Recycling and minimizing waste

Recycling

For more than 30 years recycling has been an important focus area for the ROCKWOOL Group. We recycle our own waste from the majority of our operations as well as the waste from other industries.  

Recycling ROCKWOOL stone wool products

First and foremost, we have made it a high priority to ensure that our own ROCKWOOL stone wool products are recycled as much as possible. Waste material, refurbishment and demolition waste along with off-cuts - all of these can be transformed into new ROCKWOOL insulation. In fact, 75 % of our own stone wool waste is recycled, a figure we are aiming to make even higher in the future. 

Preventing waste disposal from other industries

The nature of the ROCKWOOL production process also offers excellent opportunity for recycling secondary (or residual, as before) materials from other industries. This is a win-win situation, as it both solves a waste disposal problem and cuts down on the use of virgin raw materials.

Recycling secondary raw materials

Thanks to our advanced melting technology, we are able to use secondary raw materials from other industries directly in the melting process.
This represents a step forward as the traditional technology requires waste materials to be processed into briquettes before they can be used in the cupola furnace. 

However, the new technology has also posed some initial challenges in terms of the number of different materials we are able to recycle. Over the past few years, we have continued to sustain a high degree of recycling secondary raw materials, as well as developing the new technology and we will continue to do so even further in the future.
