  1. Welcome to … The South West Composites Gateway/ Advanced Composites Manufacturing Centre Workshop on Life Cycle Assessment of Composites

  2. My background … • UWIST (now Cardiff) BSc chemistry/polymer • Thames (now Greenwich) MSc physics of materials • Plymouth PhD hybrid composites • RNEC HMS Thunderer composite structures • Plymouth ACMC comp. manufacturing • Plymouth PGDipEd (Adult Ed.) • increasing interest in quality/sustainability issues

  3. My background (continued) • CEng Chartered Engineer • CEnv Chartered Environmentalist • CSci Chartered Scientist • FIMMM, FInstNDT, FIAQP • EPSRC Peer Review College • CIMNFC Programme Steering Committee • DTI Technology Programme assessor • FP6 BioComp reviewer

  4. Advanced Composites Manufacturing Centre • composites research in Plymouth since 1967 • focus on manufacturing since the 1980s • NAB-funded ACMC launched 1987 • BEng Composite Engineering since 1990 • BSc Marine and Composites Tech since 2001 • CPD for industry >2500 delegates

  5. Commercial activity… some examples

  6. Sustainability • Brundtland: “Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs". • Three (or four) “pillars”: • Economic • Environmental • Social • Governance

  7. Mankind is her/hisown worst enemy • Population over 7 billion and rising • “world population peaks at 9.22 billion in 2075” (World Population to 2300,United Nations, 2004) • “10.9 billion by 2100” (World Population Prospects: The 2012 Revision, United Nations, 2013)

  8. From UN 2013 report …

  9. Resources … • are finite as we have only one planet • every additional person will expecttheir fair share of the total 10.9b/7b is a 56% increase one fair share is reduced to 64% of the total resource Do not do (the wrong) things right, but do the right thing

  10. Rant over … … but for the composites industry we need life cycle assessment/analysis: • thermosets vs thermoplastics • natural vs man-made fibres … to satisfy all stakeholders … and to provide quantitative evidence that the chosen route is the correct choice

  11. Philosophy TodayMarch 2005 • Ben Basing on Our Responsibility to Future Generations • “… the major issue in valuing thingsfor future generations, is the fact thatdifferent people value the same thing differentlyand the same person might give the same thing different values at different times …..we will have real problems trying to assesswhat will be of value to people livingin an inevitably changed world”.

  12. Thermoplastics vsthermosets • Thermoplastics + recycle at similar duty • high process temperatures • use limited to process temperature - 200°C • Thermosets + low process temperatures + usable at temperatures close to process - re-use limited as fillers

  13. Natural vsman-made fibres • Natural + Carbon neutral • fertilisers, herbicides, pesticides • variable quality • dispersed production • Man-made fibres + uniformity of product - high-energy production processes • Nilmini Dissanayake, PhD, Plymouth, 2011 • Life cycle assessment of flax fibres for the reinforcement of polymer matrix composites • http://www.tech.plym.ac.uk/sme/acmc/lca.htm

  14. End of life • Reuse • Design for dis-assembly • Recycle • Pyrolysis • Incineration • Composting • but biogas is ~60-65% CH4, 35% CO2 • Landfill

  15. Drivers:producer responsibility • End of Life Vehicles (ELV) Directive (2000/53/EC) • Waste Electrical and Electronic Equipment (WEEE) Directive(2002/96/EC) • largely driven by landfill considerations • thermosets are difficult to recycle • but thermoplastics use high temp processes

  16. Life cycle assessment • very diverse options are available for the design and manufacture of composites • most LCA are qualitative • can we compare chalk and cheese in a quantitative way ?

  17. … penultimate slidefrom QCC Code of Conduct • “the only stupid questionis the one that is not asked” • Samuel Ho “Operations and Quality Management” Thomson Business Press, 1999, page 197.
