Extrusion lines for WPC pellets and profiles

Polywood technology for processing fibres and polymers

Extrusion lines for WPC pellets

Bausano lines for WPC (Wood Plastic Composite) pelletizing transform vegetable fillers such as sawdust, rice husk or natural fibres into highly homogeneous technical pellets, combining them with recycled or virgin polymers such as PVC, PE, PP or PLA. The resulting material is ideal for the subsequent extrusion of profiles for decking, panels, urban furniture, fencing and ventilated façades, with consistent performance and reduced environmental impact. The MD series parallel twin-screw extruder ensures efficient mixing and controlled plasticization, even with high percentages of natural filler. Compared with other technologies, Bausano lines stand out for mechanical reliability, thermal stability and low specific energy consumption, making them a preferred choice for the industrial production of WPC pellets.

Extrusion lines for WPC profiles

Bausano designs complete lines for the extrusion of structural WPC profiles, intended for decking, outdoor cladding, balustrades, slats, soffits, planters and outdoor furniture components. At the heart of the line is the MD series parallel twin-screw extruder, which ensures homogeneous plasticization and uniform fibre distribution, even on complex or hollow sections. The patented Multidrive system reduces mechanical stress on the screws, extending their service life and improving energy efficiency. Compared with competing solutions, Bausano lines stand out for modularity, digital integration and final profile quality, reducing maintenance times and ensuring continuous production with high aesthetic and dimensional standards.

What is WPC and why it is a sustainable alternative

WPC, or Wood Plastic Composite, is a composite material made from a blend of vegetable powders and thermoplastic polymers. It is designed to replace wood in applications where durability, resistance and sustainability are key requirements. Used in construction, urban furniture and outdoor applications, WPC maintains the natural look of wood while reducing maintenance costs and vulnerability to external agents. It can be extruded into pellets or finished profiles, with aesthetic and functional customisation according to project needs. Choosing a Bausano WPC line means offering the end customer a more stable, durable and competitive product, with tangible advantages in terms of efficiency, sustainability and added value.
Main advantages of WPC:

Versatile, can be processed like wood
Resistant to corrosion, weathering and UV rays
Resistant to insects, including termites
More cost-effective than wood
Wood-like aesthetic appeal, also for furniture applications
Does not require large-scale maintenance or special treatments for laying
Excellent thermal insulator
Flame retardant

Polywood technology

Bausano designs and manufactures turnkey extrusion lines for WPC production, managing every stage of the process, from formulation to material processing. Thanks to its proprietary Polywood technology, developed to optimize the processing of wood-plastic composites, it is possible to obtain profiles and pellets with consistent mechanical properties, high dimensional stability and superior aesthetic quality. Each line is configured around the customer’s application requirements and ensures integration, operational continuity and sustainability. Bausano solutions are a benchmark in the sector for industrial reliability, process control and finished product quality.

100% Recyclable

WPC (Wood Plastic Composite) is a sustainable material made by combining vegetable powders with recycled or renewable polymers. It is produced from agricultural or industrial by-products such as fruit stones, rice husks, cork, sawdust and wood flour, mixed with plastic matrices such as PVC or PE, without the use of chemical binders. Unlike other mineral fillers, which involve high disposal costs, WPC can be fully recycled and reintroduced into the production cycle, with a reduced environmental impact. The material can be ground, regranulated and extruded again, creating new products without significant loss of quality. A solution that reduces waste and improves the overall efficiency of the process.

Raw material

The term WPC (Wood Plastic Composite) defines a family of composite materials designed to combine the mechanical properties of polymers with the aesthetic quality and sustainability of natural fibres. Its composition includes a balanced blend of vegetable components such as wood flour, rice husk, almond shells and agricultural waste, combined with a synthetic thermoplastic matrix, usually PVC, PE, PP or PLA, also in recycled form. The result is a strong, workable and stable material, suitable for the production of extruded profiles, panels and pellets. Technical additives complete the formulation, improving processability, UV protection and durability in outdoor environments. WPC is a reliable alternative to traditional materials in construction, urban furniture and industrial fittings.
