Waste

Recycled and recyclable

ROCKFON does not just recycle – it up-cycles. Unlike traditional recycling, in which materials like paper are recycled in a cold process and the fibres are gradually degraded offering limited reuse, up-cycling turns waste into products of greater value. This offers hope for achieving the biggest goal of environmentally minded design: using materials again and again to keep them out of landfills.

With a patented recycling process ROCKFON turns waste materials into new tiles with precisely the same qualities as if virgin materials had been used. Actually it is a little better. Rockfon recycling plants enable precise control of the fibres, ensuring that the stone wool can be classified as biosoluble.

ROCKWOOL and ROCKFON factories receive 500,000 tonnes of waste materials from other industries annually - six times more waste than they send to landfill.

ROCKFON does not just recycle used stone wool products. Inorganic waste (such as slags, metals, blasting sand and ash from burnt sewage sludge) and combustible waste materials are by far the most important sources of secondary materials.

ROCKFON stone wool products contain up to 84% recycled and renewable content, and can be fully recycled at any ROCKWOOL recycling plant at the end of their life cycle.

Avoiding landfil

Today 95% of ROCKWOOL and ROCKFON production waste is either recycled internally or sold to other industries as a raw material for use in their manufacturing processes. To further reduce waste, ROCKWOOL invested over $ 40 million in recycling plants in 2009 and 2010.
