B&M Longworth’s story begins in 2004, when the company’s engineers received patent protection for the DEECOM® invention, a revolutionary method for reclaiming high value industrial stainless steel from polymer filters and other manufacturing components. The method uses steam and pressure to depolymerise polyester, to melt and reclaim a pristine filter for multiple re-use. DEECOM® was low in environmental impact, using pressure, super critical steam and emitting only water vapour.
In 2010, Longworth was advised to explore other applications for the technology as a reclamation for value waste streams. After research trials into the reclamation of carbon fibre from aerospace grade composite waste for Boeing in 2011 proved successful, Longworth filed for a second patent in various regions worldwide, based on the use of this technology for waste management. Clemson University stated that DEECOM® recovered fibres for Boeing were ‘pristine’ and difficult to distinguish from virgin grade material.
DEECOM® FOR PLASTICISED AND COATED TEXTILES
For carpets, fast fashion, technical fabrics and flame retardant fabrics.
Following a number of projects with partnerships in the textiles, technical fabrics and the garment industries, Longworth has become involved with innovative developments using DEECOM® for the reduction, reclamation and separation of textiles waste.
One project, acknowledged by the government’s Select Committee in December 2021, saw the full circularity from waste polyester ‘fast fashion’ garments into accessories for new garments and items for the supply chain, reducing the need for raw materials used by this industry.
Longworth’s EU funded Galactica project proved the separation of nylon and elastane in waste swimwear and gym wear can now be achieved. Previously this had been assumed as impossible.
Textiles is a hugely important area of interest for Longworth, realising significant environmental and sustainability outcomes.
