Fiberglass is very stable against climatic influences as it does not degrade by natural processes. This creates challenges when disposed but it is a valuable property for outdoor noise barriers.

Recycled fiberglass products are therefore very durable, and the sound-absorbing material can be reused again and again in future noise barrier elements.

We foresee to be able to offer a return policy for any damaged or dismantled products, allowing us to repurpose the recycled materials. In this way we will participate in the circular economy, using all our resources responsibly.


Using recycled fiberglass within noise barriers replaces more expensive and energy-intensive materials, thus contributing to reducing society’s overall CO2 output.

COWI — the global consultancy — has analyzed the recycling process for fiberglass for use in noise barrier elements and compared it to the corresponding manufacturing process for corresponding materials made of aluminum and mineral wool.

They conclude that Miljøskærm’s® product (recycled fiberglass in a frame of recycled plastic) reduces CO2 emissions by ~60% and energy consumption by ~40%.

A sensitivity analysis shows there is potential for further reduction of both CO2 load and energy consumption.
