Advanced material technology company Primaloft has announced 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. This recycling process breaks down polyester to its basic components so that it can be re-used in new material. Primaloft Bio fibres are made from 100 per cent post-consumer recycled material and are said to break down when exposed to specific environments – such as a landfill or the ocean. The company says it has now enhanced this to be more attractive to the naturally-occurring microbes found in these environments, so that they eat away at the fibres at a faster rate, returning the fabric or insulation to natural elements.
