We keep the loop closed

To move away from the current more linear consumption method, the circular economy reduces our material footprint by re-using materials efficiently and profitably. To have a resource efficient world we need to provide the most durable products while simultaneously using the least amount of resources.

 None of our factories send stone wool waste to landfill
 Get a fully sustainable closed-loop product. Stone wool is a reusable material
 Stone wool is a close-loop, fully recyclable material. We don’t down cycle, in fact, it can be recycled again and again...

159.000 tonnes of stone wool were collected for recycling in 2019.

We upcycle waste from others

A complete understanding of the reuse options for a recycling stream (secondary material) needs to be considered when evaluating the sustainable profile of a product.

 We upcycle waste from other industries and create value, stopping them from being sent to landfill. We make use of waste material.
 We don’t divert any scares resources away from other industries.
 We heavily contribute to the circular economy.

An abundant natural resource

Stone wool is an abundant resource and a sustainable construction material. Discovered in Hawaii at the beginning of the nineteenth century, our stone is a natural by-product of volcanic activity that is melted and then spun into natural fibres.

Earth produces 38,000 times more stone material than is used to make ROCKWOOL stone wool annually.

Safe non-hazardous materials

ROCKWOOL stone wool products are safe to live with, safe to install and safe to manufacture.

 This is documented in hundreds of peer-reviewed scientific articles over more than 55 years.
 The WHO’s International Agency for Research on Cancer (IARC) exempts stone wool from its list of “possibly cancer causing agents”
 Our stone wool core is certified to comply with the Note Q for safe mineral wool fibres of EU Regulations (EC) No 1272/2008 and Directive 97/69/EEC
