North America: A survey by the North American Insulation Manufacturers Association (NAIMA) has revealed that its members used over 0.3Mt of recycled blast furnace slag in the production of thermal and acoustical insulation in 2017. The survey included data from both US and Canadian production plants.
Producers also used over 0.9Mt of recycled glass to produce residential, commercial and industrial thermal and acoustical insulation. Since the industry’s recycling program began in 1992, NAIMA estimates that its members’ plants have diverted an estimated 26Mt of recycled materials from the waste stream.
“Our industry is tremendously proud of the substantial use of recycled content in the production of energy saving insulation products,” said Curt Rich, president and chief executive officer (CEO) of NAIMA. “These products ultimately reduce building energy use and decrease our carbon footprint. Over the long term, the fibre glass and mineral wool insulation industry expects to continue using substantial amounts of recycled content in the production of insulation products.”
