Because of falling prices for lowgrade PET on the Asian markets, BTB PET-Recycling in Germany wanted to develop new economic solutions and its strategy was to reduce waste volumes.
Bottles undergo several preparation processes before the PET flakes pass through a newly installed Sesotec optical sorting system. This comprises a flake purifier CM 1536 and an existing belt machine which, after modification, can be integrated in the installation.
Sesotec supplied the steel construction, pneumatic conveying technology and control technology for product inspection and sorting material flows, with the aim of co-ordinating processes.
A BTB spokesman said: “Sesotec service engineers can use remote diagnostics for short-term error remedying or software updates, which makes processes in everyday operations much easier.”
