Situation today
Policy background
Where do we want to be? National and EU targets
How do we get there? Some key policy instruments
Construction Resources and Waste Platform
C&D Resources & Waste
• 400 million tonnes of
materials used/year
• Up to 120 million tonnes of
CD&E waste – one third of
all waste
• Estimate around 25 million
tonnes of CD&E waste is
disposed of in landfill every
year in England
• Uncertainties around the
data
• High wastage rates
• Rising costs
England Waste Strategy 2007
• Waste as a resource
• Waste policy contributes to
climate change objectives
• Construction and demolition
identified as priority sector for
action
• Focus on 25 million tonnes to
landfill
• Proposed target of halving
CD&E waste to landfill by
2012
Strategy for Sustainable Construction
• Joint Government/Industry strategy
to promote leadership & behaviour
change
Aims to:
• Improve efficient resource use;
• Help firms develop sustainable
products or ways of working;
• Corporate and Social
Responsibility.
Sustainable Construction Strategy – Waste
• Confirmed target of halving
waste to landfill by 2012
compared to 2008.
• Cutting 25 million tonnes to
nearer 12 million. Need to do
some work on baseline data.
• 17 millions tonnes of waste to
landfill is “soil and stones”.
• Subgroup of strategic forum
focusing on C&D waste
Sustainable Construction Strategy – Actions
Waste as a Resource
• Resource availability a growing global issue
• Need to identify barriers to markets for recovered raw
materials from the waste chain
• The Environment Agency working closely with WRAP
on the Quality Protocols
• Pathway to Zero Waste in the South East
Ending waste to landfill?
• Longer term ambition to end disposal of CD&E waste in
landfill as far as practicable;
• But proposed target of “zero CD&E waste” to landfill by
2020 was rejected;
• Landfill remains the most suitable solution for some
(hazardous) waste streams;
• Recycling & recovery capacity will be crucial
• Best practice at >90% landfill avoidance
Revised Waste Framework Directive:
C&D waste target
• “by 2020, the preparing for re-use, recycling and other
material recovery, including backfilling operations using
waste to substitute other materials, of non-hazardous
construction and demolition waste excluding naturally
occurring material defined in category 17 05 04 in the list
of waste shall be increased to a minimum of 70% by
weight.”
Waste Framework Directive
• Will this be a driver for greater ambition on CD&E
waste in the UK? Possibly not.
• Commission yet to set precise rules for measurement
of target.
• Possible Commission study into C&D waste.
• Commission can by 2014 propose additional targets
for specific waste-streams if overall target unlikely to
be met
Economic instruments and regulation
• Various fiscal and regulatory measures are already
driving up resource efficiency
- Landfill Tax
- Aggregates Levy
- Site Waste Management Plans
- Code for Sustainable Homes
- BREEAM
Site Waste Management Plans
• SWMPs have raised the issue of resource use and
waste up the agenda;
• Lots of information for business, less so for local
authorities;
• Oversight and enforcement important
• Full review of the legislation in 2011/12
• Somre requirements through planning
• SMARTWaste Plan is a free tool to assist

Code for Sustainable Homes
• Launched in December
2006
• Mandatory for all new
homes in England
• 1 to 6 star rating
• 1 = above Building
Regulations
• Licensed by BRE
• Developed from EcoHomes
CSH: Construction Site Waste Management (Was 2)
Criteria
Mandatory SWMP if project value over
£300,000 (lower value

Halving Waste to Landfill Commitment
• WRAP’s voluntary agreement provides a clear
process to deliver the 1/2W2L target.
• They will be working across the sector to support
implementation over the next three years
• A growing number of construction clients and
practitioners are making the commitment and setting
targets with their supply chains
Range of voluntary action underway
• Additional action under umbrella of Sustainable
Construction Strategy
• For example, 20% reduction in construction packaging
waste (Construction Products Association)
• Extension of Plasterboard Voluntary Agreement
• Resource plans for joinery and flooring sectors
• Defra product roadmaps for plasterboard and windows
• Creation of a new Construction Waste Group under
Strategic Forum is helping to co-ordinate action

Construction Resources and Waste Roadmap
• Launched July 2008
• Provides framework for change:

targets
– How will we get there = actions
needed
• Provides a vehicle for change with
stakeholder buy in
Roadmap targets

Halve the amount of (non-aggregate) construction
waste produced by 2015
Target 2
Halve the amount of construction, demolition and
excavation waste going to landfill by 2012 (as in the

Conclusions
• Construction and demolition remain high priority
sectors for sustainability, waste prevention, and
resource efficiency
• A mix of economic, regulatory, voluntary and advisory
measures will be needed to reach new national and
EU targets
• The economic downturn means this agenda is more
important, not less.
• Innovative research being undertaken
• More requirements for better data to under pin policy
