Recycling Line Boosts PET Melt Quality
At K Show and an Off Site Open House, BB Engineering demonstrated its innovations for PET recycling.
BB Engineering, a joint venture of Bruckner Maschinenbau and Oerlikon Barmag, presented a PET recycling line called Vacufil at October’s K 2022 Show in Dusseldorf.
Vacufil uses the liquid state polycondensation process for recycling PET. It combines large scale filtration and regulation of intrinsic viscosity. A key component is the patented Visco vacuum filter, which removes volatile impurities. Vacufil can be used for both post-consumer and post-industrial input materials.

Vacufil is modular, and can be configured for downstream processes, including the BB Engineering’s own Variofil spinning plant. The Variofil produces a polyester yarn.
K Show attendees who went to an open house at BB Engineering during the trade fair saw this combined process in action. Its facility in Remscheid is less than 30 miles from Dusseldorf.
