Our story begins in 2004, when engineers at our sister company B&M Longworth (Edgworth) Ltd received patent protection for their invention DEECOM®, a revolutionary method for cleaning high value industrial stainless steel (st st) filters using steam to depolymerise polyester melt and reclaim a pristine filter for multiple re-use. DEECOM® changed the way our customers handled component cleaning by discarding of the need for solvents such as harmful and costly tri-ethylene glycol (TEG) and was low in energy use and environmental impact, running off steam and emitting only water vapour.
After successful research trials for Boeing in 2011, we were advised to file for a 2nd patent in various regions worldwide, based on the use of this technology for waste management. We affectionately call this IP DEECOM®lite
Late 2017 saw the first patent granted in China, followed over the next three years by remaining countries and regions around the world.
And so, in 2018-19 came the partnerships with carefully selected industry leaders and institutions we needed for the true R&D of our world-beating technology, along with another couple of patents pending.
What is DEECOM®lite?
“DEECOM®lite is a low energy, low impact, clean process with capabilities of reducing the waste plastic and composite issues across a wide range of industries.”
DEECOM®lite is a patented process, requiring a clean water supply and power (usually fuel or a gas boiler but can also be electric) in order to create high temperature, low pressure ‘clean’ steam in a pressure vessel environment. The sequence of compressions and decompressions (hence the name) over time create a ‘molecular earthquake’ and shatter the molecular chain of plastics, rubber and resin composites (in the case of polyester from 220 molecules into 12s and 20s), effectively breaking down the polymer and (reverting to) the original monomers, which is then easier and faster to biodegrade.
What happens then?
Whilst a low-grade ‘waste’ output, valorisation to aide recycling and re-use is also possible in some cases with the help of our chemists’ catalyst capabilities.
