3M has "significantly" reduced the carbon footprint of producing its Thinsulate Insulation by developing new insulation materials made from up to 100% post-consumer recycled waste.

While recycled Thinsulate insulating materials have been in used in skiwear for years now, the firm says 2018 saw significant improvements in the materials' structure and function.

"By producing new insulation materials made from up to 100% post-consumer recycled materials and committing to turning process-related waste into high-quality plastics, 3M has managed to significantly reduce the carbon footprint of the production process," the company said.

The range comprises three products, including 3M Thinsulate 100% Recycled Featherless Insulation which offers a sustainable, cruelty-free alternative to natural down insulation solutions. Its recycled polyester material gives "excellent protection" even in extreme conditions whilst also being more durable than natural outwear materials tend to be, the firm says. In addition, 100% Recycled Featherless Insulation is less bulky and more lightweight than most natural materials, and it performs well when wet. 

Meanwhile, 3M Thinsulate Flame Resistant and 3M Thinsulate Water Resistant processes and materials have been certified for their sustainability, their positive environmental impact and their safe production methods by independent agencies such as Oeko-Tex, Global Recycled Standard, and Bluesign.
