Y Knot? Rope maker goes biobased


In Germany, Gleistein Ropes has announced it will shift its ropes currently produced using DSM’s Dyneema-brand ultra-high-molecular-weight polyethylene fibers to the biobased version of the UHMWPE material. 

“These fibers possess exactly the same trusted strength and reliability of their conventionally sourced counterparts, yet contribute substantially to climate protection due to their renewable, bio-based raw material,” Gleistein says in a press statement. “This results in a significant reduction in carbon emissions and fossil fuel dependency. With this move, Gleistein is adopting the leading role worldwide among textile rope manufacturers aiming towards becoming carbon neutral in the future.”

To make biobased Dyneema, DSM extracts crude tall oil from wood pulp sourced from sustainably managed forests. Gleistein expects the switch will reduce its carbon footprint by around 1,000 metric of carbon dioxide annually, which is equivalent to taking more than 210 passenger cars off the roads.
