Stone wool can be indefinitely recycled

  • Rock is one of the most abundant raw materials on the planet, but we still need to make better use of our planet’s resources. We have developed our technology in a way that allows us to use waste from other industries as alternative raw material. The building sector produces a third of all waste, much of which ends up in landfill today. So we also have to prevent our building products becoming waste. We do that by making recyclable, long-lasting products and offering a recycling service where viable. Currently we only offer recycling services on building insulation in European markets where short distances support closed loop recycling as the most sustainable solution.
  • In North America we are focusing on OEM waste. When this is established, we will continue to look for recycling opportunities.
  • Our products can be easily removed when a building is renovated or demolished and recycled back into new products. In fact, stone wool can be recycled again and again into new stone wool. This is an important element of a ‘circular’ business model – another way you can be a part of our vision for sustainable cities of the future.
A portion of the catalog proceeds goes to the National Park Foundation
