years of experience in extruder construction and is constantly engaged in development work to further optimise its products. To date, approx. 20,000 extruders have been delivered worldwide. The extruders are mainly used in film and synthetic fibre spinning lines for PP, PET, PA and PE. The portfolio also includes various continuous and discontinuous polymer filters from small to large (0.1-40 m² filter area) as well as various polymer mixers.

Recycling technology

BB Engineering has been focusing its development work increasingly on recycling technologies for several years. In addition to extruders, filters and mixers that are suitable for both recycling processes and the processing of recyclate, BB Engineering offers a complete PET recycling plant called VacuFil. With VacuFil, BB Engineering has developed a PET LSP recycling process. It combines gentle large-scale filtration and targeted IV regulation for consistently good rPET melt quality. Thus, much more than simple “downcycling” is possible with VacuFil. VacuFil processes a wide range of input materials – post-production and post-consumer. The patented key component Visco+ vacuum filter removes volatile impurities quickly and reliably. VacuFil is a modular system that can be designed for different recycling applications. There are no limits to the downstream processes. Simple granulation is possible, but also direct feeding into further processing, e.g. in the synthetic fibre spinning mill. BBE offers VacuFil in combination with its own VarioFil compact spinning plant to produce polyester yarn.

Open House

This process can be visited during the K’ show at an open house of BB Engineering and Oerlikon Barmag. Not far from Düsseldorf, at the company’s site in Remscheid, BBE and Oerlikon Barmag will open their doors and give customers and interested parties an insight into the technical centre. Here, visitors can experience the VacuFil Visco+ recycling technology in operation with a connected VarioFil spinning plant and see live how high-quality recycling yarn is produced from PET waste.
