Switzerland-based mountain sports outfitter Mammut is raising the bar in resource conservation and performance for the 2024 winter season with the launch of its Mammut Loopinsulation. This groundbreaking insulation solution marks another significant step towards a more environmentally friendly future.
Mammut Loopinsulation is the result of a successful collaboration with Austrian rope manufacturer Teufelberger. This innovative insulation material is made from production scraps generated during industrial rope manufacturing. Through a mechanical recycling process, free of chemicals, these scraps are transformed into high-quality insulation. “With Mammut Loopinsulation, we are embracing a circular and resource-conscious approach to material reuse. This is a critical step toward the future of sustainable outdoor clothing,” explained Helena Theba, Material Management lead at Mammut.
From concept to innovation
The development of Loopinsulation began after an analysis of Mammut’s carbon footprint in 2018, which revealed that 13 percent of the company’s CO2 emissions came from rope manufacturing. In response, Mammut conducted extensive research on repurposing rope production scraps, leading to the creation of Loopinsulation, a technology that stands out for its efficiency and environmental benefits.
First milestones and challenges
For the 2024 fall and winter season, Mammut has successfully recycled 12 tons of rope scraps, converting them into valuable insulation material. A key challenge was the variation in rope diameter, quality, and color, which was overcome through innovative solutions and a robust logistics system. “The complexity of recycling processes should never be underestimated,” says Theba. “A circular economy demands significant effort and expertise.”
A practical example: The Sender IN Hooded Jacket
One example of Loopinsulation in action is the Sender IN Hooded Jacket. This insulation jacket combines Loopinsulation with a recycled, wind- and water-repellent outer shell, moving Mammut closer to a fully circular, eco-friendly production process.
