Sesotec: Profitably closing the plastics cycle

Sesotec has developed a new sorting system for recycling plastic bottles and trays: VARISORT+. The efficiency of this new sorting machine is what sets it apart. Even when working at an incredibly high material throughput of up to eight tons per hour, VARISORT+ detects and separates plastic types, colors, and shapes, as well as metals and foreign objects, with the utmost accuracy and reliability. The newly redesigned VARISORT+ has been optimized for reliable system availability, quick cleaning, and easy maintenance. A rejection accuracy of up to 99% ensures that sorting fractions achieve the highest degrees of purity.

Another advantage of the VARISORT+ system is its flexibility, allowing for the combination of up to three sensors (N = near infrared, C = color/form, M = metal). The sorting system can also be equipped with innovative new FLASH technology for optimal color recognition, which can even detect bottles made with additives. Retroactive sensor upgrades are available at any time and the optional tri-shaft construction enables simultaneous sorting into three material fractions.

VARISORT+ sorting systems are designed to accommodate conveyor belts supplied either by the equipment manufacturer or the customer (working widths of 1024 mm, 1536 mm, 1920 mm, or 2816 mm).

Profits climb due to the flexible system configuration of VARISORT+, which can be adjusted according to the quality of the input material or degree of contamination. As the company states, excellent sorting results with up to 99% purity can be achieved even with poor-quality input materials. The low maintenance and cleaning requirements for VARISORT+ also play a key role in increasing the system’s overall efficiency.

“Plastic waste can no longer be treated as rubbish, but as a valuable resource,” says Michael Perl, Group Director Sorting Recycling at Sesotec. “The solution is a circular economy. This means we need more and higher quality recycling. Sesotec supplies high-performance sorting equipment for this purpose, including the VARISORT+.”
