“Biodegradability is an end-of-life solution that works in harmony with the circularity model. With the ability to renew our fibres, we are changing the conversation to circularity.”
US advanced materials technology company PrimaLoft has said that its PrimaLoft Bio fibres are now renewable in a circular economy, after third-party testing proved the polyester fibres were capable of being chemically recycled.
According to PrimaLoft, this process breaks down polyester to its basic components so it can be rejuvenated into a new high-performance material, without compromising its original integrity.
In a statement, the company claimed it was the first brand to introduce a 100% recycled, biodegradable synthetic insulation and fabric that supported circularity.
“The intention of PrimaLoft (@PrimaLoft) Bio was always to address the eventual end of life of a garment in an impactful way, while finding a solution for the industry-wide microplastics issue,” said PrimaLoft president and CEO Mike Joyce.
He added: “Biodegradability is an end of life solution that works in harmony with the circularity model. With the ability to renew our fibres, we are changing the conversation to circularity. Circular economies are the next frontier in sustainability and we have proven our capabilities in this space.”
According to PrimaLoft, third-party testing has shown that PrimaLoft Bio fibres can be chemically recycled with a 95% yield rate. After chemical recycling, PrimaLoft Bio fibres may be reused to produce new insulation or fabric fibres, while maintaining the same level of performance.
Joyce said that more than 8.3 billion metric tonnes of plastic had been produced worldwide, since 1950, and less than 10% of those plastics has actually been recycled, adding: “Those numbers are alarming and PrimaLoft is working on solutions to reduce the use of oil-based virgin polyester fibres.”
He explained: “To that end, we have been using recycled polyester fibres sourced from plastic bottles in our products since 2007. Through this traditional mechanical recycling process, new high-performance material can be created. However, this method cannot be used repeatedly without eventually sacrificing the performance characteristics of the polyester and continuing to use additional natural resources. That’s why PrimaLoft searched for new ways to close the system.”
Prima said that its material will only biodegrade when exposed to the naturally-occurring microbes in landfill or bodies of water. Therefore, the fabric remains highly durable throughout its usable lifecycle in a garment, the company said.
