This work reports the mechanical extraction process of Finola hemp fibres from the agri-waste of the food industry. FINOLA is a breed of hemp that is grown in cold climates for grain production, including EU countries. However, after harvest, the residual stalks of these plants are considered low-value waste by-products. In this paper, we aim at optimizing the methodology to extracting the short fibres from these agri-waste residue of FINOLA hemp, and to use them to produce higher-value technical textiles that can be used in many industries, such as construction and automotive, as an alternative to fossil-based fibres. Mechanical extraction, with a multiple-step process had been developed for this residue. The obtained fibres showed the potential of use as a material to produce nonwovens from 100% hemp or hemp blends with other fibres. This process is foreseen to increase the efficiency of this agricultural resource and contribute to circular economy and sustainability of textile sector.
