Our Commitment to a Sustainable Construction Industry | Rockfon

Moving from a linear to a circular industry

Abundant, durable, and recyclable resources

Our core material is stone wool made from volcanic stone – one of Earth's most abundant materials. Stone wool is fully recyclable in a closed loop without any loss in performance, and it is also recognised as a highly durable material, reducing the need for replacement and new resources.

Limiting our primary raw material use

Our stone wool manufacturing process can incorporate waste or by-products from other industries, such as slags from the steel industry.

We also collect and include post-consumer stone wool through our Rockcycle scheme, and our facilities minimise waste by re-introducing their internal production waste back into the production process.

A pioneer in recycling and reuse

Though our take-back programme Rockcyle, available in multiple countries, we recycle off-cuts from installation or ceiling tiles at end of life into new stone wool products. Our steel grids are also fully recyclable in a closed loop.

Recently we have gone one step further through successful pilots of direct re-use, leveraging the durability of our products to support a truly circular economy.

Our industry focus in numbers

200

200 tonnes of stone wool from Rockfon products were recycled through the Rockcycle take-back programme in 2024.

65 years

Tests conducted at Copenhagen Airport showed that stone wool retained its performance properties even after 65 years.

243

Each year, the Earth produces on average 243 times more stone through continental volcanic activity than the ROCKWOOL Group uses to produce stone wool.
