Title: Materials Resource Efficiency in Construction Mark Collinson, WRAP EAUC Annual Conference, 18th Apri

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
WRAPs focus
4
UK material flows in construction
Overall material consumption by construction
industry (gt400 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

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

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

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
Taking action in education
  • 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

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
