- Annotation: This review presents a comprehensive analysis of modern methods for processing and extracting hemp bast fibre – a key technological step determining the quality and cost of the final product. Traditional, chemical, biological, and physical-mechanical methods, along with their advantages and disadvantages, are considered. It is shown that the choice of method depends on the intended use of the fibre and the balance between cost effectiveness and environmental safety. Hybrid technologies combining preliminary physical-chemical processing with subsequent biological processing are recognised as the most promising. Particular attention is paid to the prospects for further development of these methods, including the creation of new enzyme complexes and the implementation of closed-loop waste recycling systems.
