Swiss mountaineering brand Mammut has collaborated with Teufelberger, a rope manufacturer based in Austria, to create a new high-performance thermal insulation. It is made from industrial rope manufacturing production waste using a mechanical recycling process.

The genesis of the new Loopinsulation, as it is called, goes back to 2018, when Mammut first calculated the carbon footprint of its activities. It learned that 13% of its CO2 emissions were due to rope manufacturing. Repurposing production scraps into insulation was seen as a way to reduce its footprint.

Loopinsulation was introduced in the brand’s autumn-winter 2024/25 collection, and is the result of 12 tonnes of recycled rope waste. The company said that a key challenge was addressing variations in rope diameter, quality and colour. “The complexity of recycling processes should never be underestimated. A circular economy demands significant effort and expertise,” commented Helena Theba, material management lead for the brand.
