Insulation Manufacturers Tout Recycling Successes

For the first time, this survey includes data from both US and Canadian manufacturing facilities.

According to the survey, NAIMA and NAIMA Canada members together used more than 2.2 billion pounds of recycled post consumer glass and blast furnace slag in the manufacturing process of thermal and acoustical insulation.

Manufacturers in the United States increased use of recycled materials by 12 percent from 2003’s level and 17 percent since 1992. Over the past 12 years, NAIMA members' plants in the United States have diverted nearly 26 billion pounds of recyclable materials from the waste stream.

"Our members continue to take steps to employ environmentally friendly activities at all levels of production - from the initial use of recycled materials in the manufacturing process to the end product," said Ken Mentzer, president and CEO of NAIMA. "Fiber glass and rock and slag wool insulations are some of the best choices available for residential and commercial green building."

Canadian facilities used more than 321 million pounds of recycled glass and more than 61 million pounds of slag to the manufacturing of thermal and acoustical insulation products. U.S. facilities used almost 1.2 billion pounds of recycled glass and nearly 670 million pounds of slag to produce fiber glass and slag wool insulation products.
