Previero, with its Sorema division has been in the mechanical plastic recycling market since 1974, and is the industry benchmark for high-quality recycling solutions.
Although mechanical recycling is a well-established technology and remains the first choice for plastics recyclers due to its high efficiency, 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.
Today, efficient preparation of the input material by having chemical recycling process the mixed plastic fraction, composed of light, thin, flexible plastics with densities below 50-80 kg/m³ and high moisture content, is a major challenge in a pyrolysis process.
The goal is to convert these materials into a dense, dry product with densities above 300-350 kg/m³ while maintaining consistent quality and low energy consumption.
For this reason, Previero has redesigned in the context of chemical recycling as a revolutionary solution its Tramu, a continuous agglomerator with double degassing and calender. Tramu with modern features has improved its performance and provides a reliable and robust solution to industry challenges.
The main features of Tramu is its ability to agglomerate plastics at a temperature 20-30% lower than that of a standard extruder, and to remove 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.
