BeAware The Technology Strategy Board part funded Be Aware 48 project published its findings in 2009. Led by BRE and the Construction Products Association, with 14 other partners, the project’s aim was to reduce resource use for any given construction product across its life cycle. The approach of getting all the relevant stakeholders in the supply chain together to focus on improving resource efficiency for a product group was a key output from this project, leading the way for the resource efficiency plans, as summarised above. 7. Exemplars, case studies Kier Group – Plasterboard waste reduction: Kier adopted several strategies at the Ipswich Hospital, Suffolk development 49 . These included using the design expertise of their dry-lining installer and supplier Knauf Drywall, reducing the number of layers of plasterboard required and limiting the types of board needed to three. Rationalising the number of board types simplified installation for the dry lining teams, reducing the scope for error and therefore wastage. Drawings were also colour coded to assist the dry lining teams. Also, a board was manufactured to specifically match the 3 m room height, eliminating a horizontal joint below the ceiling. WRAP have produced a number of case studies focussed on waste reduction, these include: • Designing out waste on a school project 50 . Here the top waste saving opportunities were 1) off site pre-engineering of walls using a cross-laminated timber system, and 2) avoiding the use of paint by leaving structural elements as finishes. • Assessing the costs and benefits of reducing waste in construction trade packages 51 . Significant savings were highlighted through targeting good practice wastage rates for the components offering the biggest savings in the value of materials wasted. • Assessing the costs and benefits of reducing waste in Refurbishment of a small retail unit 52 . This concludes that whoever takes the risk for the supply of materials will get the cost savings. This is normally the trade contractor, or the main contractor for bulk products such as aggregates. The extent of waste is rarely reconciled with the original order, meaning that trade contractors often do not know how much waste is costing. To convert this reduction in waste into a reduction in price (for the contractor or client), the trade contractor will need to 1) include a reduced wastage rate in their tender (for more competitive pricing on a lump sum tender); or 2) procure less materials, therefore save money, and share this up the supply chain (open book tender). 48 Download sector reports on Modern Methods of Construction, Polymers, Precast Concrete and Timber Windows from www.bre.co.uk/page.jsp?id=707 49 Kier Green Apple Awards 2007 Plasterboard or Plasterbarred? 50 www.wrap.org.uk/downloads/Holy_Trinity_School_design_case_study_-_AG.0f036048.9691.pdf 51 www.wrap.org.uk/downloads/Brick_block_trade_package_CBA.53ecadac.7003.pdf 52 www.wrap.org.uk/downloads/Small_retail_refurb_CBA.f3c91a8f.7009.pdf 131

Current National Statistics Each year, the construction industry contributes a large amount of waste to the municipal solid waste stream (MSW). Quantifying this annual waste production is an inexact science. The most thorough attempt to estimate the total tonnage of Construction and Demolition (C&D) waste was made by Franklin Associates in 1998 when they published their report for the Environmental Protection Agency (EPA). This report provided a reasonable estimate of tonnage of C&D waste generated by residential and non-residential demolition, renovation and construction for the year 1996 (Franklin, 1998). Chini and Bruening estimated the tons of C&D waste produced during the year 2000 by utilizing the U.S. Census information for the year 2000 combined with research statistics taken directly from the Franklin Associates Report (Chini and Bruening, 2005). EPA updated the report for the 2003 C&D waste statistics and published it in 2009 (EPA, 2009). Tables 1-3 show the total C&D waste generated for the year 1996, 2000, and 2003, respectively, and Figures 1-3 are graphical representation of residential, non-residential and total wastes generated in these years.
