  1. CONSTRUCTION AND DEMOLITION WASTE - THE GRIM FACTS Karin Black Welsh Assembly Government Waste Strategy Unit

  2. Why the focus on construction? - I • The UK construction sector uses over 420 million tonnes of material resources and converts 6,500 hectares of land from rural to urban use each year • 13 million tonnes of C&D waste is material delivered to UK sites but never used • Construction, Demolition & Earthworks produce ~ 6 million tonnes/yr waste in Wales • ~20% across E&W hazardous waste produced is from this sector

  3. Why the focus on construction? - II • 90% virgin aggregate minerals extracted used in construction - <1% new buildings uses reclaimed materials • Energy used in constructing and using buildings represents approximately 50% of UK greenhouse gas emissions. • ~10% of UK energy consumption is used in the production and transport of construction products and materials

  4. Waste Arisings in Wales Total arising of controlled waste = 17.4 million tonnes –site returns 07 Source: Environment Agency Wales & Welsh Assembly Government

  5. MANAGEMENT OF 9.9m t CONSTRUCTION AND DEMOLITION & EXCAVATION WASTE (AGGREGATE ONLY) IN WALES - 2005 Source : Welsh Assembly Government C&D waste survey 2005 covering aggregate & inert waste

  6. Fly-tipped commercial waste -- Flycapture data (2006/07)

  7. Waste streams typically produced at a construction project (CRIBE 2003)

  8. Who can help? - TEAM WALES • Constructing Excellence Wales (CEW) is the body to co-ordinate construction activities in Wales • WRAP, Envirowise and BRE all offer SWMP support • WAG funded the largest waste construction survey ever -results due in October 2007

  9. TEAM WALES • The EA C & D survey will tell us- • How much waste produced from the construction and demolition companies, what type of waste, how the waste is managed, for example, by landfill, reuse, etc., and where it goes, how much it has cost to companies. • This should help in inform the review of the Wales Waste Strategy and targets for the construction sector AND site waste management plans • EA construction tool

  10. TEAM WALES- Where there’s muck there’s brass! • Examples of good resource management • Demolition of a hospital- Ballantyne Homes with at least 90% of materials from this demolition job were reused or recycled on site. Even the old hospital beds found new homes!

  11. WAG -putting money where our mouth is! • Invest in at least 3 strategic recycling/reuse sites for C &D wastes • Develop Wales own SWMP Regulations - with greater focus on waste minimisation and better enforcement • free environmental advice to the construction sector by WAG funded bodies

  12. WAG - putting money where our mouth is! • NEW Public Sector procurement Policy in recycled content in products • to ensure public sector build uses at least 10% secondary aggregate • Funding the work of WRAP and EA to develop the Protocols on waste/materials – E.g. Aggregates Quality protocol PAS 100 for compost

  13. And finally • “30% of materials you purchase can go to waste but you can save much of this by reducing, reclaiming, reusing and recycling” (RICS web site). • “….60-80% of builders' on site materials are reusable” (RICS web site)
