content of presentation
Content of presentation:
  • What is wool-rich carpet (WRC), and what are its attributes?
  • What are the challenges to recycling?
  • Current progress with recycling WRC
  • Opportunities
  • Conclusion …..
wool rich carpet
Wool-rich carpet:
  • Wool:
    • a natural & renewable resource
    • high in nutrients
    • good insulation properties
    • very good water absorption properties
  • WRC is an inseparable mixture of wool, nylon, polypropylene, jute & polyester
  • Note different constructions of woven and tufted carpet
recycling challenges
Recycling Challenges:
  • Opposing properties, e.g.
    • land spreading
    • external ménages
  • Cost and capacity of shredding machinery
  • Transport costs – need local solutions
  • But landfill cost increases are encouraging entrepreneurs to find solutions
progress todate
Progress todate:
  • Energy recovery – UK and USA
  • Land restoration programmes
  • Trials with shredded carpet into various products (confidentiality agreements in place)
  • Animal bedding trials
  • ‘Yes if’ meeting with the EA on WRC being applied to the land
progress todate cont
Progress todate (cont.):
  • Aware of WRC shred being used as a component within Green Roof growing media
  • Composting discussions - UK and USA
  • Land usage in sports surfaces (in Portugal)
  • Brick manufacture (in India)
wrcs benefits
WRCS benefits:

“wool/wastes offer a source of major plant nutrients which could be used to replace inorganic sources, and valuable organic matter which could be used to replace soil organic matter lost as a result of normal agricultural activities.”

technical information for wrc
Technical information for WRC:
  • 10% Nitrogen w/w
  • 1.4% Sulphur w/w
  • 70% Carbon w/w
  • pH 6.4
further opportunities
Further Opportunities…..
  • Insulation properties
  • Construction related, e.g.
    • composite materials
    • embankment design
  • Absorbent properties
  • 100,000 tonnes pa available in UK
  • Others? !!!
to conclude
To conclude …..

“We all know you can’t recycle wool-rich carpet” – anon nylon carpet representative, (Florida 2008)

  • Wool-rich carpet is rich in environmentally beneficial properties, and with some effort progress is being made
  • Wool-rich carpet has an excellent start to its life cycle, we are aiming for its end of life to be as good!!
