  1. Wool-Rich or Rich-Wool Carpet? David Clissold Brintons Ltd dclissold@brintons.co.uk

  2. 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 …..

  3. 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

  4. 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

  5. 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

  6. 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)

  7. 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.”

  8. Technical information for WRC: • 10% Nitrogen w/w • 1.4% Sulphur w/w • 70% Carbon w/w • pH 6.4

  9. Further Opportunities….. • Insulation properties • Construction related, e.g. • composite materials • embankment design • Absorbent properties • 100,000 tonnes pa available in UK • Others? !!!

  10. 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!!
