Evaluate the feasibility of industrial-scale injection moulding of recycled polypropylene composites reinforced with recycled fibers.
Conducted injection moulding trials in four independent industrial companies in Andalusia and three case studies in Slovenia under real production conditions.
Characterized the extrusion process for stability and operational efficiency, focusing on automated dosing and stable material flow.
Assessed injection processing parameters including cycle stability, part quality, and defect formations.
Confirmed continuous operation with stable material flow and process stability.
Observed strong cycle repeatability and consistent operations under industrial conditions.
Provided critical insights into the scalability of recycled natural fiber-reinforced polypropylene composites.
