We're committed to supporting the transition towards a circular economy. Afterall, ROCKWOOL products are circular by nature, so they perfectly complement an economy where products are made from natural and abundant materials, designed for better and more durable use and can infinitely recycled.

Following nature’s lead

In nature, circularity is the norm. All living things exist, die and return to life – sometimes in a new form – in a never-ending circle. Our products are made from natural stone, making it possible to fully recycle used stone wool into new stone wool – over and over again and without any loss of performance.


Rockcycle® is ROCKWOOL’s pioneering recycling program. It’s now available in 19 countries with an aim to reach 30 by 2030.

We take back stone wool material from construction, renovation and demolition sites and recycle it in our production process to make new stone wool products. Rockcycle® facilitates a truly circular and closed loop recycling system. It also caters to the increased demand by key stakeholders for sustainable ways to reduce construction and demolition waste.

By taking a circular approach – where waste is designed out and resources are used efficiently – we can create an economy that is both sustainable and profitable.

Zero waste to landfill

In three-quarters of our manufacturing facilities, we have eliminated all stone wool waste going to landfill. We have done this by re-directing the stone wool production waste back into our production in a closed-loop system.

Globally, we have committed to reducing production waste going to landfill by 85 percent by 2030. We have already reached a reduction of more than 50 percent compared to the 2015 baseline.

Our reduction goal requires us to continuously push the boundaries of what is possible in the transition to a waste-free society. One example is the conversion to electric melting at our factory in Moss, Norway, which has allowed us to significantly increase our recycling capacity.

Reducing and recycling plastic packaging

We use plastic packaging to compress, transport and protect our stone wool products before installation. We are committed to reducing our use of plastic packaging as much as possible, for example by constantly reducing its thickness. We are also committed to increasing the recycled content and recyclability of our packaging.

In 2022, we focused attention on minimising the use of ink on the packaging as a means to increasing its recyclability. We will continue work on increasing recycled content and optimising the recyclability of plastic packaging and streamlining effective solutions across all markets.

Cigacice, Poland

Over the years, we have made several improvements and investments in optimising the water usage across our factories. For example, at our factory in Cigacice, Poland, we invested in harvesting rainwater, which resulted in significantly reducing fresh water consumption.

Vamdrup, Denmark
Since 2000, the Danish factory in Vamdrup has collected rainwater in large basins with storage capacity of 2000 m3, supplying 40 percent of the factory’s production process water consumption.

Saint-Éloy-les-Mines, France
At our French factory in Saint-Éloy-les-Mines, we implemented a system for closer control and quick reaction against water leakages, together with the installation of more water efficient equipment.
