Smart recycling and compact efficiency

At K 2025, Gamma Meccanica will present its new Smart line alongside upgraded Tandem Smart solutions. The new Smart line is designed to deliver maximum performance in a compact format. Developed to simplify operation, it only requires the user to input the recipe and hourly throughput in kilograms–after which the system automatically manages all processing parameters, drastically reducing the margin of error. One of the line’s key strengths is its compact design: with equal productivity, it takes up less space and enables more efficient installations, even in areas with limited room. Furthermore, the optimised layout improves accessibility for maintenance, cutting downtime.

The Smart line introduces a compacting screw with integrated by-pass, allowing direct additive injection (e.g., for colour changes) in record time, with no risk of material backflow or contamination. The bearing assembly is independent of the shredder, allowing for quicker, easier disassembly without having to dismantle the entire unit. Tests carried out on the Smart 5 + DUO1750 configuration demonstrated excellent energy efficiency, with consumption ranging between 0.21 and 0.28 kWh/kg, depending on the material processed (e.g. post-consumer LDPE, PP nonwoven, or HDPE flakes with CaCO3). These values place the Smart line among the best in its class.

Gamma Meccanica will also present a new advanced degassing system for its Tandem Smart lines. This patented solution features a retractable die-holder slide, allowing the die to be cleaned without disassembly or shutting down the thermoregulation system–cutting downtime from 90 minutes to just 20. The new degassing chamber ensures a more uniform vacuum flow and simplified maintenance, while maintaining high efficiency in gas removal. In parallel, the system is equipped with an advanced deodorisation module (also patented), which enables targeted gas treatment through the injection of additives (e.g. supercritical CO₂) to reduce odours and contaminants.

Among the innovations on display is the new TTA (Taglio in Testa ad Anello) ring-face cutting system, which is compact, precise, and particularly quiet–reducing noise by 3–4 dB. It guarantees high-quality pellet production for a wide range of applications. Available in two models – TTA 10 and TTA 30, with hourly throughputs of up to 1,000 kg and 3,000 kg respectively – the system ensures: uniform cooling and consistent residence time for the pellets; stable flow during immersion; fast die changeover; simplified spare parts management. TTA is compatible with a wide variety of plastics, from LDPE to PP.

The new lines also feature a modern, cohesive aesthetic, consistent with the company’s integrated design philosophy. Functionality, efficiency, and visual harmony come together in a range of machines that not only perform well, but also stand out. At its K 2025 stand, Gamma Meccanica will not only showcase new technological solutions but will also present a forward-looking vision of recycling – where efficiency, responsibility, and intelligence converge.
