E GO R Series for the efficient recovery of post industrial waste

E-GO R Series: productivity and quality in polyolefin recycling

The E-GO R Series is developed to transform HDPE, LDPE, PP and other thermoplastic materials into high performance recycled pellets, even with contamination, moisture or irregular bulk density. The integrated degassing system removes volatile components and reduces odour formation, helping improve the quality of regenerated material and the stability of the production process. Each line is designed to process a wide variety of waste, including light printed films, compacted materials and densified materials. Forced feeding ensures a constant flow even with difficult materials, while automatic filtration and cutting systems deliver a uniform output, ready for reuse in new applications.

Compact, flexible and modular, E-GO R meets the needs of manufacturers and recyclers aiming to increase productivity, reduce energy costs and improve process traceability. Integration with digital control systems supports operational optimisation, even under variable working conditions.
Designed and manufactured entirely by Bausano, the E-GO R Series is a concrete solution for companies that want to enhance the value of plastic waste, support the circular economy and maintain high standards of quality and long term reliability.

Advanced polyolefin recycling: stability, continuity and value recovery

In post industrial recycling, the regeneration of HDPE, LDPE and PP requires technologies able to process heterogeneous materials, including contaminated inputs, while preserving the functional properties of polymers. Thanks to their thermoplastic nature, polyolefins are ideal for reprocessing through extrusion, but only an advanced control system can deliver stable, homogeneous pellets ready for new applications. The Bausano E GO R Series meets these needs by integrating plasticising and pelletising in a single high efficiency process.

High density polyethylene, or HDPE, is widely used for the production of pipes, bottles and rigid containers. During recycling, it may contain contaminants such as inks, adhesive labels, metals or moisture. E GO R technology enables controlled and uniform melting of the material, followed by effective degassing and filtration systems that retain solid impurities, delivering pellets suitable for new technical applications.

Low density polyethylene, or LDPE, used in films, bags and flexible packaging, is more subject to bulk density variations and is often contaminated by organic materials or printing residues. The E GO R system can feed and melt light or densified materials, ensuring a stable process even with uneven inputs. The result is a regenerated material with good mechanical and dimensional properties, ready for reuse.

Polypropylene, or PP, is used in high temperature applications such as food containers, pharmaceutical bottles, caps and technical components. During recycling, it may be mixed with fibres, pigments or additives. Extrusion with E GO R makes it possible to homogenise the melt while maintaining the thermal resistance and processability of the material, even in the presence of complex contaminants. The modular configuration of the line allows treatment to be adapted to different levels of purity and particle size.

E GO R technology: a reliable platform for the circular economy

The Bausano E GO R single screw extruder is designed for high performance industrial recycling. From plasticising to pelletising, each phase is engineered to maximise value recovery from post consumer or post production plastic waste, transforming it into regenerated pellets with constant quality. Thanks to its ability to process materials with variable contamination, the E GO R Series is a concrete solution for promoting a more sustainable, efficient and traceable production cycle.

E- GO R technology: process architecture for the technical regeneration of polyolefins

The E-GO R single screw line is designed to transform a wide variety of post industrial and post consumer plastic waste, even with high levels of contamination and morphological variability. Processable materials include mixed PE and PP packaging films, printed PE and PP films, PP thermoforming flakes, washed PE films, LDPE agricultural waste, LDPE stretch films and rigid regrind containing blends of PE, PP, ABS and PS. The modular approach of the system allows the process to be configured according to the polymer characteristics, the contamination level and the required quality of the final product. The plasticising unit features a single stage screw with an optimised geometry profile and L/D ratios up to 47, specifically designed to generate high melt uniformity, even in the presence of contaminants. The single or double degassing zones, with high vacuum technology, efficiently remove moisture, volatile substances, residual solvents and light organic fractions, helping prevent chemical instability and improve the mechanical performance of the pellets. Filtration is ensured by manual or automatic screen changers with double station plate or piston systems, suitable for different levels of solid contamination, such as glass fibres, metals, printing residues and mineral fillers. The cutting system can be selected from strand pelletizer, water ring or frontal air cutting, according to the type of material and the intended use of the final pellets. In terms of performance, the E-GO R line is available in sizes from 45 to 210 mm, with motor powers from 30 to 640 kW and output from 30 to 2000 kg/h, differentiated according to light or heavy material. Integration with IoT platforms and advanced HMI systems enables complete traceability of process parameters, predictive maintenance management and real time energy optimisation. This technology is particularly suitable for the regeneration of technical resins with degraded molecular structure, which can be improved through inline dosing of functional additives, compatibilisers and thermal stabilisers, obtaining compounds with mechanical properties comparable to those of virgin material.

Purification and cutting technologies in the E-GO R configuration

Degassing system

The single or double degassing system removes moisture, air and volatile compounds from the melt, improving pellet quality and process stability, even when processing contaminated or hygroscopic materials.

Inline screen changer

Automatic or manual filtration systems remove solid contaminants such as metals, paper, sand and inks, ensuring a clean melt flow, protection of downstream equipment and constant pellet quality.

Water cutting

Pelletising can be carried out with a water ring system or a strand system, depending on the viscosity and type of material. Both solutions ensure uniform pellet size and controlled cooling, even with filled materials or high fluidity polymers.
