At Greenplast 2025, Bausano is set to unveil its new E-GO R single-screw extruders — high-efficiency solutions for recycling polyolefins from industrial and post-consumer waste. Designed to meet the latest sustainability regulations, the E-GO R series delivers top performance and pellet quality, supporting the industry's shift toward a circular economy.

Extrusion line manufacturer Bausano will be participating at the second edition of Greenplast, the exhibition-conference dedicated to technologies for a more sustainable rubber and plastics supply chain. At the event, scheduled from May 27 to 30 at Rho Fiera Milano, Italy, the company will unveil the brand-new E-GO R single-screw extruders, specifically designed to improve the efficiency of polyolefin recycling processes. Now available in sizes 44, 47, and 50 L/D, for a total of 8 brand-new models, they expand the product range with even more high-performance solutions.

The E-GO R series combines advanced extrusion and repelletizing technologies for the recycling of polyolefins, such as HDPE, LDPE, and PP, derived from industrial and post-consumer waste. With the goal of supporting partners in the transition to a circular economy, Bausano expands its offering with extruders capable of handling higher outputs. Specifically, the new generation of E-GO R, ranging from 45/37 to 210/37 L/D, can process up to 1,500–1,800 kg/h of non-free-flowing material and 1,700–2,000 kg/h of free-flowing material.

E-GO R extruders are ideal for recycling lightweight materials with a moisture content of 5–6% percent. Thanks to a high-performance double degassing system, residual moisture and volatile substances are removed during the process, thus preventing the formation of defects in the pellets, such as air bubbles, caused by gases present in the input blend or generated during the extrusion stages.

E-GO R therefore stands out for the high quality of the extruded product, the result of Bausano’s consolidated expertise in screw design. The geometry of each screw is custom designed to prevent the material fed into the extruder from being subjected to excessive mechanical stress, which could cause degradation of the molten compound.

An additional plus of the solution is the dosing system, designed based on the specific characteristics of the material. Specifically, Bausano offers a system consisting of two hoppers: the first with a flat bottom and volumetric feeding, and the second with forced feeding, which compacts the material before extrusion. Finally, the line is completed by a liquid ring or underwater pelletizing system.

“To meet the goals of the latest PPWR — Packaging and Packaging Waste Regulation — approved on April 24, 2024, industry players are required to invest in efficient solutions capable of reintegrating highly contaminated plastic materials into the production cycle, often characterized by high levels of moisture and post-washing impurities”, comments Marco Masiero, R&D and Test Extrusion Manager at Bausano. “In this context, Bausano positions itself as a strategic partner, able to guide companies through this transition. We are ready to respond to the sector’s new needs, thanks to an even richer portfolio that tangibly reflects the added value that has always distinguished Bausano’s offering.”
