  1. Materials Resource Efficiency in ConstructionMark Collinson, WRAP EAUC Annual Conference, 18th April

  2. What is WRAP? • Waste and Resources Action Programme • funded by DEFRA • helps to minimise landfill, reduce carbon emissions and improve our environment • encourages and enables business and consumers to be more efficient in their use of materials

  3. WRAP’s focus

  4. UK material flows in construction Overall material consumption by construction industry (>400 Mt per year) Quantity of construction and demolition waste generated (120 Mt per year UK) M tonnes Waste construction materials landfilled in the UK (60 Mt per year)

  5. UK waste arisings

  6. Recycled content in construction

  7. Which of these products contain recycled content?   65% 80% Lightweight block Plasterboard   >80% 100% Glasswool Aggregates

  8. Perceived barriers • higher recycled content will cost more

  9. Identifying opportunities to increase recycled content • WRAP maintain data on three benchmarks of recycled content for construction materials. • Standard: level of recycled material content likely to be used if no request for recycled content is made • Good: a higher level of recycled content than standard practice, but readily available at competitive cost (cost neutral) • Best: highest level of recycled material content currently available in the UK

  10. Good Standard Best A cost neutral opportunity % Recycled Content Cost (£)

  11. Perceived barriers • higher recycled content will cost more • products suffer from quality and performance issues

  12. Examples of mainstream products

  13. Perceived barriers • higher recycled content will cost more • products suffer from quality and performance issues • availability problems

  14. Perceived barriers • higher recycled content will cost more • products suffer from quality and performance issues • availability problems • a 10% minimum requirement is difficult to achieve

  15. 10% - readily achievable across sectors

  16. Perceived barriers • higher recycled content will cost more • products suffer from quality and performance issues • availability problems • a 10% minimum requirement is difficult to achieve • finding and measuring recycled content is onerous

  17. The recycled content toolkit • calculates the recycled content ‘standard practice’ baseline • identifies the largest Quick Win (movement towards ‘good practice’) opportunities, using information on basic dimensions and key design specifications • provides pre-formatted performance reports:

  18. Which concrete block should I buy ? 65% 40% 25% 5%

  19. Selecting quick wins

  20. Selecting quick wins

  21. Selecting quick wins

  22. Selecting quick wins • WRAP reference guide provides a directory of products with higher levels of recycled content. • can be built into existing material selection processes • selected Quick Wins specified by performance characteristics • designers and contractors review the practicality of Quick Win options • capital cost and availability • durability • quality / aesthetics • buildability

  23. Recommended wording ‘….at least 10% of the total value of materials used should derive from recycled and reused content in the products and materials selected.  In addition, show that the most significant opportunities to increase the value of materials derived from recycled and reused content have been considered, such as the top ten Quick Wins or equivalent, and implement good practice where technically and commercially viable.’

  24. Practical examples of recycled content usage

  25. Case study – University Halls of Residence • Queens University, 2006 • Opportunities to increase recycled content: • dense blockwork • carpet tiles • low strength concrete • hardcore • Plasterboard. • Use of recycled content (as a % of total value of materials): • standard practice: 15% • readily achievable at equivalent cost: 25% • maximum achievable but at extra cost: 37%

  26. Case study – Hospital design options • St Barts and The London Hospitals, 2005 • Opportunities to increase recycled content: • services • flooring • brickwork and block-work • sub-structure • roofing • concrete frame • lifts • curtain walling / cladding. • Use of recycled content (as a % of total value of materials): • Standard practice: 19% • Readily achievable at equivalent cost: 30%

  27. Case study – Waste recycling infrastructure • Dundee and Merseyside city councils, 2005 • Opportunities to increase recycled content: • capping and sub-base. • fill materials. • concrete (using cement replacement materials and recycled aggregates). • asphalt. • drainage products. • topsoil (e.g. incorporating compost). • Use of recycled content (as a % of total value of materials): • standard practice: 5-9% • good practice at no extra project cost: 50-63%

  28. Building Schools for the Future minimum threshold for recycled content in model Output Specification Bradford University minimum recycled content requirement in refurbishment programme Leeds Metropolitan University corporate policy for minimum requirement for new buildings Taking action in education

  29. Who is taking action? • Glasgow City Council • Newcastle City Council • Solihull MBC • British Land • Welsh Health Estates • Greater London Authority • Northern Ireland Procurement Directorate • Defence Estates • Building Schools for the Future (BSF) • National Grid • Raploch Urban Regeneration Company • Skanska • Scottish Executive • NOMS • … and many, many more

  30. Summary

  31. Summary • increasing recycled content has a tangible impact on resource efficiency • setting a requirement is easy to do • no impact on: • cost • design or specification • quality • other project goals • WRAP support for: • policy and project wording • calculating recycled content • identifying products • a quantifiable, demonstrable contribution to a sustainability or CSR strategy.

  32. Recycled paper advocacy team • 8 consultants covering the UK • paper and print related backgrounds • technical advice and support • recommended specification for recycled content • explain to organisations the environmental and business benefits of using recycled paper • FREE
