Key Drivers

• Legislation
• Landfill Directive
• Hazardous Waste
• Duty of Care
• Fly-tipping
• Policy
• Code for Sustainable Homes
• Site Waste Management Plans

Fiscal measures Landfill Tax Aggregates Levy
5
Client requirements

• Increasingly requiring improved environmental
  performance and evidence
• Specifying use of waste monitoring and targets
• Use of EcoHomes and BREEAM
• Central Government Procurement Policies
• Code for Sustainable Homes

EPIs and KPIs

• Environmental Performance Indicator
• m3 of waste per 100m2 floor area
• Key Performance Indicator
• - m3 of waste per 100,000
• Based on limited SMARTStart figures in 2004
• Average KPI 84.4 (residential)
• Average EPI 11.7 (residential)

10
National construction waste benchmarking programme

• Defra RD Autumn 2005 industry advisory group
• Set minimum reporting guidelines
• Create focal point for collecting data website
• Target of 1000 sites over 2.5 years
• Construction, refurbishment and demolition
• Residential, commercial, leisure, education etc..
• Set EPIs for comparison e.g. m3 waste/100m2
• Predict for site, company, local, region and
  national
• Resource management planning, building regs,
  contractual targets etc..

Common construction key waste products

• Plastic packaging
• Cardboard
• Timber pallets
• Insulation
• Plasterboard
• Timber general
• Timber packaging
• Blocks
• Bricks
• Miscellaneous

12
Common causes of waste

• Off cuts
• Recyclable packaging
• Temporary materials
• Clearing site
• Reusable packaging
• Excavation material
• Excess deliveries
• Unsuitable storage

13
Lessons learnt from GMV and other sites

• Establish a company/ site benchmark
• Appoint waste champion
• Talk to suppliers returnable packaging
• Monitor and publicise waste reduction performance
• Contractually oblige sub contractors to
  participate
• Identify key waste products and implement
  reduction plans
• Co-ordinate site safety with waste minimisation
• Download GMV Best practice guides from
  www.smartwaste.co.uk

14
Reduce flytipping

• Estimated cost of flytipping 100 million per
  year (EA)
• Reported flytipping increasing due to
• Increased disposal costs, Increased awareness/
  reporting
• Rise in organised environmental crime
• From April 2004 flycapture EA and LA web
  based reporting system
• CD waste 20 flytipped material (higher in
  SE)
• Legitimate contractors at cost disadvantage
• Proposed tagging to reduce flytipping esp.
  Hazardous waste

15
Reduce hazardous waste

• 5 million tonnes produced in England and Wales
• 1.3 million tonnes from CD waste and asbestos
• July 2004 end of co-disposal hazardous and non-
  hazardous landfill est. 12 sites available
• Increase in waste classed as hazardous estimated
  7.5 MT treated timber, contaminated land
• Register sites producing hazardous waste
• Reduce use of hazardous construction materials
  and products
• Talk to your suppliers

16
Reuse and design for deconstruction

• Reclamation sector 3.3 MT
• Fixings and material type
• Use demolition products in new construction

17
Demolition/refurbishment audits

• Quantify key demolition products
• Optimise the potential income
• Find and develop local markets
• Identify employment opportunities
• Identify reuse on site
• Inform during the contract
• Minimise journeys
• Quantify environmental impacts

18
Closing the loop Example - post consumer flat
glass
Pristine quality of post consumer flat glass from
waste windows.
Contaminants are main barriers to end markets.
Main contaminants are masonry and ceramics
Post consumer flat glass waste back into
fibreglass Insulation. Next step, back into float
glass production maybe?

Conclusion

• Reduce Reducing waste will save money and is
  usually the best environmental option
• Recycle Waste materials can become high quality
  resources minimise contamination and add value
• Close the loop Recycled building products can
  have enhanced performance characteristics, save
  money and reduce environmental impacts
