The Birdlime 1R 9.8 climbing rope is a follow-up to Edelrid’s Swift Eco 8.9, the primary PCA/PFA-free dry-treated rope. Because the 2019 providing, the model has expanded its eco-friendly efforts.
Edelrid launched the Neo 3R 9.8, the primary climbing rope comprised of used cords, in 2023. In 2024, it launched a partly recycled harness and climbing helmet, finishing a recycled mountaineering “kit.”
Straying away from petroleum-based synthetics seems like a pure development in climbing gear, and castor oil has been confirmed in different client items.
Castor Oil? However How?

Bio-based plastics and textiles aren’t new. Created from castor oil, polyamide-11 (Nylon 11) began promoting in France in 1945. Nonetheless, this bio-based various has not develop into mainstream, presumably as a result of it nonetheless prices greater than its petrochemical cousin, Polyamide-6.
The manufacturing of bioplastics from plant oils is just like making plastics from petroleum. Each use chemical processes, like polymerization and condensation, to control long-chain acids. These bioplastics are developed in areas the place “regular” plastics are already manufactured to forestall a complete overhaul of manufacturing amenities.
Different vegetation are appropriate for the manufacturing of different plastics and textiles. Corn, wheat, sugar cane, and potatoes are generally utilized in a course of that leverages the excessive sugar content material. Soybean oil, corn oil, and rapeseed oil are different oils common for bio-based uncooked supplies.
Different plant supplies, comparable to algae and even bacterial fermentation, are sources of bioplastic, however scaling as much as make an actual affect has been difficult and dear.
Right here’s a recipe for making corn-based bioplastic in your kitchen for the industrious and curious. You solely want corn starch, corn oil, water, meals coloring, and a microwave oven.
Is This Actually Extra Sustainable?
The Birdlime 1R 9.8 is extra sustainable as a result of it makes use of considerably much less petroleum to supply, which is Edelrid’s main aim with this wire.
This is the reason the rope carries the model’s “1R” nomenclature: 1R represents decreasing using non-sustainable supplies in manufacturing, 2R means reusing supplies in manufacturing, and 3R means recycled supplies make up the ultimate product.
It could be handy (and simple to imagine) to assert that the Edelrid Birdlime 1R 9.8 will biodegrade. However there’s a catch.
The castor oil-based bioplastic within the rope will technically biodegrade, however solely below sure circumstances. These circumstances embrace temperatures of 122 to 158 levels Fahrenheit. So, in brief, the a part of the Birdlime rope comprised of castor oil will biodegrade at an considerable price in an industrial compost facility however not in your yard backyard.
Once more, Edelrid’s main aim in growing the Birdlime climbing rope was to cut back petroleum use. It’s prudent to maintain all of it in context; the quantity of petroleum saved on this rope is a really tiny, incremental achieve in sustainability throughout the complete out of doors trade and even in climbing alone. However, it’s a begin.
