    WRAP exists to

   Create stable and efficient markets for
    recycled materials and products, and
   Remove barriers to waste minimisation
    re-use and recycling
    WRAP’s construction focus
   To accelerate the transition of construction
    waste to a useful, recycled material
       Waste minimisation and management
       Reprocessing C&D wastes
       Procurement of recycled content
WRAP and construction

 A two thirds reduction in consumption of fossil fuels and virgin materials is needed to achieve a
 sustainable and globally equitable level

Headline Construction Figures

   One of the UK’s most productive sectors,
    contributing almost 9% to the GDP
   50% UK energy consumption associated
    with buildings – construction & use
   90% non-energy minerals extracted used in
    construction - <1% new buildings uses
    reclaimed materials
   Biggest consumer of material resources:
    420 million tonnes/year

   need       specification    selection      evaluation     management

               Key point of

European Commission handbook on environmental public
“As a contracting authority, you have the right…to demand a minimum
percentage of recycled and reused content where possible”.

  “The (project) brief should include an outcome-based requirement for
  overall materials efficiency, such as a minimum requirement for
  recycled content in the project .”
     Using your procurement strategy
     to drive resource efficiency

   Sustainable Buildings Task Group:
       Specify 10% or higher minimum
        requirement for recycled content as a
        proportion of the value of materials for
        the whole project
       You can also encourage higher
        performance e.g. through tender
        evaluation criteria
         Commercial advantages
   Potential for cost saving, or cost neutral at least
   Simple way of measuring achievement, which helps…..
        ......developers win credit with planners
        ……local authorities demonstrate policy action
        ……contractors differentiate their performance
        ……clients demonstrate Corporate Social Responsibility
   Leads to lower costs of waste & recycling

Better business, better profits, better building
    Mainstream, not green
   Many mainstream products
    already include recycled content

   A range of products offer
    above-average recycled
    content at no extra cost

   The potential for diversion
    from landfill is substantial

            Mainstream brands          Eco-brands

                   Recycled content

      with comparable performance

   Responding to a project level

For example…

   “At least 10% of the total value of
   materials used in the construction project
   must be derived from recycled and re-
   used content in the products and
   materials selected”.
                   A project level requirement

                   Calculating the recycled content by value

Bricks          2000      £250 per 1000       £500      x      15%     =     £75

Plasterboard    50m 2       £2 per m 2        £100      x      80%     =     £80

Other          25 items          -            £500      x      0%      =      £0

                                TOTALS       £1,100                          £155

                                                        £155 / £1,100 = 14% overall
The opportunities
 in construction
    Identifying opportunities to
    increase recycled content

   Standard: The level of recycled material content most
    commonly available; that is, the material most likely to be
    used if no request for recycled content is made.

   Good: A level of recycled material content better than
    standard practice which is readily available with little or no
    additional effort in cost-competitive mainstream products

   Best: The highest level of recycled material content
    currently available in the UK

         The toolkit helps in the process of setting a
         recycled content requirement and demonstrating
         compliance by:
                Estimating the baseline performance of the
                Identifying the top 10 candidate Quick Wins
                Recording how each selected Quick Win is
                 being achieved
                Producing pre-formatted reports
