The German Institutes of Textile and Fiber Research Denkendorf (DITF) and LEKI Lenhart GmbH have jointly developed an innovative hiking pole composed largely of renewable raw materials, marking a significant step toward sustainability in outdoor equipment. The new product demonstrates that natural fibers can deliver both high performance and environmental benefits.
Consumers are increasingly seeking eco-friendly alternatives to energy-intensive materials like aluminum and carbon fiber, which are difficult to recycle. To meet this demand, DITF and LEKI’s research project focused on creating durable sports poles using hemp fibers and a bio-based matrix, produced through the pultrusion process.
Hemp Fiber Innovation and Bio-Based Matrix
The hiking pole shaft is crafted from regionally sourced hemp fibers processed into rovings using the Kemafil process — a unique wrapping technique that interweaves fibers into a strong, rope-like structure. The matrix, developed with Bio-Composites and More GmbH, is derived from epoxidized linseed oil and can be cured similarly to synthetic epoxy resin. Containing up to 42% organic material, the matrix is highly compatible with the energy-efficient pultrusion process.
At DITF, researchers successfully produced 16 meters of tubular profiles on a laboratory scale, achieving smooth-surfaced components with visible natural fiber textures. Industrial-scale production trials at CG TEC GmbH confirmed the process’s suitability for series manufacturing.
Over 64% of Components from Renewable Raw Materials
Beyond the shaft, other parts of the pole also emphasize sustainability — the wrist strap is made from natural fiber fabric, and attachments are formed from bio-based polymers. Altogether, more than 64% of the hiking pole’s components come from renewable sources.
Initial market analyses reveal strong commercial potential and positive user feedback. The new poles match the bending strength of aluminum while providing superior damping properties. By significantly reducing its carbon footprint, this innovative hiking pole offers a sustainable and high-performance alternative for environmentally conscious consumers.
DITF and LEKI expressed gratitude to the Federal Ministry of Food, Rural Affairs and Consumer Protection of Baden-Württemberg for funding the Hanf-Profil research project that made this development possible.
