The material used to cover the glaciers must be durable, resist harsh elements/time, and be white to reflect and insulate the sun's rays. Fleece covers are one of the only successfully implemented methods to preserve snow and glaciers by protecting the snow below from melting.
Solar radiation is reflected by the white material and on average 50-60% because of that the snow underneath can be conserved. Fleece covers are already in use at various ski resorts. On the Diavolezza glacier in the Upper Engadine in Switzerland, they have been used successfully for more than 10 years.
The fleece used on the Diavolezza is made of polypropylene,
a 100% recycled thermoplastic polymer that lasts up to 5 years.
We are seeking an investigation to find a more sustainable and ecological material that has the same or better technical advantages than the current one.
