Project Aims

• The objectives of this pilot project were
• To demonstrate the potential to collect CD data
  for waste planning from tools such as SMARTWaste
  Plan
• To determine the limitations of the data
  available
• To determine where there are data gaps and
• To produce recommendations for improved data and
  recommendations for waste minimisation.

3
Additional aims

• The information available has been used to
  produce
• An estimate of CD waste arisings for the East of
  England broken down into waste type. Information
  about the amount of waste reused or recycled (on
  or off site) and sent to landfill.
• Information about the quantities and types of
  waste collected and managed in each
  county/unitary authority.
• A forecast of waste arisings on an annual basis
  to 2031.
• Recommendations for reducing CD waste sent to
  landfill.

4
Production of performance indicators

• Data from completed projects on the SMARTStart
  and SMARTWaste Plan tools has been used to
  produce the following performance indicators
• Volume/tonnes waste produced per 100m2 floor area
• Volume/tonnes waste produced per 100K project
  value
• Volume/tonnes waste produced by waste product
  type per 100m2 floor area
• Volume/tonnes waste produced by waste product
  type per 100K project value

5
Project types

• Performance indicators have been produced for
  new build construction projects and for
  refurbishment projects for the following project
  classifications

New build construction performance indicators
7
Other Performance Indicators

• Refurbishment projects - a set of performance
  indicators similar to those for new build
  projects has been produced for refurbishment
  projects
• Demolition projects - not enough data was
  available from SMARTWaste about completed
  demolition projects to produce reliable
  performance indicators
• Excavation work - SMARTWaste Plan has the option
  of entering the work package for waste arisings
  (e.g. demolition, excavation or construction).
  However, not enough information is currently
  available to produce performance indicators for
  excavation waste.

Other sources of waste data used

• Construction Statistics Annual and National
  Statistics website data about construction
  output from these sources has been used in
  estimation of waste arisings.
• National Federation of Demolition Contractors
  (NFDC) data from the NFDC has been used to
  assist with estimating demolition waste arisings.
• Communities and Local Government Survey of
  Arisings and Use of Alternatives to Primary
  Aggregates in England, 2005 this has been used
  to assist with estimating excavation waste
  arisings.

Estimate of waste arising by waste type for East
of England, 2008

• Performance indicators for individual waste
  products have also been produced from completed
  projects on SMARTStart and SMARTWaste Plan
• These performance indicators have been applied to
  construction output to provide an estimate of
  waste arising by product from new build
  construction and refurbishment

16
Waste management options

• Completed SMARTWaste Plan projects were analysed
  to determine the waste management methods used
  overall and for different waste products.

17
Waste management options by waste type

• Detailed analysis of the data from completed
  projects on SMARTWaste Plan was carried out to
  determine the waste management methods for each
  waste type.
• An estimate of amounts of waste reused, recycled,
  recovered or disposed on and off site from new
  build and refurbishment has been made for East of
  England, 2008.
• E.g. timber waste arisings for the East of
  England, 2008 were estimated to be 183,263 tonnes
  and it has been estimated that 34 of timber is
  recovered off-site. This gives an estimate of
  timber recovered off-site in the East of England
  of 62,685 tonnes.
• A summary for the main waste products is shown

Estimate of waste arising from new build
construction managed in East of England, 2008

• Results show that the majority of waste (84) is
  managed off site and that the majority of bricks,
  inert and concrete wastes are reused or recycled
• Data from the RATS Interrogator about the origins
  of waste received at waste management sites has
  not been considered in this project

20
Trends in waste arisings

• Performance indicators have been used to estimate
  waste arisings from 1996-2008 based on
  construction output.
• There has been a steady increase from 1996 to
  2007.
• In 2008, there was a slight decrease in line with
  the economic downturn.
• Information from the NFDC also shows a slight
  decrease from 2007.

Forecasts of CD waste arisings, East of England

• Performance indicators produced from SMARTWaste
  Plan can be used to forecast waste arisings if
  information on project value or floor area is
  available
• Data is available on predicted residential new
  build construction from the Regional Spatial
  Strategy
• Based on this information, it is estimated that
  waste arisings from residential new build in East
  of England will remain steady at approximately
  484,000 Tonnes/annum from 2010 to 2031.
• More data on other planned construction activity
  such as education, healthcare and road-building
  projects is needed to forecast waste arisings.

23
Conclusions

• Data from the SMARTWaste system can be used to
  produce performance indicators
• The performance indicators for new build and
  refurbishment projects can be used to estimate
  waste arisings
• For demolition and excavation, alternative
  sources of information have been used to estimate
  waste arisings
• Waste arisings from exempt activities have not
  been included.

24
Conclusions

• More information on construction output for
  specific project types such as education and
  commercial projects is needed to assist with
  estimating and forecasting waste arisings.
• More information is needed at a district level as
  this is currently limited to residential new
  build.

25
Recommendations for waste minimisation

• SMARTWaste Plan collects information on waste
  minimisation actions used together with the users
  views on how effective these actions have been.
• This information has been analysed to determine
  the waste minimisation actions most commonly used
  and these include
• Site levels designed to minimise excavation
• Waste concrete re-used as fill on site
• Pre-fabrication e.g. timber frame off-site
• Plasterboard improved storage to minimise
  damage, waste sent to manufacturer for recycling
  and changing specification to minimise cutting

26
Recommendations for improving data available

• SMARTWaste Plan should be amended to
• Include information on exempt activities
• Require information on work package of waste e.g.
  demolition, excavation, new build to be entered
• Make the tool more applicable to civil
  engineering projects
• It is recommended that local authorities request
  a Site Waste Management Plan and that a tool such
  as SMARTWaste be used. This will allow more data
  to be collected which can be aggregated and
  analysed to inform waste policy
