Stadler helps Schroll recycle more with brand-new facility

Recycling technology specialist Stadler has completed a new recycling plant for Schroll Group in Vosges, France. The site has a processing capacity of 80 000 tonnes per year and features advanced sorting equipment to treat various packaging materials. 

The new recycling facility features two independent sorting lines – one for the treatment of multi-material and one for hollow material, ranging from paper to plastics and metals.

The multi-material plant takes in the whole 15-tonne/hour input, which is fed into a Stadler PPK ballistic separator and two Stadler STT2000-8-1 ballistic separators for mechanical sorting. This is followed by optical separation with four Near-Infrared (NIR) devices, and the process is completed with manual sorting.

The final output fractions of this line include cardboard, film, newspapers and magazines as well as hollow materials. These are then fed into the plant’s second sorting line.

The hollow materials line, with a throughput of 4 tonnes per hour, sorts the fractions mechanically and optically, with a final manual sorting. It uses a Stadler STT2000-8-1 ballistic separators, a magnet, a separator for non-ferrous metals and five NIR devices, to produce an output of clear and coloured PET, PEHD, Tetrapak, aluminium, film, mixed paper and residual fractions.

The plant was designed to enable for future expansions and the installation of robots. ‘This set-up gives more flexibility by allowing, for example, to work on one line in 2 shifts and in 1 shift on the other line,’ explains Stadler’s sales manager Clément Stehlin. ‘The Stadler machines in this line are perfect for this purpose and exactly dimensioned for potentially higher throughputs in the future.’

This project marks another collaboration for the two companies. Stadler constructed the first sorting centre for Schroll Group in 1999. Since then, it built 5 more sorting plants and renovated another facility.
