SOREMA’s TRAMU agglomeration unit for chemical recycling

With its SOREMA division, Previero provides a continuous agglomerator with double degassing and calender – TRAMU – for chemical recycling of plastics.

TRAMU, a continuous agglomerator with double degassing and calender, is a solution for the pyrolysis challenge in chemical recycling.

Challenge of chemical recycling

Chemical recycling is now emerging as a key step in closing the plastics recycling loop, particularly for handling heterogeneous plastic fractions that pose a challenge for mechanical recycling.

However, a major challenge in pyrolysis process occurs. It needs to process mixed plastic fraction, composed of light, thin, flexible plastics with densities below 50-80 kg/m³ and high moisture content, and convert them into dense, dry product with densities above 300-350 kg/m³ while maintaining consistent quality.

Revolutionary solution for chemical recycling

To solve this challenge, TRAMU agglomerates plastics at a temperature 20-30% lower than that of a standard extruder, and removes moisture and gases at ambient pressure. By operating the machine under these conditions, the TRAMU boasts low energy consumption.

Wear and tear has been greatly reduced, while final density is ensured by degassing and calendering before final grinding.

TRAMU is available in three models, each suitable for different scales of operation, with capacities from 600 kg/h to 3000 kg/h.
