Bausano at GreenPlast with new single-screw extruders for polyolefin recycling

At the second edition of the GreenPlast fair, taking place at Fiera Milano in Rho (Milan) from 27 to 30 May, Bausano will showcase for the first time its new E-GO R single-screw extruders, designed to enhance the efficiency of polyolefin recycling processes. Available in sizes 44, 47, and 50 L/D, with a total of eight models, the E-GO R series combines the most advanced extrusion and regranulation technologies for the recycling of polyolefins such as HDPE, LDPE, and PP derived from industrial and post-consumer waste.

The new generation of E-GO R extruders, capable of handling higher throughputs in the range of 45/37 to 210/37 L/D, can process up to 1,500-1,800 kg per hour of non-flowing material and up to 1,700-2,000 kg per hour of flowing material. These new extruders are proposed as the ideal solution for recycling lightweight materials with a moisture content of 5-6%. Thanks to a dual high-performance degassing system, residual moisture and volatile substances are removed during the process, thus preventing the formation of defects in the pellet, such as "air bubbles," caused by gases present in the input blend or generated during the extrusion phases. The E-GO R series stands out for the high quality of the extruded product, a result of Bausano's expertise in screw design, the geometry of which is specifically engineered to prevent excessive mechanical stress on the material entering the extruder, which could lead to degradation of the molten mass.

The E-GO R extruders are equipped with a dosing system designed to suit the specific characteristics of the material. It consists of two hoppers, the first with a flat bottom and volumetric feeding, and the second with forced feeding to compact the material before it is extruded. Finally, the line is completed with a liquid ring or immersion cutting system.

“To achieve the objectives of the latest PPWR Regulation, industry players are called upon to invest in efficient solutions capable of reintegrating highly contaminated plastics materials, often characterised by high levels of moisture and post-wash impurities, into the production cycle,” commented 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 able to quickly respond to the new needs of the sector, thanks to an even richer portfolio today, which is a concrete expression of the added value that has always characterised Bausano's offering”.
