Stone wool is a natural product made primarily from the volcanic rock basalt. Basalt is a sustainable raw material, sourced directly from our earth and is almost inexhaustible: every year the earth produces 38.000 times more basalt than is used for the production of stone wool by ROCKWOOL.

Stone wool is produced in a sustainable and environmentally friendly way and is 100% recyclable. The high-tech production process ensures that the stone wool products are made in a way that is as sustainable and environmentally friendly as possible.

The environmental impact of stone wool for water management is visualized in our infographic, see downloads on the right side.

This Life Cycle Assessment (LCA) is a method to quantify the total environmental impact of a product throughout its life cycle. All environmental aspects of the extraction of the necessary raw materials as well as those of the production, transport, use and disposal of the product are taken into account.

An important environmental aspect is the contribution of a product to the emission of greenhouse gases, expressed in terms of (GWP, Global Warming Potential).

An LCA can also be used to compare the overall environmental impact of products and systems throughout their life cycle. The analysis in the accompanying infographic shows that the GWP contribution of Rockflow (water management system based on stone wool) is considerably less than that of plastic systems.

Besides that, stone is robust and functionality is unabated during its entire lifespan. It requires no maintenance or replacement. 

Additionally, stone wool is 100% recyclable to new stone wool of the same quality. Stone wool elements for water management systems are partly made from recycled stone wool. Since 1992 ROCKWOOL has its own recycling process in place where waste material from our own production process and building sites is re-used for the production of new stone wool products. Where possible also waste materials from other industries is utilized in this recycling process.

Stone wool elements for water management are in part produced using recycled stone wool. 

 

Stone wool therefore is the ideal fit for a building process where environmentally friendly products are preferred.
