PrimaLoft, a supplier of advanced material technology solutions, has introduced PrimaLoft Bio, claimed to be the first synthetic insulation made from 100% recycled, biodegradable polyester fibers.
In accelerated test conditions simulating a landfill environment (ASTM D5511) PrimaLoft Bio fibers achieved near complete biodegradation in 394 days, compared with the negligible degradation observed for standard polyester under the same conditions.
Developed over the past four years, this proprietary technology does not change the performance, look or feel of the garment, and is expected to be available to consumers in the third quarter of 2020, said the company of Latham, New York, USA.
PrimaLoft Bio fibers break down when exposed to landfill or the ocean: the fibers have been enhanced to be more attractive to the naturally occurring microbes found in these anaerobic environments.
The biodegradation process leaves behind water, methane, carbon dioxide and biomass (expired microorganisms and organic waste). PrimaLoft Bio insulation will only biodegrade when exposed to the microbes in landfills or ocean water, thus the insulation remains highly durable throughout its usable life cycle in a garment, said chief executive officer Mike Joyce.
The idea arose in 2014 from PrimaLoft’s product management. After two years of research, it took two years to develop the process and more than a year of testing with an independent laboratory.
PrimaLoft Bio expands on the company’s commitment to providing sustainable solutions throughout its business. To date, PrimaLoft has saved more than 84.7 million plastic bottles from landfills and transformed them into premium insulation products.
By 2020, 90% of the company’s insulation products will have at least 50% post-consumer recycled content, without compromising performance. Earlier this year, PrimaLoft introduced its first insulation with 100% post-consumer recycled material.
