Resource-saving innovation: Mammut Loopinsulation

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," explains 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% 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.
